Too much salt can be bad for bones
If you're a postmenopausal woman, be sure to track your salt intake. A new study from the University of Shimane in Japan has found that too much sodium in your diet can increase the risk of bone fractures. The research determined that older women who consumed the most amount of sodium had nearly four times the risk of suffering from a bone fracture, regardless of bone density, which is usually tied to an increased risk of bone fracture. The research concludes that sodium intake adds to bone fragility, which can lead to a higher likelihood of bone fractures everywhere other than your back.
This study observed 213 postmenopausal women with an average age of 62 who had undergone osteoporosis screenings. Bone density scans were taken, and the women answered a questionnaire about their diets. Blood work was also taken to test markers of bone metabolism, and to rule out medical conditions that could increase fracture risk. The scientists controlled for other factors that could influence bone fractures, including BMI, age, bone mineral density, calcium and vitamin D intake, and vitamin D blood levels.
Among those tested, the average daily sodium intake was 5,211 mg, with the highest levels reaching as high as 7,561 mg per day. Those who ate the most sodium were 4.1 times more likely to suffer a bone fracture.
The Centers for Disease Control (CDC) recommends that Americans consume no more than 2,300 mg of sodium per day and that certain populations – including older people – should consider cutting back to 1,500 mg per day. That’s significantly lower than what the study found most people actually consume.
