Healthy or Hoax is a new podcast series from RNZ that looks at the new-fangled fads and tempting new trends and asks if they're really up to much. In short: Do. They. Work? Presented by Carol Hirschfeld, with help from food writer Niki Bezzant and a host of experts, the series will report on the latest things in food, fitness and leisure and ask if they're all hype or if they're actually good for you. And because we're all busy, she'll do it in under 20 minutes. It's out soon. Here's a taste.
