What role do phytochemicals in fruits play in cancer prevention?
Phytochemicals are bioactive compounds found in fruits that have been shown to possess anti-cancer properties. These include flavonoids, carotenoids, and polyphenols. For example, lycopene, found in tomatoes and watermelon, is linked to a lower risk of prostate cancer. Similarly, quercetin in apples and onions has anti-inflammatory and anti-cancer effects.
