May 29, 2023 — Expert opinion holds that ultra-processed food is not a good thing. So it’s quite natural to expect that helping people resist the convenience and taste of this ubiquitous type of food will help with dietary health outcomes. So natural that it’s quite easy to dismiss inconvenient, unexpected findings. A little ultra-processing of study results in […]
April 22, 2023 — An “impassioned polemic” is headed our way from British media doctor Chris van Tulleken and it aims to have us excise ultra-processed from our dietary habits. No doubt about it, ultra-processed food wins the prize for today’s best food boogeyman, but how wise is this bit of food fear based on correlation without a cause. […]
March 15, 2023 — One of the most disappointing responses to the new guideline for obesity care in children and adolescents came from the Academy of Eating Disorders. Shortly after AAP published its evidence-based guideline for obesity care, the Academy for Eating Disorders issued a press release to criticize it. But their criticism used speculation rather than data to […]
March 4, 2023 — Today – World Obesity Day – is all about changing perspectives. The World Obesity Federation deserves credit for a well-chosen theme, because in the face of much new evidence about obesity, old perspectives are crashing into newer ones driven by evidence and science. Research has brought us new options for treating obesity more safely and […]
February 22, 2023 — Has the FDA bitten off more than it can chew? Two presidents ago, back in 2016, the FDA told us the agency had begun work to “redefine the term ‘healthy’” for food labels. Good luck with that is a fair summary of our reaction at the time. Seven years later, the quest to define objectively […]
September 12, 2022 — In popular culture right now, it seems that ultra-processed foods are the bad boys. “Ultra-processed foods linked to heart disease, cancer, and death, studies show,” says one recent headline. Scary stuff, eh? Targeting ultra-processed foods for scorn wins approving nods. But even if it supports a favored narrative, looking closely at research on ultra-processed foods […]
September 10, 2022 — Is it possible to have objective dialogue about red meat and health? Is it easy to find? The simple answer is yes and no. In Lancet this year, a pair of letters tell the story of why it’s so hard. These letters concern weaknesses in a massive analysis of the global burden of disease from 2020 […]
August 18, 2022 — The tension between science and policy at CDC is inevitable. But that tension has never been in plain view more than during the COVID-19 pandemic. And so, citing a “botched” response to the pandemic, CDC director Rochelle Walensky says that she will launch a sweeping reorganization of the agency. Her announcement was thin on specifics. […]
August 8, 2022 — 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 […]
August 6, 2022 — Can we find an intervention to reduce the prevalence of obesity across the population? Marion Nestle tells us one-size-fits-all obesity prevention doesn’t have much promise in her view: “My interpretation of the current status of obesity prevention research is that any single policy intervention is unlikely to show anything but small improvements.
