Don't Fear the Red! Beets are a unique source of phytonutrients called betalains. Betanin and vulgaxanthin are the two best-studied betalains from beets, and both have been shown to provide antioxidant, anti-inflammatory, and detoxification support. The detox support provided by betalains includes support of some especially important Phase 2 detox steps involving glutathione. Although you can see these betalain pigments in other foods (like the stems of chard or rhubarb), the concentration of betalains in the peel and flesh of beets gives you an unexpectedly great opportunity for these health benefits. Americans get way too little fruit and veggies. Smoothies are a great way to pack your diet with healing nutrients and healthful fiber.
