Foods high in Calcium, Ca
Calcium is the mineral your body stores in the greatest quantity, almost entirely as the structural framework of bone and teeth. Because the body cannot make calcium on its own, everything it uses comes from food, and it draws on stored bone calcium whenever dietary intake falls short, which is part of why sustained low intake is linked over time to conditions like osteoporosis. Growing children and teenagers, whose skeletons are still accumulating bone mass, and women past menopause, whose needs rise along with bone loss risk, are among the groups whose requirements are set higher than the typical adult figure. Pregnant and breastfeeding teenagers also have elevated needs compared with adult women in the same situation. The list below ranks foods and ingredients by measured calcium per the amount analyzed, so some of the very top entries are dehydrated herbs, spices, and baking ingredients that are concentrated by drying or formulation rather than foods eaten in large quantities day to day. For building an everyday eating pattern around calcium, dairy products, canned fish eaten with their soft bones, calcium-set tofu, certain leafy greens, and calcium-fortified foods are generally the more practical, realistic contributors, even when they don't sit at the very top of a per-unit ranking.
Adults need about 700.0000 MG/day (age 1-3 years) — NIH ODS Calcium — Health Professional Fact Sheet (corroborated).
