Carbohydrates and your health

Despite their bad rap, carbohydrates are vital to your health for a number of reasons.

Providing energy

Carbohydrates are your body's main fuel source. During digestion, sugars and starches are broken down into simple sugars. They're then absorbed into your bloodstream, where they're known as blood sugar (blood glucose).

From there, glucose enters your body's cells with the help of insulin. Glucose is used by your body for energy, and fuels all of your activities — whether it's going for a jog or simply breathing. Extra glucose is stored in your liver, muscles and other cells for later use, or is converted to fat.

Protecting against disease

Some evidence suggests that whole grains and dietary fiber from whole foods help reduce your risk of cardiovascular diseases. Fiber may also protect against obesity and type 2 diabetes. Fiber is also essential for optimal digestive health.

Controlling weight

Evidence shows that eating plenty of fruit, vegetables and whole grains can help you control your weight. Their bulk and fiber content aids weight control by helping you feel full on fewer calories. Contrary to what low-carb diets claim, very few studies show that a diet rich in healthy carbohydrates leads to weight gain or obesity.
