Macrobiotic eating does not mean adhering to one unchanging "diet." It may mean eating in a more regulated, simple way, or in a more broadly varied way, depending on your needs, preferences, and circumstances - all of which change over time.
Macrobiotic eating means gaining your own understanding of how different foods affect you, and it means choosing, preparing, and consuming your food and drink with an active sense of reverence for life.
The macrobiotic theory places special emphasis on conscious diet, because regulating your daily eating and drinking is the most basic, practical way to change your life. The food you eat becomes your blood, affecting the quality of your cells, tissues, organs, and your mind.
