Fats

Types of fat include vegetable oils and animal products such as butter and lard. Fats can reach temperatures higher than the boiling point of water, and are often used to conduct high heat to other ingredients, such as in frying or sauteing.

Cookies, crackers and other commercial baked goods made with partially hydrogenated vegetable oils may be high in trans fat. French fries, donuts and other commercial fried foods are major sources of trans fat in the diet.
