I won't eat them. They don't actually extract that one chemical from soy, they synthetically produce it - so it's Soylent green type shit. Granted I'm old so I can eat whatever and I'm not making anymore children on purpose, but I definitely would not let my child/grandchild eat impossible...
Always use your pet to test a water source if it comes down to it before yourself. Great for in cities where you use a filtered water machine. Use the first gallon on your pet before drinking it.
