Doctors say eating a "Western diet" heavy on meat, fried and salty foods accounts for a third of heart attacks worldwide.
Medical researchers compared an American diet to an Oriental diet and a more "prudent" regimen consisting of fruits and vegetables.
People who ate the Western diet had a 35 percent greater risk of heart attacks.
Those who ate more of an Asian diet consisting of tofu and soy had an average risk.
People eating vegetables and fruit had a 30 percent lower risk of heart attacks.
