Benefits of nutrition
I am sure you have come across the saying that ‘you are what you eat’ and again that you eat to live not live to eat. Both sayings point to the fact that the foods you eat ultimately end up giving you something which keeps you alive and kicking. Good nutrition helps to keep your body fit and healthy. For young people like you, your body is growing and renewing its parts all the time.
Each day, you gain some height and also replace old cells. Cells of the skin, blood and bones are constantly being replaced. The food you eat then becomes part of you because it provides certain chemicals known as nutrients. These nutrients help to provide you with energy and building blocks that make you grow.
The best food for you is therefore the type that makes you grow normally and maintains strong muscles, strong bones, healthy skin and enough clean blood. They are also the types of food that reduces your chances of getting illnesses later in life.
A rule of thumb in your choice of food is that you should eat a variety of foods. That way you would be able to obtain all the nutrients your body needs. No one food would provide all the nutrients. Eating a variety of foods would ensure that all nutrients are obtained.
When you do not get all the nutrients you need from your food, you may develop what is called nutrient deficiency or malnutrition. These deficiencies can slow the growth of children. Again a person who does not get proper nutrition during the adolescent year may never reach full height.
MALNUTRITION

The other one is eating too little of the food so that you would not get the nutrient your body needs in the right amounts. This is called undernutrition. Both forms of malnutrition are not good for the body. Do you know that people who are hungry or poorly fed have difficulty learning and concentrating? ]] Yes they do. That is why it is not good to go to school on empty stomach.
