Orange foods
They fight stomach and ovarian cancers. ß carotene, responsible for the orange color in sweet potatoes, pumpkins, carrots and squash has been shown to have anti carcinogenic effects on stomach cancer by promoting cancer cell destruction. Caffeic acid, an organic compound found in carrots and sweet potatoes, has been shown to slow down breast cancer growth and even promote cell death as well. Eat these orange foods at least three times a week.
Yellow foods
They fight esophageal and stomach cancers. Citrus fruits such as grapefruit, lemons, tangerines and papaya are rich in C vitamin, a powerful antioxidant which has been proved to be protective against almost all cancers, especially mouth, throat and stomach cancers, and colon as well. These foods are also rich in flavonoids that inhibit tumor cell growth and detoxify against harmful substances. Add these fruits to your meal at least twice a day.
