6. Lycopene-Rich Foods
There is a growing body of research to suggest that consuming foods rich in lycopene can lower your risk for certain types of cancer, particularly prostate cancer [17]. Lycopenes are a type of antioxidant in the carotenoid family that gives tomatoes, watermelons, and grapefruits their red and pink colors. As a whole, carotenoids have been associated with a lower risk of lung and colorectal cancer [18]. Tomatoes*, guava, watermelon, papaya, grapefruit, and cooked red peppers are all good sources of lycopene.
*Note: Lycopene is actually more concentrated in processed tomato products like sauces, and pastes, and is not degraded by the cooking.
7. Beta Carotene-Rich Foods
Dietary carotenoids* have been linked to a lower risk of developing lung cancer, however, more research needs to be done to determine the effect of consuming beta-carotene through food on cancer prevention [18]. Carrots, sweet potatoes, and dark leafy greens like kale and spinach are excellent sources of beta-carotene.
