Another study points to mushrooms possibly lowering the risk of breast cancer, due to compounds like glutathione, ergothioneine, and polysaccharides. Medicinal varieties such as reishi, turkey tail, shiitake, and maitake are known to enhance immune responses against tumors, with PK polysaccharide from turkey tail showing promise in cancer treatment.

4. Allium Vegetables

Vegetables in this category—such as onions, garlic, shallots, and leeks—are believed to help defend against cancers of the digestive system, including colon cancer.

Research suggests that onion and garlic offer “promising biological activities that are indicative of their potential as potent antioxidant and anticancer agents.”

5. Wakame

Wakame, a type of edible seaweed, has shown potential in suppressing the development of breast, colon, and kidney cancer cells, although these findings are based on animal studies and lab testing. Further research is needed to determine its effects in humans.

It also provides approximately 42 micrograms of iodine per serving.

6. Lycopene-Rich Foods

Lycopene is a plant-derived compound (phytochemical) not produced by the body, and therefore not classified as a vitamin or mineral.

Hope Barkoukis, Ph.D., chair of the nutrition department at Case Western Reserve University School of Medicine, explains lycopene’s role: “This means it can reduce the presence of harmful compounds in your body called free radicals.”

Consuming lycopene-rich foods such as tomatoes and watermelon may help reduce the risk of cancer, heart disease, and other chronic conditions.

7. Beta Carotene-Rich Foods

Foods rich in beta-carotene—like carrots, sweet potatoes, butternut squash, and other orange or yellow fruits and vegetables—are believed to be beneficial, although further studies are needed to confirm their role in cancer prevention.

8. Fatty Fish

Fish such as salmon, sardines, herring, albacore tuna, mussels, and anchovies may contribute to reducing cancer risk when eaten regularly. These types of fish are high in vitamin D and omega-3 fatty acids, both of which are believed to support disease prevention, including cancer.
