Waheguru ji ka Khalsa, Waheguru ji ki Fateh,
As my sons have decided to go vegan , I was perusing some vegan sites and came across a pretty disgusting story ...the more I know the more Guru ji's bibek makes sense

I would read the whole thing including the comments section as many individuals have put in the legwork to find out just what is in the juices/smoothies and sodas.
BTW I don't drink or keep this stuff in the house but occasionally will buy ...so it is good to see how one cannot trust labelling alone.
