Diet Soda: Beating a Correlation to Death

February 18, 2019 — How many times have we documented a correlation between diet sodas and cardiovascular disease? Who cares, say the editors of Stroke. Apparently, the click bait is irresistable. Thus, we have the upteenth correlation study, unsupported suggestions of causality, and a tidal wave of sensational headlines about diet soda, strokes, heart attacks, and death. We have […]

PREDIMED and the “Corpse” of Nutrition Science

February 14, 2019 — Last year, the New England Journal of Medicine retracted and then published a revised analysis of the landmark PREDIMED study. With that action, it shook the world of nutrition science. Even now, there’s still a whole lot of shakin going on. What About 267 Secondary Publications? Just last week in the BMJ, Arnav Agarwal and John […]

Real Evidence for Caution About Ultra-Processed Food

February 12, 2019 — Will ultra-processed food kill you? Probably not, but two new studies provide some real evidence for caution about this dietary boogeyman. First, a large observational study in France finds a 14 percent higher risk of death in a people who eat more of the stuff. And then, an RCT from NIH shows that ultra-processed foods […]

Obesity and the Food Supply: Assumptions vs Facts

February 11, 2019 — If there’s one assumption about what’s causing the global pandemic of obesity that is nearly universal, it’s the food supply. Some people describe it cautiously. Others not so much. For instance, the recent Lancet Commission report was pretty blunt. “Ultra-processed foods are a key driving force in the global obesity pandemic,” says the Commission. A Simple […]

What’s the Relationship Between Climate and Obesity?

February 6, 2019 — Last week, the Lancet Commission on obesity offered us a pretty bleak view of the future. The current approach to obesity prevention is failing. Food and fuel industries are dooming us to a future that is overweight, underwater, and malnourished. But what do the data say? Ruopeng An and Shen Zhang provide a systematic review […]

Obesity-Related Cancer Rising in Millennials

February 5, 2019 — Most often, when public health reports discuss the impact of rising obesity, the focus is on diabetes and its complications. Cancer does not spring to mind. But a new report in Lancet Public Health provides a disturbing jolt. Six obesity related cancers are rising, especially in the millennial generation. These are cancers that have always […]

The Cluster Fuss Continues with Two New Studies

February 1, 2019 — We keep hoping that editors and reviewers of obesity, nutrition, and physical activity studies will use a sharper eye when a cluster randomized trial comes to them. But two new publications tell us we can’t count on it yet. In both papers, the researchers claim to have proven the effectiveness of their programs. Yet neither […]

Canada offers us a new snapshot that tells us how it’s going there. If you believe the self reports, sugar in Canada is down. But the picture is […]

A Huge, Impossible Problem with Enemies All Around

January 28, 2019 — Bummer. The Lancet Obesity Commission report is out today and if you thought that obesity might be a tough problem to solve, you really have no clue. It’s bigger than you ever thought. It’s not just an epidemic. Not even calling it a pandemic is big enough. It’s a syndemic. A huge, impossible problem. It’s […]

When an Impact Does Not Cause an Effect

January 26, 2019 — The language of cause cause and effect is slippery. That’s what we’ve learned this week from the American Journal of Preventive Medicine. “The Impact of U.S. Free Trade Agreements on Calorie Availability and Obesity: A Natural Experiment in Canada” appeared last May in that journal. This week, the authors of that article explained that “impact” is […]
