Question

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.

Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.

Processed foods contain chemical elements, which might confuse the appetite mechanism  (新陳代謝) that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism becomes inactive, and the result is weight gain and obesity.

The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.

To stop this vicious（惡性的）circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.

【解析】

試題分析：本文講述的raw foods or whole foods對人體的好處，倡導人們躲食用這樣的健康的食品。

1.推理題。根據(jù)文章第一段可知eating raw foods or whole foods可以減少體內(nèi)acid的積累，可以讓我們的消化更為有效健康。說明本文的目的在于建議人們多吃這樣的食物。故A正確。

2.推理題。根據(jù)文章第二段1,2行Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form.可知含有the natural enzymes (酶)的食物可以幫助我們更高效地消化食物。幫助我們保持健康。故B正確。

3.細節(jié)題。根據(jù)文章第二段3,4,5行When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity.可知這些處理過的食物會導致人們發(fā)胖。故C正確。

4.推理題。本文主要講述了這些raw foods or whole foods的好處，接下來就應(yīng)該是向我們介紹那些這樣的食品適合人們食用。故D正確。

5.推理題。通過全篇的閱讀可以看出：本文主要講述的是食用raw foods or whole foods對我們的身體的好處。故B正確。
