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.

Research Focus Areas:

  • Advance scientific evidence and research tools to further understanding of how fiber relates to human health outcomes.
  • Characterize nutrient intakes and overall diet quality of various carbohydrate restricted or modified diet patterns.
  • Clarify and communicate research tools examining causal relationships between energy containing food/ingredients and body composition.
  • Promote informed decision-making on food choices - focused on carbohydrate quality.

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.

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

Nutrition Reviews, 2022

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.

Scoping Review and Evidence Map on the Relationship Between Exposure to Dietary Sweetness and Body Weight-Related Outcomes In Adults

Advances in Nutrition, 2022

A scoping review and evidence map were completed to characterize the research investigating dietary sweetness and body weight. The aim is to identify and map studies that investigate total dietary sweetness, sweet food/beverage, sugar, or sweetener intake and body weight-related outcomes.
