Reading 1A SWEET LOVE Many scientists believe our love of sugar may actually be an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects the 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 an addictive drug, one that doctors recommend we all cut down on. "It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar," says scientist Richard Johnson. One-third of adults worldwide have high blood pressure, and up to 347 million have diabetes. Why? "Sugar, we believe, is one of the culprits, if not the major culprit," says Johnson. Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to be very efficient in storing 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 even use sugar to replace taste in foods that are advertised as low in fat. So while the foods appear to be healthier, large amounts of sugar are often added. But some people are fighting back against sugar and trying to create a healthier environment. Many schools are replacing sugary desserts with healthier options, like fruit. Other schools are trying to encourage exercise by building facilities like walking tracks so students and others in the community can exercise. The battle has not yet been lost.

阅读1A 甜蜜的爱 许多科学家认为，我们对糖的喜爱实际上可能是一种瘾。 当我们吃或喝含糖食物时， 糖进入我们的血液，影响我们大脑中让我们感觉良好的部分。 然后，美好的感觉消失了，让我们想要更多。 所有美味的食物都有这种作用，但糖的作用尤其强烈。 通过这种方式，它实际上是一种令人上瘾的药物，医生建议我们都减少使用。 “似乎每次我研究一种疾病并找出第一个原因时，我都会找到回到糖的方法。” 科学家理查德·约翰逊说。 全球三分之一的成年人患有高血压，高达3.47亿人患有糖尿病。 为什么？ 约翰逊说：“我们认为，糖是罪魁祸首之一，如果不是罪魁祸首的话。”。 我们的身体被设计成只靠很少的糖生存。 早期人类通常食物很少，所以我们的身体学会了将糖作为脂肪储存起来非常有效。 这样，我们就为没有食物的时候储存了能量。 但今天，大多数人已经绰绰有余。 所以，曾经拯救我们的东西现在可能正在杀死我们。 那么，解决方案是什么？ 很明显，我们需要少吃糖。 问题是，在当今世界，这是极难避免的。 从早餐麦片到晚餐后的甜点，我们的食物越来越多地被它填满。 一些制造商甚至使用糖来代替广告中低脂肪食品的味道。 因此，虽然这些食物看起来更健康，但通常会添加大量的糖。 但有些人正在抵制糖，并试图创造一个更健康的环境。 许多学校正在用水果等更健康的选择取代含糖甜点。 其他学校正试图通过修建步行道等设施来鼓励锻炼，这样学生和社区中的其他人就可以锻炼了。 这场战斗尚未失败。
