For those unfamiliar with Walter Willett, he once told the Washington Post that:
Anyone who cares about their health or the health of their family would not consume these beverages. Parents who care about their children’s health should not keep them at home.
Willett was also the engineer behind the trans fat railroad — or why you can’t get a decent doughnut anymore.
Now Willet is trying to mix his food nanny-ism with “sustainability” (aka Agenda 21). From the Harvard Gazette:
With an eye toward human-induced climate change, Willett showed an analysis of the greenhouse gas production required to produce different foods. Beef and lamb were the highest, producing 10 times the greenhouse gases used by the lowest-producing foods, beans and nuts. When looking at protein sources, Willett said that greenhouse gas production per pound of protein is related to how long an animal lives before it is slaughtered. The difference between a cow, which lives two to four years, and a chicken, whose life span from egg to slaughter is just weeks, makes chicken, from a greenhouse gas standpoint, more like a nut than a cow.
The lesson, Willett said, is that in making menu choices, the healthy option and the environmentally sustainable one are often the same.
