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 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 (新陈代谢)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(恶性的)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】

试题分析：文章强调了未加工食品和纯天然食品对健康的重要性。经过加工的食品往往含有破坏人体消化和食欲机制的化学物质，不利于人体健康。而且，选择适合的未加工食品类型也是很必要的。

1.根据第一段和第二段“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...”可知，文章主要讲的是食用未经加工的食物更有助于消化吸收，从而保持健康。故选A。

2.根据第二段“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.”可知，酶有助于消化食物，如果没有酶，食物的消化就会不当，或会吸收过多的营养物质，最终导致肥胖。由此可见，酶能帮助人们保持身体健康。故选B。

3.根据第三段“Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat...the result is weight gain and obesity”可知，经过加工的食物含有的化学物质会使食欲机制紊乱，会进食过量，最终导致肥胖。故选C。

4.根据最后一段“ Eating the right types of raw and whole foods can help...If you truly want to change and help your body heal itself, you need to take an active approach.”可知，选择合适的未加工食品类型很有帮助，如果你想调理身体，就需要采取一种积极的方法。接下来可能会讲未加工食品的类型。故选D。

5.根据第一、二、五段“eating these types of food reduces the risk of acid accumulation in your body

Raw and whole foods are usually digested more efficiently...These enzymes were intended by nature to help us digest the food...Eating the right types of raw and whole foods can help.”可知，纯天然的、未加工的食物更好消化吸收，保持身体健康。选择合适自己的未加工食品的类型也很重要。故选B。
