The Carbohydrates Committee addresses outstanding scientific issues through discovery, research tools and translational messaging related to how carbohydrate-rich foods, food components and formulations are associated with consumption behavior, diet quality and health outcomes.

Why is this research important?

Carbohydrates are an important source of energy and nutrients in the food supply. The committee focuses its work on understanding sugar, fiber, and carbohydrate quality as they relate to human health.

Rare Sugars and their Health Effects in Humans: A Systematic Review and Narrative Synthesis of the Evidence from Human Trials

Nutrition Reviews, 2021

Little is known about the unique physiological and cardiometabolic effects of rare sugars in humans. The objective of this study was to conduct a systematic review and synthesis of controlled intervention studies of rare sugars in humans, using PRISMA guidelines.

Development and Validation of Test for ‘Leaky Gut’ Small Intestinal and Colonic Permeability Using Sugars in Healthy Adults

Gastroenterology, 2021

Oral monosaccharides and disaccharides are used to measure in vivo human gut permeability through urinary excretion. Baseline 12C-mannitol excretion precludes its use; 13C-mannitol is the preferred probe for small intestinal permeability.

The purpose of this workshop was to facilitate an exchange of scientific and technical information with stakeholders involved in selecting science-based indices to use in communicating physiologic effects of carbohydrates in foods.


The outcomes of this workshop are scientifically based summary statements for use in programs that communicate about carbohydrate quality, with the intent that future programs harmonize approaches by authoritative organizations throughout North America.
