Food & Fitness After 50: The Scoop on Collagen

Bob bike 2

Survey data from the Council for Responsible Nutrition (a trade association for dietary supplements) shows that 78% of adults over the age of 55 take supplements. Reasons for supplement use include overall wellness and healthy aging. It is no surprise that people are asking about one of the hottest supplements…collagen. I reached out to my friend and co-author of Food & Fitness After 50 to ask him some of your top questions about collagen. Dr. Bob Murray is an exercise physiologist and is passionate about exercise and health. He consults with many companies on hydration, protein, and supplement use in active populations, including older adults.

Let’s start with the basics. What is collagen and are there different types of collagen in the body?

Collagen-structure.800x345-wWe can think of collagen as the glue that holds us together. Collagen is the name for a large family of proteins found in the body.  In fact, there are so many types of collagen proteins that collagen turns out to be the most abundant protein in the body. Collagen proteins make up connective tissues throughout the body.  The term “connective tissues,” makes many people immediately think of tendons, ligaments, and cartilage, three good examples of connective tissues.  Muscles, skin, and bones also contain large amounts of connective tissues and therefore large amounts of the collagen proteins that intertwine to give those tissues the structure, strength, and elasticity required for the many different roles required of connective tissues. It should be obvious that the connective tissue in bone has a different role to play compared to the connective tissue in muscles or skin. That’s why so many different kinds of collagen proteins are needed throughout our bodies.

When I was younger, I remember my friends dissolving Knox gelatin in water and drinking it to strengthen their nails. Is gelatin the same as collagen?

The connective tissues of cows, pigs, and chickens are the primary source of gelatin produced for human consumption.  As a result, gelatin is rich in collagen proteins.

Is collagen a complete protein, that is one that contains all the essential amino acids needed by the body?

Collagen is an incomplete protein and is low in the amino acids that are associated with building muscle mass and strength.  However, collagen proteins are high in two amino acids—glycine and proline—that appear important in stimulating the growth of connective tissues in physically active people.

There are many claims for collagen supplements…from preventing wrinkles and strengthening skin to improving joint flexibility and strengthening muscles and bone. Is there any good human evidence that collagen supplements will help with any of those body systems?

The best way to sum up the current state of affairs is that the benefit claims for consuming collagen are long on theory and short on evidence.  That’s not to say that there isn’t some evidence suggesting benefits to skin, joints and muscles, but that evidence has yet to reach the levels of quality and quantity required to draw comfortable conclusions about the magnitude and reproducibility of the benefits associated with consuming collagen proteins on a regular basis.

It is well known and accepted that protein is needed for muscle protein synthesis, is collagen any better than simply getting more protein from whey protein or other protein-rich sources?

iStock Older man lifting weights smallMaybe, but much more research is needed to either confirm or deny that consuming collagen benefits muscle mass and strength beyond what we know occurs by increasing dietary protein intake. There are a growing number of studies that report benefits to muscle strength, joint pain, and repair of connective tissue, but there are a greater number of studies that report no benefits.  The unsatisfying answer to your question is that we’re going to have to wait and see what future research has to say,

Do you think older adults need to use collagen as a supplement?

Collagen production does naturally decline with age and there are studies that report benefits of collagen consumption in older adults.  Maybe the best news is that there is little to no risk of trying collagen supplements, aside from the possibility of spending money on something that does not work.

There are so many forms of collagen being sold…hydrolyzed, peptides, raw, undenatured and found in various forms from liquids, powders, tablets, chews and even gummies….if someone wanted to take collagen what is the form and dose that is currently recommended?

The current research indicates that the effective dose seems to be 15-20 grams of collagen per day, along with 200-250 mg of vitamin C to aid in collagen synthesis. The body seems to respond best to the presence of collagen peptides—short chains of a few amino acids—and most forms of dietary collagen contain such peptides. Look for products containing hydrolyzed collagen or collagen peptides on the label.

1800ss_getty_rf_vitamin_cI’m glad that Dr. Bob mentioned vitamin C and its role in collagen production. Vitamin C is most frequently thought of a nutrient that helps our immune system, especially fighting the dreaded winter cold, but it has a fascinating history (well, fascinating to most dietitians!). At the end of the 15th century, a disease called scurvy was the major cause of disability and death of sailors undergoing long sea voyages. Without access to fruits or vegetables, sailors developed bleeding gums, lost their teeth, had poor wound healing, and frequently old wounds would open up (called dehiscence). All because they were deficient in vitamin C and its important role in collagen production. Collagen helps anchor teeth in our gums and jawbone, as well as helping to keep skin healthy and elastic. It wasn’t until the 1930s that a Hungarian scientist, Dr. Albert-Szent-Gyorgyi, discovered and isolated ascorbic acid (a contraction of anti-scorbutic), better known as vitamin C.

Food & Fitness After 50: Fun with An Air Fryer

It all started at the beginning of the stay-at-home orders. Like a good dietitian, I took stock of what was in my freezer, fridge, and pantry and planned meals around what was on hand. I mentioned to my husband that we had some Wild Alaska Pollock and Wild Caught Cod filets in the freezer. His response? “I wish I could have fried fish. I love fried fish.” I don’t fry foods and when it comes to fish, I prefer grilling. But it made me think of air frying and with one click, the Ninja AF 101 Air Fryer was in my cart and ready to be shipped.

