Beets

Beets, usually known as beetroot, are the roots of a vegetable called Beta vulgaris. They have a moderate flavor and are high in fiber, potassium, iron, folate, and antioxidants. Beets contain up to 1.7 mmol of antioxidants per 3.5 ounces, according to an FRAP study (100 grams). They're particularly high in a type of antioxidant known as betalains. These are responsible for the reddish color of beets and have been connected to health benefits. Several in vitro studies, for example, have linked betalains to a decreased incidence of colon and digestive tract malignancies.

Beets also contain additional chemicals that may aid to reduce inflammation. According to one study, ingesting betalain capsules manufactured from beetroot extract considerably reduced osteoarthritis pain and inflammation.
