The OmegaCheck test can help measure the balance of fats in your diet. omega-3 and omega-6 fatty acids are two of the most important types of polyunsaturated facts. The most important omega-3s are commonly called EPA and DHA. Omega-3s help brain function, including memory, and normal growth and development. They also can reduce inflammation. Our bodies don’t make enough omega-3s, so we must get them from the foods we eat, such as oily fish and plant oils. The most common form of omega-6s is called arachidonic acid, or AA. You get most of the omega-6s from animal foods in your diet, such as meat and eggs. This test may be performed on individuals with hypercholesterolemia, hypertriglyceridemia, hypertension, and/or those at high metabolic or cardiovascular risk.
