If you’ve longed for the day when scientists announce pizza is actually good for you, you *may* be in luck. It turns out there’s no such thing as a universally wholesome diet  - what’s healthy for one person might be harmful for the next.In the pod this week are New Scientist journalists Rowan Hooper, Valerie Jamieson and Graham Lawton.The team discusses the advent of a healthy eating revolution. “Precision nutrition” aims to measure the metabolic response of individuals to certain types of food, to figure out what foods are good and bad for people on a personal level.

The team hears about Vladimir Putin’s thoughts on the potential for gene editing in humans, discusses China’s recent launch of a reusable space plane, and checks in on the “Great Green Wall” project to plant a belt of trees across the whole width of Africa.To find out more, subscribe at newscientist.com/podcasts.
