KS2 Science Quiz - Healthy Eating (Questions)

In this KS2 Science quiz we take a closer look at healthy eating, nutrition and a balanced diet - all vital if we want to maintain a healthy body.

Healthy eating is about the balanced diet your body needs to keep it in good condition. We all know that eating things like crisps, chocolate, sweets and soft drinks alone would be bad nutrition and would not make up a healthy diet. They're ok in small amounts but we need other things - fruit and vegetables, proteins, vitamins and minerals for example - in a balanced diet. It's important that we eat a variety of foods to get all of the nutrients we need to stay healthy.

But what, exactly, is needed to be healthy? Why are vitamins important and in which foods can we find them? See how much you know by trying this quiz on healthy eating and nutrition.
