Long associated with overall heart health including helping your body maintain healthy cholesterol and triglyceride levels, Omega-3 fatty acids have also been found to lower blood pressure.
A new research study in Circulation, the journal of the American Heart Association, looked at the relationship between diet and blood pressure in over 4,000 men and women in Japan, China, Great Britain and the United States. The researchers found that those who ate diets rich in Omega-3 fatty acids had slightly lower blood pressure readings than those who ate diets with lesser amounts of the nutrient.
Diet and Blood Pressure
These fatty acids are not the first nutrient to be associated with lower blood pressure. Salt has long been considered important in blood pressure control, though some experts disagree with this widely accepted view. Other nutrition related factors in blood pressure control include maintaining a healthy weight and consuming a diet rich in fruits, vegetables and whole grains. Researchers noted that while all these factors have a small impact individually, together they can lead to a substantial improvement in blood pressure.
Omega-3 Fatty Acid Food Sources
Fatty varieties of fish like mackerel, lake trout, herring, sardines, albacore tuna and salmon are great sources of Omega-3 fatty acids. Other food sources like soybeans, canola, walnuts and flaxseed as well as oils from those seeds and nuts are also rich in Omega-3’s and contribute to overall heart health. However, research has found that the Omega-3 fatty acids in fish are especially beneficial.
