Beets - Our Food of the Week
Did you know that the pigment that provides the rich red color of beets is also a powerful antioxidant and cancer fighting agent?
Beet roots contain a unique class of phytonutrients called betalains. Betacyanin is the red pigment that is concentrated in red beets, and betaxanthin, the yellow-orange pigment found in yellow beets.
These health-promoting phytonutrient pigments may be partially responsible for beets' suggested role as a chemoprotective food. In one study, liver antioxidant enzymes were found to increase in animals fed beet fiber. Since these enzymes protect the liver from free radicals, they are thought to prevent the beginnings of cancerous activity. In a human clinical trial, beet juice was found to be a potent inhibitor of cell mutations that are normally caused by nitrosamines, metabolic byproducts of nitrates, which are chemical preservatives commonly used in processed meats.
It turns out that beet roots are not the only part of the plant offering protection against free radical damage'beet greens also have amazing antioxidant potential. In one study that compared them to spinach, broccoli, carrots, onions and celery, beet greens were found to have the highest phenolic phytonutrient content as well as the greatest ability to absorb oxygen radicals (a marker of their antioxidant capacity).

Healthy Cooking Tips for Beets
Cleaning and Peeling: To minimize bleeding, wash beets gently under cool running water, taking care not to tear the skin; the tough outer layer helps keep most of beets' pigments inside the vegetable. If you are going to roast or boil your beets it is best not to peel beets until after cooking. When bruised or pierced, beets bleed and lose some of their vibrant color, turning a dull brownish-red. To prevent bleeding when boiling beets, leave them whole with their root ends attached to one inch of stem. Rinse beet greens under cold running water before cooking.
