Does cooking food destroy its potential vitamin levels?

Most vitamin losses are minimal with this cooking method, including vitamin C. However, due to long cooking times at high temperatures, the B vitamins in roasted meat may decline by as much as 40%.

How does cooking affect the nutrients in food?
