>> The actual problem is that less sugar enters the blood stream than is tasted. But tasted where ? do we have any knowledge what happens when the tongue measures one level of sweetness and the gut another ? And don't the case of the gastric bypass implies that if the gut senses less sugar(either because of less sensors, or because of less sugar) , we get positive results ? >> no substitute for eating healthy.. than…
The taste buds in your gut are on the same side of the gut as the food. So your gut can taste sugars that pass through you without being absorbed. Given that fact, we can speculate that sweet things that aren't absorbed might be more harmful than ones that are absorbed, as they have a chance to activate taste buds all the way through the gut as they go past, rather than just the earlier ones.
Hopefully the guys at DouxMatok are think about this and optimizing their sweetener to quickly dissolve in the gut.
And sure, this definetly needs full animal testing before claiming things about it.
