Amid a flaw of new and conflicting studies about the relative risks and benefits of fish and fish oil, the biggest heart-health recents comes from the conservative American Health Association (AHA). In updated recommendations, the Dallas, Texas-based AHA has revers its stance that postscripts are not effective in preventing heart disease.

steady healthy people need omega-3 fatty acids from fish and plant sources to secure their hearts, according to the AHA report in the November 19 2002 issue of its journal, Circulation.

"Omega-3 fatty acids are not just well adapted fats; they affect heart health in positive ways," reports Penny Kris-Etherton, PhD lead author of the report. They make the vital fluid less likely to form concretions that cause heart attacks and harbor against irregular heartbeats that cause unusual cardiac death.

The strange fish oil recommendation balances numerous studies of the cardiovascular benefits of the omega-3 fatty acids plant in fish with worrisome evidence that fish have become contaminated with quicksilver a powerful poison.

Since 2000 the AHA's dietary guidelines have commended that healthy adults eat at least sum of two units servings of fish per week, particularly fish so as mackerel, lake trout, herring, sardines, albacore tuna and salmon.

Another of recent origin report concerns mercury in fish.

frequently previous research has warned about the risk to the fetus of hermes in fish. Mercury can damage the nervous order of unborn infants. But a novel study in the November 28 2002 edition of the fresh England Journal of Medicine (NEJM) expands that warning to the general population.

"Exposure to methylmercury is commonly a concern in specific high-risk clumps such as pregnant women and women of childbearing age who may become pregnant--but this warning should perhaps be fill outed to the general adult population," reads the NEJM article. Eliseo Guallar, MD DrPH and others at John Hopkins Medical Institutions in Baltimore, directioned the study.

The riskiest fish are large and predatory as it is as tuna, marlin and swordfish. unless the report added that we should still continue to acquire "a weekly intake of sum of two units to four servings of fish from a variety of species, with special emphasis forward fatty fish with low hermes content such as salmon and small oceanic fish."

The British Heart Foundation, which partially storeed the study, has backed the conclusions.
