Julianne: Do you know anything about health food?
Karly: It is so popular among people to preserve health now, so I read some books about health food.
Julianne: Can you give me some examples?
Karly: Drinking warm and fresh water in the morning on wakening up is one of ways to keep healthy.
Julianne: Really? Why we must have warm and fresh water?
Karly: Warm water can be good for your stomach, which is empty at that moment. And freshness can keep the water active to clean your digest system.
Julianne: Anything else?
Karly: Yogurt, because it has protein, vitamins and it is acidic. If you drink it everyday, your stomach will be more comfortable.
Julianne asks Karly about health food and concrete examples. Karly lists warm and fresh water and yogurt and explains the reason.
