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.

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.

Perspective: Assessing Tolerance to Nondigestible Carbohydrate Consumption

Advances in Nutrition, 2022

Non-Digestible Carbohydrates provide functional attributes to processed foods, including sugar or fat replacers, thickening agents, and bulking agents. Additionally, NDCs are incorporated into processed foods to increase their fiber content. Although consumption of NDCs can benefit health and contribute functional characteristics to foods, they can cause gastrointestinal symptoms, such as bloating. As gastrointestinal symptoms negatively affect consumer well-being and their acceptance of foods containing NDC ingredients, it is crucial to consider tolerance when designing food products and testing their physiological health benefits in clinical trials.

Gastrointestinal Effects and Tolerance of Nondigestible Carbohydrate Consumption

Advances in Nutrition, 2022

Guidance on tolerable intake levels of different non-digestible carbohydrates is needed because overconsumption can lead to undesirable gastrointestinal side effects, further widening the gap between actual and suggested fiber intake levels. In this review, we synthesize the literature on gastrointestinal effects of NDCs that the FDA accepts as dietary fibers and present tolerable intake dose recommendations for their consumption.

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.
