When we hear the word fluoride most of us think about its role in keeping our teeth healthy. It’s true that the main function of fluoride in the body is in the mineralisation of bones and teeth therefore, it is critical for healthy teeth and bones. This is why fluoride is now routinely added to most toothpastes. Fluoride is also present in soils, water supplies, plants and animals. Only a trace of fluoride is found in the body, but even at these tiny amounts, the crystalline deposits of fluoride result in larger and stronger bones and makes teeth more resistant to decay.
We have all heard the phrase ‘those bones need calcium’ and it is essential advice for all of us! An adequate intake of calcium is one of a number of factors important for acquiring bone mass and attaining peak bone mass. Diets containing insufficient amounts of calcium may lead to lower bone mineral density, which may have implications for bone health, notably risk of osteoporosis later in life. Our bones are gaining and losing minerals continuously in an ongoing process of remodeling. Calcium forms crystals on a matrix of the protein collagen. This process is called mineralization. During mineralization, as the crystals become denser, they give strength and rigidity to the bones. Most people achieve a peak bone mass by their late 20s, and dense bones best protect against age-related bone loss and fractures.
