Maybe of interest, from the BBC World Service ‘The Food Chain - Should You Drink Your Food?’
I haven’t listened to it myself yet, but based on the clips (below) it could be a bumpy ride, there’s even a guy moaning about becoming more productive.
It doesn’t actually mention Huel! It’s mostly about the trend to juice bars and juice “cleansing”. They do have an old audio clip of Rob Rinehart on the goals of Soylent. They speak briefly to the CEO of Bertrand. They talk to two different rather silly American professors of food science. One thinks if you don’t chew your food your teeth will fall out. The other thinks Soylent is no different from SlimFast or Ensure except for its “masculine, silicon valley persona”.
