根据下面资料，回答36-38题
When I was at school, our teacher told the class "You are what you eat. " My friends and I would laugh and call each other "hamburger"(汉堡) and "biscuits". Our teacher was trying to show us the importance of eating the right food to stay healthy.
This was 30 years ago when there were big movements to make British people healthier. Wes tar ted to eat boiled potatoes instead of French fries and drink fat-free milk instead of whole milk. At first I felt my potatoes had no taste at all. But after a while I started to prefer healthier food because I felt stronger and I didn′t get sick so often.
So we agree that you become what you eat. Do you know what your friends eat just by looking at them When you know the effects of different types of food, you can use your knowledge well and eat what you want to become.
Food has been so important to our health. Everyone has their own advice to give, which they have read about or have been told by older people. However, some of these pieces of advice seem to disagree with each other. For example, some say "Eating chocolate makes you fat," while others say "Chocolate contains the important minerals (矿物质)like iron and magnesium (镁)." In fact, what we need to find out is what type of chocolate to eat and how much of it to eat.
