Comments P.158 right column top paragraph: "Calcium intake from food in the United States has increased over time relative to magnesium intake, according to an analysis [primary source] of USDA surveys since 1977 [refs 80–86]. Between the USDA’s 1977 and 2007–2008 surveys, the mean magnesium intake in young adults aged 19–34 years rose by 11–16%, while mean calcium intake in the same group rose by 32–43% (Figure 2). Similarly, the mean magnesium intake for adults aged 35–50 years rose by 12–18%, while the mean calcium intake for this group rose by 48–64% (Figure 3). Adults aged ≥50 years showed 11–40% increases in calcium intake from food, with increases in magnesium intake from food at -2% to +16% over the 13 years between 1994–1995 and 2007–2008 (data not shown). For all age-gender groups in this analysis, the percent increase in mean magnesium intakes compared closely with the percent increase in mean energy intakes, while the percent increase in mean calcium intakes was substantially higher (Figures 2 and 3), this suggests the increasing calcium-to-magnesium ratio comes from higher calcium intake via food selections, the rising calcium content of food, or both."
