The two types of Omega 3s measured in the study boost brain health, but researchers don't know how. According to some research, the family of fats may have anti-Inflammatory benefits. Satizabel said that scientists don't understand everything yet, but by increasing consumption of Omega 3s, you are protecting your brain.

Omega 3 fats are important in the production of hormones that regulate inflammation and blood clotting as well as other bodily processes. The human body can't make its own fats on it's own, so it gets the essential vitamins and minerals from foods, like fish, vegetable oils, nuts and leafy vegetables. The fats have been shown to have a number of health benefits, including a reduced risk of cardiovascular disease. The fats may boost brain health in older adults, but less research has been done in younger people.
