>>12170554>Whereas reduced calcium intake causes osteoporosis.No it doesn't. This claim misinterprets other studies, which show that indeed lower intakes result in less minerals in bones, but more collagen, which is the opposite of osteoporosis which starts with collagen falling apart. The decline in mineral density only follows that. In fact rodents fed "very low" calcium diets keep their teenage bones for life.
There basically no way to ever disprove old, mistaken knowledge with the current state of science once it's widely accepted as true. Since then, it's basically impossible to prove otherwise, because for example the 1mg copper intake is assumed to be a fact. While it is a well documented fact that copper deficiency makes the brain synapses get stuck (LTP), because we "know" the low intake is correct, the sticking of synapses must be a beneficial mechanism, and its lack must be a defect! And it's like that with everything.
