Question

【题目】 Many scientists believe our love of sugar may actually be an addiction (上瘾). When we eat or drink 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 particularly strong effect. In this way, it is in fact addictive, and doctors suggest we all cut down on it.

“It seems like every time I study an illness, I find my way back to sugar,” says scientist Richard Johnson. One-third of adults worldwide have high blood pressure ( 血 压 ), and up to 347 million have diabetes (糖尿病). Why? “Sugar, we believe, is one of the reasons, if not the main reason,” 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 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.

So what is the solution? It’s obvious that we need to eat less sugar. The trouble is, in today’s world, it’s extremely difficult to avoid. From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers ( 制造 商) even use sugar to replace taste in foods that are advertised as low in fat. This may make the food appear as healthier, but large amounts of sugar are often added.

But there are those who are fighting back against sugar. Many schools are offering more fruit instead of deserts. Other schools are building facilities for students to do exercise. The battle has not yet been lost.
