With the development of multiple novel technologies, but also with the completion of studies started years ago, a great many studies are being reopened or retaken into consideration. And this happens more often than you’d think, with something turning out to be the opposite of what we thought on a weekly basis.
And this can happen as a result of new technology helping us perform better tests, or simply older studies being finally completed. For example, thanks to a couple of long-running studies, we have a new viewpoint on dairy – contrary to popular opinion, full-fat dairy products are healthier than low-fat ones.
While one study focused on diabetes and the other focused on gaining weight, in both cases it turned out that full-fat dairy products are healthier than low-fat ones. There are multiple reasons for this, depending on each case, so let’s dive into the studies and see for ourselves.
The first one was a meta-analysis based on the long-running Nurses’ Health and Health Professionals Follow-Up Study. With the participants followed for decades, the researchers got enough information to conclude that when compared to people with the lowest amount of dairy fat in their blood, those with the highest amount had a forty percent lower chance of developing diabetes.
Meanwhile, the second study looked at the relationship between high-fat dairy consumption and the chances of becoming overweight or obese. The meta-analysis was focused on some eight thousand participants in the long-running Women’s Health Study. Followed for over a decade, the participants were asked to fill in a questionnaire related to how much and what type of dairy they consumed.
According to the researchers, those reported to eat the highest fat dairy products had an 8 percent smaller chance of becoming overweight or obese. Even though this might seem counter-intuitive, there are several theories for why both studies reported the conclusions they reported.
For the first one, the idea was that higher fat in the dairy helped with processing insulin better, as dairy fats can improve the body’s sensitivity to insulin. As for the second study, there are two explanations – eating high-fat dairy products is more satisfying, limiting the consumption of other products and more calories, and some low-fat products are in fact loaded with sugar, ending up being more fattening than full-fat dairy.
As a conclusion, both studies wanted to say that if you’re not a dairy consumer you shouldn’t become one because of what you’ve read; but if you are, go ahead and eat whatever type of dairy you prefer – hopefully one as close to natural as possible, as long as you do it in moderation.
