Red Meat May Be Harmful

Red meat correlates with death.

The researchers carefully controlled for intakes of total energy, whole grains, fruits, and vegetables; age; body mass index; race (white or nonwhite); smoking status; alcohol intake; physical activity level; multivitamin use; aspirin use; family history of diabetes mellitus, myocardial infarction, or cancer; and baseline history of diabetes mellitus, hypertension, or hypercholesterolemia. In women, they also adjusted the data for postmenopausal status and menopausal hormone use.

Seems reasonably solid.

There are plenty of possible causal mechanisms, detailed here. Still no proof of overall causality, but it’s enough evidence to encourage moderation.

Things cooked at high heat (fried, well done, BBQed) are probably additionally unhealthy.
