Grapefruit
Vitamin C — an antioxidant found in many fruits and vegetables such as grapefruit, oranges, bell peppers, and broccoli — helps to prevent the formation of cancer-causing nitrogen compounds. Diets high in vitamin C have been linked to a reduced risk of cancers of the stomach, colon, esophagus, bladder, breast, and cervix. These results are specific to vitamin C-rich foods, rather than supplements, which seem less reliable. So be sure to pile fruits and veggies on your plate – they’re excellent for your body in so many ways!
Pomegranates
Pomegranates are chock full of ellagic acid — the latest phytonutrient to enter the scene (although it’s been quietly hanging out in berries, nuts, and pomegranates for millennia). In laboratory and animal studies, ellagic acid has been shown to inhibit cancer cell growth and deactivate cancer-causing compounds. To take advantage of these health properties, incorporate pomegranate seeds into smoothies or use them to top off a bowl of yogurt or cereal. Other foods rich in ellagic acid include raspberries, blackberries, strawberries, walnuts, pecans, cranberries, and grapes (red, black, purple).
