Omega-3 fatty acids are healthy, polyunsaturated fats that are found mainly in fatty fish, soybeans, and some nuts and seeds. Omega-3s are essential for normal physiological functions and, like other fats, can help satiate your appetite and stabilize blood-sugar levels. They can also reduce heart disease risk by decreasing overall inflammation, lowering triglycerides, and much more.
Omega-3s play a big role in heart health. We don’t yet know exactly why fish oil, which is rich in omega-3s, is so great for the heart, but it may be because it helps reduce inflammation and high blood pressure, decreases triglycerides, raises good HDL cholesterol, and makes blood thinner and less sticky so it’s less likely to clot — all major risk factors for heart disease. Because omega-3s help reduce inflammation, they are also the healthiest fats for people with arthritis or other inflammatory diseases and they help reduce the frequency, duration, and severity of migraine headaches.
