Bell peppers
Not only are bell peppers high in vitamin C, but they contain phytochemicals that may block the growth of cancer cells. “The number one thing is to eat fruits and vegetables and get a variety of the colors in there,” said Rachel Johanek, RD, a dietitian with the Georgia Cancer Center at Augusta University. “Each of them has a different phytochemical compound that helps prevent damaged cells and protects good cells. I tell people to eat the rainbow—or set a goal of each meal having two different colors involved.”
