Vinegar. Vinegar can cause osteoporosis by inhibiting calcium synthesis in the bones. Drink milk! However, naturally fermented apple vinegar (cider) has healing properties associated with beta-carotene, pectins, potassium, sodium, magnesium, calcium, phosphorous, chlorine, sulphur, iron, and fluorine.
What have you heard? Use of vinegar has been reported to assist with calcium absorption and thus help with osteoporosis... It can affect the kidneys if too much is taken. Any to excess if foolish.
