I ran across some nutrition-advice videos of Dr Michael Greger six months ago and started following him at Twitter. It soon became clear he favors a vegan or vegetarian diet. Dr. Harriet Hall at Science-Based Medicine has Dr. Greger in her crosshairs, challenging many of his claims. Well worth a read. An excerpt:
Vegans tell us the Inuit, who lived almost exclusively on food of animal origin, had a short life span. That’s not true. Statistics on the Inuit between 1822 and 1836 showed that their average life expectancy was about the same as that of European peasants of the time who ate a diet overwhelmingly based on bread. 25% of Inuit lived past 60, and some lived into their 80s and 90s.
