七、阅读短文,回答问题
“Zero calories(卡路里)and getting no weight(重量).” We often talk about sugar-free drinks like this. Is it really good for us to choose them?
Some people think sugar-free drinks are healthy because they don't have sugar or calories. They think having these drinks can help them lose weight.
In fact, sugar-free drinks have some sugar, but very little. Usually, if there is $0.5$ grams(克)of sugar or less in a $100$-gram drink, it can be a sugar-free drink. Sugar-free drinks still taste sweet because they use artificial sweeteners(人工甜味剂). But they have very few calories.
When we eat sweet-tasting things like sugar, they hit our brain and make us want more. Our brain tells our body to prepare itself for more sugar. When we drink a sugar-free drink, the brain receives the “sweet message”, but no sugar arrives. Because the brain is fooled, it still wants more sweets.
Some people don't drink water. They choose sugar-free drinks. But sugar-free drinks can be bad for our teeth and appetite(食欲).
