Does cooking food reduce nutrients?

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 meat lose nutrients when cooked?
Nutrients can also be lost during the process of cooking meat. The extent to which this occurs is strongly influenced by the cooking method. What’s more, heating meat to high temperatures for long time periods can lead to the formation of harmful compounds that may increase disease risk.

Is overcooked meat less nutritious?
Studies of the effects of cooking and other methods of processing report no significant alterations in the protein value of meat. However, cooking at too high a temperature for long periods of time can slightly decrease the biological value of meat proteins.
