The way you prepare, store and cook food can greatly affect the amount of folic acid in your food.To prevent the loss of folic acid from your food:

• Store in tightly covered containers in the refrigerator.
• Peel and chop vegetables and fruit just before cooking.
• Cook or steam your food in small amounts of water for as short a time as possible.
• Serve vegetables and fruit raw more often.
• When stir-frying, use the highest heat so that vegetables start cooking right away.
