Eating sweets in moderation will not harm the spleen and stomach, but excessive consumption of sweets will aggravate the burden on the spleen and stomach and produce dampness, which will cause some harm to the spleen and stomach. Sweets are sweet foods that enter the spleen, which has the role of transporting and transforming water and grains. If the spleen and stomach are weak and a large number of sweets are eaten, they will easily stimulate the spleen and stomach and increase the burden on the spleen and stomach, which will cause damage to the spleen and stomach and at the same time may cause phlegm-dampness, phlegm turbidity, and diarrhea, among other symptoms. If you have a weak spleen and stomach, you should avoid spicy and stimulating foods, fatty and sweet foods, and foods that are not easy to digest, such as chili peppers, garlic, fried foods, and foods high in sugar, etc. When the symptoms are serious, it is recommended that you seek medical attention in a timely manner.
