macrobiotic wha?

I was reading the Changing Seasons Macrobiotic Cookbook by Aveline Kushi and Wendy Esko (in amazon's LookInside! edition, whatever) and was jamming along, regional vegan diet, whole grains, miso soup with seaweed every day, I could do this, at least for a month as cleanse, and then i got to this:

Unless you live in a tropical climate, avoid the foods of tropical origin (listed in the last column) whenever possible, because they are difficult to balance in the body. ...

• asparagus
• avocado
• bamboo shoots
• beets
• eggplant
• ginseng
• green and red peppers
• Jerusalem artichokes
• okra
• potatoes
• spinach
• sweet potatoes
• Swiss chard
• taro (large ones)
• tomatoes
• yams
• zucchini

and my first reaction is basically, no can do.  What's recommended? Lots of squash and roots and all the tougher, more bitter greens.  They pad the list with "lotus root, fresh or dried; lotus seeds", and note that leeks, onions and scallions are all on the Regular Use list, though garlic isn't mentioned at all.
But then I looked more carefully at the Tropical list: it's all the nightshades, starchy/sugary tubers, and stuff that won't grow in this climate.  But, but, nightshades are so delicious, especially fresh in season like right now.  On Thursday let's compare the CSA haul to that list.  Maybe I'll even put the book in my shopping cart.
