The perils of ultra-processed foods received widespread coverage in recent months – thanks in no small part to the publication and promotion of TV presenter and doctor of virology Chris Van Tulleken’s book Ultra-Processed People. Ultra-processed foods, in short, are commercially manufactured food products that include ingredients you wouldn’t cook with at home. Some of this […]

Breastfeeding is such a good idea. But unfortunately, it doesn’t do much to prevent obesity. No matter. On the subject of breastfeeding and preventing obesity in children, we have policy-based evidence – the answer is preset. A new paper in Pediatrics lines up with this. Based on yet another finding of an association between breastfeeding […]

We do admire the tenacity of folks who promote the virtues of a plant-based diet. But that admiration stops when we move on to the dimension of scientific rigor and objectivity. In BMJ Nutrition, Prevention, and Health, a group of researchers are claiming that plant-based diets “may be considered protective against COVID-19 infection.” The only […]

Food as medicine programs can yield a fantastic medical benefit, say the promoters of this currently trendy concept in nutrition policy. If implemented broadly, they “would save lives and billions of dollars.” That’s the word from Tufts, where Dariush Mozaffarian is selling this concept with great enthusiasm. The whole idea behind these claims is that […]

An amicable discussion about evidence for the effectiveness of soft drink taxes can be, well, somewhat taxing. Scientists with genuine curiosity about this subject often seem harder to find than true believers. But disappointment has come for those true believers. Because some of the evidence to back their firm beliefs in soft drink taxes recently […]

Enthusiastic promoters of vegan diets are quite happy with headlines coming out of Stanford today.

They merely said “a vegan diet improves […]

As an article of faith, we like to believe that healthy habits will lead us to a longer life. So of course, it makes sense to develop healthy habits for eating, enjoy an active life, and get enough good sleep every night. But putting a number on the benefit of those habits is not so […]

Over the past 20 years or so, there has been growing concern that many research results published in scientific journals can’t be reproduced. Depending on the field of research, studies have found efforts to redo published studies lead to different results in between 23% and 89% of cases. To understand how different researchers might arrive […]

It’s a popular cause. Red meat production is a problem for the climate. Add that to ethical concerns some people have about consuming meat, and the push to reduce red meat consumption makes total sense. But when people start spinning misleading narratives about observational research and using them to promote this otherwise worthy idea, they’re […]

“Why do you see the speck in your neighbor’s eye, but do not notice the log in your own eye?” It is an ancient but fair question.
