What is Nutrition? | Definition, Types, Nutritional Value, Importance, & Food

Nutrition is how we get the food we need to grow healthy. Vitamins and minerals help our bodies function and grow.

Why is Nutrition important for children?

Eating the right foods is especially important for children, as they are still growing. Children’s bodies need nutrition to develop strong bones and muscles. If you don’t get all the vitamins and minerals you need as you grow up, you won’t be as tall and healthy as you normally would be.

My plate

The United States Department of Agriculture (USDA) has developed a plate picture to help us ensure that we are getting all the nutrients we need at every meal. Here is the picture:

As you can see, each of the five food groups is plotted on the plate. Note that servings of vegetables and grains are slightly larger than servings of fruit and protein. This gives you an knowledge of ​​what foods to eat and the amount of each.

The USDA also provides other guidelines for healthier eating. Some can help you:

  • Drink skim or low-fat milk.
  • Eat whole grains for your cereal. An example is bread instead of white bread.
  • Drink water instead of sugary drinks.


Calories are a measure of the amount of energy present in food. When we eat, we increase calories and this gives us energy to run and do things. If we eat more calories than we use to move, our bodies store the calories as fat. If we use more calories than we take in, our bodies will start burning stored fat.
