Food & Fitness After 50: Get Old and Get Better

“Just Do It may be Nike’s slogan, but it rules Kathy’s life.”

Too many people hit their sixties and say “it’s too late for me to:”

  • lose weight
  • change my eating habits
  • get fit

Kathy medalsBut, not Kathy, at age 65 she is stronger, fitter, and healthier than she has ever been. And, after she discovered Pickleball about 3 years ago, she has ramped up her fitness and dropped even more weight. She has the bling to prove her love of Pickleball; this woman has more hardware than a Home Depot!

 

A Slow and Steady Journey

Kathy’s journey to health and fitness wasn’t an easy one. She grew up on a dairy farm in rural Georgia and maintained a healthy weight throughout high school. Many young women gain some weight when they go off to college, referred to as the “Freshman Fifteen.” Kathy says, “I didn’t stop at fifteen pounds, not with late night pizza and beer, I kept on going.” She left college about 25 pounds heavier than when she started.

Right out of college she took a job with parks and recreation for a Georgia county that included St. Simon’s Island. “We worked hard and worked odd hours, so we were always eating on the run and mostly unhealthy foods.” Today, seafood is often prepared grilled but back in the day, it was all fried. “Fried oysters, fried shrimp, fried fish, and of course it came with fries” says Kathy. By the time she was approaching her 50th birthday her weight had ballooned to 255 pounds.

A turning point came when Weight Watcher’s at Work was initiated in the county. “All my buddies, like the police and fire chiefs said they would participate so I thought, why not join them?” For two years, every Friday, they weighed in and Kathy was determined that she would not see the number on the scale go up, so she stuck to the plan and lost 50 pounds. The county dropped the program, but Kathy joined a weekly Weight Watcher’s group and never missed a meeting. “I needed the accountability of weekly meetings and I eventually reached my goal of losing a total of 75 pounds.”

Excess Weight Takes a Toll on Joint Health

The years of carrying excess weight took a toll on her knees. It is well known that carrying extra body weight increases the impact of normal wear and tear of joints associated with aging. Added to that, extra body weight is associated with chronic inflammation that can also damage joints. When Kathy retired she couldn’t walk around the block without pain and the weight started to creep up. Her doctor recommended knee replacement and suggested dropping the weight she had regained to ease her recovery. So, she started back on the healthy eating pattern she learned at WW and in early in 2014 she had the first knee replaced. Her friends gave her a unique recovery present: a six-month membership at the local YMCA.

If it Doesn’t’ Kill You…..

Kathy loves to dance so she took her first Zumba class and after 10 minutes she thought she was going to die. “I looked around the exercise room to scout out exit doors to know how the paramedics would get in to resuscitate me when I had a heart attack! I said a prayer and asked God to not let me die and if I lived, I promised not to ever come back to Zumba!” But, of course, she survived and lived to dance another day, returning to Zumba three days a week. She worked with a trainer to rehab her knee and prepped for the other knee to be replaced. “The Y helped me so much and I don’t know if I would be where I am today without it.”

Pickleball Competitor

In the fall of 2016 the retired high school athletic director and football coach wanted to introduce a few people to Pickleball. He thought many of his friends would love the sport, especially those who had been avid tennis players. Kathy never played tennis so she decided to just go watch and thought, “I can do this, knee replacement doesn’t’ stop you for doing anything. You might have to make some modifications, but it should give you back your life, not stop it.”

Three years later, she plays five days a week for 2 to 3 hours a day. On Saturday she practices and in March of 2018 she participated in her first competition. Pickleball has rekindled that competitive spirit she showed when losing weight, “I don’t play for fun, I want to make the podium!” There are other reasons she loves the sport, “pickleball is very active, both physically and mentally. There is no time to think about anything else when playing unless you want to be smacked with the ball by person on the other side of the net.” She also enjoys the social aspect, saying “my circle of friends has greatly increased in my hometown and I enjoy getting to know peeps from other cities and states from playing in tournaments. I have met some great people playing in tournaments as partners and as opponents and that really adds to the enjoyment of tournament season. I have played with unknown partners from Georgia, Florida and South Carolina and now we all try to meet up when playing around the south.”

Tips for Optimal Aging

Today, Kathy and her partner own an art gallery where they can pursue their love of painting, acrylics work, and other creative ventures. “Before we left St. Simon’s Island we did a lot of craft shows and while we enjoyed it, it gets old hauling your work, setting up and tearing down for every show. We always joked we wish we could hang it up and so when we bought our gallery we named it “Hang It Up Gallery.”

Kathy’s tips for optimal aging? Just do it! “Watch what you eat, monitor your weight….(I’m a ‘scaleaholic’), stay active, and have friends. From where I was at age 55 to where I am at age 65 is just amazing; I’m in the best shape of my life and I plan to keep getting better.”

Food & Fitness After 50: Strategies for Losing Weight and Maintaining Weight

Strategies for losing weight and maintaining weight are not the same!

dietWeight loss is a national obsession and even older women are seeking the perfect weight loss plan (one that usually promises quick weight loss without cutting calories or being active!) We are bombarded with social media images (thanks, Instagram) of flawless women of all ages and magazine covers of swimsuit clad celebrities who never age (thanks, Botox, professional make up artists, and Photoshop). So, it is no surprise that the number one question I’m asked is about weight loss.

