Beets
Beets are widely cultivated for their roots. Beetroots are rich in several nutrients, especially magnesium, but they also contain many powerful antioxidants. They are especially rich in betalains.
Betalains are a type of antioxidant that studies have shown and they may reduce the risk of cancers along the gut. [18] These antioxidants are also credited with giving beetroots their red color. Studies have also shown that betalains have strong anti-inflammatory activity. [19]
Aside from betalains, beets contain other antioxidants. FRAP analysis shows that beets contain around 1.7 mmol of antioxidants in every 100 g. [20]
