Dietotherapy has scientific basis. Dietotherapy is because food also contains ingredients that can treat diseases, but it is less. Therefore, dietotherapy can treat some minor illnesses. If it is serious, you still need medication. Dietotherapy is not a medical term, but mainly a folk concept, which is mixed with traditional customs, cultural concepts and commercial symbols. Although the treatment of diseases can not be separated from the support of nutrition, the importance of nutrition is the same as that of breathing. We can't cure diseases by breathing. Similarly, treatment cannot be separated from nutrition, but it cannot be treated by nutrition.