As women age, biology works against us to lose or even maintain our weight. As estrogen levels decline body fat stores increase and more fat is stored in the abdomen (the dreaded “belly fat”) and we have less fat in the periphery (arms and legs) as it migrates to the middle. And, if we do manage to lose weight, biology gives us another punch by slowing metabolism and ramping up hunger hormones (for a great overview of the biology of weight loss check out this link.)

So, what’s a woman to do? Let’s give three tips for losing weight and three more for keeping it off.

#1: Move the focus off weight and onto health. A quick weight loss plan might make a visible change on the number on the scale but could have lasting negative consequences for your muscle and bone. A focus on body composition management (as we talked about in this post ) instead of weight loss is the better goal. Make changes that you can live with for the rest of your life. You may think, “I can give up carbs forever,” but, trust me, you can’t, and you don’t have to.

#2: Stop thinking you can out exercise a poor diet. Exercise during a weight loss plan is important to preserve muscle mass and bone, but by itself it won’t do much for weight loss unless you are an ultra-marathoner. Every year, the Kiwanis Club in my town sponsors a 2-day bike ride, Challenge of the Centuries, comprised of rides of 30, 60, and 100 miles. Following the ride, most visit the street festival to celebrate. So, if a 170-pound man cycles 14-15 miles per hour for 2 hours (about a 30-mile bike ride) he will burn about 1500 calories; sounds great but if after the end of the ride he eats BBQ pork sandwich with a side of coleslaw, fries and sweet tea he has consumed about 1500 calories and I’ll bet it won’t take him 2 hours to eat the meal.

diet1#3: If you need structure instead of a short-term fix, take the long view and consider a plan like The State of Slim. The program was developed by weight loss researchers at the University of Colorado Anschutz Medical Center. It’s called State of Slim because Colorado has the fittest and leanest population in the U.S. This 16-week program can help you lose weight and provides the tools you need to keep the weight off. One of the program developers and currently Chairman of Nutrition Sciences and Director of the Nutrition Obesity Research Center at the University of Alabama, Birmingham , Dr. James O. Hill, says that program provides what people are looking for in a program. “In the short term, it provides satiety to keep hunger down, in the long-term it provides not only satiety but weight maintenance, and the lasting legacy is that improves overall health, specifically cardiometabolic health.”

When it comes to weight maintenance, a new set of tactics are needed.

#1: “Diet drives the bus in weight loss, but in weight maintenance diet goes in the back seat and physical activity drives the bus,” is how Dr. Hill and his colleague, Dr. Holly Wyatt sum it up. A recent study published in the journal Obesity showed that high levels of physical activity are found in individuals who maintain their weight after a substantial weight loss. To avoid regaining weight, exercise is paramount.

#2: Eat high quality protein foods to help suppress hunger and preserve muscle mass. With higher levels of physical activity, protein can help repair muscle damage after exercise and provide the building blocks for muscle protein synthesis. High quality protein choices include lean beef or pork, poultry, fish and seafood, and for the vegetarians, soy protein.

#3: Take a page from those who have lost weight and maintained the weight loss. They self-monitor, practice dietary restraint, eat breakfast, and as stated in #1, have high levels of physical activity. Dietary restraint isn’t the same as dieting; but it helps to be mindful of your food choices and when you overindulge don’t wait until Monday or January 2 to start back on eating healthfully.

Food & Fitness After 50: Don’t Let the Old Man In

In Food & Fitness After 50 we discuss food and fitness, of course! But, we also have a section on being well and the importance of managing stress, getting sufficient sleep, and enjoying social connections. Another aspect of being well is our attitude or mindset toward aging. As May is Older American’s Month it is a good time to consider an attitude adjustment. In this post, Dr. Bob Murray presents the case for “not letting the old man (or woman) in!”

This post was written by Dr. Bob Murray, co-author of Food & Fitness After 50.

During a golf outing in 2018, when country singer Toby Keith asked film legend Clint Eastwood what keeps him going strong at age 88, Clint responded, “I get up every day and I don’t let the old man in.”  Toby soon turned that response into a song.

The opening lyrics are these: old man

I want to live me some more

Can’t leave it up to him

He’s knocking on my door

 And I knew all of my life

That someday it would end

Get up and go outside

Don’t let the old man in

 Many moons I have lived

My body’s weathered and worn

Ask yourself how old you would be

If you didn’t know the day you were born

(Toby Keith, ShowDog-Universal Music, 2018)

Is slowing down the aging process simply a matter of keeping a young mind-set, not letting the old person in?  Happily, there is evidence that this might just be the case.

In a 2014 article in the New York Times, writer Bruce Grierson addressed the question, What if aging is nothing but a mindset?  Grierson highlighted the work of Harvard psychologist Dr. Ellen Langer who devoted much of her career to studying how our minds affect our bodies.  In one unique study, eight men in their 70s spent five days living in an environment that evoked 1959, a year when the men were in their 40s and 50s.  Their housing had no mirrors and the furnishings, television shows, movies, magazines, and clothing were all vintage 1959.  Measures taken before and after the men’s five-day stay showed improved flexibility, manual dexterity, and better eyesight compared to a control group of men in their 70s who led their normal lives.  Dr. Langer observed that the men had “put their mind in an earlier time and their bodies went along for the ride.”

