Dietary Fat

In what food source is the nutrient found?

Dietary fat is found in most animal foods such as meat and dairy products and in oils, salad dressings, and mayonnaise. Bakery products, fried foods, some gravies and sauces, and most highly processed foods also contain fat. Fat takes longer to leave the stomach than either carbohydrate or protein, so a person feels fuller for a longer period of time after eating fat.

How does the nutrient affect the body?

The body uses fat as an energy source. Any extra dietary fat is converted to body fat and stored in fat cells. The human body has an unlimited capacity to store fat. The body can use these fat stores later for energy.
