Eating too much omega-6 fat—especially from vegetable oils and meat from grain-fed animals—might increase body-wide inflammation, which could lead to long-term health problems like heart disease or diabetes.

Eating fish or fish oil rich in EPA and DHA omega-3s may help make dangerous fatty buildups in your arteries more stable and less likely to burst, by calming down harmful inflammation and helping your blood vessels relax better.

Diets with a high ratio of omega-6 to omega-3 fatty acids are linked to higher levels of inflammation and greater body fat in humans, while diets with a balanced ratio are linked to lower inflammation and reduced obesity risk.

Taking omega-3 supplements may help slow down the buildup of fatty plaques in your arteries by lowering bad fats in your blood, preventing clots, and calming down inflammation in your blood vessels.

Taking omega-3 supplements may help lower inflammation in your body, which you can see through blood tests that measure markers like CRP and IL-6.
