There exists some scientific evidence that eliminating cooked food from the diet is beneficial. However, enzymes are produced by the body to aid digestion, whether the food is cooked or raw. A raw food diet is high in fresh food, which is 35% richer in nutrients than some kinds of processed food. Professor Benos acknowledges that eating a raw food diet may have some positive effects: ‘A raw food diet is high in fresh food, which is richer in nutrients than some kinds of processed food.
The diet also encourages more chewing and takes longer to digest so it is more satisfying. As a result we do not eat more than we need.’
Health Debate: A raw food diet is more beneficial to humans than a cooked food diet. A raw food diet A cooked food diet

how to keep healthy
Nowadays, more and more people are concerned about their health. So it is necessary for us to know how to keep fit.
First of all, it is necessary for us to keep a balanced diet. We should eat more vegatables and fruit which contains lots of vitamins and less meat which contains a lof of fat. Besides, some people, especially girls, choose to go on a diet to look good, which actually has a bad influence on their health. Moreover, keeping a good state of mind is really good for our health. We should always take a positive attitude towards life. Last but not the least, make sure we take proper excercise every day. Running or walking, although simple, has a positive effect on our health.
In a word, there is a lot we can do to keep healthy. Let's take action to be healtheir.
