       Do you drink milk every day? Milk is good for health. It is one of the healthiest foods. But do

you know the best ways to drink milk? Here are some suggestions.    

       ◆ You should not drink milk on an empty stomach.  Milk is not enough for a meal in itself. You

need other foods with the milk, like bread and biscuits.  They help you to take in more of the milk's

nutrients (营养).    

       ◆ If there's no milk, soybean milk (豆浆) is a good choice.  People drink milk because it gives the

body calcium (钙).  So you can try foods with lots of calcium,  these could be bean products, like tofu,

nuts, or shrimp (虾).    

       ◆ When is the best time for a glass of milk? At breakfast or an hour or two before dinner. Milk

helps you sleep. You can have a glass before you go to bed.    

       ◆ Iced milk may taste good, especially in summer.  But it may not be good for your health.  Iced

milk gives your body less calcium.
