How very interesting. The title made me laugh, especially as you'd started the medical MJ thread too. I'm thinking, good grief, he's calling MM's medicine I gotta see this.
It seems nature provides again - less sun and the fungi arrive.
I wonder what animals get vitamin D from when it snows?
I wonder what the vitamin D content of mycelium (mushroom root mat) is under the ground when mushrooms are fruiting and recieving sun. And if the mycorrhizal fungi in the root mat deliver excess vitamin D to plants when fungi fruit as well.
This may happen, keeping plants with adequate vitamin D until it gets too cold then the fungi rot and the nutrition taken into the soil by bacteria and other organisms for winters store of vitamin D... At a quantum stretch....
Natural is always better than synthetic. I'll be freezing field mushrooms this Autumn with this knowledge (knowledge being Michael's posts not my theorising...), thanks Michael.
Sun, then field mushrooms, then frozen, the diet plan.
I see you read Dr Mercola, he's very good.
