These pretty looking peppers have a vibrant appearance and taste absolutely delish with anything. But, it is best to avoid munching on these during the monsoon season. The main reason behind this avoidance is that bell peppers when chewed convert glucosinolates in them into isothiocyanates. In layman terms, bell peppers may cause diarrhea, vomiting, nausea and breathing problems in some. Therefore, it is better not to eat them at all during the drizzle.
