The Mediterranean diet can reduce the risk of cardiovascular disease. But a study published Monday in the International Journal of Epidemiology found only people with higher incomes or more education, or a combination of the two, experience this benefit.
In addition to fish and poultry, the Mediterranean diet emphasizes eating plant-based foods, including vegetables, nuts, fruits and whole grains. The diet also recommends that you limit red meat, replace butter with olive oil, and exercise. Red wine in moderation is optional on the diet.
