Spotted this on reddit. The whole video is well worth a watch, interesting subject with great delivery.
Penn gets asked about Soylent at 31:44. Summarised, he doesn’t really trust ‘lents because he doesn’t think science really knows enough about the nutrients that the human body needs.
It’s a fair comment. Just look at what we’re being told about fat, salt, sugar, cholesterol, and compare it to nutritional advice from just a couple years ago.
We each have to satisfy ourselves that what we consume is right for us, not just take everything at face value.
