The ADA recommends a level of fiber intake consistent with the Dietary Guidelines for Americans 2015–2020 (minimum of 14 g of fiber per 1,000 kcal). However, there is some evidence that higher intakes (daily consumption of 50g of fiber and higher), can result in small improvements in blood sugar levels. The ADA cautions that higher intakes may cause digestive issues such as “flatulence, bloating, and diarrhea.”
