How does cooking affect the nutrients in food?

Heat diminishes vitamins and phytonutrients (beneficial plant compounds other than vitamins or minerals) in fruits and vegetables. The longer they cook, and the higher the temperature, the greater the nutrient destruction. Even chopping food can begin to erode some of the nutrients.

Does reheating food destroy nutrients?

The Verdict: When reheating leftovers, microwaving is best

While the mineral content of food isn’t affected by microwaving, the vitamin content does take a bit of a hit when food is reheated. (Vitamin C and the B vitamins are especially affected.) Still, the microwave isn’t the villain that it’s often made out to be.

Does processing destroy minerals?

But food processing also has drawbacks. Depending on the degree of processing, many nutrients can be destroyed or removed.
