Food & Fitness After 50: Fish Oil Supplements

We’ve been exploring the benefits of seafood in the diet (for the previous posts click here and here). Today let’s answer your questions on fish oil supplements.

As a quick reminder, health organizations like the American Heart Association recommend at least 2 servings (a serving is equal to 3.5-ounces) of fatty fish twice each week to get the recommended 250-500 milligrams of omega-3 fatty acids of EPA and DHA (sometimes referred to simply as fish oils). But there is nothing simple about sorting through the many fish oil supplements on the market for those who don’t eat enough fatty fish. Add to that, trying to wade through the sea of health claims and understanding the label is even trickier. I checked in with Senya Joerss, Technical Manager for Trident Seafoods Corporation to ask about fish oil and omega-3 supplements.

While I don’t want this to turn into an organic chemistry lesson, this infographic can help explain the different types of omega-3-fats. While we tend to lump them together under the umbrella of omega-3s, what we are really after are the EPA and DHA, the two omega-3s that have been extensively studied to promote heart, brain, and eye health.

That leads to the first question on the various formulations on the market.

Question: Is salmon oil a better choice for a supplement than other omega-3s on the market?

Salmon oil contains a good amount of omega-3s but some fish contain more (sardines and mackerel for example). But, the omega-3 content of fish is dependent on what the fish eat. Salmon is one of the fattier fishes and therefore salmon oil is a good choice for a supplement due to its omega-3 content. As a consumer, that means you can take fewer capsules. Also, salmon oil is a natural form of the fats meaning better absorption, so it gets in to the blood stream more readily. Joerss responded this way, “Trident’s product, Pure Alaska Omega Wild Alaskan Salmon Oil delivers the same whole fat omega nutrition as eating two portions of cooked wild salmon per week; it’s the closest supplement option when you cannot eat fish for dinner.” And while the health benefits of EPA and DHA are what we are after, Joerss states that “fatty fish, like salmon, contain many other fatty acids and omega fats (examples: Omega-7, Omega-9, Omega-11 fatty acids) that are not as well researched as EPA and DHA fatty acids, but there is a plethora of evidence to support overall health for populations eating fatty fish regularly.” She believes there is a synergistic effect in consuming multiple fats together to provide balance. So, while eating fatty fish is the best way to get the health benefits, salmon oil is the next best thing.

Question: How do you read a nutrition label for fish oil. I find it confusing. For example, the front of the bottle says 1000 milligrams yet the supplement facts panel on the back of the bottle says 2 softgels contain 600 milligrams of omega-3s.

Joerss understands the confusion and says “it is challenging for the consumers to interpret fish oil labels because they all look slightly different.” For Trident’s product, what you are taking is “Salmon Oil” so that is the name of the product and the largest font callout on the front of the label. The 1,000 mg is the amount of Salmon Oil you get with each softgel. This is typically the way “Fish Oils” are marketed especially if the oil is not refined because fish oil contains more than omega-3 fatty acids. (Another example would be “Cod Liver Oil” softgel products, they list the amount of cod liver oil consumed per unit or per softgel on the front, so you know how much cod liver oil each unit/softgel delivers).

PAO_Salmon-Oil_Costco.com_v7FAThe suggested serving size for the Pure Alaska Omega Wild Salmon Oil is 2 softgels which is 2,000 mg (2 grams) of salmon oil per serving. The salmon oil omega-3 content, other fatty acid contents, vitamin content (A & D), and other fat-soluble compounds remain present in the same portions and amounts you would find in the lipid (fatty) portion of wild salmon.” Which is why the amount of EPA + DHA don’t add up to 1000 milligrams.

However, Joerss adds that “while there are some products that do not list EPA and DHA exclusively on the label all fish oils should include a total omega-3 value.” She explains that some products, like “whole omega” fish oil calls out only total omega-3s because it is a natural product.

Watch out for the claim that omega-3 supplements contain a certain percent of the Daily Value or DV.   This is a meaningless claim because there is no Daily Value set by the USDA or FDA for fish oils. You will find a DV for nutrients like vitamin D, but not for fish oil.

Question: What is astaxanthin and is that unique in fish oil products?

