Please don't be superstitious about any advertisements for health products. They are all misleading and deceptive. The so-called high-tech extraction of dietary fiber and vitamins is just to separate the skin and pulp of a good fruit, extract them separately, and finally become dietary fiber and vitamins respectively, and then you have to pay a high price to buy things that you could have bought for only a few dollars! It is also less and more simple than the nutrition you can absorb by eating a fresh fruit directly!
