Women who eat a lot of foods rich in refined carbohydrate like white bread, pizza and rice are twice as likely to develop heart disease as women who eat few of those foods, according to a recent study from Italy. The increased risk seems to be associated with carbs that are quickly absorbed into the bloodstream rather than carbohydrates on the whole, say the researchers. Heart-Smart Swap: Instead, choose unrefined (and therefore more slowly digested) whole-grain alternatives. Brown or wild rice, 100 percent whole-wheat bread and whole-wheat pizza crust are all good options.

The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest.
In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart.
