Kimchi for the Win in Obesity? Not Really

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.

Loose Takes on a Study of Red Meat and Type 2 Diabetes

October 25, 2023 — It’s a popular cause. Red meat production is a problem for the climate.

Straining to Rationalize Vegan Cat Food

September 15, 2023 — By nature, cats are killers, not vegans. Veterinarians will tell you that they are obligate carnivores. Biologically, they require nutrients that come only from the flesh of other animals. But about 12% of pet owners are vegans or vegetarians.

The Washington Post this week published a prime example, telling readers: “The food industry says sugar substitutes help people manage their weight and reduce intake of added sugars. But studies suggest that fake sugars can also have unexpected effects on […]

February 24, 2023 — The headlines make us dizzy. “For a longer life, afternoon exercise may be best,” says the Washington Post. “Morning Workouts May Lower Your Risk of Heart Attack and Stroke,” according to Verywell Health. However, BBC offers yet another view with a headline saying, “Best exercise time may differ for men and women.” Despite the wild variations […]
