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.

Are People Consuming the Diets They Say They Are? Self-Reported vs Estimated Adherence to Low-Carbohydrate and Low-Fat Diets: National Health and Nutrition Examination Survey, 2007-2018

This study examined participants’ self-reported adherence to low-carbohydrate and low-fat diets compared with their estimated adherence using up to two 24-hour recalls.

Micronutrient Inadequacy Differs by Intake of Fat Amount and Class Among Adults That Consume a Restricted Carbohydrate Diet: National Health and Nutrition Examination Survey, 2007-2018

Restricted carbohydrate diets remain among the most popular for weight loss and general health improvement. However, recent evidence demonstrates that carbohydrate restricted diets are low in overall diet quality.

Micronutrient Intake from Three Popular Diet Patterns in the United States: Modeled Replacement of Foods Highest in Added Sugar and Sodium Using the National Health and Nutrition Examination Survey, 2005–2018

Modeled replacement of foods highest in added sugar led to more favorable changes in mean micronutrient intake compared to modeled replacement of foods highest in sodium.
