The heart and the brain connection: is there a role for dietary fats?

The quality and the quantity of dietary fats play an important role in the
onset of heart disease. Several studies have shown that the intake of omega (n-3) polyunsaturated fatty acids (PUFA) is beneficial to protect against heart
disease. N-3 PUFA are also vital for the proper development and function of
the brain. We have recently made an observation that a diet high in n-3 PUFA
lowers plasma lipid levels, as well as increase the expression of genes
involved in brain function. Our findings suggest a common pathway that
regulates the function of the heart and the brain.
