Eat more food rich in omega-3 essential fatty acids (EFAs), as they manufacture substances within the body that regulate critical functions, including arterial muscle tone, transport of oxygen in the blood and inflammatory response. Foods that feature EFAs such as omega-3 include cold-water oily fish like herring, mackerel and salmon, as well as flax seed oil and evening primrose oil, pumpkin seeds and cauliflower.
