Danish researchers found in general, people who reported eating more fatty acids were no less likely over time to develop ischemic heart disease than people who consumed less of the nutrients.
However, women who ate the most Omega 3's did appear to benefit. They had nearly 40-percent lower risk of developing heart disease.
Scientists say the basic advice for consumers is to eat a diet high in fruits and vegetables and low in red meat. Even if fish oil proves not to protect against heart disease, it could still be good because fish may be displacing a food that's high in saturated fat.
