One of the main requests we get here atTestyourintoleranceUSA.comis for people to see whether they are yeast intolerant or not. This is a surprisingly common intolerance which if gone undiagnosed, can cause a lot of pain to the sufferer.
The symptoms of a yeast intolerance can be extremely varied. If you have excess gas, feel tired, bloating, bad breath, psoriasis/eczema, mood swings or heartburn, these could all point to a yeast intolerance.
Most people get their sources of yeast from breads, and cakes, which include muffins, donuts and buns.
