Greg Foot is back to investigate more ad-hyped products and trending fads promising to make us healthier, happier and greener.

From personalised vitamin plans to NFTs, mindfulness apps to ‘sustainable’ jeans, Greg will find out if the latest wonder-products really are 'the best thing since sliced bread’.

And he wants YOUR suggestions for what to investigate! Is there something you keep seeing on TV or hearing about on a podcast? Have you spotted something trending on Instagram or TikTok and want to know if it delivers? Send us your suggestions to sliced.bread@bbc.co.uk or send them to Greg direct on Twitter or Instagram where he’s @gregfoot.
