Calcium: Non-animal sources

Excerpt from my first book ‘Elixir: How To Use Food As Medicine’.

In the Western world we have a high intake of cows dairy and a high incidence of osteoporosis, so perhaps we need alternative sources of calcium that contain magnesium to help the calcium get into the bones, and without all the additives that cows milk contains.
It has been shown that animal protein causes the body to excrete calcium more quickly than plant protein. Coffee also has this effect, along with an excess of unfermented soy products such as milk and tofu. Rich sources of calcium include leafy green vegetables, quinoa, dried fruit, nuts and seeds, molasses, sea vegetables and tahini. Parsley and other herbs are also good sources.
Green plants are higher in calcium than any other food. However, beet greens, plums, cranberry, silver beet and unhulled tahini are high in oxalic acid, which inhibits calcium absorption.
