Buy Red: A Closer Look at Anthocyanins

Buy Red: A Closer Look at Anthocyanins
  • Anthocyanins are water-soluble plant pigments in the flavinoid class of phytochemicals or plant chemicals.
  • These healthful pigments can appear purple, red, blue, and almost black depending on their concentration and pH. They give eggplants, purple cabbage, purple grapes, cherries, strawberries and blackberries much of their reddish to almost black color. Eggplant skin has almost 750 mg of anthocyanin per 100 grams!
  • Anthocyanins are also found in large amounts in blue or purple corn, purple potatoes, and black rice, olives, soybeans and sorghum.
  • Smaller amounts of anthocyanins are found in red apples, asparagus, peas, and even bananas have some.
  • Not all plants get their red to purplish coloring primarily from anthocyanins. Tomatoes get their red coloring mostly from lycopene. Beets get their purplish coloring largely from betalains. These other red to purple phytochemicals may also have health benefits but do not appear to impact blood lipids as the anthocyanins do.
“Fresh fruits, vegetables, legumes and whole grains contain more than just vitamins and minerals. The pigments they contain may help reduce the risk of many diseases.” -- Dr. James J Kenney, PhD, FACN
