The world needs a new diet

NEW YORK - A hamburger a week, but no more, is about as much red meat people should be eating to do what's best for their health and the planet, according to a report seeking to overhaul the world's diet.

Eggs should be limited to fewer than four a week, the report says. Dairy foods should be about a serving a day, or less.

The report from a panel of nutrition, agriculture and environmental experts recommends a plant-based diet, based on previously published studies that have linked red meat to increased risk of health problems. It also comes amid recent studies of how eating habits affect the environment. Producing red meat takes up land and feed to raise cattle, which also emit the greenhouse gas methane.
