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 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.

[1]One out of many important things for the whole family to do is to have dinner together. Researchers began reporting the benefits of family dinner about a decade ago, focusing mainly on how it affects children. Studies show that those families who eat dinner at least 3 or 4 times a week together, benefit in many ways.

[2]Eating together helps families achieve open communication and build stronger and healthier relationships. Children have better grades at school and are better adjusted as teens and adults, and the entire family enjoys healthier nutrition. For many families, eating dinner together proves to be good and effective way to reduce the risk of youth rates of addiction, and helps to raise healthier children. It is also a great time to share the events of the day, discuss news and ideas and just be together and enjoy each other's company.

[3]During dinner time parents have better opportunity to show that the prior to their children. Sitting at the same table and sharing meals is where and when parents can find out more about their children's school performance, daily activities and attitudes toward life. When parents have all this information they can better direct their kids toward positive things in life. They also have better chance to reduce the possibility that children will get involved with alcohol, tobacco, and illegal drugs.

[4]However, family researchers say that the benefits of family dinner by no means can be considered as automatic. Parents can sit down to dinner with their kids every day and achieve nothing. _________ if there is too much arguing going on, if there is no meaningful conversation or, what is even worse, if there is just plain silence during gathering.
