Many scientists believe our love of sugar may actually be an addiction (瘾). When we eat sugary foods, the sugar enters our blood and influences parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has a stronger effect.
“It seems that every time I study an illness, I find the sugar is the main cause,” says scientist Richard Johnson. One third of adults have high blood pressure, and up to 347 million adults have diabetes (糖尿病). Why? “Sugar, we believe, is one of the main reasons,” says Johnson.
Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to keep sugar as fat. In this way, we had energy stored for the time when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us.
It’s clear that we need to eat less sugar. The trouble is, in today’s world, it’s very difficult to avoid. Our foods are increasingly filled with it. Some manufacturers (制造商) even add much sugar to foods that are advertised (做广告) as what are low in fat. This may make the food appear healthier, but too much sugar may be harmful.
But there are those who are fighting back against sugar. Many schools are offering more fruit instead of desserts. Other schools are building facilities for students to do exercise. The battle (战斗) has not yet been lost.
