Frozen yogurt, like ordinary yogurt, can promote gastrointestinal digestion if eaten regularly. Frozen yogurt contains many beneficial bacteria, which can promote the gastrointestinal tract to produce more digestive enzymes, so it can promote appetite. Regular use of frozen yogurt can also play a role in slimming, because frozen yogurt has a good satiety, which can not only slim down, but also promote the body to absorb nutrients. Some people freeze yogurt into ice and find that the thawed yogurt has the phenomenon of water-milk stratification, which is a bit like bean curd residue and looks bad, but such yogurt is actually edible. This phenomenon is a normal phenomenon that yogurt contains more water, which leads to inconsistent freezing point when frozen, but it does not affect the efficacy of eating yogurt and will not produce substances harmful to human body. As long as yogurt is still within the shelf life, you can safely drink it.
