Ultra-processed food - things like biscuits and crisps - are making up more and more of our diets globally. In the US and the UK, ultra-processed food actually make up half the calories we eat. New research is calling for more action to reduce this intake because of its potential threat to our health. But what is ultra-processed food and how does it impact the body? We’re joined by the BBC health reporter Annabel Rackham and Priscila Machado, a nutritionist from Deakin’s Institute for Physical Activity and Nutrition in Australia, to talk through everything we need to know. We discuss what ultra-processed food is, what it contains, how to spot it, and if we need to worry about eating it.

American astronauts Neil Armstrong and Buzz Aldrin landed on the Moon in 1969. The landing was televised and watched by around 600 million people around the world. That and subsequent missions have brought back 382kg of moon rock. More than 400,000 people work on the American space programme to get people to the Moon; scientists, engineers, researchers and support staff along with the astronauts.But still, some people don’t believe the Moon landings actually happened and think the whole thing was staged or faked, possibly with the help of Hollywood. Among them are Kim Kardashian, Joe Rogan and YouTuber Shane Dawson. And they’re not alone. In some surveys, as many as 25% of those asked agreed with a statement that the Moon landings had all been a hoax. Results differ by age group, but some surveys have also found there’s even more doubt about the Moon landings in young people, compared to older age groups. In this episode, Nathalie Jimenez, our BBC reporter in New York and Jacqui Wakefield, a BBC global disinformation reporter debunk some of the conspiracy theories about the Moon landing and discuss why younger people are more likely to think it was staged.Audio of Moon landing used courtesy of British Pathé.
