AHA RecommendationsThe AHA recommends that all adults eat fish (particularly fatty fish) at least two times a week.3 Fish is a good source of protein and is low in saturated fat. Fish, especially oily species like mackerel, lake trout, herring, sardines,albacore tuna, and salmon, provide significant amounts of the two kinds of omega-3 fatty acids shown to be cardioprotective,EPA and DHA. The AHA also recommends eating plant-derived omega-3 fatty acids. Tofu and other forms of soybeans; walnuts and flaxseeds and their oils; and canola oil all contain ALA.For patients with documented CHD, the AHA recommends 1 g of EPA and DHA (combined) per day. This may be obtained from the consumption of oily fish or from omega-3 fatty acid capsules, although the decision to use the latter should be made in consultation with a physician. The amount of EPA and DHA in fish and fish oil is presented in the recent AHA Scientific Advisory on omega-3 fatty acidsand CVD.2 An EPA DHA supplement may be useful in patients with hypertriglyceridemia. Two to four grams of EPA DHA per day can lower triglyceride 20% to 40%. Patients taking more than three grams of these fatty acids from supplements should do so only under a physician’s care.Very high (“Eskimo”) intakes could cause excessive bleeding in some people.