I have no affiliation with Ninja products but after reading some reviews on consumer websites, the product looked good and the price was right. Once it arrived, it was love at first bite. Using the cooking guide that came with the book I found coating almost anything in flour, egg, and panko breadcrumbs is delicious.

Air Fryer Cookbook for Dummies

514G1VUZdAL._SX397_BO1,204,203,200_Then, serendipity! One of my colleagues, Elizabeth Shaw (@ShawSimpleSwaps), posed a question on social media asking about favorite kitchen appliances and I didn’t think twice as I typed in “air fryer.” She had just published a book with, Wendy Jo Peterson (@Just_WendyJo) called, Air Fryer Cookbook for Dummies (John Wiley & Sons, 2020) and offered to send me a press copy.

So, disclosure, the press copy was free, and I wanted to share my thoughts on the book and the recipes. First, a brief introduction to Wendy Jo and Liz. Wendy Jo is a culinary dietitian, a writer, speaker, and recipe developer. Her clients range from military to musicians and she is known as the “Fuelin’ Roadie” for innovation with recipes. She is the author of numerous books. Liz Shaw is also a registered dietitian and her brand is Shaw Simple Swaps. She is a culinary expert and her mission is getting people to enjoy food and make small changes to reap big rewards. Please visit their websites for amazing recipes and other great food and nutrition information.

Too Many Great Recipes to Choose From!

But, back to the book. The first thing I liked about the recipes is the use of ingredients you are likely to have in your kitchen…important in a pandemic when we are not out shopping in specialty grocery stores and online delivery is hit or miss. You won’t find cold-pressed, double-filtered organic grapeseed oil or any other hard to find (and expensive to buy) ingredient in any of the recipes….thank you Liz and Wendy Jo.

I flipped through the recipes and truly I wanted to try them all, but I settled on one from each section and using ingredients I had in my house. First up was “Crispy Fried Chicken,” and it didn’t disappoint. I had thinly sliced chicken breasts in the freezer, so I cut them into strips for chicken tenders. I found that my 4-quart air fryer cooks a bit faster than the recipe times call for, so some trial to adjust cooking times is in order. I loved how crispy and golden brown the chicken turned out. Each recipe has notes, tips, and suggestion on how to vary it. We made a dipping sauce with honey and mustard, using one of the tips.

fishingOn to that “fried” fish my husband was craving. I got lucky because my brother-in-law hired a fishing guide to take them out on our lake to hook some fresh fish. As you can see in the photo, the trip was a success and we had bass filets ready for the Air Fryer. I tried the recipe, “Lightened Up Breaded-Fish Filets.” It was equally as good as the fresh salmon I had in Alaska last summer. Can’t wait to try it with my frozen filets, too.

AF FD - Tuna Melt 2
Tuna Melt

Next up was another of my husband’s favorite dishes, Eggplant Parmesan, and he declared it excellent, although he suggested we add some gooey, melty fresh mozzarella cheese next time we make it. Last night, for a quick dinner we tried the Tuna Melt and it was grilled to perfection.

Side dishes are a snap in the Air Fryer and there are plenty of recipes for veggies. The Crispy Herb Potatoes beats French Fries any day and I love the chapter on “Ten (or so) No-Recipe Recipes that Make Perfect Sides.” From Brussels Sprout to Zucchini, you can quickly make a tasty side dish to accompany any entrée. I tried the Brussels Sprouts with Bacon this past weekend and I could have eaten the entire dish by myself!

My only “fail” was in the baking section. I tried Cinnamon Sugar Donut Holes, but they were dry. Good flavor, but crumbly texture. I know I will need to adjust temperatures and times to fit my Air Fryer when baking.

Tips and Tricks

In addition to the recipes, the authors give loads of tips and tricks for using an Air Fryer. As a newbie to this device, I found helpful information to get the best results from my Air Fryer. For example, they suggest coating the basket with olive oil instead of using popular cooking sprays. Commercial cooking sprays contain chemicals that can corrode the basket, so I ordered an inexpensive mister and filled it with olive oil to keep foods from sticking.

They also recommend using a meat thermometer to insure proper cooking temperatures. I always recommend using a meat thermometer instead of guessing if the food is done. Not only does using a meat thermometer help you avoid under-cooked food, but it also prevents over cooking.

Additional Benefits for Older Adults

As many older adults find themselves empty-nesters, I think an Air Fryer is a perfect appliance for healthy, quick meals for one or two people Using it for delicious veggie sides or dehydrating veggies for chips (I have not tried the dehydration setting yet!), it is easy to use and easy to clean.

Some people describe an Air Fryer as just another convection oven, but I find it easier to use than the convection oven setting. Cooking times in the Air Fryer are faster than the oven and the food comes out crispy on the outside but tender on the inside.

I live in the south where there is an affinity for fried foods. An Air Fryer gives you the taste of fried food without the excess calories and saturated fat. Another plus is that cooking with an Air Fryer keeps the kitchen cool. No one wants to turn on a hot oven or sweat over a greasy frying pan on a summer day in Georgia.

While I am not an RVer, many of my friends are, and in the Air Fryer Cheat Sheet for Dummies the authors suggest it is a great appliance for the RV lifestyle.

