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.
Background: Restricted carbohydrate diets remain among the most popular for weight loss and general health improvement. Recent evidence demonstrates that carbohydrate restricted diets are low in overall diet quality, yet their association with micronutrient inadequacy has not been well characterized at a population-level in adults in the United States.
Objective: 1) To evaluate the prevalence of not meeting daily micronutrient recommendations in US adults that met the Acceptable Macronutrient Distribution Ranges (AMDRs) and those who restricted carbohydrate to <45% energy, and 2) examine the effect of total fat and fat class on these results for the restricted carbohydrate group.
Design: This study utilized 24-hour recall data on food and nutrient intake from respondents in the National Health and Nutrition Examination Survey (NHANES) 2007-2018.
Participants/setting: This study included 15,029 respondents who were ≥20 y, had complete and reliable nutrient intake data, and were not pregnant or breastfeeding.
Main outcome measures: The main outcome was the prevalence of not meeting daily micronutrient recommendations based on Dietary Reference Intakes (DRIs).
Statistical analyses performed: The National Cancer Institute's usual intake methodology was used to estimate usual dietary intake and the prevalence of the US adult population not meeting the DRIs.
Results: Compared to participants that met the AMDRs, those that consumed restricted carbohydrate diets had greater prevalence of inadequacy (%
Conclusion: This study shows that there are different types of restricted carbohydrate diets that can be characterized by fat amount and class, each with their own association with micronutrient intake. This information can be used by clinicians to provide more targeted dietary counseling to their patients who restrict carbohydrates, depending on the amount and type of fat they consume.
