What we eat – and how our food is produced – is becoming increasingly politicized. Why? More people are connecting the dots between diet and health – not just personal health, but also the health of the planet. And the central thesis that has emerged is this: If we eat less meat, it’s better for both.
So, how much less? A new, headline-grabbing report — compiled by some of the top names in nutrition science — has come up with a recommended target: Eat less than half an ounce of red meat per day. That works out to about 3.5 ounces — or a single serving of red meat — per week. And it’s far less red meat than Americans currently consume on average: between an estimated 2 and 3 ounces per day.
Here’s the environmental argument: Agriculture is responsible for up to 30 percent of greenhouse gas emissions globally, and much of the emissions come from red meat production. A lot of land and water are needed to grow the grains to feed the livestock. (About one-third of all the grain produced globally is used as animal feed.)
