You can eat bananas, but you can't drink yogurt on an empty stomach. Don't drink yogurt on an empty stomach, because lactic acid bacteria in yogurt are easily killed by stomach acid on an empty stomach, so the health care function of yogurt will be weakened. Bananas are rich in sugar and fiber, which is beneficial to digestion and laxation, but eating bananas on an empty stomach is not healthy, because there is almost no digestible food in the gastrointestinal tract on an empty stomach.

Extended data:

It is best not to eat yogurt when you are hungry, because the acidity in the stomach is high (pH 2) on an empty stomach, lactic acid bacteria are easily killed by gastric acid, and the health care function is weakened. About 2 hours after a meal, the gastric juice is diluted, and the pH value in the stomach (pH value rises to 3 ~ 5) is most suitable for the growth of lactic acid bacteria (pH value suitable for the growth of lactic acid bacteria is above 5.4). For other people with normal gastrointestinal function and no diarrhea, they can drink it before and after meals as long as they are not particularly hungry.
