If Soylent actually were people, it would probably be easier on the digestion

Both in blogging and conversation, I can't think of a topic with which I've managed to offend more people than Soylent. I can't help but wonder if some of the fans who sprang to the product's defense later regretted their purchase. 

Eve Peyser writing for Gizmodo:

As you may recall, Soylent ended up recalling its Food Bar a month after releasing it when Gizmodo reported that it was causing customers to have “uncontrollable diarrhea” and vomiting, sending some to the emergency room. Soon after, Soylent halted sales of the 1.6 version of its powdered formula after people reported similar symptoms. The company eventually concluded it was the high-tech algal flour in the bars and powder that caused the illness, and vowed to remove it from future products.
