Today we will have a look at the evidence linking leaky gut syndrome and coffee.
In this study: The impairment of gastroduodenal mucosal barrier by coffee the authors concluded that “coffee may damage gastroduodenal mucosa in habitual coffee drinkers. In a time period of 48 hours the gastroduodenal mucosa is capable of a significant regeneration.”
This is consistent with my experience – if I dring it along with some foods that can cross the intestinal epithelial barrier (gluten, lactose, fructose) triggered my symptoms.
It is surprising to see that the medical researchers fail to recognise this effect and allow for consumption of it in studies that involve leaky gut testinglike these:
Even more shocking is that if the people participating in the test did follow the doctor’s advice and did drink it they might have gotten their original condition worse.
Some sites link the mechanism of increasing intestinal permeability to caffeine content however I believe the mechanism is more complex than just that. I did have reaction to coffee and black tea but not to green tea and coke.
I chose to live without coffee and black tea. It definitely helps to keep my gut barrier in better shape. If you cannot quit at least do not eat wheat and milk within 48 hours after you had one.
