Vitamin D Linked with Obesity, Diabetes
The researchers tested 411 obese children between six and sixteen years old for 25-hydroxyvitamin D (indicates available vitamin D) in the blood, along with insulin resistance, fasting glucose and insulin levels. They compared these results with 87 control children subjects, who were the same age but not overweight.
They found that 92% of the obese subjects were deficient in vitamin D, with 50% critically low (below 50 mmol/liter). Among the non-obese subjects, only 22% were critically low in vitamin D.
They also found that low vitamin D levels were associated with higher soda consumption, refined juice consumption and missing breakfast.
Furthermore, they discovered that the type 2 diabetes was more common among those with low vitamin D levels in their bloodstream.
The researchers concluded that, “Vitamin D deficiency is common in children in this southern United States location and is significantly more prevalent in obese children. Lower 25(OH)D level is associated with risk factors for type 2 diabetes in obese children.”
While food sources of vitamin D are limited, the easiest way to achieve higher vitamin D levels is through healthy sun exposure.

Case Adams is a California Naturopath with a PhD in Natural Health Sciences, and Board Certified Alternative Medicine Practitioner. He has authored 26 books on natural healing strategies. “My journey into writing about alternative medicine began about 9:30 one evening after I finished with a patient at the clinic I practiced at over a decade ago. I had just spent the last two hours explaining how diet, sleep and other lifestyle choices create health problems and how changes in these, along with certain herbal medicines and other natural strategies can radically yet safely turn our health around. As I drove home that night, I realized this knowledge should be available to more people. So I began writing about health with a mission to reach those who desperately need this information. The strategies in my books and articles are backed by scientific evidence along with wisdom handed down through traditional medicines for thousands of years.” Case connects with nature by surfing, hiking, running, biking and according to Dad, being a total beach bum.
