That article didn't mention worms. Here is something MH posted about vegans:
"I hate to say this, but do you know who always had the most parasites? The vegans! I seen some long time vegans that I told my wife, "I think that person is mostly worms", it just seemed like there was not enough places for them to have lived in the poor skinny persons. (I am sure many are ready to bite my head off about now!)
It is not hard to believe that great fresh raw foods right out of the garden, have plenty of fresh worms and eggs of plenty, especially those that make the fatal mistake of putting animal waste products to enrich the soil, you know that chicken stuff and cow and horse and God forbid the hog farmers garden.
The vegan would have done well to take de-wormer, oregano oil, and olive leaf as part of a plan to stay wormfree and these things would not have happened. You see, that is why I have zero doubt that education is the only real cure needed, once health as humans is understood, we need zero supplements, zero drugs, experience vibrant lives, etc. You get the point."
MH recommends brewers yeast for B12, wonder what this guy would say about that.
