Unit 11   Eating the Right Things

Part Ⅰ   Getting ready
One of the reasons why we eat food is to get energy. When the amount of food we eat balances the amount of energy our body needs, there is no surplus to be changed into body fat. This is the ideal situation.

A  The following words and phrase will appear in this unit. Listen carefully and study the definitions.
   1. excessive: too extreme
   2. deficiency: not having as much as needed
   3. efficacy: capacity to produce a desired effect
   4. caffeine: a chemical substance found in coffee, tea, and cocoa, which makes your brain and body more active
   5. decaf: coffee that has had most of the caffeine removed from it
   6. obesity¹: the condition of being extremely fat
   7. kebab: food that consists of small pieces of meat and sometimes vegetables that have been put on a thin metal rod and grilled²
   8. polystyrene: a very light, plastic substance used especially to make containers or as an insulating material   ([化]聚苯乙烯)
   9. organic food: food free from chemical injections or additives⁴
  10. yoghurt: a slightly sour, thick liquid which is made from milk that has had bacteria added to it

   To grow and maintain healthy we must eat the right kinds of food and the right amounts as well. A balanced diet is one that has the right amount of all the food needed by the body. It has some food for growth, some food for energy, some food for protection against disease and some water. So what kinds of food should we eat every day?
