Oh macrobiotics is an older strict healthy diet plan. It's a lot of whole grains, vegetables, fruits, fermented foods. George Ohsawa was the modern founder but he drew from older ideas. It deals with yin and yang, and eating foods local to you (such as no citrus fruits, unless you live in an area where you grow citrus fruits.) I liked it a lot. I have to admit I do like a bit of egg or fish here and there but I really, really only do that a couple of times a year.
