Background

Broccoli (Brassica oleracea) is a common vegetable eaten as food. Other varieties of Brassica oleracea include kale, Brussels sprouts, and cauliflower.

Chemicals in broccoli might help prevent cancer and have antioxidant effects. Also, when broccoli is eaten with a starch, it slows down how quickly sugar from the starch goes into the blood, which might benefit people with diabetes.

People use broccoli for high cholesterol, fibromyalgia, preventing certain cancers, and many other purposes, but there is no good scientific evidence to support most of these uses.

Don't confuse broccoli with broccoli sprout, or with chemicals found in broccoli, including ascorbigen and indole-3-carbinol. These are not the same.
