Comparing Two Days of Dietary Intake in What We Eat in America (WWEIA), NHANES, 2013-2016.

The objective of this research is to compare the Day 1 and Day 2 dietary intakes of adults in What We Eat in America, National Health and Nutrition Examination Survey (WWEIA, NHANES) 2013-2016. Dietary recalls of males ( = 2599) and females ( = 2624) 20+ years who had both a Day 1 and Day 2 recall and reported their intake as usual on both days in WWEIA, NHANES 2013-2016 were examined. Mean (±SE) energy intake for males was 2425 ± 26 kcal for Day 1 and 2334 ± 32 kcal for Day 2 ( = 0.

Lithium pollution of a white dwarf records the accretion of an extrasolar planetesimal.

Tidal disruption and subsequent accretion of planetesimals by white dwarfs can reveal the elemental abundances of rocky bodies in exoplanetary systems. Those abundances provide information on the composition of the nebula from which the systems formed, which is analogous to how meteorite abundances inform our understanding of the early Solar System. We report the detection of lithium, sodium, potassium, and calcium in the atmosphere of the white dwarf Gaia DR2 4353607450860305024, which we ascribe to the accretion of a planetesimal.

Fruit and Vegetable Consumption of US Adults by Level of Variety, What We Eat in America, NHANES 2013-2016.

Background: Dietary guidance encourages consuming a variety of fruit and vegetables (FVs), which has been associated with higher FV intake and nutrient adequacy. Dietary intake of adults in the United States has not been described in the context of variety.

Objectives: The objective of this study was to describe FV consumption of adults in the United States by level of FV variety.
