If you are self-conscious about the odor of your gas then eat more bananas. A team or researchers (I don’t envy their job) in Australia experimented with human feces to discover which foods make a person’s gas smell better.
What they found was cysteine – a component of meat, dairy and other types of protein- causes a seven-fold increase in the amount of hydrogen sulfide gas – which smells like rotten eggs – that was released by the gut bacteria in the feces.
But resistant starch, found in potatoes, bananas, legumes and fructans , which are found in wheat, artichokes and asparagus, reduced hydrogen sulfide by about 75%.
Another trick in reducing the smell of gas is to take ginger. This is available in capsule form.
