The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more prone to contract certain illnesses because is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated coes. Sometimes sim

我们说吃的食物对我们的健康有深远的影响。尽管科学知识已经改善了我们所生产的食物，让它们变得更合适我们食用，不过在同时，也使很多的食物变得不适合被食用。 很多研究表明大概有80%的人类疾病是由日常饮食所引起的，另外有40%的癌症也是有饮食引起的，提别是结肠癌。 不同的养殖方法更可能染上疾病，这已经不是什么新发现了。 在1945年，政府的研究人员发现通常被用于保持肉的颜色（答案）的硝酸盐与亚硝酸盐和别的一些食品添加剂会致癌。 但是，这些致癌添加剂还存在我们的食物中，同时我们更难懂得在包装袋上面所写的食品添加剂哪些是有益的哪些又是有害的。那些被我们所食用的添加剂有些时候是间接进入我们的身体的。农民经常给牛和一些家禽食用青霉素，所以青霉素也在牛奶中被找到。有时，与青霉素类似的药物的使用不是为了治病的目的而是为了效益的原因。 农民们想让动物们变肥然后卖个好价钱。 尽管食品药品监管部门已经尽力在控制这些行为了，但是，这种行为还在继续着
好像雅思里面看到过类似的文章，不错的
