WebMay 5, 2024 · Blood calcium (Ca 2+ ) levels are tightly regulated by PTH, vitamin D, and calcitonin. Through these two opposing pathways—PTH and vitamin D for raising blood calcium and calcitonin for lowering blood calcium—the body can very effectively maintain blood calcium homeostasis. Not all the calcium in the diet can be readily absorbed from the gut. The calcium that is most readily absorbed is found in dairy products (72%), vegetables (7%), grains (5%), legumes (4%), fruit (3%), protein (3%). The calcium contained in vegetable matter is often complexed with phytates, oxalates, citrate and other organic acids, such as the long-chained fatty acids (e.g. palmitic acid), with which calcium binds to form insoluble calcium soaps.