If you’ve got an Air Fryer hiding in a closet, dig it out and try some of these great recipes. And, if you are like me and looking to try something new, I recommend an Air Fryer and Liz and Wendy Jo’s cookbook! A big thanks to Wendy Jo and Liz for showing me all the ways to use my favorite new purchase.

Food & Fitness After 50: Finding the Silver Lining for Active Older Adults During the Pandemic

Food & Fitness After 50 is built on the pillars of eating well, moving well, and being well. So, when Tivity Health, the parent company of of SilverSneakers™, invited me to be a member of their scientific advisory board, I enthusiastically agreed. SilverSneakers embraces the same principles that I hold and while most people think of it as an exercise program, they have an equal emphasis on health, wellness, nutrition and connectivity.

iStock-Older couple runningNow with in-person group exercise classes on pause to stop the spread of COVID-19, how has the change affected SilverSneakers members? Researchers at Tivity Health conducted a number of surveys through the SilverSneakers newsletter on social connections, exercise, and nutrition to understand the concerns of newsletter readers. The survey provides a snapshot of an engaged community and their changing health habits. The infographic shown below (Source: Tivity Health) shows the highligts of the survey conducted between March 26-April 16, 2020. Let’s take a look at how sheltering at home is affecting older adult’s activity, nutrition, and social connections and provide tips on how to make the best of a bad situation…sort of the silver lining for SilverSneakers members.

Being Well and the Power of Social Connection

SilverSneakers Pulse Survey

Let’s start with the loss of social connection. Not surprisingly, ranked as the number one disruptor is the inability to visit with family and friends. I’m sure my SilverSneakers friends miss their coffee corner at our local gym as much as they miss the opportunity to exercise at the facility. The survey also found that limited social interaction contributed to feelings of stress and anxiety.

iStock-Older friends enjoying meal smallSocial support is big part of being well. Research from the Harvard Study of Adult Development found that participants derived their greatest happiness and joy in life from relationships. Men who were socially connected to family, friends, and community were healthier and happier, and they lived longer, than those who had less social connection. Tivity Health’s own research backs up that finding. A study published in 2018 in the Journal of Applied Gerontology found that membership in SilverSneakers not only increased physical activity but also improved health through decreased social isolation and loneliness.

The Silver Lining? Learning how to stay in touch using video chats, live streaming, or social media sites, such as Facebook Live. About 75% of survey respondents say that using various technology tools to stay in contact with friends and family members has helped bridge the physical distance. And with more use comes more confidence in using technology. Everything from religious services, to virtual bridge clubs, to reading stories to their grandchildren, older adults are embracing video capabilities and becoming more comfortable and proficient. That proves that you can teach new skills at any age.

Moving Well: Staying Active in Creative Ways

A big part of SilverSneakers is exercise, and with fitness facilities temporarily shuttered, how do older adults stay active? Survey results show that 93% of all members are still engaging is some form of exercise. Spring brings people out of doors and many find that they can still walk or bike, even with social distancing. And they recognize that activity of any kind is also exercise; from gardening to completing home projects keeps people moving.

iStock Older man lifting weights smallWhile walking is a wonderful fitness activity, we still need to balance our exercise plate with strength training and the ABCs (agility, balance, and coordination). Keeping muscles strong is always important but even more so now. Between the ages of 20 and 90, we can lose over 50% of our muscle mass due to sedentary lifestyle and sarcopenia (which means “vanishing flesh.”) For those who get ill and are confined to bed, a loss of 1% of muscle mass per day compounds the situation. The good news is that strength training just 2 days per week for about 30 minutes per session can reverse muscle loss.

older-adults-tai-chi-outside-e1505160556655Agility, balance, and coordination helps older adults stay active, reduces musculoskeletal injuries, and reduces the risk of falling. While we may never be as agile and coordinated in our body movements at 70 as we were at 20, simple exercises can help improve the ABCs. Yoga, Tai Chi, stretching, balancing on one foot, all can help improve balance.

For those who have replaced their exercise routine with only walking during this time, be sure to start slow when you do return to your pre-COVID-19 workout to avoid injury. In the nutrition world when refeeding a malnourished patient, we use the phrase, “make haste slowly,” and that applies to kick-starting your exercise routine.

The Silver Lining? SilverSneakers offers video home workouts with over 200 videos on demand, so no chance for boredom! There is also the SilverSneakers GO fitness app for smart phones, so workouts are portable. And, with Facebook Live exercise classes offered multiple times per week, activity is possible for these times. Don’t have Facebook but would still love to take part in live classes? Tivity Health recently launched SilverSneakers LIVE, where members can enjoy full-length, live classes and workshops directly through the SilverSneakers website. Create or log in to your account to see the class schedule.

Even without videos, much can be done with exercise bands. I have a set of three bands…light, medium, and heavy resistance that I use for bicep curls, triceps extensions, and shoulder exercises. I hang them on a doorknob as a visual reminder to use them every day.

