The Ecology of Humans (47-1) Calcium


Calcium is the basis of bones and teeth. 99% of the body’s calcium is stored there.

Deficiencies of calcium and vitamin D lead to osteoporosis: a disease of progressive bone mass and density loss, leading to effortless fractures. A dietary supplement of the two is recommended if dietary intake is questionable.

Foods high in calcium include seaweeds, beans (especially soy), kale, nuts and seeds (almonds, hazelnuts, pistachio, sesame), figs, quinoa, okra, rutabaga, and broccoli.
