How does cooking affect the nutrient content of foods?
In fact, boiling reduces vitamin C more than any other cooking method. Broccoli, spinach and lettuce may lose up to 50% or more of their vitamin C when boiled ( 4, 5 ). Because vitamin C is water-soluble and sensitive to heat, it can leach out of vegetables when they’re immersed in hot water.
Why do you lose vitamins when you cook in water?
Most water-soluble vitamins are lost through cooking in water. Also, cooking in water can decrease the amount of potassium, calcium, and sodium in foods, especially from overcooking or dicing foods into small bites. To avoid excessive loss, use less water when cooking or try steaming.
What kind of nutrients are destroyed by heat?
However, some vitamins and nutrients are heat-sensitive. The University of Michigan says that when fruits or vegetables are cooked at high temperatures or for long periods of time, heat-sensitive nutrients such as B vitamins, vitamin C and folate are more likely to be destroyed.
What kind of vitamins are lost when you cook vegetables?
Vitamin Losses. Columbia Health, a division of Columbia University, notes that some vitamins, particularly many B vitamins and vitamin C are lost or diminished through cooking vegetables in water because they leach into cooking water.

Are there any nutrients that are destroyed by cooking?
These statements are nonsense. Protein and minerals are not destroyed by heat. Some vitamins are lost in cooking, but you still get plenty if you have a reasonably varied diet. The enzymes in food that are destroyed by heat are of no use to you anyway; you make your own enzymes for digestion of your food.
