: Yogurt contains calcium , protein , riboflavin , vitamin B6 and vitamin B16. If you eat water and yoghurt together at this time, then the effect of water on the molecules of the component of yoghurt will mix with the water molecule and disrupt the action of the enzyme. As a result, many people have digestive problems after drinking yogurt and drinking water. You should drink water after maximum 10 minutes and minimum 5 minutes after eating yogurt. That is better.
