The Convincing Benefits of Omega-3 Fatty Acids or Fish Oils in the diet

In 2012, an article in the Economist magazine postulated that marine mammals such as whales and dolphins evolved higher intelligence than land mammals due to their diet of fish. Many research studies support the belief that high levels of omega-3 fatty acids found in fish oils is protective to the aging of the human brain and heart. The Heart Association cites evidence that Omega-3 fatty acids decrease the incidence of cardiac arrhythmias such as atrial fibrillation, lowers the level of serum triglycerides and slightly lowers blood pressure. Because omega-3 fatty acid is a precursor of serotonin, a neurotransmitter in the brain related to mood, many psychiatrists also recommend omega-3 fatty acids to their patients.

The typical American diet is deficient in Omega-3 fish oil and few Americans eat 2-5 servings of fish per week to make up this deficit. For this reason, most physicians, especially cardiologists, recommend that patients consume a dietary supplement of 1000 milligrams of omega-3 fatty acids per day. These gel caps are quite affordable and do not require a prescription.

As a physician, I have spoken to a number of nutrition specialists, and most recommend taking a daily dose of Omega-3 fish oil. Based on their advice, I also take 100 mg of the antioxidant CoQ10 and Vitamin D. My experience suggests that a Vitamin D supplement has an effect on the immune system and is protective against colds and respiratory infections.