Eating Well: Get Creative

iStock-Older couple making salad smallSurvey results for nutrition habits show a mixed bag. 56% of respondents report eating more home-cooked meals. Generally, cooking results in healthier meals, so that is a good thing. However, about 25% report making less healthy choices and 30% are eating out of boredom. Comfort foods are definitely “in” right now, but comfort food doesn’t have to be unhealthy food. This might be the right time to lighten up an old family favorite and there are plenty of recipe sites online to help you make substitutions, not sacrifices. Keep healthy snacks on hand so when boredom has you heading to the kitchen choose a snack of fresh fruit, yogurt, or a handful of nuts.

refrigerator-22592466The bad news is that about 1 in 5 people worry about having enough food or being able to restock their supplies. With disruptions in the food supply chain and home delivery of groceries hit or miss (or delayed) it can be a good time to do an inventory of everything in your freezer, fridge, and pantry and plan creative meals around what you have on hand. (For more on this strategy, click here and here.)

The Silver Lining? Many home delivery meal systems are offering significant discounts for meal and snack delivery. And while you may think of meal delivery such as Nutrisystem* as “diet” food, the meals are healthful and could be used to supplement what you have on hand. This is also a good time to dig out appliances hiding in a closet…a George Foreman grill, an Air Fryer, or Crockpot can be used for easy to prepare meals without a lot of fuss. Crockpot cooking can be  an especially affordable and easy way to r batch prep meals, so you can cook once and eat two or three times.

These unprecedented times have us moving in new directions, but the survey results clearly showed that older adults are resilient. We are strong and creative in finding new ways to eat well, move well, and be well. We might just find that we like those Zoom happy hours with our friends and exercising online!

*Nutrisystem is part of the Tivity Health portfolio of products.

Food & Fitness After 50: Lessons from a Late Blooming Ballroom Dancer

FoxtrotNYDF20
Chandra and Ian Folker doing Foxtrot

At the age of 55, Chandra did something that not many of us would do. Sure, we might take up weight training or pickleball, but ballroom dancing? That is exactly what Chandra did and ten years later she is competing in smooth ballroom dances…waltz, foxtrot, tango, and quick step. “Ballroom dancing is the ultimate full body and mind exercise,” she says.

A Valentine’s Day Surprise

It started with social dancing with her husband and he surprised her with ballroom dance lessons one Valentine’s Day. While he “retired” from dancing, she went full steam ahead. After working with a few different dance teachers, she found the ideal teacher, Ian Folker, and they have been dancing together for the past three years. “Ian has helped me meet my goals and competing was one of those goals. Ballroom dancing is like other sports…first you have to learn the fundamentals and then improve on that skill set with practice and repetition.”

FoxtrotNYDF20bJPG
Foxtrot

Chandra practices 4 to 5 times each week and competes on a regular basis. “Competing is intense, as intense as any sport!”  She also practices restorative yoga to help her dance movement and finds it mentally and physically therapeutic.

Functional and Integrative Nutrition

Least you think that this is her full-time job, it is not. Chandra has a private nutrition practice and has gravitated toward functional and integrative nutrition as a wholistic way to help clients reach their goals. (To learn about her nutrition practice, click here for her website, Nutrition in the Now. Prior to starting her business, she worked in clinical nutrition research at Emory University. “While running clinical trials on the role of different diets in treating breast, lung and colorectal cancer, the medical director wanted everyone working on the project to try the diets. I did and found the lower fat diet felt good for me.” The goal of functional nutrition is to identify the foods and nutrients that function to keep your body healthiest.  Chandra reminds her clients that “Food Is Your Medicine.”

Using Foods to Manage Disease

TangoNYDF20c

Chandra, the mom of 2 girls, was diagnosed with pre-eclampsia during her first pregnancy which is a form of high blood pressure. “I basically had pre-hypertension.  I was later diagnosed with Mitral Valve Prolapse.  Given these pre-cardiovascular disease conditions, I understood how important lifestyle was in managing my disease risks. I have learned to understand the way sodium and salt affect me and I am very attuned to reading labels to look for the hidden salt.” She eats a whole foods diet with minimal processing, as salt is a main ingredient used to process and preserve foods. Her favorite meal is fresh seafood; something she can readily find when she spends time in Florida or California. “Walking to the docks and buying fresh seafood as it comes off the boat makes for the perfect meal.”

She has also learned to appreciate the role of nutrition in treating disease through her yearly visits to Germany. Her daughter, a neuroscientist, introduced her to a European way of treating disease. “They rely much less on medications, as we do in the U.S., but use herbs (botanicals) and spices and food as restorative, healing agents. That approach may take longer, but they use significantly less drugs than we do and have good results.” We agreed that most Americans are quick to take a drug but slow to change their lifestyle.

Challenges to optimal aging

When I asked Chandra to identify challenges to healthy aging, she said that she is trying to live a life as stress-free as possible. Spending time with her daughters and four grandchildren makes her realize that what is important is relationships, not things. “I am really trying to declutter…we have so much but want more and more and living with less can help reduce stress.”

Chandra’s tips for healthy aging include:

  • Have a vision for your life.
  • Have a support system to help you reach your vision.
  • Live the best you can live and aim for inner peace.

And, while she didn’t name laughter as a tool for healthy aging, we laughed a lot during this interview!

