The three R’s for nutrient preservation are to reduce the amount of water used in cooking, reduce the cooking time and reduce the surface area of the food that is exposed. Waterless cooking, pressure cooking, steaming, stir-frying and microwaving are least destructive of nutrients. Frozen vegetables can be steamed.
How can we reduce the loss of nutrients in cooking?
