What Are Antioxidants?
Antioxidants are molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged. Although there are several enzyme systems within the body that scavenge free radicals, the principle micronutrient antioxidants are vitamin E, beta-carotene, and vitamin C.
Selenium, a trace metal that is required for proper function of one of the body’s antioxidant enzyme systems, is sometimes included in this category. The body cannot manufacture these micronutrients so they must be supplied in the diet.
Why Eat Fish Weekly?
Best choices are oily fish rich in healthy omega-3 fatty acids, such as herring, sardines, salmon, lake trout, mackerel and albacore tuna. But forgo fish oil capsules unless you have been diagnosed with heart disease and can’t eat at least two meals of fish per week. People with high triglyceride levels who are under the care of a physician may benefit from omega-3 fatty acids in capsules. The U.S. guidelines also recommend two servings of fish per week, but they doesn’t address fish oil capsules in the same detail as AHA.