P.S. The photos in the post are from Chandra’s most recent ballroom competition. “The competition was so exciting as well as overwhelming.  It was the largest US Ballroom competition this year.  For a beginner, I was pleased; of course, a little nervous, however, once I began dancing, I had to remember all my coaching instructions.  I competed from 8:30 am and my last competition was at 6:30 pm.  I was completely exhausted, hungry and so out of energy. My lesson learned, I have to be sure and fuel the night before and during!”

Food & Fitness After 50: What is Clean Eating?

A funny meme circulated among my dietitian friends. The first woman says, “I can’t eat that, I’m trying to eat clean.” The second woman (probably a dietitian) replies, “It’s banana bread, Susan, not heroin.”

clean eatingIt’s funny and sad at the same time. Many people limit delicious, healthful foods (banana bread) because they don’t fit into what they consider “clean” eating. Some people rely on the front-of-pack “free-from” claims to judge if a food is worthy…. free from sugar, white flour, gluten, additives, colors, GMOs, and on and on.  Which leads us to the concept of clean eating. Most dietitians don’t like the term because the opposite of clean is dirty and no one wants to say they are eating “dirty.”  Saying you eat clean implies a certain moral superiority to the rest us who are microwaving a frozen meal.

But it doesn’t matter if I like it or not, the term clean eating is here to stay. I counted over 70 books for sale on Amazon with “clean eating” in the title.

At a recent conference, I learned from Kris Sollid, a registered dietitian and senior director of nutrition communications at the International Food Information Council, that clean eating was the the number 1 diet trend in 2019. Some people think clean eating is diet of whole, unprocessed foods. Some people are OK with processed foods if they don’t contain artificial coloring or flavors with hard to pronounce ingredients. Other think foods labeled organic tick the clean eating box, while some ascribe a vegan diet as the only way to eat clean.

2019 Diet Trend for CR

But, when it gets down to the definition of clean eating, it depends on who you ask. “The bottom line is that while the definition isn’t clear, ‘clean’ is often used as a proxy for ‘healthy’” adds Sollid.

Hand-in-hand with clean eating is a trend in the food industry to develop “clean” labels. Many food manufacturers are reformulating products to limit the number of ingredients to satisfy consumer demand.  In many cases this is a good thing; finding ways to reduce salt by using fewer sodium-based ingredients or lowering sugar by finding the sweet spot of less sugar without changing taste are all good moves. But, when a product simply replaces sugar from sugar beets with “pure cane sugar” and makes you think it is healthier, well, sugar is sugar and just because the word “pure” is front of cane sugar it doesn’t make it a healthy ingredient.

So, instead of focusing on eating clean, let’s just focus on healthy eating. Some ways to do that are:

  • Focus on the positives in a food, not the negatives. Choose foods with nutrients that you need, like vitamins, minerals and fiber instead of focusing on sugar or fat content. Sugar and fat are important but take a wider view when choosing foods. For example, as we age, we still need bone building nutrients: calcium, vitamin D, vitamin K, and magnesium. Look for foods with those nutrients and keep in mind that not all dairy foods or plant-based alternatives to dairy contain vitamin D.
  • Ignore the buzz words like “all natural,” “real ingredients,” or “minimally processed.” They don’t mean anything.
  • Recognize the value of processed foods, like frozen berries, canned tomatoes, or ready to eat breakfast cereal. These foods provide big nutrition for little money. Amy Cohn, a registered dietitian with General Mills reminds us that cereal is the number 1 source of whole grains, fiber, B-vitamins, iron and zinc for all Americans at breakfast. And, when paired with milk, the “average bowl of a Big G cereal is about fifty cents.”
  • Don’t be afraid of words you can’t pronounce on list of food ingredients: pyridoxine hydrochloride may sound strange, but it just the chemical name for vitamin B6.

Food & Fitness After 50: Recovery After Hard Exercise

iStock-Older couple runningMany folks over the age of 50 are incredibility active: pickleball, tennis, swimming, running, hiking, and cycling are all popular with the 50+ crowd. I am often asked about hydration and recovery strategies and sometimes I hear some crazy things. So, what do you really need to help your body recover after a long, hard work out or competition? First let’s talk about two things you don’t need.

One, a new fad called “dry fasting,” or in other words, starvation and dehydration. The idea of dry fasting (no food or water) for a set period (anywhere from 3 days to a couple of weeks) is just plain dumb for everyone, but especially for older, active adults. We’ve talked about the important of hydration in previous posts, so click here for more information on the importance of hydration for older, active people. Just say no when you come across the YouTube videos of dry fasting enthusiastic followers and stick to your tried and true fueling and hydration strategies.

Another thing you don’t need is expensive waters that claim to be “smart” by changing the acidity and alkalinity (pH) of your blood. Organs, like lungs and kidneys, tightly control our blood pH in the range of 7.35 to 7.45; if gets higher it is called respiratory or metabolic alkalosis and if it is lower it is respiratory or metabolic acidosis and both are life threatening. There is no need to try to acidify or alkalize your body because your lungs and kidneys won’t let you do it anyway. The only thing “smart” about these waters is the money they are making for their promoters.

blood ph

For real recovery and hydration, here is what we know:

  • Fluids help restore body water.
  • Carbohydrates replenish muscle carbohydrate stores (glycogen).
  • High quality protein provides key amino acids for repairing muscles.
  • Antioxidant-rich beverages like tart cherry or blueberry juice provide plant compounds that can reduce inflammation and help with muscle soreness after a hard workout.
  • Omega-3s (often called fish oils) are also anti-inflammatory and most Americans don’t get enough of these healthy fats in their diets.

