"but this vegan thing" -spoken like a true novice; have you personally done a 30 days trial run? It's only 30 days of your entire lifetime. We are not "all different" either; we have species specific nutrition. A Shark, eats fish. A Squirrel eats nuts. Horses eat green grass/plants. The species-specific nutrition applies unquestionably to our fruigivores physiology; of all human beings. I am not on Steemit to debate with energy-draining-skeptics, I am here to serve the awakening and aware; "NEXT!!!"

I encourage you try 30 days, before you reply. How can we know anything for certain, without personal experience? Peace be with you. I love u.
