Broccoli contains certain molecules that help to protect the lining of the small intestine of test animals, thereby preventing the development of disease, according to a recent study by researchers at Pennsylvania State University.

Broccoli is full of vitamins C, A, and K and is rich in fiber and potassium. This green vegetable can also help lower high blood pressure and is known to decrease the risk of cancer.

“We all know that broccoli is good for us, but why? What happens in the body when we eat broccoli?” Gary Perdew, one of the authors of the study, said in a Penn State article.
