Can vitamins be unknowingly destroyed in the preparation of food?
Yes. Vitamins are sensitive to heat, air, humidity, and light. As a result, cooking foods or even just exposing them to the kitchen environment may actually destroy vitamins. To avoid vitamin loss, do not soak or overcook your food; trim and chop sparingly; add as little water as possible; re-use the water in which you cooked your vegetables for soups, stews or sauces; do not keep food on a warming plate, but re-heat quickly just before eating.
