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

Raw and whole foods are usually digested moreefficiently than cooked and refined foods. When we cook foods, we destroy thenatural enzymes (酶) that are part of the food in its rawform. These enzymes were intended by nature to help us digest the food. When weconsume food without these natural enzymes, our bodies either digest the foodimproperly or allow too many nutrients to be absorbed into the bloodstream. Inboth instances, the result is obesity. When too many nutrients are absorbed atonce, the body grows fat. Improperly digested food moves slowly through thedigestive tract, where it becomes increasingly acidic. To protect its vitalorgans from this acidic waste, the body changes the acid into fat and stores itsafely away from the organs.

Processed foods contain chemical elements, which mightconfuse the appetite mechanism that tells us when we’ve had enough to eat; as aresult, people often overeat. Processed foods also upset the digestive cycle.The body will either identify these foods as allergens and then store themsafely away from the organs as fat, or the remains of undigested food willbecome acidic and enter the bloodstream as acid waste, which will stick to theblood vessel walls and block the passage of vital oxygen and nutrients headingfor the body’s cells. The body’s metabolism (新陈代谢)becomesinactive, and the result is weight gain and obesity.

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

To stop this vicious(恶性的)circlein its tracks, people need to consume food and supplements that will neutralize(使…中和) the acid alreadyaccumulated 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 andavoid the foods that cause acid accumulation and consume the foods thatincrease enzyme production. If you truly want to change and help your body healitself, you need to take an active approach.
