I've read several books about macrobiotics now and generally understand the balance of yin and yang principles, and avoiding certain foods is obvious. What I don't understand are avoiding some foods that would seem healthy to most other health ideas in the world.

The foods I'm talking about are:

Asparagus
Spinach
All nightshade family plants (Tomato, tomatillo, potato).

I understand that tomato and tomatillo are relatively new to European-descened bellies and that a potato is a quick response carb, but I am baffled by spinach and asparagus.

Any wisdom?
