To start an impassioned discussion on nutrition is easy. Bring up non-nutritive sweeteners. Some people see them as a plague in the food supply. Others insist upon evidence to back up such dire claims and can see only fragments propping up presumptions about harms that are yet to be documented. But once again, a study […]

Fast food and junk food are slippery and pejorative terms that many people equate with a risk of obesity. Most people – even people who routinely consume it – presume that fast food is not good for health. With the release of Super Size Me in 2004, we seemed to hit a peak in the […]

A fascinating debate is unfolding in the Proceedings of the National Academy of Sciences (PNAS). It’s mostly about publication bias, but the bottom line question is not so esoteric. Can a nudge make meaningful behavior change happen in a wide variety of situations? Late last year, Stephanie Mertens and colleagues published a meta-analysis of nudging […]

It’s hard to argue with something dubbed “the sunshine vitamin” – more specifically, vitamin D. It’s been generating headlines and controversy for years now. The vitamin D fan club described it like a panacea, good for preventing bone fractures (of course), but also ills ranging from infections to diabetes and cancer. Because of its association […]

Institutions of public health are in a tough spot right now. COVID has so battered public trust in the CDC that it has put us into the figure-it-out-yourself phase of this pandemic. Likewise, the public health response to obesity has long been one of both moral panic and ineffective policy prescriptions. Decades of exhortations to […]

Every week from the Obesity and Energetics Offerings, we get sharp reminders. Headlines about nutrition and obesity science very often don’t stand up to a careful look at what the study behind the headlines actually found. This charade, though, has a serious downside. As two studies in the last week show, it perpetuates a fiction […]

Nonalcoholic steatohepatitis – NASH – has yet again handed drug researchers disappointing results, this time in a study of semaglutide. Researchers presented this phase 2 study at the International Liver Congress in London last weekend. The whole point of a phase 2 study is to see if a drug works for a specific purpose. On […]

The ASN Nutrition Live 2022 virtual meeting started with a feisty debate yesterday. The architect of the NOVA system for identifying ultra-processed foods – Carlos Monteiro – made the case for his magnum opus. Then, in this debate he faced off with nutrition professor Arne Astrup, who made the case that relying on the NOVA […]

Talk is cheap. But history tells us that cheap talk doesn’t solve wicked problems. That’s true whether the problem is the relentlessly rising health harms of obesity or the current hot topic – inflation. The notoriously hollow Whip Inflation Now campaign of Gerald Ford seems like a model for equally ineffective campaigns aspiring to overcome […]

It’s great sport or a great folly. Body mass index – BMI – is a simple measure and an easy target for so many people. It saves many people for many reasons from having to think about obesity. Clinicians who don’t want to think too hard about obesity might use BMI, mistakenly, all by itself, […]
