Science Advisory: Children Should Keep Running with Scissors! (Except, of Course, not Really)

New Guidelines: No Need for Kids to Cut Back on Running with Scissors for Their Good Health. (Except, again…not really.)


Meat Eating and Your Health: Is There, Really, News?

The Annals of Internal Medicine has just published a cluster of systematic reviews and meta-analyses, all in the same issue, on the topic of eating meat and processed meat. All of these research papers show, consistently and with statistical significance, harms of eating more rather than less meat and processed meat. The specific harms these papers tabulate (see Table 1) include all-cause mortality, cardiovascular disease, cancer, and diabetes. Eating more meat and processed meat contribute to all of these- so say these research papers just out in the Annals, and sure to dominate the health news for some time (and likely doing so already).


The Emperor’s Healthy Climate

As I write this, children around the world- by the millions- are poised to skip school to protest our avarice, delusion, myopia, and irresponsibility, and demand action on climate change. As children speak their truth to the colossal failures of our power, we might all constructively recall that we were children once.


Diet for Human Performance: Does This Change the Game?

I am in the movie, The Game Changers, debuting at a thousand theaters throughout the U.S. on September 16. In all fairness, my role is rather closer to Mike Wazowski on TV than leading role- but still- I am in it. More on that later.


What is True? The Evidence Base for Evidence Based

To know that something is true - not to have faith in it, wish for it, hope, or believe it to be true, but to know - perhaps we can agree that you need some kind of evidence. To know something is true with a very high level of confidence, perhaps we can agree further that you need high-caliber, genuinely convincing evidence. Hold that thought while we toss an apple.
