What food prevents cancer?

Hello, green vegetable. Dark green vegetables have anti-cancer effect. Such as spinach and lettuce, are rich in antioxidants, including folic acid and lutein. Based on this, scientists suggest that the darker the color of vegetables, the higher the antioxidant content and the stronger the anti-cancer effect. Vitamin C contained in apples can hinder the production of nitrosamines, destroy some enzyme activities produced during the proliferation of cancer cells, and even transform the generated cancer cells into normal cells.
