Calcium is the most abundant mineral in the body and between birth and puberty a child’s bone structure increases 7-fold. About 11% of men and 27% of women aged 60+ have osteoporosis with the lifetime risk of having an osteoporotic fracture after 50 years of age is 42% for women and 26% for men. There are 20,000 hip fractures in Australia every single year. Risk factors for osteoporosis include family history, being female smoking, lack of exercise and depression.
Osteoporosis is a silent disease and the first sign is usually a fracture. Ensuring the right nutrition is vital here. Did you know that:
One cup of coffee takes 40mg of calcium from bones?
Soft drinks are high in phosphorous which binds to calcium making it unavailable for use
Sugar decreases calcium absorption
Salt increase calcium excretion. For each 6grams of salt, 24-40mg of calcium is excreted into the urine
Alcohol inhibits dietary calcium absorption
Alkaline diets, which are rich in fruits, vegetables, pulses and legumes, are associated with good bone health. The role of vitamin D in bone health is critical as it increases bone mineral density. Australia has a widespread vitamin D deficiency and research shows that the lower your vitamin D, the higher your risk for osteoporosis.
What do I need to do?
Every day you need to consume 1200mg calcium and 800 IU of vitamin D. In combination with a calcium rich diet, you need to be doing weight bearing exercise. Choose from the list of calcium rich foods below and eat them on a regular basis.
