I asked this question on the official live broadcast, and the answer given by the anchor was "nothing". The components of white kidney beans can effectively resist sugar and carbohydrates before eating, so they can play a pre-control role. But I think it's better to eat after meals, because stomach acid is stronger on an empty stomach before meals? It is not conducive to the survival of prebiotics and probiotics ingested in the body. After a meal, it can reduce irritation, make the nutrients absorbed in the body slowly absorbed in the stomach and help digestion, so I suggest eating after a meal ~
