Is maltodextrin a low FODMAP food?

FODMAPs, also known as fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, are sugars not easily absorbed by the small intestine. Therefore, individuals who have been diagnosed with IBS (irritable bowel syndrome) may experience worsened gastrointestinal symptoms, such as constipation or diarrhea, when consuming high FODMAP foods (Veloso, n.d.). 

When reading a nutrition label, individuals on a low FODMAP diet are often puzzled by "maltodextrin", often found in the ingredients list of protein powders, sweetened drinks, candies, and desserts. Maltodextrin is a sweetener derived from starchy plants formed from glucose molecules (Jackson, n.d.). While maltodextrin is derived from wheat, a product not low in FODMAP, maltodextrin itself is low in FODMAP due to the way it is processed (Beyond Celiac, n.d.) and is considered appropriate in small amounts for those following the low FODMAP diet. 

What are the health benefits of maltodextrin?

The United States Department of Agriculture (USDA) classifies maltodextrin as "GRAS", or "Generally Recognized As Safe" for human consumption. Maltodextrin, however, has also been associated with increased blood sugar levels, weight gain, and poor gut health. On the other hand, maltodextrin can be an excellent fuel for athletes, aid in digestive health, and reduce the risk of developing colon cancer (Kloss, 2021).


This post aims to answer your questions regarding the low FODMAP diet and maltodextrin as a low FODMAP food.
