Our bones are a living tissue that constantly absorbs or releases calcium, as needed by the body. Osteoporosis arises when the body is unable to produce enough bone or reabsorbs too much, and this is greatly influenced by food.
Basically our bones are made up of calcium, proteins, including collagen, water and other minerals such as magnesium and phosphorus. Vitamins such as K2 and D help to fix calcium in the bone.
On the other hand, excess sugar and protein, refined foods, coffee, alcohol and salt can cause bone loss.
