If processed or fast food has been the bulk of your diet for a while, suddenly incorporating a ton of fruit into your diet might have you running to the bathroom more often. Fructose, the sugar found in fruit, can sometimes work as a laxative for your body because it stimulates your gut. Fructose could give you diarrhea if you take in more than 40 grams of it per day (per Harvard Medical School). Fruits higher in fructose are jackfruit, apples, grapes, raisins, and pears, according to MyFoodData. An apple has about 12 grams of fructose. Some fruits that are particularly low in fructose are avocados, apricots, raspberries, peaches, and blackberries. A cup of blackberries has 3.5 grams of fructose.
Eating fruit every day will give you a good enough amount of fiber to make it easier to poop. The soluble fiber in fruit dissolves in water to add bulk to your stool and ease diarrhea. The Institute of Medicine recommends 38 grams of fiber a day for men and 25 for women under 50 (via the Mayo Clinic). Fruits highest in fiber are passion fruit, avocado, raspberries, blackberries, and wild blueberries. A cup of raspberries provides 8 grams of fiber. You’ll want to avoid fruit juices because they have more fructose without the fiber.
