Food is the things that we eat to give us energy to live. Food gives us the fuel we need to move around, keep warm and think. Without food our body couldn’t grow or repair itself.
The “stuff” in food that keeps are bodies healthy are called macronutrients which include carbohydrates, protein and fats; and micronutrients which are vitamins such as A, B, C and minerals such as iron and calcium; and even smaller nutrients called phytochemicals which we are learning, are very important too!
Every food has a certain number of calories. For example each gram of carbohydrates has 4 calories and each gram of fat has 9 calories. The number of calories that we need every day depends on our age whether you are a boy or a girl, how tall you are and how active you are.
About 60% of the calories you burn every day are used to keep your heart, brain and other organs working. Physical activity also burns calories which can help keep you at a healthy weight.
But these days, we often eat too much food or eat the wrong types of food which can lead to being overweight or diseases like diabetes or heart disease.
