September 15, 2024 — “Poor diet is the leading cause of mortality in the U.S. due to the direct relationship with diet-related chronic diseases.” Emily Matthews and Emma Kurnat-Thoma tell us this in a recent article for Frontiers in Public Health. Rationalizing this conclusion is easy enough. In Nutrients, Sareen Gropper defines diet-related disease to incorporate almost all of […]
August 28, 2024 — Type 2 diabetes prevalence is up and the Lancet Regional Health has a simple way to reduce it. Daniel Windred and colleagues write: “Advising people to turn off their lights at night, or use lights that reduce the circadian impact (dim and “warm” light), is a simple, cost-effective, and easily-implementable recommendation that may promote cardiometabolic […]
August 22, 2024 — From time to time, nutritional epidemiologists take themselves entirely too seriously. This week is one of those times. Health reporting is full of warnings that your lunch sandwich might give you type 2 diabetes. The senior author of the paper in Lancet Diabetes and Endocrinology causing this stir, Professor Nita Forouhi, expresses no caution about […]
July 30, 2024 — The soft drinks industry levy came into effect in the UK in early 2018. The first study to investigate the effect of this “sugar tax” on individual-level consumption has just been published in the Journal of Epidemiology and Community Health. The headline finding is that adults reduced their daily added sugar intake by about two […]
June 11, 2024 — Keeping up with virtues and vices in food just keeps getting harder. Planetary health is a virtue to pursue, but ultra-processed food is a vice, and plant-based foods are virtuous unless they are ultra-processed. Then perhaps they become virtuous vices. So confusing. A series of publications this week adds to the confusion. In the American […]
May 1, 2024 — If you pay attention to nutrition headlines in consumer media, avocados sound pretty amazing. “Eating more avocados could help women stave off type 2 diabetes,” says one report. “Avocado a day may keep diabetes at bay,” says another. The only problem is that neither of the studies that prompted those stories actually support the claims […]
March 26, 2024 — Eight states have moved to provide nutritious meals at school for free to all students. A few simple reasons make it clear enough that this is a good idea. It reduces the stigma attached to receiving free school meals while improving food security for children from low-income families. Furthermore, nutrition quality goes up for all […]
February 29, 2024 — What could explain the observation that self-reports of exercise predict less of a benefit for men than women? In the Journal of the American College of Cardiology researchers nimbly leap to a conclusion that women get greater gains in mortality risk reduction from “equivalent doses” of physical activity. But would men exaggerate their self-reports? When […]
February 10, 2024 — The setup has been great. Kimchi lands near the top of the list of “must-eat fermented foods for a healthy gut.” On top of that, nutrition gurus advise us “food is medicine” and a fermented food diet “increases microbiome diversity and decreases inflammatory proteins.” So we should be ready to believe when a study tells […]
January 20, 2024 — 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 […]
