Cultivated meat: Lab-grown meat without killing animals

For thousands of years, humans have slaughtered animals for meat.  But Dr. Uma Valeti dreamt of a different way: eating chicken without having to kill a chicken. He figured out how to "grow" meat directly from animal cells.

It's completely different from the meat alternatives Beyond Meat or Impossible, which are made from plant-based ingredients, including vegetable proteins. "This is real meat, no compromise, made in front of you," Valeti said.

His company, Upside Foods, just received clearance from the USDA to start selling their meat, made at a production center in Emeryville, California. Here, the chicken is grown in tanks. "We'll be able to produce 50,000 to 75,000 pounds of meat every year, right away," he said.
