Wellness dietitian Lindsey Wohlford notes, “Choosing nutritious foods regularly may help reduce your cancer risk over time, but there’s no absolute guarantee that any food can prevent cancer.”
1. Cruciferous Vegetables
Eating vegetables like broccoli, cauliflower, and Brussels sprouts has been linked to a lower risk of several cancers, including breast, esophageal, oral, and kidney cancers.
2. Turmeric
Turmeric contains curcumin and other protective compounds with antioxidant and anti-inflammatory properties. It may help slow cancer cell growth, protect cells from damage, support joint health, and even reduce signs of aging.
3. Mushrooms
Certain mushrooms may lower breast cancer risk thanks to compounds like glutathione, ergothioneine, and polysaccharides. Medicinal mushrooms—such as reishi, turkey tail, shiitake, and maitake—have been studied for their ability to support antitumor immunity, with turkey tail’s PK polysaccharide showing promise alongside cancer therapies.
4. Allium Vegetables
Onions, garlic, and other allium vegetables contain compounds with strong antioxidant and potential anticancer effects.
5. Wakame
This seaweed is rich in iodine, offering roughly 42 mcg per serving, and may provide additional health benefits.
6. Lycopene-Rich Foods
Tomatoes, watermelon, and other lycopene-rich foods may help reduce the risk of certain cancers, heart disease, and chronic health conditions.
7. Beta Carotene-Rich Foods
Carrots, sweet potatoes, and butternut squash are high in beta carotene, which is being studied for its potential role in cancer prevention.
8. Fatty Fish
Oily fish like salmon, mackerel, and sardines are rich in omega-3 fatty acids, which may help reduce inflammation and support overall health, potentially lowering cancer risk.
