I believe this is pretty normal…it shows that you have leaky gut. What kind of reaction did you get, can you describe the symptoms?
I personally would get the “leaky gut burn” feeling when I ate something that I’m allergic to…it feels similar to “indian rug burn.”
I would eat one spoonful per day for a few days and then stop, and then do this again until you can tolerate greek yogurt. It may take a few weeks/months to heal leaky gut.
The good thing is with leaky gut you can tell what you are allergic to easily. Later when your gut heals, it’ll become harder to determine whether something is affecting you negatively or not.
On a side note: I don’t think you are eating enough food. Try to add buckwheat to your diet or more items if possible. Try to eat 3-4 course meals.
