Do foods cause rashes?
Food Facts
This is a question we typically get asked when considering why babies get diaper rash. Parents often worry that foods that are high in citric acid may be problematic. There is no scientific data that points to specific types of foods causing diaper rash (or any other kind of rash) unless the food in question causes an allergic reaction. However, if you (or your baby) has never tried the food before, you may experience loose stools (diarrhea) which can cause irritation and rash.
