If you just want to clean the intestines, I don't think apple vinegar is a good choice. According to the doctor in the Yangshengtang program, apple vinegar is actually a kind of sour drink made of apples, which has nothing to do with vinegar, and it is made of apples, which at most retains the nutrition of apples and has no more benefits. Moreover, apples themselves have dietary fiber, which is more conducive to cleaning the intestines. The so-called apple vinegar is just a promotion concept. If the stomach is not good, drinking on an empty stomach will aggravate the stomach discomfort. Of course, if you like the taste, you can drink it. Personally, I think this thing is quite expensive, so don't drink it. )
