Thousands of people every year pay thousands of dollars for state-of-the-art testing to learn their risk for heart disease. However, experts say that fresh vegetables and fruits and a health club membership may be better buys than any lab test. People who ate a diet low in fat and cholesterol and rich in healthy plant foods, who don't smoke, who exercise regularly, and keep their weight and blood pressure in the normal range are less likely to have a heart attack than those who don't, despite any predisposition or genetic tendency toward heart disease. - Harvard Health Letter
