In researching sulphites, I found the following on this website: sulfites.org/sulfite-allerg...
Possible Symptoms and Diseases Related to Sulfites
Chronic fatigue syndrome
Candida and other fungal infections
Irritable bowel syndrome (IBS)
Tooth pain and sore gums
Vaginal yeast infections
Apparently, sometimes it takes certain concentrations to trigger a problem. Heart palpitations is on the list.
There is a list of foods that can have sulphites. sulfites.org/sulfite-foods/ Too bad eating is necessary since not eating seems about the only way to entirely avoid sulphites.