It turns out that our mind-sets about aging develop far before we become older adults.  When we are young, we all develop perceptions of aging that we carry with us throughout life, refining those perceptions as time goes by.  Once we reach whatever we consider “old age”, we accept those stereotypical mind-sets without ever questioning their accuracy.  To make matters worse, we and others can be guilty of reinforcing and perpetuating those long-held perceptions through seemingly innocent comments such as:

  • “Oh, I must be having a senior moment,”
  • “You look much younger than that,”
  • “Hey, I’m still sharp.”

old womanA 2002 study on 660 people ages 50 to 94 reported how negative perceptions of aging affect longevity.  The researchers reported that older people who had positive mind-sets about aging lived an average of 7.5 years longer than those who harbored negative perceptions of aging. If positive mind-sets about aging can truly prolong life expectancy by over 7 years, that is an incredible incentive for all of us to reevaluate how we have allowed ourselves to think about our own aging.

Dr. Manfred Diehl from Colorado State University is an expert on how perceptions of aging affect the aging process and his notion of successful aging is one that combines a low risk of illness and disability with high mental and physical functions and an active, positive social life. (For a PDF of Dr. Diehl’s slide presentation on Optimimizing Successful Aging, click here.)

Dr. Diehl also notes that successful aging involves not only maintaining a positive mind-set but also being physically active every day, learning new things, eating healthfully, avoiding or at least minimizing bad health habits (e.g., smoking, inadequate sleep, over-eating, etc.), and staying connected with friends and family.

A positive mind-set might not mean everything when it comes to successful aging, but it surely means a lot.  And successful aging is not simply a matter of feeling invincible because that mind-set can lead some—young and old—to avoid a visit to the doctor when one is absolutely necessary.

Perhaps the best news in all of this is that a positive mind-set about aging costs us nothing more than changing whatever negative perceptions we might have been harboring.  When scientists, a movie star, and a country music singer all agree that it helps not to let the old man in, that advice seems good enough for all of us.

Food & Fitness After 50: Diet and Cancer Connection

Vancouver grandson Michael (1)
Alice with her grandson

Alice, in her early 60s, talks the talk and walks the walk when it comes to understanding the connection between diet and cancer. I interviewed her about her personal journey to optimal aging and what we should all know about diet and cancer. She is the Senior Director for Nutrition Programs for the American Institute for Cancer Research (AICR) and for the past 10 years, she has developed and coordinated nutrition programming and communicators for the Institute.

Tell me about your path to your current work with AICR.

For many years I worked in college health, first at Stanford and then for 16 years at the University of Georgia. In my role as the Health Center nutrition provider, I was a staff of one, so I learned to do everything, from student counseling to communications to working with a team of health professionals to keep the students as healthy possible. When my husband took a job in the Washington DC area I wasn’t sure what direction I wanted to go. I knew about AICR and when a position came available for nutrition communications, it turned out to be the right job at the right time for me. An important part of my job is keeping health professionals up to date on the evidence surrounding diet and cancer and that really appealed to me. Doctors, nurses, physical therapists, and other health professionals spend a lot of time with patients, but they don’t have adequate nutrition training. By helping them understand evidenced-based information we hope they pass along sound nutrition information when they talk to people.

Has working with AICR changed the eating habits of your family?

We’ve always eaten healthfully but we made some changes when I learned more about the diet-cancer connection. We were always a brown-bag lunch family, but I stopped making sandwiches with processed deli meats as our guidelines suggest eating less red and processed meat to reduce cancer risk. We adopted AICR’s simple rule: the 2/3 and 1/3 plate rule, that is to make 2/3 or more of your plate whole grains, beans, fruits, and veggies and 1/3 or less animal protein. That is a simple rule that is easily followed. My daughters are now in the thirties with their own families and they are proud of their nutrition savvy as they plan meals for their families.

I hear many older adults say, “it’s too late for me to prevent cancer, the damage is done, so why bother?” What would you say to that idea?

It is simply not true….it is never too late, or too early, to lower your risk for cancer. It is our choices over time that matter most. When you start choosing healthier foods, like a black bean, tuna or salmon burger instead of a bacon cheeseburger, you will reap health benefits. Lowering blood pressure, reducing blood sugar and insulin levels, losing a few pounds, and decreasing inflammation changes your body’s environment and that can reduce cancer risk. You will put yourself in a better position to remain healthy through the foods you choose.

The AICR has so much helpful information on the website, but is there one site that you think everyone should know about?

I love our New American Plate Challenge. It’s a 12-week, free, interactive challenge that helps you:

  • Learn to eat a healthy, flexible plant-based diet
  • Become more physically active
  • Model a healthy lifestyle for your family
  • Complement your current healthy weight/ lifestyle program

When you sign up you’ll receive a weekly challenge for 12 weeks, with support emails for motivation, along with tips, tools, and recipes to help you meet the challenge. There is also support from a private Facebook community. We’ve reached thousands of people with the challenge. Instead of celebrity challenges to give up carbs for a month, why not challenge yourself with something that will benefit you for a lifetime?

We’ve been talking about cancer prevention, but there is also a wealth of information for cancer survivors on your website. As a 13-year breast cancer survivor, I appreciate the science-based information on your website as compared to the science fiction that is circulating on the Internet.

