>>1081136its often caused by diet pills (they dont let you body digest fats, the result being shart) and many "low fat" foods, like low fat chips (they use some shitty chemical which has similar effect to low fat pills, therefore shart)
Fats are really important for your digestion. People get fat from carbohdrates mostly.
Anyway, I used to study shart phenomenon when the meme was a big deal, and I found out there is a shitload of shart related articles on american interweb, especially on women related sites. Interestingly enough, pretty much all of them merely offer an advice how to deal with shart (carry spare underpants, check your ass in a mirror from time to time, wash your ass on public toilet when it happens), but they never deal with the actual cause of the shart, not even mentioning that it can be caused by shitty food. As if shart was part and parcel of american life
