　　Feeling tired lately? Has the doctor said he cannot find anything wrong with you? Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong. Then consider this, you might be in a state of sub health (亚健康).

　　Sub health, also called the third state or grey state, is explained as a border line state between health and disease. According to an investigation by the National Health Organization, over 45 percent of sub healthy people are middle-aged or elderly. The percentage is seven percent higher among people who work in management positions as well as students around exam time.

　　Symptoms include a lack of energy, depression, slow reactions, insomnia(失眠), agitation(焦虑), and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.

　　The key to preventing and recovering from sub health, according to some medical experts, is to form good living habits, alternate work with rest, exercise regularly, and take part in open-air activities.

　　As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements——vitamins and trace elements——that are important to the body.

　　Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy change in the digestive tract(消化道). They also say that a balanced diet is very helpful in avoiding sub health.

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.

A. foods with natural enzymes help people keep fit

B. we’d better be cautious about raw and whole foods

C. it is essential for people to protect their vital organs

D. giving up cooked and refined foods is a new lifestyle
