I had a horrible, embarrasing smelly belch! It only happened about twice a week, but it smelled like sulpher,ie: rotton eggs! I checked the internet for what horrid diseaes I may have and found a recommendation for coconut oil. Two meals of scrambled eggs cooked in coconut oil cured me! Permanently! For the last 6 years I only use coconut or olive oil for cooking, not more "smelly burping" ever!
