Nutrients are used by the body to perform the basic functions of life, including digestion, respiration and circulation. Many nutrients are necessary in small amounts, while others are used in larger amounts to produce cellular energy. There are two types of nutrients: organic and inorganic. Organic nutrients are those that are produced by plants or animals. They are not broken down. Minerals, on the other hand, are not produced. However, they are consumed as a byproduct of the burning of food.

Fats are another important nutrient, and are essential for the body. Fats are found in many foods, such as nuts and avocados. Monounsaturated fats, which are good for the heart, are commonly found in olives and canola oil.

Vitamins are a group of essential nutrients, and are also considered micronutrients. Vitamins are organic molecules, and contain carbon. While some plants can synthesize ascorbic acid (vitamin C) on their own, it is important to get it from food.

Lipids, which are a group of nutrients that contain 9 kcal per gram, are essential for human nutrition. Lipids have the highest calorific value of the three classes of macronutrients. Besides storing energy, lipids are needed for the creation of biologically important molecules.

Aside from the three classes of macronutrients, humans require other types of nutrients, which are called micronutrients. Micronutrients, which are the smaller amounts, are necessary for healthy growth and development.
