Eating Whole-fat Yogurt Is Associated with Lower Obesity in an Elderly Populationby Sandeep Ravindran in SPLASH! milk science update: September 2016 Researchers have previously studied the association between yogurt consumption and obesity, but so far the results have been inconclusive, and few studies have compared the effects of low-fat and whole-fat yogurt. A new study finds that consumption of whole-fat yogurt but not low-fat yogurt is significantly associated with a decreased waist circumference and a higher probability of reducing abdominal obesity in an elderly population. The researchers suggest that the results may be due to some inherent benefit of the fat in whole fat yogurt, or because low-fat yogurt often contains more sugar. The researchers conclude that whole-fat yogurt may offer some benefits for managing obesity in an elderly population but point out that consuming any type of yogurt is expected to have positive effects on health.
For those on a diet, it might be natural to reach for low-fat rather than whole-fat yogurt. But the results of a new study might make that decision a little more complicated, at least in some populations. In the study, Carmen Sayón-Orea and her colleagues at the University of Navarra found that eating whole-fat yogurt was associated with a decrease in waist circumference and a greater probability of reducing abdominal obesity in an elderly population at high cardiovascular risk . The researchers didn’t find a similar association with low-fat or total yogurt consumption.
Researchers have previously studied the associations between yogurt consumption and obesity, but the results have been inconclusive [2–5]. In addition, few studies have looked at the effect of low-fat versus whole-fat yogurt. “We wanted to clarify the role of these kind of yogurts,” writes Sayón-Orea in an email.
Sayón-Orea and her colleagues previously found that for young, healthy individuals consuming a lot of whole-fat yogurt was associated with a lower risk of becoming overweight or obese . “We decided to replicate our research in an elderly population,” she writes.