Astaxanthin is an antioxidant or carotenoid found in bacteria and algae. It gives the pink color to shrimp and salmon and other crustaceans. Joerss explains that “astaxanthin is present in wild fish that eat and feed freely on algae and other fish in nature. Salmon oil that is cold-pressed, similar to extra-virgin olive oil, uses an extraction process that preserves the astaxanthin that is present in the wild salmon – so that is unique compared to most other fish oils which remove this as part of the refining/concentration process.” However, Joerss points out that astaxanthin in Trident’s salmon is oil is small when compared to products that add this carotenoid to their fish oil supplement.

Question: Is there a fish oil for vegans?

Algal oil is a good option for vegans. Algae is where fish get their EPA and DHA so oil made from algae can supply omega-3s to plant-based eaters. Algal oil is more costly than other fish oils but can meet the needs of vegans.

Question: Many people complain of a fishy aftertaste when taking fish oil…any tips for reducing the after taste (i.e., taking with meals, taking at a certain time of day, refrigerating the capsules?)

Some people do complain with the “fish burb” or aftertaste, but Joerss recommends taking the supplement at the beginning of a meal and a substantial meal, like lunch or dinner would be best. “Some people report taking it with orange juice, but I do not think oil and seafood typically pair nicely together with OJ!” She adds that “we do not recommend freezing or refrigerating the capsules because that will prolong the rupture time of the softgel. If the softgel does not rupture soon after being swallowed that is less time for your body to absorb the nutrients within each softgel.

Food & Fitness After 50: Good Food for your Valentine

Tomorrow we think of affairs of the heart: flowers, cupid, and chocolate all come to mind. But, this year, treat your special someone to something really good for their heart and brain…seafood and fish. OK, not the most romantic or sexy of foods, but fish and seafood provide needed fats for healthy hearts and brains.

Fish and seafood contain high quality protein (here is an older post on protein for those over 50.)

But today we are focusing healthy fats. For that, fish can’t be beat. A quick look at the alphabet soup of healthy fats:

Fish oil pillsOmega-3s: These are the chemical class of healthy fats; if you want to impress your friends tell them the name omega-3s comes how the fat molecule is structured; the omega end of the chemical fat chain and the first double bond, 3 carbons in…hence, “omega-3s.”

EPA and DHA are 2 types of omega-3s that help to keep our blood vessels healthy (a healthy blood vessel dilates and contracts to control blood pressure and move blood throughout the body; a stiff blood vessel is not a healthy one), helps to lower a blood fat called triglycerides, and helps brains cells communicating (fat makes up a large part of our brain). DHA is especially important in brain health. Dr. Tom Brenna, of the Dell Pediatric Research Institute at the University of Texas at Austin puts it this way, “as calcium is to the bones, DHA is to the brain.”

ALA is another type of healthy omega-3 found in plant foods like walnuts, chia seeds, and flax. While we need this type of fat, too, only a small amount of it is converted to EPA and DHA, so it isn’t a substitute for fish, seafood, or fish oil supplements.

Health organizations recommend that we eat fish or seafood twice a week (4-ounce portions) to get the needed 250-500 milligrams of EPA and DHA. Not all fish is created equal when it comes to the healthy fats: fatty fish like salmon, trout, anchovies, mackerel, and sardines have the highest levels, with milder fish like cod, haddock, mahi mahi, and tilapia containing lower levels. However, don’t let that discourage your from eating tilapia or mahi mahi, but consider adding some sea bass or tuna in the mix to boost EPA and DHA intake. For great information on everything you want to know about fish…from omega-3 containing fish and seafood to choosing and preparing fish, check out the Seafood Nutrition Partnership.

A couple of other things to consider:
• Frozen or canned fish is not inferior; it is kind to your wallet and is a good way to eat fish if you can’t find fresh seafood in your local market. I use frozen fish to grill and blacken for tasty fish tacos and frozen shrimp for Pad Thai or a stir-fry.
• Grill it, broil it, bake it, steam it, or poach it to keep the omega-3s from losing their potency. The high heat of frying can break down the omega-3s, so save that cooking method for the occasional fish fry.
fish oil• If you just don’t like fish or have a family member who won’t touch it, consider fish oil supplements. Look at the nutrition facts panel to make sure you are getting EPA and DHA in the 250-500 milligram range. On this label you see value of a 1000 milligrams, but not all of that fish oil is EPA and DHA; you’ve got to look at the actual amount of EPA and DHA in the supplement.
• For vegetarians, consider an algae-based omega-3 supplement.
