Yogurt with dragon fruit has the potential to cause diarrhea. Yogurt is a milk product produced by pasteurizing and then adding beneficial bacteria to continue fermentation. Yogurt contains a lot of protein, calcium and other nutrients, followed by the addition of probiotics. Therefore, yogurt can supplement protein and calcium, but also can regulate gastrointestinal function, promote intestinal motility and health. Dragon fruit contains protein, dietary fiber, vitamins and other nutrients. Among them, dietary fiber can promote intestinal peristalsis and accelerate fecal discharge. Both have components that promote intestinal peristalsis, so yogurt with dragon fruit may be diluted. It is recommended that although yogurt and dragon fruit contain a lot of nutrients, conducive to health, but still need to eat in moderation to avoid excessive consumption of discomfort.
