Let me tell you, their food is similar. It happened that I also ate this dietary fiber powder. This thing has nothing to do with before and after meals. All you have to do is pour a bag of water or drink, tea, juice or soup and mix well. But remember, those drinks with steam won't do. One more reminder, it is best to pour it into hot drinks or water, because I personally sometimes pour it directly into ice water when I am lazy, and as a result, the taste of this tea becomes very pink. How can I put it? Think about it, powdery things are difficult to melt in cold water or warm water, and they will feel powdery and uncomfortable to drink.
