Wow, another great educating post. I've been battling Lambs Quarters as weed for so long. But I hadn't clue that they are healthy. Book I bought abut healthy plants doesn't even cover it.
Just yesterday I told my wife a theory I came up with. And that theory says that those weeds that are all over the place are in fact nature's way to tell us what is healthy and a way to bring nature to balance. Furthermore, I guess that most of the allergies these days can be cured by using weeds in food. Considering that theory use of herbicides is one of the worst things that humans do to the environment and themselves.​