We are learning so much about nutrition for cancer survivors. We encourage survivors to follow the same cancer prevention guidelines for everyone. Emerging research shows that mortality rates are lower for cancer survivors when they follow our guidelines. We have a program, AICR iTHRIVE for cancer survivors that provides helpful information and specific, doable steps to take related to all dimensions of wellness.

What are your keys for wellness as you age?

parkrun with husband Michael (1)
Alice and her husband at Park Run event

Besides eating healthfully, I’m physically active and my activity has evolved over the years. When I was on a college campus it was easy to exercise by taking advantage of the student and staff fitness facilities and I played a lot of tennis on UGA’s courts. When I moved to DC a big part of my daily physical activity came from using public transportation on my commute. Walking to bus or train stations adds activity every day. And, DC is such a great walking city.

My husband is a bird watcher, so we love to hike. And, we discovered Park Run USA, free, weekly timed 5K (3.1 miles) walk/run events. We love spending Saturdays with this great community and I just completed by 50th park run. It is more than exercise…it is fun, and we’ve bonded with many others who show up each week to participate.

The community aspect of the weekly run is another important part of aging well. Finding your tribe, be it community, church, political, or otherwise, contributes to the social support that we all need as we age.

And, lastly, I maintain an intellectual curiosity to learn new things. In the field of nutrition there is always something new to learn and I’m also intrigued by technology and how to use the many tools to communicate health, nutrition, and fitness information in as many ways as I can.

What challenges have you faced as you’ve aged?

Probably the biggest personal challenge is time to do everything I want to do! I work full-time and have a 45 minute to an hour commute to and from work, am inclined to want to be involved in many things, but find I tire a bit more easily. That could be related to over-committing. I certainly don’t stay up as late as I used to!

A professional challenge is the amount of information, and much of it is misinformation, about nutrition. At AICR I hear so many myths that just won’t die! We have a section on our website Healthy or Harmful to help dispel the most common myths, such as soy is harmful for cancer survivors.

Any words of wisdom for others?

Granddaughter (1)
Alice with her granddaughter

I encourage people to get out of their echo chambers and spend time with people of all ages. I love seeing how my daughters navigate the world for their children; it is so different than when I was their age. Many of my co-workers are younger and I do enjoy both learning from them. I feel younger when I can work effectively with people of different generations.

I also think that although many people know what healthy food choices are, we, as dietitians, need to understand the behavioral issues at play that influence people to make the choices they make. I want to better understand how we can tap into behavioral strategies to keep us all healthy for as long as possible.

Food & Fitness After 50: Avoiding “Refined” Grains? Think Again

I originally wrote this post for the Grain Foods Foundation and I thought the information was valuable for my readers. I hope you think so, too.

Whole grainsMost likely you’ve heard someone say, “I’ve cut all refined and processed foods, including white bread, from my diet.” Considering the definition of refined means “free from impurities, fastidious, or cultivated,” it’s curious that refined grains have taken on a negative connotation. What if removing refined grains was not necessary for good health and could contribute to having fewer healthful nutrients in your diet?

Dr. Glenn Gaesser, Professor of Exercise Science and Health Promotion and Director of the Healthy Lifestyles Research Center, Arizona State University, wanted to find out why refined grains are viewed as unhealthy by so many people, including recommendations from the 2015 Dietary Guidelines for Americans Committee (DGAC). In a recent paper, Professor Gaesser uncovered several noteworthy facts and posed several questions:

  • Recommendations to increase whole grain intake to reduce risk of many chronic diseases, including obesity, is clear. “There is rock solid evidence for the benefits of eating whole grains,” says Dr. Gaesser, yet only 2% to 7% of Americans meet the recommendation to consume at least one-half of grains from whole grains.
  • While the DGAC recommends consuming half of grains from whole grains and reducing the intake of refined grains, the committee only reviewed evidence that looked at dietary patterns, not refined grains specifically.
  • An “unhealthy dietary pattern” as defined in the research studies evaluated by the DGAC included red and processed meat, sugar-laden foods and drinks, French fries, full-fat dairy foods, and refined grains. What if refined grains are guilty by association with the other foods in this unhealthful dietary pattern?
  • Refined grains include not only staple foods, like bread, rice, cereal, and pasta, but also cookies, cakes, doughnuts, brownies, muffins, sweet rolls, and even pizza! Are all refined grains created equal when it comes to health effects?

Untangling the evidence

Infographic-Dont-Refrain-Eat-Your-Refined-Grains-e1554487212408Looking at multiple studies, called meta-analyses, that included 32 publications with 24 distinct groups of people, refined grain intake was not linked to an increase risk of heart disease, high blood pressure, stroke, type 2 diabetes, cancer, or obesity. In fact, one meta-analysis reported that higher consumption of refined grain was associated with a 5% lower risk of death from any cause. But you wouldn’t know that from the headlines blaming refined grains on all the world’s ills.

The “eat-only-whole-grains” message has become predominant in nutrition reporting. It is typical to pit foods against each other, to crown one food as good and healthful and another food as bad and unhealthy. However, the evidence to support that dichotomy for whole and refined grains doesn’t hold up upon further scrutiny. Dr. Gaesser’s investigation found that eating up to six or seven serving of refined grains does not increase the risk for many of the chronic disease affecting Americans.

