Maintain a healthy physical and mental condition

Nutrients are the chemicals which make up all of the different variety of foods and are chemicals which we need to survive and to maintain a balanced state of health. Our body needs a daily intake of nutrients such as proteins, fats, carbohydrates and vitamins to perform daily physical activities since nutrients are the main sources of energy of the body. Other chemical compounds which are not produced by organic matter are also identified and nutrients and examples of these types of nutrients include minerals, water and oxygen amongst others.

A healthy diet is composed of meals which are rich in nutrients and which are low in refined sugars and Tran's fats. The amount of nutrients that processed foods provide is not as much as the amount of nutrients that raw or natural foods provide, which is why nutritionist strongly recommend avoiding the consumption of fast foods, desserts, or processed and refined carbohydrates. Fruits and vegetables as well as lean protein and dairy products all provide an excellent amount and quality of nutrients which the human body needs to operate at optimum levels. The learning process of an individual who is undernourished is impaired by the lack of nutrients, meaning that in order to be able to learn and memorize a person must consume regular meals which are high in nutrients. Undernourished children around the world have a much more difficult time learning than healthy children to which is why it is very important to stop hunger that affects millions of kids in impoverished countries.
