Vitamin D/Calcium Once Again Show Weight Loss Potential
An ongoing debate has been raging regarding the role of dairy products in weight management. A recent study has found new evidence to back the relationship between weight loss and diary.
The study was published in the September 2010 issue of the American Journal of Clinical Nutrition.
For the study researchers from the University of the Negev in Israel recruited 322 people with an average age of 52 and an average BMI of 31 kg/m2. People with a BMI over 30 kg/m2 are classified as obese.
At the start of the study, the researchers measured calcium and vitamin D levels. The participants were then followed for 2 years and data was collected on food intake and weight.
The data collected during the study showed that people who consumed higher levels of calcium and maintained higher blood levels of Vitamin D experienced weight management benefits.
Specifically, the researchers observed an 11.7 lb average weight loss among participants with the highest intakes of calcium (583 mg/day) and vitamin D(30.2 nanograms/day). Additionally, lower intakes of calcium (156 mg/day) and vitamin D (14.5 nanograms/day) were associated with an average weight loss of 7.3 lbs.
These findings come on the heels of a similar study published last month in the journal Nutrition and Metabolism which found that low levels of calcium may increase appetite and lead to weight gain.
Numerous studies have also found a link between vitamin D and weight loss. Previous research has also shown that vitamin D may play a role in reducing the risk of dementia and lowering the risk of heart disease and diabetes.
Approximately 1 billion people are vitamin D deficient worldwide and since our body becomes less efficient at synthesizing the vitamin as we age, those rates are only expected to increase. For this reason, taking a supplement or eating more foods fortified with the vitamin is often times a more reliant and safer option. Some foods that are often fortified with vitamin D are yogurt, milk, orange juice, cereals and margarine.