An unintended consequence

While refined grains have been demonized, it is useful to remember that refined grains contribute more than just energy (calories) to our diets. Refined grains are enriched or fortified (see sidebar for definitions) with B-vitamins and iron. Eating refined grains can alleviate shortfalls of thiamin, riboflavin, niacin, and iron.  Folic acid, a B-vitamin needed for healthy nerve and spinal cord development for babies, is found in refined grains and these grains are the largest contributor of folic acid in the diet. Refined grains also contribute dietary fiber, a nutrient sorely lacking in the diets of most Americans. “Grain foods contribute about 55% of all fiber in the American diet and about 40% of fiber intake comes from refined grains,” says Professor Gaesser.

Putting it all together

What does this research mean for you? First, it is helpful to realize that you should know your stuff before you cut. There is no reason to cut refined grains from your diet.  Enjoying up to seven servings a day will contribute to nutrient intakes of several vitamins and minerals, and dietary fiber, and will not up your risk of disease.

It is also useful to think about refined grains in two distinct categories:

  • Staple grains, such as bread, rolls, rice, and pasta
  • Indulgent grains, such as cakes, cookies, pies, doughnuts, and other sweet desserts

6QMJWpKM.jpeg

Eat more grains from the staple category and less from the indulgent group. The sweet, indulgent group of grain foods contain higher levels of fat and sugar than the staple grains.

Continue to include whole grains in your diet, but there is no need to eliminate the refined, staple grains.

DEFINITIONS

Grain+anatomyWhole grains: A grain containing all three parts of the grain: the bran, germ, and the endosperm. Whole grains contain fiber, antioxidants, the mineral magnesium, B vitamins, and plant compounds called phytonutrients that have many healthful properties.

Enriched grains: Enrichment is the process of replacing nutrients that were removed when the whole grain was processed. Enriched grains have B-vitamins niacin, riboflavin, and thiamin, and the mineral iron added back to the grain at levels similar to the original whole grain. About 95% of white flour is enriched; therefore breads, pastas, cereals, rolls, tortillas, and pretzels made from white flour are enriched with nutrients.

Fortified grains: Fortification is the addition of nutrients to a food where they are not naturally occurring. Milk is fortified with vitamin D to help the naturally occurring calcium be better absorbed. Grains are fortified with the B-vitamin folic acid at two to three times the levels found in the whole grain to help reduce birth defects.

Refined grains: Grains that have been processed to remove the bran. In the U.S. the terms refined, enriched, and fortified grains are used interchangeably.

Food & Fitness After 50: Pickleball and Pickle Juice? What you need to know to stay hydrated

“The human body is basically a leaky bag of water with legs.”

 

Dr. Bob Murray

 

helene-b
My friend, Helene, playing pickleball at our local YMCA

April is National Pickleball Month! Did you know it is one of the fastest growing sports in America? Pickleball has been described as mashup of ping pong, tennis, and racquetball. If you’ve never seen pickleball in action, here is a clip to introduce you to the sport.

Because so many older adults have taken up the sport (it is so popular at my YMCA the parking lot is often overflowing!) we’ve been asked about hydration strategies. To answer your questions, I turned to hydration expert, friend, and co-author of Food & Fitness After 50, Dr. Bob Murray. Dr. Bob was the director of the Gatorade Sports Science Institute for over 20 years, so he knows a thing or two (or maybe a hundred) about hydration.

I’m a recreational pickleball player who plays for 1-2 hours with plenty of breaks, but my husband is a competitive player and may play 3-4 hours a day, several times a week. How do our hydration needs differ? 

The volume of fluid we need to drink each day varies widely due to several factors. Body size, the environment in which we live, our natural predisposition to sweating, and how much physical activity we do help determine how much fluid we need to stay well hydrated. For example, a large person who works up a sweat in a warm environment might need to drink two gallons of fluid (256 oz) over the course of a day to stay hydrated whereas a small individual who stays indoors and just putters around during the day might require only two quarts of fluid (64 oz).  As a rule of thumb, we all need to consume at least 2 to 4 quarts of fluid each day and for those who sweat a lot, that volume can sometimes exceed 10 quarts each day.  Another rule of thumb is that about 20% of our daily fluid needs comes from the foods we eat (most fruits and vegetables have especially high water content), while the remaining 80% comes from the various beverages we drink. In that regard, all beverages count toward our hydration. Colas, coffees, teas, and yes, even beers and wines, can contribute to keeping us hydrated (although beer or wine might affect the hand-eye coordination needed for pickleball, so save that beverage for post-play.) The only exception is shots of alcohol because the high alcohol content promotes the loss of urine. During physical activity, the loss of sweat can range from as little as 8 ounces each hour to over 60 ounces per hour in those who sweat heavily. That’s a lot of fluid and it is best replaced during physical activity by drinking at regular intervals.

pickleball-clipart2play both indoors and outdoors, any difference in hydration advice? 

The best advice is to drink enough during physical activity to minimize dehydration because from both a health and a performance standpoint, it is always better to be well hydrated than even slightly dehydrated.  Depending on conditions, we can lose a lot of sweat during indoor or outdoor exercise, so it’s wise to keep fluid nearby anytime we work up a sweat.

I play outdoors and just drink water and then when I got home I drink diluted fruit juice. Is that a good hydration strategy? 

