According to Dr. Steven Nissen, chair of the cardiology department of the Cleveland Clinic, today's 75-year-old can live to be 90 or 95. But there are some things to do and not do to stay healthy, especially heart healthy. Here is his #1 thing to stay away from: Fad Diets! He says there are many diet books out there and all are mostly contradictory. "One will say eat no fat. The next one will say eat no carbs. They're all wrong. None of these diets is healthy or appropriate for cardiac health." That is a quote from Dr. Nissen. His #2 thing to stay away from is dietary supplements. He stated, "There's no way to know what's in them (they are largely unregulated).
He says heart health is determined by the quantity and types of foods one eats. He cited a recent study in the New England Journal of Medicine that looked at a low-fat diet versus a Mediterranean-style diet. Those who consumed a diet rich in olive oil and nuts (both have fat content but they are good fats) had a much lower risk for heart disease. That would be a Mediterranean-style diet.
