What are carbohydrates made from and why are they important?

"Carbohydrates are the body's energy.
  1. simple sugars (simple carbohydrates), such as fructose, glucose,and lactose, which also are found in nutritious whole fruits
  2. starches (complex carbohydrates), found in foods such as starchy vegetables, grains, rice, and breads and cereals"

When we first eat carbohydrates and sugar the body needs to break them down to simple sugars- it is the simple sugar that then is absorbed into the blood stream.

The food which contains simple sugars such as white flour, and white rice are easily broken down and the blood sugar levels rise quickly. The complex carbs, however, (whole grains) are broken down slowly which allows the blood sugar levels to rise quickly. This is the healthier option (less risk of diabetes).

What are proteins?

Why is it important to get a varied diet?

It is important to keep a varied diet because, you need calories and kilojoules to get energy from food. The whole body needs calories and kilojoules to function. If you eat only carbohydrates for a month (for example) it will make you fat. If you eat a little bit of everything, then you'll be healthy.
