PBS News Weekend 
Season 2, Episode 4 of 4
On Sunday, NewsHour Weekend examines the Paleo Diet, which has gained popularity in recent years. Advocates of the diet promote eating foods they say are more in line with what our ancient ancestors ate, such as meat and vegetables rather than dairy and grains, which were introduced after the invention of agriculture. But the diet's modern version may not actually give an accurate picture of what our predecessors really ate. Science writer Ann Gibbons joins NewsHour Weekend's Hari Sreenivasan to discuss how to follow the real Paleo Diet. That, and the weekend's news, online and on-air.
