Nutrition is the set of processes by which humans ingested, absorbed, transformed and used the substances found in food and have to meet four major objectives:
1. Give energy to maintain their functions and activities,
2. Provide material for the formation, growth and repair of body structures for reproduction,
3. To provide the substances needed to regulate metabolic processes, and
4. Reduce the risk of some diseases.
Food is instead the process by which the outside world took a series of substances contained in foods that form part of our diet is necessary for nutrition.

Food is, therefore, any product or substance that when consumed gives equivalent materials that meet a nutritional function in the body.
Bearing in mind these concepts, we can realize that the secret to good nutrition is to learn to change our lifestyles, which are often altered by the fast food, stress, sedentary lifestyle. Likewise, we must learn to know the different food groups and the best ways to combine them.
