Few cries of old age are as widely feared as a broken hip. A calcium-poor diet,lack of exercise and in older women loss of estrogen can all contribute to osteoporosis which weakens bones. But those factors don't fully explain the 350,000 hip fractures each year in Australia researches say. Australian are washing away their bones in tide of acid made as their bodies try to metabolize a protein rich foods like meat and dairy.
Endocrinologist Deborah Sell-Meyer of Universty of Sydney divided more than 9,000 women 65 and older into five groups according to the overall acid load of their diet and found that women in the most acid group suffer hip fractures 3.7times more often than those in the least acidic group during the studies seven year period. There where studies also at the college of medicine in London and was over a 10 year period Dr Barzel has also shown that people worried about osteoporosis should replace some of there acid producing animal foods with more fruits and vegetables.
Looting the Bones
Our kidneys ordinarily regulate the acidity of our blood by dumping excess acid in the urine, but typical protein rich western diet over loads them. Protein contains sulfur which our liver turns it into sulfuric acid. The body has to neutralize some of it by looting the bones. There composed primarily of calcium phosphate and calcium carbonate which are excellent base for neutralizing acid. An acidic environment actully stimulates cells called osteoclasts which resorb bone mineral.over many years this process weakens the bones. Calcium rich foods can help make up for some of the loss but a growing number of studies now show that fruits and vegetables can help. They have showen that they produce acid neutralizing base. These studies have also shown the differences in the ratio of plant to animal food accounted for 70% of the variation in hip fracture rates.
