Healthy Whole Grains, Unhealthy Labels

August 12, 2020 — Who wants to eat healthy? Roughly nine out of ten of American adults. And at the top of their list for what’s healthy is fiber and whole grains.

Obesity Growing with Food Insecurity

August 11, 2020 — Food insecurity may well be the next pandemic that results from COVID-19. But new research in JAMA Network Open tells us that the problem is already here.

True, False, and Shades of Gray

August 6, 2020 — How are we doing these days on quizzes of true and false? In public affairs, it’s become quite a challenge. In nutrition and obesity science, the challenge is nothing new.

Cabbage Crowned, Lettuce Loses in Nutrition Correlation

July 25, 2020 — Is nutritional epidemiology suffering from overexposure? A study of veggies and COVID-19 mortality prompts this question. This exercise in nutrition correlation comes from a pre-print. So we can’t blame lax peer reviewers for this one. But the manuscript does make some remarkable claims: For each g/day increase in the average national consumption of some of […]

Dietary Dark Matter: What Are We Eating?

July 23, 2020 — Do you know what you’re having for lunch? You might think so. But in fact, the food that we are consuming is so complex, that we only have a vague idea of what’s in it. Through a project called FooDB, scientists have cataloged more than 70,000 biologically active chemicals that may be present in our […]

Social determinants of health . . . a healthy diet . . . food deserts . . . minority groups face hurdles. The authors piled on familiar phrases. In sum, […]

Policy-Based Evidence for School Nutrition

July 8, 2020 — If you work with the numbers long enough, you can get the answer you want. In Health Affairs, researchers claim to have found “a 47 percent reduction in obesity prevalence” due to the Healthy Hunger-Free Kids Act. Now that’s impressive evidence for the value of school nutrition! Reducing childhood obesity prevalence is indeed an impressive […]

Calories, Carbs, Quality, and Obesity

July 6, 2020 — For decades now, we’ve been debating the role of macronutrients in weight gain. But that fierce debate has yielded precious little consensus. Low-fat dietary guidance ruled the land for decades. Right now, low-carb diets seem to have the upper hand. However, in a new webinar, Kevin Hall suggests that neither calories, carbs, nor fat tell […]
