Why is it important to eat healthy foods?

All foods have their own set of nutrients. They may contain fibre, minerals, and vitamins that will aid in the metabolism and other processes in your body. Here are some examples of nutrients and components that you will find in your food

  • carbohydrates - these are the preferred source of energy for your body. All of your organs need carbohydrates in order to function. Your heart, your brain, your lungs, and the rest of your organs will rely on energy in order to function. These carbohydrates will also be used to repair the tissues of your body. They will be used to keep you warm and they will also be used to power your muscles when they move
  • protein - this is important for repairing your muscles. It can also be used as a source of energy for the body
  • fat - this allows important vitamins to be transported throughout your body. It is a highly concentrated source of energy as well
  • vitamins - there are a lot of vitamins in healthy food and they perform different functions in your body. For instance, vitamin D helps in making your bones healthy. Vitamin C is needed for healthy wound healing. Vitamin A will keep your eyes clear and healthy
  • minerals - there are several minerals that are useful for your body. For instance, iron is used for transporting oxygen through the blood. Calcium is needed for strong bones and teeth
  • fibre - this keeps your digestive system clean and healthy. It also controls your cholesterol levels and your blood sugar levels
