When our body digests food, the nutrients go to all parts of the body. These nutrients are proteins, carbohydrates, vitamins, minerals, fats and water.
Every type of food contains different nutrients, so it’s important to eat a healthy and varied diet.
Proteins help us grow and repair our body. We find them in meat, fish, milk, eggs and
legumes.Carbohydrates include starches
Vitamins and minerals in vegetables and fruit help us to grow and keep our body healthy because they protect us from many illnesses.
Fats give us energy. They are two types of fat: animal fats in eggs, butter, fish and meat and vegetable fats in olives and nuts.
Water is also essential for our body because blood is mostly water. Water dissolves the nutrients and takes them to all parts of our body. Although humans can survive for an extended period without food, we can only survive for about three days without water.
LET’S INVESTIGATE
Use and encyclopaedia or the internet. Write what the iron is and why we need it.
Iron is a mineral that is an important part of our red blood cells. It is needed to carry oxygen from our lungs to our cells, muscles and organs. If we do not get enough iron, not enough oxygen will be delivered to our muscles and organs. Without enough oxygen, our muscles and organs cannot work properly and we will feel tired and weak.