The best hydration strategy is to drink enough to minimize weight loss during physical activity, without over-drinking. If the combination of water and diluted fruit juice accomplishes that, then that’s a good hydration strategy. How do we know how much to drink during exercise?  On days when you know you are going to be sweating, weigh yourself just before exercise and then again soon after. If you’ve lost more than a pound or two, that’s a pretty good sign that you need to drink more to prevent performance-sapping dehydration.  If you’ve gained weight, that’s a clear indication that you drank too much and can do with less.

pickleball (1)When I play in pickleball tournaments, and I win, I continue to play. My first match is at 8 AM and it may last 45 minutes or so. If I keep winning, I may play 5-6 matches. Often, I will sit out for extended periods of time waiting for a court or for a match to end, so may not end up playing my last match until late afternoon. Any advice for staying hydrated during the long tournament days? 

This is a great example of conditions where daily fluid needs will be very high.  Drinking during the games to minimize dehydration will be vital to staying hydrated, as will drinking enough between games to ensure that you begin the next game well hydrated.  Under these kinds of circumstances, it is best to rely on a variety of fluids including water, sports drinks, and juices to help you stay hydrated.

Can I over-consume electrolyte drinks? How do I how much is too much?

Typical sports drinks do not contain enough electrolytes (minerals) to pose a risk of over consumption.  Some athletes have overdone electrolyte supplements such as salt tablets or electrolyte powders and, in those cases, upset stomachs and nausea can result and those symptoms are usually enough to make people stop taking them before serious medical problems can occur.  One of the benefits of relying on sports drinks rather than just plain water is that the electrolytes in sports drink aid hydration by helping us drink more and lose less (as urine). The electrolytes in sports drinks promote the drive to drink and we retain the fluid more than when we drink plain water.

pickleballSeems like pickle juice was made for pickleball….is it a hydrating beverage? I heard the acid in the pickle juice can stop cramps. True?

Pickle juice definitely contains electrolytes, but most people can’t drink enough pickle juice to stay well hydrated. It is true that pickle juice has been shown to reduce the duration of muscle cramps, so if you are prone to cramping, you might give a shot of straight pickle juice a try the next time you feel a cramp coming on.

I open a mustard packet and squirt it my mouth when I start to get cramps…I’ve heard the turmeric in the mustard stops cramps. Is that true?

There are lots of “cures’ for muscle cramps that include everything from eating a packet of mustard to pinching your top lip.  The latest research shows that cramps can be stopped or reduced by stimulating receptors in the mouth, throat, and stomach that in turn reduce the excess nerve activity that causes cramping. Pickle juice and mustard both fit that description, although stronger spices such as capsaicin, ginger, and cinnamon might be more effective. Turmeric is an anti-inflammatory that gives mustard the yellow color, but it is not known to halt exercise-induced muscle cramps.

Food & Fitness After 50: Physical Activity is a Polypill – Say What?

Poly means many and polypharmacy refers to taking many drugs, prescription as well as over the counter, that can bring unwanted problems for older adults. Some people have shoe boxes full of prescription medicines, vitamin supplements, pain relievers, and other dietary supplements claiming to cure all ills. But, what if there was a polypill; one pill that could help us all improve our healthspan? In today’s post, Dr. Bob Murray, co-author of Food & Fitness After 50, lets us in on the secret of a polypill.

This post was written by Dr. Bob Murray

There is little doubt that regular physical activity lengthens our healthspan—the number of years when we are in good health.  Lots of research has made it clear that no medication is more effective than physical activity in helping us stay as healthy as possible for as long as possible.  For that reason, exercise has been referred to as a pollypill —a medication with multiple benefits.

A recent study in the Journal of the American Medical Association (JAMA) concluded that all the physical activity we encounter during the course of a normal day has a role in preventing heart disease.  The researchers looked at the daily physical activity habits of 5,861 older women (average age was 78) over a 5-year period and found that even light activity reduced the chances of death from heart disease.

Only about 25% of adults in the U.S. achieve the current recommendations for physical activity of 150 minutes of moderate-intensity activity (or 75 minutes of high-intensity activity) each week.  For anyone who is intimidated by the prospect of 150 minutes of moderate-intensity physical activity each week, the notion that all movement counts may well promote more light physical activity during the day.  Let’s hope that’s the case.

Walking, dusting, vacuuming, climbing stairs at home, gardening and lawn work, playing with children and pets, and similar low-intensity activities are part of everyday life for most Americans.  In the JAMA study, the older women engaged in a total of 3 to over 6 hours of light physical activity each day.  Not surprisingly, more physical activity was associated with lower risk of heart disease, a finding that is likely also true for older men, although that likelihood awaits confirmation.

exerciseAny time we get our heart, lungs, and muscles out of their comfort zones—even for a little bit—our bodies benefit.  A quick look at the list of health benefits of physical activity should be enough to convince even the most sedentary person to move more.

  • Lower deaths from all causes
  • Lower risk of heart disease
  • Lower risk of hypertension
  • Lower risk of stroke
  • Lower risk of Type 2 Diabetes
  • Lower risk of breast, colon, and prostate cancers
  • Lower risk of serious falls
  • Lower risk of complications after surgery
  • Lower risk of metabolic syndrome (includes obesity)
  • Lower risk of depression (and reduces the severity of depression)
  • Better memory and cognitive function
  • Better bone health
  • Improved quality of life
  • Greater life expectancy

Wouldn’t it be wonderful if even light physical activity conferred all those same benefits, even if to a lesser extent than more vigorous physical activity?  There is a strong possibility that is the case, although much more research is needed to confirm that educated guess.  What is known is that moving more during the day is a goal we all should embrace.

