Obesity treatment could be one way to help larger women to improve their vitamin D levels.
According a recent study published in the American Journal of Clinical Nutrition, overweight or obese women who lose more than 15 per cent of their body weight see a significant increase in the circulating levels of vitamin D, a fat-soluble nutrient.
The research looked at 439 overweight-to-obese women, 70 per cent of whom had less-than-optimal levels of vitamin D.
Caitlin Mason, lead author of the paper, commented: "Since vitamin D is generally lower in persons with obesity, it is possible that low vitamin D could account, in part, for the link between obesity and diseases such as cancer, heart disease and diabetes.
"Determining whether weight loss helps change vitamin D status is important for understanding potential avenues for disease prevention."
Vitamin D is important for health because it promotes calcium absorption, protects older adults from osteoporosis and can influence cell growth.
