does cooking destroy vitamin b12?
Cooking can lead to a reduction in vitamin B12 content, but the extent of the loss depends on the cooking method and the type of food. Water-soluble vitamins like B12 are more easily lost during cooking than fat-soluble vitamins. Boiling vegetables can cause a significant loss of vitamin B12, as the vitamin leaches out into the cooking water. Microwaving or steaming vegetables helps retain more of the vitamin. Cooking meat at high temperatures, such as grilling or frying, can also cause a loss of vitamin B12. However, cooking meat at lower temperatures, such as in a slow cooker, helps preserve the vitamin.
which vitamins can be destroyed by heat?
Vitamin C, thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), vitamin B6, biotin (vitamin B7), and folate (vitamin B9) are all water-soluble vitamins that can be destroyed by heat. Cooking methods that involve high temperatures, such as boiling, frying, and grilling, can cause these vitamins to leach out of food or break down completely.
