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 circle in its tracks, people need to consume food and supplements that will neutralize 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】

这是一篇说明文。本文讲述的生的食物和完整的食物对人体的好处，倡导人们多食用这样的健康的食品。

1.推理判断题。根据文章第二段“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.”可知，当我们烹饪食物的时候，我们破坏了食物中的天然酶，它是食物原料的一部分。 这些酶本来是用来帮助我们消化食物的。 当我们食用没有这些天然酶的食物时，我们的身体要么不正确地消化食物，要么让太多的营养物质被吸收到血液中。由此判断出，含有天然酶的食物可以帮助人们保持健康。故A正确。

2.细节理解题。根据文章第三段“The body’s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.”可知，身体的新陈代谢变得不活跃，结果是体重增加和肥胖。所以加工食品是不健康的，因为它们可能导致肥胖。故B正确。

3.推理判断题。根据最后一段“To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize 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.可知，为了阻止这种恶性循环，人们需要吃一些食物和补品来中和体内积累的酸。食用正确的生食和天然食品会有所帮助。由此判断出，这篇文章的主要目的是提倡吃更多的生食和天然食品。故B正确。

4.推理判断题。根据最后一段“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.”可知，你需要识别和避免那些会引起酸积累的食物，并食用那些会增加酶的食物。如果你真的想要改变并帮助你的身体自我痊愈，你需要采取积极的方法。由此判断出，在最后一段之后可能会讨论适合的生食和天然食物。故C正确。
