Vitamin D Makes Girls Big and Mean!
A new study in the Journal of Clinical Endocrinology & Metabolism claims vitamin D levels in adolescent girls are significantly associated with muscle power and force. Researchers recruited 99 inner-city girls from a multi-ethnic school between the ages of 12 and 14. And blood testing revealed 75% of the girls had low levels of vitamin D and the girls with higher levels performed much better on a jumping test used to measure strength; Nutraingredients reports.
Ironically, in October the American Academy of Pediatrics recommended doubling children’s daily intake of vitamin D to 400 units, replacing its 2003 recommendation of 200 units, based on claims that sufficient vitamin D may help reduce risk of cancer, heart disease and diabetes.
And previous reports show vitamin D deficiencies can cause back pain in older women and even increase the likelihood of c-sections.
