3 Aluminum mixes with calcium and weakens bones
High aluminum levels in the body alter bone mineralization, matrix formation, as well as parathyroid and bone cell activity. Ironically, one of the most common signs of excessive aluminum accumulation is hypocalcaemia or high calcium levels in the blood.
The reason for this happening is because aluminum in the body restricts calcium deposits in bone thus causing an increase of calcium in the blood. This in turn depresses PTH secretion which is secreted by the Parathyroid hormone. The chronic aluminum toxicity which then builds up retards bone mineralization which then causes osteoporosis.
