Hello and welcome to The Food Chain from the BBC World Service with me, Ruth Alexander.
Videos like this make me want to punch myself in the face.
These are the same people that tell you personal trainers need to be asked.
That's Michael Ujoa, a fitness coach who's built a following debunking online misinformation,
which is what this episode is all about.
We're going to be examining some of social media's wildest wellness claims.
The food and drinks we're told to fear, and those we're told are near miraculous.
I did enjoy on your feed a video you were critiquing where a kind of just with your facial expressions where somebody was swirling water and saying you swirl water in the glass and you basically change its composition and it's good for you.
I know I always think I've got a better poker face than I do and I get messages telling me that my face gives everything away.
It does.
Yeah I just like to try and have a bit of a laugh try and lighten the load around nutrition.
We'll hear more from Michael later.