ERSA Norwegian food scientist, Janne Sande Mathisen, has combined all these ingredients into a new recovery beverage called Enhanced Recovery Sports Drink. The beverage contains 20 grams of whey protein with 2 grams of leucine (an amino acid referred to as the anabolic trigger), and 1600 milligrams of omega-3s. It was tricky to find a form of omega-3s that worked in solution that didn’t taste fishy.

The carbohydrate source is from fruit juices (apple, pear, and black current) to give both rapidly absorbed carbs and polyphenol-rich fruits (those antioxidant healthy plant compounds).

I was sent some samples to try and I shared them with some very active friends. The overwhelming consensus is that it is a tasty drink, not too sweet, and serving size of just a little over 8-ounces is the right amount to drink after a workout without bloating, aftertaste, or too much volume. I think it tastes like kefir; others say it tastes like a yogurt smoothie.

I like the food forward approach of this recovery drink and think it might be a good solution for combining recovery elements in to one simple-to-drink beverage. For competitive athletes who may have to undergo drug tests, the product is certified by Informed Sport to contain no banned substances that could disqualify an athlete from competition.

Disclosure: I was sent free samples of the product to try, but I was not asked to or compensated to write this post. I have no connection to the company.

Food & Fitness After 50: Is There a Best Diet for Losing Weight?

dieting

Each week Obesity and Energetic Offerings arrives in my inbox. It is a weekly roundup of research from Indiana University School of Public Health and University of Alabama Birmingham Nutrition Obesity Research Center. One of my favorite features is called “Headline vs Study,” and a recent one on weight loss diets was intriguing.

The Headline: Study Reveals the Best Diet for Actually Losing Weight and Keeping It Off.

The Study: Exploratory, observational analysis: “Small differences in metabolic outcomes were apparent in participants following self-selected diets… However, results should be interpreted with caution given the exploratory nature of analyses.”

Being a nutrition nerd, I read the study titled “Intermittent fasting, Paleolithic, or Mediterranean diets in the real world: exploratory secondary analyses of a weight-loss trial that included choice of diet and exercise,” published in the American Journal of Clinical Nutrition. Here are the key takeways:

  • Conducted in New Zealand and Australia, the current study was a secondary analysis of data from a study on support strategies for three different diets and two different modes of exercise to understand different monitoring strategies that might encourage adherence to diets and exercise.
  • About 250 individuals who were healthy and had a body mass index that classified them as having overweight were selected and screened for height, weight, blood pressure, and blood sugar.
  • Individuals could choose one of three diets: Mediterranean, Paleo, or Intermittent Fasting (IF) and one of two exercise plans (recommended national guideline for exercise or high intensity intermittent training (HIIT). All participants were given detailed guidelines for the chosen diet and exercise plan.
  • The IF plan was the most popular, with 54% of participants choosing it, followed by Mediterranean diet (27%) and Paleo (18%).
  • Only half of the participants who choose the IF or Mediterranean diet were still following it at 12 months and one-third of the Paleo dieters were following the plan.
  • Adherence to any diet rapidly declines over time.
  • No matter which diet was followed, outcomes for weight loss, blood pressure, or blood sugar were modest.
  • There is difficulty following diet in a free-living environment without intensive ongoing support.

And, this is why it pays read beyond the headline and to dig deeper to get the real story.

All of this made me think of a recent presentation from Ted Kyle, founder of ConscienHealth and LeeAnn Kindness, of Tivity Health (Nutrisystem is one of their products) on the heterogeneity of obesity. According to Kindness, “77% of adults are actively trying to improve their health and more than 120 million are actively trying to lose weight.” Over the past 12 months, consumers have tried over 18 different dietary patterns to improve their health or lose weight. Yet, as was shown in the study on the three diet patterns, it is hard to stick with the plan.

So, what is “best?” Ted Kyle reminds us that the responses to diets vary. Study data usually report outcomes as averages of aggregate data, and we all know what an average is…that means that some people will lose weight on a specific plan while some people gain weight. He showed data from a study called DIETFITS on low carb vs low fat diets…. some people lost weight on both plans, but some people gained weight on both plans. “The same is true for any diet, drug regimen, or surgical intervention and the bottom line is one size doesn’t fit all,” says Kyle.

That is why programs like Nutrisystem are recognizing that “sustainable weight management requires a personalized approach, considering age, gender, food preferences, and goals,” says Kindness.

When choosing a plan for lifelong health, find something that works for you and seek the advice of a health professional who can help guide your choice and stick with the plan.

Food & Fitness After 50: Citicoline for brain health?

In 2015 I wrote a post on a dietary supplement called citicoline. For the post click here.

HealthyBrainIn the post I wrote about learning of citicoline at a conference and was given a sample. My husband had been experiencing some trouble finding the right word when he was speaking so he wanted to try the supplement. From that day on he has continued to use the product. Although his report of improved brain health is anecdotal (one person’s subjective experience does not equal a fact) there is some research to support the positive effects of the supplement. He is such a disciple of citicoline that many of his family and friends now take it. But, should you?

