This KS3 Design and Technology quiz takes a second look at food. Food contains the essential nutrients needed for growth and repair of our bodies. Two important nutrients are proteins and vitamins. Foods that come from animal products are usually high in protein like fish, meat and eggs. They also contain some essential vitamins. Other vitamins are found in fruit and vegetables which is why it is important to eat a balanced diet. Fruit and veg are low in protein so vegetarians and vegans need to find alternative sources of protein.
When preparing food, sometimes things go wrong - lumpy gravy, a jelly that hasn't set. Knowing what ingredients do and something about how they work can help any cook put things right! A good example is jelly - if you don't keep it cool it will turn to a liquid because the gelatine used to solidify it melts again when its temperature rises.
