September 13, 2020 — In nutrition, we encounter a fair amount of dietary dogma. But dogma is not confined to nutrition.

However, if the goal is better health, it’s essential. Both public and individual health […]
August 18, 2020 — For the Dietary Guidelines Advisory Committee, this was a relatively easy question. Americans typically consume too much added sugar. So the committee recommends a lower limit.

Through a project called FooDB, scientists have cataloged more than 70,000 biologically active chemicals that may be present in our […]

June 23, 2020 — Tamar Haspel tells a positively appealing story in the Washington Post this week. We don’t have a problem with obesity because of carbs, she writes. Nor fats, nor processed foods. The problem is the food environment. Cheap, convenient food surrounds us, with endless prompts to eat it. All these food cues, coaxing us to eat […]
June 18, 2020 — In ordinary times, yesterday’s meeting of the 2020 Dietary Guidelines Advisory Committee would have been big news. They were supposed to unveil their draft report.
