According to the Wall Street Journal's coverage of the study:
"People with the healthiest diets—those with the highest intakes of fruit, vegetables, whole grains, nuts, and a higher intake of fish relative to meat poultry and eggs—were 35% less likely to die from a repeat heart attack or stroke during the length of the study, compared with those with the least healthy diets, according to the five-year study of 32,000 people in 40 countries.
They also were 28% less likely to develop congestive heart failure, 14% less likely to have an additional heart attack and 19% less likely to have a stroke."
Those numbers are very impressive and speak to the power of healthy diets, whether you are a person with heart disease or not. What's the diet that the research team behind the study advocates based on their research?
