HI Rachel, yes it is possible you have released metals in your cleansing! Killing off yeast/parsites etc often release metals in the process. This happened to me when I used an a herbal antifungal mixture for yeast.

So perhaps now that things are more exposed, using sulfur foods is more readily stirring it up.

I would be careful about buying into the allergy thing "too" much because many foods create healing symptoms and stir up mercury and can make you feel intolerant of them. The main foods that are a problem are the sugars and grains because they feed organisms.

Foods such as onions, garlic and eggs could create "allergy" type symptoms usually because of their effect on pathogens and/or metals. I've had this myself many times in my life and thought I had developed an allergy, but it wasn't. It was just the stages I was going through and reactions to sulfur, depending what was going on inside of me (and what may have been released).

There have been times I could barely tolerate eggs and onions (I never really ate garlic) and had to lessen or stop eating them. Even cabbage brought on symptoms. But later I coudl eat them again in abundance. Many healing foods like butter can also bring on healing symptoms. But butter does not tend to stir up mercury, however it is a healing food and can still create symptoms for other reasons.

Don't be afraid of healing reactions, though they can feel like allergies. But don't push yourself too much either at the sametime. I just did a bit of it every now and again.
