Because sweets are greasy and have the function of helping dampness, dampness will lead to the formation of phlegm. Moreover, the spleen in the human body likes sugar best, and sweets are rich in sugar, so eating more will hurt the spleen. Once the spleen is damaged, the dampness will be more serious, so the phlegm will be more serious.
At the same time, most carbonated drinks, tea drinks, fruit juices, candies, etc. on the market now have high sugar content, and also contain pigments, essences and preservatives, which will stimulate the respiratory tract of the human body. This will also accelerate the production of phlegm.

Children with colds and coughs should not eat too much sweets;
According to the theory of traditional Chinese medicine, sweetness is sweet, which is earthy and corresponds to the spleen. Therefore, the spleen likes sweetness most, but it is also the source of phlegm. Excessive eating of sweetness will not only fail to nourish the spleen, but will turn into phlegm, leading to chest tightness, asthma and excessive phlegm, which will aggravate cough symptoms.
At the same time, sweetness helps heat, and children's cough is mostly caused by lung heat. Therefore, children suffering from wind-heat, phlegm-heat, phlegm-dampness cough or cough and asthma should not eat too much sweets.
