Effects of 21 days of bed rest, with or without artificial gravity, on nutritional status of humans. J Appl Physiol 107: 54–62, 2009. First published December 12, 2008; doi: 10.1152/japplphysiol.91136.2008.—For the dietary intake data reported in Table 1, errors in nutrient intake determinations resulted from the food database entries for water consumption. Specifically, bottled water was included in the calculations of intake, but subjects were actually provided with filtered tap water. This affected intake of minerals, specifically calcium, magnesium, zinc, and sodium. After identifying the issue, we analyzed several water samples for mineral content, and have recalculated the intakes of these nutrients using the analyzed results. Although the changes were relatively small and did not affect the statistical findings or the conclusions in these papers, the correction, nonetheless, had an effect on the data. The corrected dietary intake data are shown in the table below (also see corrections in companion paper: Smith SM, Zwart SR, Heer MA, Baecker N, Evans HJ, Feiveson A, Shackelford LC, LeBlanc AD. J Appl Physiol 107: , 2009).Table 1.
