Will oatmeal make you fart if eaten alot?

Farting is caused by inadequate digestion. Undigested food rots in your gut, producing gases and odors depending on what you eat and what organisms live in your gut. For instance you can eat yogurt every day and the yogurt bacteria will crowd out all other organisms so you never have farts.

You should study some books about nutrition so you know a few things like this.
