Writing that is totally irresponsible and betrays how little knowledge the creators have about general nutrition and allergen health. Nearly very single item in their product is a well-known allergen, which includes soy, oat, canoloa, chocolate, etc.
Well, they are ALL on the label. So if you have a known allergy not on the label I can see the viability of using soylent to have a ready food supply known to be safe.
