Eating Whole-fat Yogurt Is Associated with Lower Obesity in an Elderly Population

Eating Whole-fat Yogurt Is Associated with Lower Obesity in an Elderly Population

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. Read More...

Dairy Products Could Significantly Increase Satiety

Dairy Products Could Significantly Increase Satiety

Obesity is a major public health issue—with no easy remedies. One potential solution involves consuming foods that increase satiety, thus reducing appetite for later meals and helping with weight loss. So far, a variety of foods have been shown to affect satiety, including soda, fruit drinks, and milk. Researchers have been particularly interested in using dairy for this purpose, but studies on how dairy products influence appetite have had conflicting results. Read More...

Getting the Balance Right

Getting the Balance Right

Once described as an epidemic, obesity has now reached pandemic status with an estimated 600 million obese adults worldwide, and an additional 1.4 billion that are overweight. The cause of the pandemic is known—people consuming more energy (calories) than they expend—so it would seem that the solution would be to simply eat less. But a team of nutritional ecologists believes that cutting calories will not solve anything, because it ignores some basic tenets of human (and animal) biology. Using data from fruit flies, mice, birds, fish, monkeys, and humans, Raubenheimer, Simpson and their colleagues demonstrate a seemingly universal law of animal nutrition: a predominant appetite for protein. They propose that the human need to meet a fixed daily protein target leads to weight gain through the overconsumption of low protein foods that have come to dominate the Western diet. Rather than advocating for a high protein diet that eschews carbohydrates, they emphasize a balance of macronutrients for optimal health. Can dairy help strike this balance? Whole-food sources of protein that are easy to access, like dairy, can help balance out those beloved low-protein, high-carbohydrate processed foods and keep energy consumption in check. Read More...
