Gut carbs sensors cravings
Sources:
The gut has specific sensor cells that detect carbohydrates and play a crucial role in cravings for sweet foods. explains that these sensors in the gut recognize the presence of sugar and signal this to the brain via the vagus nerve, ultimately triggering dopamine release, which results in cravings for more sugar 1.
Notably, these gut sensors can distinguish between caloric sugars and non-caloric sweeteners. Studies reveal that artificial sweeteners fail to activate the gut-brain axis because the gut sensors specifically recognize glucose, not artificial sweeteners. This inability to satisfy the sugar craving at the gut level is why artificial sweeteners often fail to curb sugar cravings 2 3.
Furthermore, has shown that manipulating these gut cells can even make mice crave non-caloric sweeteners as if they were sugar. This insight highlights the powerful role gut sensors play in our cravings and how they might be targeted to manage these desires better 4.
