title: Dietary intake levels and food sources of magnesium and calcium for selected segments of the US population.
abstract: Dietary intake levels of magnesium and calcium, as well as magnesium/calcium ratios were assessed for adult females through use of the USDA's 1977/78 Nationwide Food Consumption Survey and 1985 Continuing Survey of Food Intake by Individuals. Results indicated that during the past 7 years the intake of calcium of adult females has increased significantly, while intake of magnesium has remained relatively constant. This has resulted in a greater imbalance of the intake ratio of these two nutrients by adult females. Adult females' principal food sources of magnesium were grain products, meat, poultry and fish, and vegetables, while their principal food sources of calcium were milk products and grain products.
