I'm having a hard time understanding where Paleolithic man got his calcium from. The only regular source of calcium for people today is in dairy, and since for the majority of our evolution we didn't have dairy it doesn't really make sense. I have read that Calcium isn't actually that important for bone health and it's actually vitamin D which is the key component. It seems like a lot of the "Calcium Importance" awareness is funded by the dairy and cereal industry. All you ever see on food advertisements these days are "a good source of calcium" or "fortified with calcium" etc etc. It seems that it would be very hard to get anywhere near the supposed RDA of calcium without dairy or fortified foods. Any thoughts on if calcium is that important, and if so where did Paleolithic man get his from?
No announcement yet.
