Food and Health{{/B}} 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 the diet as well, especially cancer of the colon (结肠). Different cultures are more likely to develop certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates (硝酸盐)commonly used to preserve color in meats, and other food additives, accused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which [单选题]夹套式换热器的优点是( )。
