White Bread Is Harmful, But Not Because Of Carbs

Although some people believe that carbohydrates prompt heart disease, this isn't the case. Carb-heavy foods, such as bread, only cause harm if they have sugar. White bread is all simple sugars, which can cause blood sugar spikes. In 2010, researchers found that eating white bread frequently doubles a woman's risk of heart disease.

An associate professor of nutritional medicine, Marie-Pierre St-Onge, says that white bread "looks pretty much like plain sugar, really, just simple carbohydrates." You can eat whole-grain bread; the American Heart Association encourages it! But avoid white bread for the sake of your heart.
