Can osteoporosis be cured if you consume foods that are high in calcium ?

Yes, but you must also eat a low or no animal protein diet. It's the meat that produces nitric and sulfuric acids when it is digested. The body must buffer that acid to remove it from the body, so it takes calcium from wherever it can get it. Like the bones and teeth. You can get all the protein your body needs from plants, especially legumes. I also recommend you go to youtube and search for DR BERG OSTEOPOROSIS. The question of calcium supplements being the cure may not be what you expected.

Not cured, no. Osteopenia, th he pre-osteoporosis condition is definitely sign that you should be lifting weights and otherwise strength training.

Stronger muscles require stronger bones, so both are built.

You need exercise too to build up bone strength.

Well, I don't know everything of the medical world but I know that milk and dairy products are responsible for osteoporosis and is to avoid! There are enough calcium in green food which are more body available like kale.

Once you have it, you have it but you can prevent developing more but calcium is not enough and is only 1 part of the process.

Not just consuming high calcium but lifestyle changes as in exercise and no smoking.

There is no cure for osteoporosis.
