Drinking yogurt and cola together may cause diarrhea. Yogurt has a higher content of probiotics, which has the effect of promoting gastrointestinal peristalsis and facilitating the digestion of nutrients. However, cola contains more carbon dioxide and is a carbonated beverage, which has a certain effect on the function of the gastrointestinal tract and gastrointestinal peristalsis. So if yogurt and cola are put together and drunk, they may stimulate the gastric mucosa and symptoms such as bloating and diarrhea may occur. In addition, there are a lot of vitamins and calcium in yogurt, and after fermentation, yogurt can promote the absorption of calcium, phosphorus and other substances in the human body. So moderate consumption of yogurt can play a role in promoting intestinal peristalsis and maintaining the balance of gastrointestinal flora. However, drinking yogurt and cola together is not conducive to the body’s absorption of nutrients, and may destroy the beneficial components of yogurt. It is not recommended to drink yogurt and cola together to avoid diarrhea and other uncomfortable symptoms, if diarrhea still exists after avoiding the above dietary factors, it is recommended to consult a doctor in a timely manner, under the guidance of a professional physician to clarify the cause of the disease.
