The Mediterranean diet emphasizes eating foods like fish, fruits,
vegetables, beans, high-fibre grains and breads, and olive oils. Meat, cheese,
and sweets are very limited. These recommended foods are rich with
monounsaturated fats, fibre, and omega-3 fatty acids.
Although this diet is similar to the
Therapeutic Lifestyle Changes (TLC) diet recommended
by the National Cholesterol Education Program (NCEP) of the U.S. National
Institutes of Health and the American Heart Association general dietary
guidelines, it is not exactly the same. On the Mediterranean diet, an average
of 35% of calories can come from fat, mainly from unsaturated oils, such as
fish oils, olive oil, and certain nut or seed oils (such as canola, soybean, or
flaxseed oil). These types of oils may have a protective effect on the heart.
Initial studies have shown that the Mediterranean diet may reduce the
rate of a second heart attack and death in people who adopt the diet following
a
heart attack.1 Further
research is needed, but current studies reinforce the importance of eating a
diet rich in fruits, vegetables, fish, and high-fibre breads and whole grains.
Furthermore, incorporating a moderate amount of fats from nuts, seeds, and
foods high in linolenic acid (such as walnuts, flaxseeds, flaxseed oil, and
canola oil) may also help prevent heart disease.2
