Onion: This is a well-known fact that eating raw onions leads to bad breath. But a few people simply love their salad with lot of onions. Eating a large amount of onion can make you stink real bad. While digesting raw onion, your body releases sulphurous gas which gets absorbed in your blood, making you perspire. Though it is good to eat raw onions during summers make sure you don’t eat excess of it or else you will smell like an onion yourself!
