Many wine drinkers suffer from sulfite sensitivity, without even knowing it.
Allergic reactions to sulfites were proven REAL in 1973.
The FDA estimates that approximately 3 million Americans suffer - and this can develop at any time during your lifetime. Symptoms range from digestive (IBS, nausea, diarrhea), skin (rashes and hives) and respiratory (stuffy nose, wheezing, chest tightness) problems.
People with asthma seem to have a higher risk of experiencing a reaction to sulfites.
The World Health Organization (WHO) set the recommended daily allowance at 0.7 SO2/kg of body weight. Depending on your body weight, but half a bottle of wine will supply an amount of sulfites higher then the recommended daily allowance.
