  1. Small red beans 13727 (dry)
  2. Red kidney beans 13259 (dry)

The antioxidant capacity is affected by cooking. For example, the russet potato has a TAC/serving of 4882 (raw) and 4649 (cooked), whereas red cabbage has a TAC/serving of 788 (raw) and 2359 (cooked).

Just because a vegetable has a low antioxidant rating doesn't mean it isn't packed with a wide range of beneficial phytonutrients (aka phytochemicals). For example:

  • onions and beans contain Quercetin (a flavonoid)
  • carrots, peppers and tomatoes contain Carotenoids
  • tomatoes contain Lycopene
  • carrots contain Beta-carotene and Lutein
  • cruciferous vegetables contain sulforaphane and dithiolthiones