I was interested in finding additional and more current, research since the 2015 post was written but didn’t find much. One reason might be that dietary supplement companies tend not to invest in rigorous experimental research trials because they are not required to do so to market a supplement. Unlike drugs, dietary supplements don’t have to prove they work to be sold; that’s why there are so many supplements readily available.

Citicholine
Chemical structure of citicoline

To begin, citicoline is a naturally occurring brain chemical. It is not found to any great extent in foods (there is some in organ meats) but when taken as a supplement it is broken down into choline (a B-vitamin) and a compound called cytidine which is then metabolized to uridine. That’s important because citicoline can’t cross the protective blood brain barrier but choline and uridine can. Once in the brain the compounds convert to citicoline, sometimes called CDP-choline. In turn, citicoline increases the brain chemical phosphtidylcholine that helps brain function and increases the number of chemical messengers in the brain.

When I first reviewed the literature the small number of studies that had been published cautiously suggested that supplemental citicoline could be an effective treatment for mild cognitive impairment but more research was needed to see if the effect was long term (most studies are short term…a few weeks to a few months) and if it could slow the progression to dementia.

A study published in 2012 was well-controlled: by a well-controlled study I mean the participants in the study were randomized to treatment and it was double-blind…neither the researchers nor the participants knew who was getting the citicoline or placebo. The researchers studied 60 healthy women, between the ages of 40 and 60, and showed that when given either 250 or 500 milligrams of citicoline both groups improved on tests to measure mental attention compared to the placebo group. However, this was another short-term study; just 28 days.

My quest to find more current research was unsuccessful so I turned to Natural Medicines Database for their review. The conclusion, which was last updated in November of 2019, was that citicoline is “possibly effective” for a decline in memory and thinking sills that occur with normal aging. Supplemental citicoline “seems to help memory loss in people aged 50 to 85 years.” The review noted there is insufficient evidence to say it prevents or reverses memory losses in those with Alzheimer’s Disease. There are minimal side effects, although some people report trouble sleeping, headache, or nausea.

The dose of citicoline ranges from 250 milligrams to 2000 milligrams a day, but the range of 250 to 500 milligrams is a usual dose used the research studies.

If you choose to try citicoline, it is always recommended to discuss with your health care provider. And, be sure to include all over-the-counter medications, including dietary supplements, when your doctor asks about medications you are taking.

CDP_suplrgI found over 150 products marketed that contain citicoline, some with fanciful names, liked Active Mind or Brain Wave that claim to “speed up your brain.” Many of those products also contain caffeine; the likely source of “speeding” the brain. If you get the blessing from your physician and want to try it, stick to one that just contains citicoline. Two reputable products are Cognizin (Kyowa Hakko) and Citicoline CDP choline (Jarrow). The Jarrow formula is the one that my husband takes.

As for me, my memory is good and I haven’t found a reason to try a supplement, but my husband believes it has helped him.

Food & Fitness After 50: Unlocking the MIND Diet

While there is no one best diet for those over the age of 50, in Food & Fitness After 50, we highlight four healthy eating plans that can work for just about everyone. And, it happens that these are the top four plans identified as the “Best Diets” by U.S. News & World Report in their 2019 review. The four plans are:

  • The Mediterranean Diet
  • The DASH Eating Plan
  • The Flexitarian Diet
  • The MIND Diet

minddietThe MIND diet stands for the official mouthful name of the Mediterranean-DASH Intervention for Neurodegenerative Delay. A much catchier title is the MIND diet because its premise is that diet can delay cognitive decline.  Researchers at Rush University Medical Center in Chicago studied over 900 older adults from retirement communities for 5 years; those who had the greatest adherence to the MIND diet suffered less cognitive decline than those who did not. This was an observational study, meaning that it shows association with diet and brain health, but it doesn’t prove it. So, the researchers are in the midst of conducting a longer, more rigorous study with adults in both Chicago and Boston. The results will be available in a couple of years.

However, the diet plan is healthy and while it can’t promise to prevent all cognitive decline with aging, it certainly can’t hurt as the plan is comprised of healthy foods that we should all be consuming.

Today, we feature the MIND diet by posing questions to registered dietitian, author, colleague, and friend, Maggie Moon. I met Maggie many moons ago at a CIA meeting…. Culinary Institute of America, not the spy agency, in her role as nutrition communications director for the Wonderful Company. The folks that bring us tasty, healthful foods, like pistachios, almonds, pomegranates and juice, and Halo mandarins. Maggie has written two books: The MIND Diet and the Telomere Diet Cookbook.

Chris and MaggieAs you can see from the photo of the two of us together at the annual meeting of the Academy of Nutrition and Dietetics conference, she is not in my age demographic, so my first question was obvious!

Question: You are a young woman…. how did you get interested in writing about food and nutrition to prevent cognitive decline which is something we think about as a part of aging?

Answer: I’ve been a registered dietitian for more than ten years and while I do still feel youthful, to answer your question, I think about when I was truly young. I grew up in a three-generation household with my parents and my grandmother. They were all immigrants from a war-weary and economically depressed South Korea in the late 1960s, so my immediate family is all I have. I am lucky to have a handful of siblings, but no big extended family. Because of this I feel extremely close to my parents and am ferociously driven to support their wellbeing. And because I was just as close to my grandmother, I’ve been aware of the importance of healthy aging from a young age.

