Fruit is generally considered a healthy food that offers many health benefits in addition to providing natural sugars. It typically doesn’t cause immediate digestive discomfort, but excessive consumption of fruit can lead to increased stomach acid and gas production. Fruit oligosaccharides are more slowly absorbed than other carbohydrates are, causing the large amount of undigested carbohydrate molecules to get fermented by colonic bacteria which can lead to discomfort including bloating, flatulence, nausea, cramps, belching or just feeling very full.
