Do sugary drinks cause overweight? While we know that sugary drinks have calories (卡路里), which are believed to cause overweight, many questions remain. For example, is soda any better? Do you need a sports drink after going to the gym? Here are the facts to some common misunderstandings.
Misunderstanding 1: Clear soda (无色汽水) is healthier than dark soda.
The truth: The dark color of teeth has something to do with the coloring (着色剂) in soda. Lisa R. Young, a professor of Nutrition at New York University said. But the big difference between clear and dark sodas is the caffeine content (咖啡因含量). Since a bottle of soda, such as Coca-Cola and Sprite (雪碧), has less caffeine than that in a cup of coffee, most soda drinkers probably don't need to worry about what to choose.
Misunderstanding 2: If you need caffeine to cheer you up, you should choose an energy drink rather than coffee.
The truth: There are more sugar than caffeine in energy drinks such as Red Bull (红牛). Energy drinks may be easier to drink. But a cup of coffee has between 95 and 200 milligrams (毫克) of caffeine while Red Bull has about 80mg per the same amount, according to US medical research group Mayo Clinic.
Misunderstanding 3: If you go to the gym, you need a sports drink.
The truth: It would be easy to think that you need a sports drink any time you sweat (出汗).
But the truth is that the energy in your body won't be used up until you've done more than an hour of training. So you only need to drink some water after a 45-minute exercise on the running machine.
