Don’t Lose Your Vegetables’ Vitamins
Water-soluble vitamins like vitamin C, riboflavin, thiamin and folate can be destroyed by exposure to air, water or heat. Keep your vitamins from escaping:
Cook vegetables in a small amount of water, just enough to keep the pan from scorching.
Steam, microwave or stir-fry vegetables instead of boiling to reduce the amount of time they are exposed to heat.
Cooler temperatures help preserve vitamins; store produce in the refrigerator.
Cut vegetables close to cooking and serving time to decrease the amount of surface exposed to air.
