Association between vitamin C intake and thyroid function among U.S. adults: a population-based study.

Background: Although some evidence suggests a role for vitamin C intake in thyroid diseases, the complex interplay between vitamin C intake and thyroid function remains incompletely understood. The objective of this study was to explore the relationship between vitamin C intake and serum thyroid function in the United States adults.

Methods: A total of 5,878 participants from the National Health and Nutrition Examination Survey (NHANES) between 2007 and 2012 were included in this study.

The relationship between dietary total flavonoids and thyroid function in U.S.adults, NHANES 2007-2010.

Background: Although small studies have shown that flavonoids can affect thyroid disease, few epidemiological studies have explored the relationship between dietary total flavonoids (TFs) intake and serum thyroid function. The aim of this research was to evaluate the relationship between TFs and serum thyroid function.

Methods: Our study included 4,949 adults from the National Health and Nutrition Examination Survey (NHANES) 2007-2010.
