1. Sugary foods
Eating too much sugar is a surefire way to trigger an upset stomach in most of us. Didn’t you ever binge on Halloween candy as a kid and then regret it when your stomach was talking to you during Math class? Sugar is especially connected to diarrhea. Apparently, sugar causes the gut to release water and electrolytes, which can make your stool loose.
Fructose, a type of sugar found naturally in fruit, is the worst offender when it comes to diarrhea. Fructose is what’s used to make high fructose corn syrup and it’s added to many foods and beverages. Harvard gastroenterologist Dr. Norton Greenberger says about 75 percent of people who eat 40 to 80 grams of fructose per day will end up with diarrhea.
