You don’t have to run out and hug a tree or play hackie sack while barefoot in the park to celebrate Earth Month. Instead, Earth Day and Month were designed to designed to inspire awareness for our environment. What’s in it for you? A polluted environment leads to pollution in our food and water supply that ends up on our plates and in our bodies. And therefore, a healthier earth means a healthier you. You can do your part by recycling, disposing of hazardous wastes properly (so they don’t end up in the water you drink or on the plants you eat) and changing your diet by incorporating foods that are not only good for you but also use fewer environmental resources to produce and/or are produced in an earth-friendly manner. On a recent segment on WBAL NBC Baltimore MD, I shared the top 3 steps you can take right now to help protect the environment and improve your diet at the same time:

1) Choose green seafood – seafood that’s both good for you and good for the ocean.  The DC-based Environmental Working Group has a guide to seafood that is high in omega-3 fats and low in methylmercury. This is especially important for pregnant women and young children. Growing fetuses are exposed to methylmercury in the womb when their mom eats fish and shellfish that contain methylmercury. Methylmercury can harm a baby’s growing brain and nervous system. Recent government data suggests an estimated 1.4 million women of reproductive age have blood mercury concentrations that may increase the risk of learning disabilities in their unborn children. Exposure to mercury is harmful to all people and may have toxic effects on the nervous, digestive and immune systems, and on lungs, kidneys, skin and eyes. EWG top choices for lower mercury omega-3 rich seafood: wild salmon, sardines, Atlantic mackerel, mussels and rainbow trout.

2 ) Go Meatless. Now, I’m not suggesting everyone go completely meatless (because animal based sources of protein are typically better for building and maintaining muscle) but, adding more plant based proteins or going completely meatless for 1 day a week has the environmental impact of taking your car off the road for 320 miles, according to the Environmental Working Group. How does this help your body? Plant based sources of protein are typically lower in calories yet they are packed with good nutrition including vitamins, minerals, and dietary fiber. How can you get enough protein – choose soy, beans, lentils and nuts. I often mix animal-based proteins with plant-based proteins at meals.

3) Cook with canned foods. Americans throw away approximately 15 to 20 percent of the fresh fruits and vegetables they purchase every year. Stock up on canned foods because they help reduce food waste, saving us time and money, and reducing our impact on the environment. Canned food portion sizes are just right for both individuals and families, and most recipes are designed around these sizes. Plus, metal cans are endlessly recyclable and in fact, are the most recycled containers in America today, keeping metal out of landfills and saving significant energy.

If you’re among the 60% of Americans with elevated blood pressure I’m sure you’ve heard your doctors say these things: “lower your sodium intake,” “increase your physical activity,” and “decrease your alcohol consumption.” While these are all great recommendations, new research has shows there is an alternative treatment that may be even better at lowering blood pressure: the omega-3 fatty acids eicosapentaenoic acid (EPA) and decosahexaenoic acid (DHA)4.

Omega-3 fatty acids are an essential (the human body can’t make them) polyunsaturated fat. There are three main types of omega-3s, EPA, DHA and alpha linolenic acid (ALA). EPA and DHA are found in cold-water fish, fish oil, and algae and are crucial for brain development, reducing inflammation, protecting structural cell integrity, and they may help decrease muscle soreness in athletes1.

In March of 2014, the American Journal of Hypertension released a comprehensive meta analysis (a statistical method for combining the results of several studies) that examined 70 randomized controlled trials studying the effect EPA and DHA on blood pressure (BP). Participants were adults with normal BP and adults with high blood pressure who were not taking BP lowering medications. Subjects were given EPA and DHA omega-3s in the form of seafood, fortified foods, or dietary supplements. The results of the study showed a decrease in both systolic and diastolic BP in all adults. The most significant effects were found in those with existing high BP. There was an average 4.51 mm Hg decrease in systolic blood pressure (SBP) and diastolic blood pressure (DBP) was reduced by an average 3.05 mm Hg4.

The analysis also compared common lifestyle recommendations and their effects on BP to EPA and DHA omega-3 fatty acids effects on BP. The findings were astonishing. When looking at SBP (the top number – this reflects the pressure in your arteries when your heart beats), consumption of EPA and DHA omega-3 had an average decrease of 4.51 mm Hg, while reduced dietary sodium had an average reduction of 3.6 mm Hg, and decreased alcohol consumption had an average 3.8 mm Hg decrease. The only lifestyle recommendation shown to have a greater decrease in SBP was increased physical activity, which lowered SBP by 4.6 mmHg.

Still not sold on the benefits of consuming omega-3? There’s more! Over the past two decades, some research has linked the consumption of omega-3 fish oils to a reduced risk of cardiovascular disease. Heart disease is the leading cause of death in the U.S. killing about 600,000 Americans each year (that’s 1 in every 4 deaths)2. As previously discussed, omega-3s reduce BP levels (a major risk factor for heart disease) and lower triglyceride levels. A study published in the Journal of American Medical Association concluded consumption of omega-3 fatty acids creates a significant cardioprotective effect in non-hypertensive individuals3.

How do I get my omega-3 fatty acids?

  • The American Heart Association recommends eating fish at least twice a week to increase omega-3 dietary intake
  • Fatty fish such as mackerel, lake trout, sardines, herring, albacore tuna, and salmon are all great sources of omega 3 fatty acids
  • Eating walnuts, flax seeds, soy beans, kidney beans, and tofu are other great ways to increase your omega 3 consumption. These provide Alpha- Linoleic Acid (ALA) form of omega 3s.
  • When looking for omega 3 supplements choose nordic naturals or any supplement that is USP certified. Costco’s Kirkland brand is a great option!
