Preliminary research suggests that diets that include omega-3 fats may protect against the development of cancer, reduce inflammation in the body, help prevent muscle loss associated with cancer treatment, and may increase the potency of certain chemotherapy drugs.
Omega-3s are found in a variety of foods and contain different levels of ALA, DHA, or EPA. The metabolically active forms, DHA and EPA, are the most potent anti-inflammatory substances. ALA must first be converted to DHA and EPA before it can help reduce inflammation.
Fatty fish, such as the salmon in this recipe (sardines, mackerel, swordfish, herring and tuna steaks fall in the same category), are good sources of omega-3 fats. These types of fish are rich sources of the more metabolically active EPA and DHA, which don't need to be converted from ALA to fight inflammation.
