A new Australian study has found that reducing the amount of salt in your diet can help your bone health.
Thursday, April 29th, 2010A new Australian study has found that reducing the amount of salt in your diet can help your bone health.
The study was conducted over 12 weeks with middle aged women from 45 -75 by reducing the sodium (salt) in their diets from 9.7gms to 6.5gms and monitoring the results from their urine. A second group was given a high carbohydrate, low fat diet with lower salt intakes.
It was found that the the amount of calcium leached from the body and excreted was less in the target group with blood pressure decreasing from 146/91 to 141/88 mmHg and sodium (salt) decreasing by 26%, while the high carb, low fat diet reported more calcium being leeched from the body than the purely low salt intake group..
The World Health Organisation recommends a daily intake of 5mg, over half the amount of salt that is consumed by the western world currently at 10-12g per person.
The other benefit of reduced calcium loss in the benefit is for those women at risk of getting osteoporosis, by taking early preventative action the risks will be reduced.