In general, Americans sit too often for too long.  Research has shown that prolonged sitting increases the risk of heart disease, type 2 Diabetes, and cancer.  Even if we exercise during the day, sitting for hours on end increases our risk of those disorders.  Happily, interrupting prolonged sitting with periodic 5-minute physical activity “snacks” counters the negative aspects of sitting.  Climbing a few flights of stairs, taking a brisk walk, or doing simple calisthenics can be easily accomplished during a 5-minute break.

Physical activity is indeed a polypill that can help us lead longer, happier, healthier lives and the fact that all movement counts helps make it easier for all of us to keep moving toward a longer healthspan.

Food & Fitness After 50: Is 70 the New 40?

“The strong live long!”

ChicagoI recently returned from Chicago from the annual American College of Sports Medicine Health & Fitness Summit. My friend and co-author of Food & Fitness After 50 , Dr. Bob Murray, and I gave a talk titled “Is 70 the New 40?” Since Bob and I are closer to 70 than 65, we say YES to that question!

For those of you who have not yet reached 70, what does it take to feel like you are still 40? And, for those you who have reached your 70th birthday, what does it take to stay on the path to optimal aging?

Here are some key takeaways from our talk as well as some other experts who spoke at the conference, emphasizing what we’ve been saying along….eat well, move well, and be well!

 

#1.  Lift weights. Whether you call it strength or resistance training, maintaining muscle mass is critical to healthy aging. Our muscle mass peaks around age 25 and holds steady until about 40, but then declines about 1% per year until age 65. The loss of strength is even greater…. about 2 to 4% per year. The good news is that we can easily preserve our muscle mass and strength with a couple of bouts of resistance weight training each week.

We all know the exercise guidelines call for 150 minutes per week of moderate-intensity aerobic exercise and “also” strength train two days a week. The word “also” was troubling to key note speaker Dr. Eric Rawson. Adding strength training is almost an afterthought; it would be “nice” to do it, but it doesn’t get the recognition it deserves in preserving health. “There are under-recognized benefits to strength training,” says Dr. Rawson. Strength underpins skill and if you increase strength it helps with overall physical activity.  Think about the ability to climb stairs as an example. It takes leg strength to climb stairs which may be why so many people use escalators or elevators instead of stairs. Dr. Rawson says it’s not that aerobic or endurance exercise isn’t good, it’s just that both aerobic and strength are needed for optimal aging. “If exercise is medicine, then resistance exercise is a gateway drug,” claims Dr. Rawson.Take-the-Stairs-Instead

#2. Weight training has more benefits than building or maintaining muscle. Dr. Stu Phillips elaborated on the health benefits of strength training in his presentation.  He reviewed the most recent evidence showing that resistance training “has health-related benefits that are not dissimilar to those imbued by aerobic exercise.” Strength training reduces the risk for falls and is an effective treatment for type 2 diabetes, some cancers, anxiety and depression. Dr. Bob Murray lists many benefits from strength training in our chapter on getting and maintaining muscle and strength:

  • Stabilizing arthritic joints
  • Improving balance
  • Increasing resting metabolism
  • Increasing social interaction
  • Lowering risk of all-cause mortality
  • Lowering risk of osteoporosis
  • Lowering risk of lower back pain
  • Lowering risk of obesity
  • Accelerated recovery from illness or injury
  • Improved sleep
  • Improved self confidence
  • Enhanced self-esteem

As Dr. Bob likes to say, “The strong live long!”

#3.  Maintain your body weight and if you want to lose weight, stay away from quick weight loss schemes.

I’m a big believer in monitoring your body weight so “weight creep” doesn’t happen. No one gains 30 pounds overnight, but they do gain 1 or 2 pounds a year without realizing it and as the years go by, the pounds add up. When you find yourself wanting to lose weight, the quick weight loss plan du jour seems tempting. But, as we age, weight loss should not be the goal. Instead, “body composition management is more important than weight management to enhance successful aging,” says Dr. Ellen Evans, in her special lecture, “Helping Baby Boomers Stay Functional.”

What Dr. Evans means by managing body composition is that older adults who want to lose weight really want to lose body fat while preserving lean muscle and bone. According to Dr. Evans, “regular physical activity, especially resistance training exercise, in addition to caloric restriction attenuates the loss of muscle and bone mass loss and increasing dietary protein intake enhances this effect.” The idea that we lose lean muscle during weight loss wasn’t new to me, but I never thought about the negative impact of weight loss on bone health. There is no cure for osteoporosis, so we need to do everything we can to preserve bone mass and bone strength as we age.

So, is 70 the new 40? It can be if you manage your body composition, strength train twice a week, and also keep up your aerobic exercise.

Food & Fitness After 50: Research Roundup

Each day dozens of research studies appear in my inbox, peaking this old college professor’s interest. Last week, there were three studies that made me want to take a closer look: one published in an aging journal, one presented at an annual scientific conference, and one animal study in the journal Brain Structure and Function.  Let’s briefly talk about each one and how it might translates from the page to your plate.