I’ve always had an affinity for the elderly, probably because of my relationship with my grandmother. I love helping them and it is upsetting to my core when I hear about mistreatment of older adults. Truth is, I’m looking forward to being old lady! I’m in no rush, but it is something I think of fondly. I think of aging as a privilege.

This is a long answer to a simple question, but I guess it boils down to my writing what I care about. And I care about helping people thrive as they age and improving their health in longevity. It starts with my own parents, but then extends to my and my husband’s future, and finally to all humans that I can reach with my work, whether they’re worried about their own health or someone else’s.

 Question: Can you describe the MIND diet in your own words. What is it about the diet that would appeal to older adults and when is the best time to adopt the MIND principles? I can image some people in their 60s saying “it’s too late for me.”

Mind diet coverThe MIND diet was born from research led by Dr. Martha Clare Morris at Rush University in Chicago. Its foundation is a blend of two well-studied heart-healthy diets, but what makes it different is that it’s been optimized for brain health based on the available evidence for which specific foods support cognitive health, slow down decline, and reduce the risk of developing dementia. The two landmark studies that came out in late 2015 suggest that following the MIND diet keeps the brain 7.5 years cognitively younger and reduces the risk of Alzheimer’s by 53% compared to those who didn’t follow the principles of the diet.

It’s never too late, especially for someone in their 60s. Most of the research related to the MIND diet is with older adults, so it’s clearly relevant throughout older adulthood. The Alzheimer’s study was conducted with people ages 58-98 and the average age in the cognitive decline study was 81 years old.

That said, the results indicate that the longer someone followed the dietary principles the greater the benefit for brain health, suggesting that more years of healthy eating was more protective. Therefore, I think it’s important for people to eat for brain health at any age, but especially after age 40.

Question: What are the core principles of the diet? How did you develop the recipes for the book?

The core principles of the MIND diet includes ten healthy food groups that make up the foundation of the eating pattern. It also includes five food groups that should be limited.

The MIND diet includes whole grains, vegetables, olive oil, red wine (for those who drink alcohol), leafy greens, nuts, beans, berries, poultry, and seafood. From a culinary and cultural sensitivity perspective, I appreciate that the food groups are so broad that they can be adapted to many different heritage diets and preferences. The foods to limit include processed and red meat, solid fats from butter, margarine and cheese, fried food in general but especially from fast food, and added sugars from pastries and other sweets.

Here is a breakdown of recommended food groups to consume:

Foundation (these are minimums, except for red wine)

  • Whole grains – 3 times a day
  • Vegetables – daily
  • Olive oil – used as main fat
  • Red wine – a glass with a meal (only one; excess here is detrimental, and of course, if you don’t drink you won’t miss the benefits of the diet)
  • Leafy greens – six times/week
  • Nuts – 5 times/week
  • Beans – 4 times/week
  • Berries – 2 times/week
  • Poultry – 2 times/week
  • Seafood – 1 time/week

Limit

  • Processed and red meat – less than 4 times/week (e.g. no more than 3 times/week)
  • Butter/margarine – less than 1 tbsp/day (e.g. no more than 1-2 tsp/day)
  • Cheese – less than 1 time/week (e.g. once every two weeks)
  • Fried food – less than 1 time/week (e.g. once every two weeks)
  • Sweets – less than 5 times/week (e.g. no more than 4 times/week)

The recipes for the book were developed by me and other culinary dietitians. For the guest recipes, I collaborated with trusted colleagues. I provided the recipe parameters and then reviewed submissions to ensure they fit the guidelines and added a good variety of options before selecting them for my book.

Question: Let’s describe your newest book about telomere health….fill us in on how this ties into the MIND diet.

telomere-book-cover-on-amazonMy newest book, The Telomere Diet & Cookbook, came out in fall of 2019. It’s about genetic aging on a cellular level, and how what we eat can slow or accelerate biological aging. Telomeres are protective endcaps to our chromosomes, and they prematurely dwindle when exposed to inflammatory diets, environmental toxins, and poor sleep, to name a few. They protect the DNA in our chromosomes like shoelace tips protect shoelaces from unraveling and growing dysfunctional. Telomere length is a widely-accepted gauge for biological aging in research.

Telomere health is ultimately tied back to fighting inflammation and oxidative stress, which are also systemic issues the MIND diet attacks and improves. Both books are about healthy aging for all. In both books, the evidence-based perspective is that the more years spent eating healthfully the better. That sounds like common sense, and to some degree it is, but it actually signals a shift in thinking about aging: in this paradigm, aging is a continuum that begins at birth, not just once we hit a certain birthday. This is why two 50-year old people can be in completely different stages of biological aging while at the same chronological age – one vibrant, active and thriving; the other sedentary, sluggish and beleaguered with chronic health conditions. Of course, genetics, socio-economic factors, and lifestyle all play a part, but what we eat is something under our control.

Question: What the 3 key takeaways that you want people to know about cognitive health as we age?

  1. It’s never too late to start to eat healthfully.
  2. The earlier you start the better.
  3. Prevention through a healthy diet and lifestyle, not waiting for a miracle medication, is currently the best defense against age-related cognitive decline.
