White chocolate contains milk solids, sugar, cocoa butter, and flavorings, but lacks the cocoa solids found in dark and milk chocolates. Some individuals might experience discomfort or even sickness due to a few reasons. It could be a lactose intolerance, as white chocolate contains milk solids. For some, it may also be due to the high sugar content causing an upset stomach. Personally, I’ve noticed that consuming too much white chocolate sometimes upsets my stomach due to its richness. It’s essential to listen to your body and moderate your intake. If you notice recurring discomfort, consider consulting a healthcare professional for personalized advice.
