A recently completed NIH study might have you soon adding more fish to your menu. According to researchers, the more fatty fish you have in your diet, the more your heart is protected. In fact, if you eat as much fish as our friends in Japan, you may even be able to ward off heart disease.

It’s the omega-3s that are found in fish oil that are the key, of course. Fish oil naturally reduces inflammation and helps keep plaque from forming in your arteries.

The researchers partnered with Japanese scientists to follow a mix of nearly 300 American and Japanese men for five years. They tracked a variety of heart-disease-related factors, including cholesterol levels, cigarette smoking, drinking, and diabetes and blood pressure status. (Even genetics were considered.)

After taking into account all the heart-related factors, the American men, shockingly, had three times more artery calcification than their Japanese counterparts! What was the difference between the two groups? It turns out that the Japanese men had 100% higher levels of omega 3s in their blood streams.

In Japan an average person eats about 100 grams of fish every single day—that equals about one and half servings. Even fish fans might find that much fish difficult to swallow. That’s where an omega 3 fish oil supplement can help fill the gap. Just be sure the one you choose comes from a source you trust.
