Preventing osteoporosis with excellent nutrition

Bone health is directly linked to nutrition. Certain foods promote breakdown of bone and osteoporosis. Other foods, such as fruits and vegetables, supply your body with the nutrients necessary to build and maintain healthy, strong bones and prevent osteoporosis.

A number of substances in foods promote the loss of calcium in the urine, which leads to bone loss and osteoporosis. The foods we should avoid to protect the health of our bones include animal products, salt, soda, and caffeinated beverages. Salt and caffeine are known contributors to calcium loss. Also, high caffeine intake is associated with increased bone loss and osteoporotic fractures. Animal protein and other high protein foods leave acidic residues in the blood, and the body responds by dissolving bone to release basic calcium salts to neutralize the acid. This results in loss of calcium in the urine. Many studies have found animal protein intake to be associated with low bone mass. In contrast, plant protein intake is associated with decreased hip fractures in the elderly. Natural plant foods do not leave an acidic residue in the blood or promote urinary calcium excretion. Soda, including diet and decaffeinated soda, is associated with bone loss. Soda consumption increases parathyroid hormone (PTH) in the blood, which increases blood calcium concentrations by stimulating bone breakdown. This increased blood calcium is then excreted in the urine.
