The podcast that investigates
bold claims
being made by promising products.
NEWS! 'The Best Thing Since Sliced Bread?' is now a BBC Radio 4 series!
Listen to the radio episodes here and the extended podcasts here!
YouTuber & TV Science Guy Greg Foot is on a mission to bust some marketing BS.   
At a time where science fad
seems to outsell science fact
we need more great stuff like this.
I can’t wait for the next installment.
Joined by experts, his mates, and people on the street, Greg goes in search of the  evidence to find out whether these wonder products really are the best thing since sliced bread?
Do the “billions of good bacteria” in ‘Probiotic’ drinks actually “make your tummy smile”?
Episode 2:
Can a ‘Wake-Up Light’ really “keep your sleep cycle on track and brighten your winter blues”?
Fun & enjoyable... weave[s] expert opinions and in-studio product test tomfoolery into a very enjoyable half hour (so enjoyable I thought it had only been 15!)
