A growing body of work suggests an importance for Ca:Mg ratio. We calculated the change of Ca:Mg intake from foods over time in the United States of America. Method U.S. Department of Agriculture Food Surveys from 1977, 1985, 1994, 2001–2, 2003–4, and 2005–6 provided mean Ca, Mg and Kcal intake per day in adult age‐gender groups. (USDA Surveys before 1977 do not include Mg; Data for adults age 50+ were not reported until 1994; Defined age/gender groups changed slightly for age from survey to survey.) Survey means were used to calculate % changes in Ca, Mg, Kcal, and Ca:Mg intakes from food for 1977 to 2006 (1994 – 2006 for age 50+ yrs). Results Mean Ca daily intake rose in each age/gender group: a low of 21% for elderly males and a high of 77% for adult females. Mean Mg daily intakes rose in each adult age‐gender group, but to a lesser extent than Ca, from 3% for elderly males and a high of 28% in adult females. Caloric intakes rose in each age/gender group comparable to the rise in Mg rather than to the rise in Ca: 7% for elderly males and 26% for adult females. Conclusion Large rises in Ca intakes between 1977 and 2005–6 result in an apparent rising Ca:Mg from food, observed from 1977 to 2005–6 for each adult age‐gender group; 20 – 38% rise for adult women and 18 – 32% rise for adult men.
