想要补水效果好 糖多不如糖少
But here's where it gets tricky: Beverages with more concentrated sugars, such as fruit juices or colas, are not necessarily as hydrating as their lower-sugar cousins. They may spend a little more time in the stomach and empty more slowly compared to plain water, but once these beverages enter the small intestine their high concentration of sugars gets diluted during a physiological process called osmosis. This process in effect "pulls" water from the body into the small intestine to dilute the sugars these beverages contain. And technically, anything inside the intestine is outside your body.
但是问题就在这里:糖浓度更高的饮料(比如果汁或可乐)的补水效果就不一定有含糖量低的饮料好了。和白水相比,这些饮料也许在胃里停留的时间更长一点,排空速度更慢,但一旦这些饮料进入小肠,高浓度的糖就会在渗透作用(一种生理过程)下得到稀释。这一过程会“抽出”人体的水分来稀释小肠中的饮料糖分。严格意义上来讲,小肠内部的任何物质都会排出体外。
Juice and soda are not only less hydrating, but offer extra sugars and calories that won't fill us up as much as solid foods. If the choice is between soda and water for hydration, go with water every time. After all, our kidneys and liver depend on water to get rid of toxins in our bodies, and water also plays a key role in maintaining skin's elasticity and suppleness. It's the cheapest moisturizer you'll find.