Blueberries for Blood Pressure

1200-136890271-blueberriesThe blue color in blueberries is due to the presence of anthocyanins (pronounced ann-though-sigh-a-nins), a sub-group of plant chemicals knows as polyphenols. Fruits and veggies that are deeply colored red, blue, and purple are especially rich in anthocyanins. The study published in the Journals of Gerontology (gerontology is the study of aging) found that eating about a cup of blueberries twice a day lowered blood pressure similar to the lowering from taking common blood pressure meds. The effect on blood pressure was both acute (happened quickly) and chronic (over time). Researchers found that the anthocyanins relaxed blood vessels and reduced the stiffness that occurs in aging blood vessels. As we age, our blood vessels lose their elasticity making it harder to control blood pressure and increasing our risk for heart disease.

What does in mean for you?

Eat more blueberries! One cup of berries, whether fresh or frozen, has about 60 calories, making it a low-calorie addition to your diet. What it doesn’t mean is taking a blueberry concentrate supplement (yes, they do exist). Researchers note that blueberries are also rich in vitamins, minerals, and fiber and the synergistic action between them and the anthocyanins might also be a reason for their health promoting powers. So, food beats supplements!

Pomegranate: Can it juice your memory?

pom wonderfulPomegranate juice is rich in polyphenols called ellagitannins (pronounced eee-laj-ah-tan-ins). These antioxidant compounds are in plants to protect the plant, but when we eat the plant, their protectors come along for the ride. The research, presented at the 2019 meeting of the American Association for Geriatric Psychiatry, described how a daily serving of pomegranate juice improved visual learning and retention of learning in a year-long study with older adults, average age of 60. The study was a randomized, placebo-controlled, double-blind study; a design that is considered the gold standard in nutrition research. What that means is that study participants were randomly assigned to either drink 8-ounces of pomegranate juice or 8-ounces of drink that looked and tasted like pomegranate juice but contained none of the active polyphenols. Double-blind means that neither the participant nor the researchers knew who was getting the real juice or the placebo. Dr. Gary Small, director of the University of California (UCLA) Longevity Center, presented the current research at the scientific conference, building upon similar work that his group published in 2013 in the Journal of Evidence-Based Complementary and Alternative Medicine. In the 2013 study, a similar design was used but the study was short-term, only lasting one month, but the results were similar. So, the researchers wanted to know if a longer-term study would show memory benefits, and it did.

Researchers are not sure exactly what it is in the pomegranate juice that showed the positive results. One interesting theory is that the pomegranate juice works though the gut microbiome. The healthy bacteria in our gut can breakdown the ellagitannins to a compound that crosses the blood brain barrier, exerting its beneficial effect through the gut-brain axis.

What does it mean for you?

An eight-ounce bottle of pomegranate juice contains 2 whole pomegranates, so drinking the unsweetened juice gives you 650 to 700 milligrams of polyphenols. That’s a lot of good stuff in a little bottle. Pomegranate juice is tart, not sweet, so it might appeal to those of you who don’t like sweet, sugar-added beverages. Considering that most of us don’t eat enough fruit, 8-ounces of pomegranate juice is a good way to get more fruit and healthy polyphenols in our diet.

Vitamin D: Good for the Brain?

Vit DThe third study is on vitamin D deficiency on processing new information and retaining it for future recall. It was conducted with mice and I always cautioned my students to count the legs on the research subjects before considering if it is relevant to those of us on two legs, but this study is interesting in understanding vitamin D deficiency and the brain. Vitamin D is most often thought of as a bone-building nutrient because without enough vitamin D only 10-15% of dietary calcium is absorbed. Yet, vitamin D has many roles in the body, including cognition.

Older adults are considered “at risk” for vitamin D deficiency because our skin doesn’t convert sunlight to vitamin D as readily as it did when we were younger and vitamin D isn’t found naturally in a lot of foods. Some foods, like milk, are fortified with vitamin D, but many yogurts are not. (The only way to know if your favorite yogurt is fortified with vitamin D is to read the nutrition facts panel and ingredient list on the container.)  The recommended dietary allowance for vitamin D is 600 IU for those 51 to 70 years and 800 IU for those over 70. The upper limit is 4000 IU and many older adults take a supplement of 1000 IU to make sure they are getting enough vitamin D. Check with your doctor and ask if a vitamin D blood test is needed to tailor your vitamin D intake to your blood level.

What does it mean for you?

Choose vitamin D-rich foods, either naturally occurring or fortified (for an extensive list of vitamin D in foods click here.)

Bottom Line

Eat more deeply colored fruits and veggies, including blueberries and pomegranate juice, to get healthy plant compounds in your diet. And, choose vitamin D rich foods, like salmon or tuna, and fortified milk, yogurt, and cereals. Here is my breakfast plan:

  • 1 cup of Greek yogurt (choose a brand fortified with Vitamin D)
  • 1 cup of fresh or frozen blueberries and ½ cup of high fiber breakfast cereal mixed into yogurt
  • 8-ounces of pomegranate juice

While the research is promising, this breakfast may or may not improve my brain health, but it gives me a great start to the morning with three servings of fruit and a good dose of fiber in a calcium and vitamin D-rich breakfast bowl. And, did I mention it tastes great?
