Omega-3s: Three food label tips that might surprise you

omega-3Have you noticed that omega-3s seem to be added to all types of food such as eggs, oj, milk, cereal and yogurt? When you read the label it can be confusing. What is the source of the omega-3s and how much is in the product? Here’s what you need to know to be a label sleuth.

There are three types of omega-3 fats which include DHA, EPA and ALA. The majority of omega-3 research looks at the health benefits of DHA and EPA which are found in the highest amounts in fatty seafood such as tuna, salmon and sardines. The suggested intake for these two omega-3s combined is about 650 milligrams per day (DHA + EPA) but this amount varies significantly depending on health issues you may have such as heart disease. DHA is also found in marine algae and this source of DHA is often added to food products.

ALA is found in plant sources only such as walnuts, pumpkin seeds, flaxseeds, kale and small amounts in soybean and canola oil. ALA must convert in the body to EPA and DHA and the conversion rate is only about 10%. This means that if you have a serving of a food which contains 100 milligrams of omega-3s from an ALA plant source, after the 10% conversion you end up with 10 milligrams of EPA and DHA…the form that the body uses. You can see it takes a lot more ALA.

If you are buying omega-3 fortified foods, meaning that omega-3s have been added to the product, they are likely in the form of ALA or maybe marine algae (DHA) or a combo of both such as flax and marine algae. So, if the product you are about to buy says it contains 300 milligrams of omega-3s per serving, flip it around and read the ingredient label.

What is the source of omega-3s? If it’s flax, walnuts or any of the other plant food items just mentioned, remember that you are only going to derive about 10% as usable DHA and EPA or 30 milligrams. If a product doesn’t tell you which omega-3s are added, assume it to be a plant ALA source.

blue-ceanIf you’re a fish eater, two servings a week is an easy way to get DHA & EPA. In these lean economic times, fish doesn’t have to blow your budget either. Canned salmon, light tuna and sardines all work just fine. You might be saying to me…what about the mercury in fish? The PCBs? Try this tech tip courtesy of blueocean.org. You can send a text and make sure the fish you purchase is eco-friendly and without a health advisory. Send a text to 30644 with the message FISH followed by the name of the fish you want to buy…for example, FISH SCALLOPS or FISH SALMON.

I sent a text for FISH SALMON and received two texts within a few seconds. The first text had a red flag saying that farmed salmon has significant environmental concerns with a health advisory for potentials PCBs and pesticides. The second text with a green flag indicating a better choice said that wild Alaska salmon has very few environmental concerns. The Blue Ocean Institute tracks 90+ fish species and regularly updates their database. You can check out their website at http://www.blueocean.org.

Currently, Sheila is the owner of a medical nutrition private practice, Integrative Nutrition Solutions, in Palm Harbor, Florida.

We talk about autoimmune diseases and why they are more prevalent in women.  Did you know that stress can trigger an autoimmune disease? Sheila shares key foods to include in your diet such as omega-3 rich fish if you have an autoimmune disease. You don’t want to miss it.

Chocolate for your Valentine

If you read my blog regularly, you know I’m a chocolate lover. I have some chocolate most every day and dark chocolate is my favorite. Dark chocolate with cherries, hazelnuts, spices…I love it all. If you feel the same way or plan to give chocolate to someone special and whose heart you care about this Valentine’s Day, then you’ll want to read this new research.

Dark chocolate has a sensual mouth feel and is loaded with phytonutrients called flavonoids. Guess what? These flavonoids may have anti-inflammatory effects in the body that can lower the CRP. What’s CRP you might be saying? CRP stands for C-reactive protein found in the blood that is tied to inflammation and heart disease. Recent studies out of Johns Hopkins found that eating dark flavonoid rich chocolate lowered the CRP level in women by 23% and improved lipid profiles in both men and women.

I think more research will be conducted to determine if it’s the flavonoids or other compounds in chocolate which provide this cardiovascular benefit. Remember, portion control is still key due to the calories and fat in good chocolate but at least we can kick the guilt to the curb.

Four Healthy White Foods

Filed under: Healthy Food — admin @ 2:53 pm

mushroomsWhen it comes to your diet, what one improvement could you make that is talked about frequently? Eat more fruits and vegetables! This mantra is now engrained in nutrition education because of the health benefits from consuming fruits and vegetables. Look for intense colors or the colors of the rainbow…right? Then you know that the fruit or vegetable is jam packed with nutrition. The bright green flesh of a kiwi or the orange-red pigment of a blood orange comes from the naturally occurring phytochemicals also called phytonutrients that are found in these items. Remember phytochemicals? Phyto means plant so these are naturally occurring chemicals or nutrients found in fruits and vegetables that have a beneficial effect on your body beyond basic nutrition. Research continues to link the potential for prevention of numerous health issues to eating more fruits and vegetables as part of your daily diet.

What about white vegetables and white foods? Since they’re bland in color, does this mean they’re not good for you? Oh contraire! Let’s talk about four healthy white foods that just might surprise you.

  1. Mushrooms: sunbathing and ending up with beneficial vitamin D. Scientists from the Agricultural Research Service (part of the USDA) have been working with a California mushroom grower to expose ordinary mushrooms to UV-B light as they grow. These sun bathing mushrooms provide 100% of the recommended amount of vitamin D in a three ounce serving. Vitamin D is a hard vitamin to obtain enough of without a supplement.  UV-B rays are the same rays that our bodies use to make vitamin D naturally from sunlight. They will be marketed under the name Sun Bella.
    Current researchers from Tufts University found in rat studies that eating white button mushrooms (most of what we eat in the US) enhanced natural killer cell activity, a part of the immune system that fights against tumors and viruses. Now the research needs to be replicated in humans.
  1. Leeks: look like scallions on steroids. The leek is a member of the onion family. Leeks contain an antioxidant called quercetin that is thought to help fight cancer. Don’t forget about onions, scallions, garlic and chives. All contain those smelly compounds being studied for their role to slow or stop tumor growth.
  2. White Beans: the trendy bean is a good source of protein and fiber plus antioxidants along with iron, copper, potassium and phosphorous. Beans are more popular than ever right now because they’re a good value and you can do a lot with them. White bean soup is easy to make or even a hearty bowl of white beans with your favorite bread. I use white beans in broccoli soup to thicken it and add protein.
  3. Potatoes: white potatoes were kicked to the curb during the low carb craze.  But potatoes have a number of redeeming qualities including vitamin C and if you eat the skin both fiber and chlorogenic acid. A phytochemical that may be beneficial against cancer causing agents known as carcinogens which are found in cured meats, chlorogenic acid is mainly in the potato skin.
