Changes in DNA methylation patterns during critical development periods are associated with disease outcomes and are associated with changes in nutritional status in pregnancy. The long-term impact of periconceptional folic acid supplementation on DNA methylation patterns is unknown.

- Dietary supplement (DS) use in the U.S. rose from 50% in 2007 to 56% in 2018, with micronutrient-containing (MN) supplements also seeing an increase from 46% to 49%.
- The study utilized a combination of data collection methods from NHANES to analyze trends across different demographics, revealing significant growth in DS usage among various groups, particularly men, non-Hispanic blacks and Hispanics, and low-income adults.
- Despite the overall increase in DS use, multivitamin-mineral usage decreased substantially, while individual nutrient supplements gained popularity, reflecting changing preferences in dietary supplementation.
Measurement Error Affecting Web- and Paper-Based Dietary Assessment Instruments: Insights From the Multi-Cohort Eating and Activity Study for Understanding Reporting Error.

Few biomarker-based validation studies have examined error in online self-report dietary assessment instruments, and food records (FRs) have been considered less than food frequency questionnaires (FFQs) and 24-hour recalls (24HRs). We investigated measurement error in online and paper-based FFQs, online 24HRs, and paper-based FRs in 3 samples drawn primarily from 3 cohorts, comprising 1,393 women and 1,455 men aged 45-86 years. Data collection occurred from January 2011 to October 2013.

A nutrient-based approach that captures total intake inclusive of DS can strengthen exposure assessment.
Objectives: We examined the construct and criterion validity of the Total Nutrient Index (TNI) among US adults (≥19 years; nonpregnant or lactating).
