     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.
