The Macrobiotic Diet Vegetables: 20-30% - Recommended vegetables include green cabbage, kale, broccoli, cauliflower, collards, pumpkin, watercress, chinese cabbage, dandelion and mustard greens, scallions, onions, turnips, carrots and winter squash. Cucumbers, lettuce, celery, chives and dill are also permitted on occasion. Potatoes, tomatoes and eggplants are not permitted as they originated in tropical regions and the fact that they are eaten in temperate climates is believed to contribute to the loss of natural immunity. Other foods that are limited to occasional use are fish, fruit, nuts and seeds. Fruits grown locally and native to ones' area have to be consumed. Along with the recommended grains and vegetables, another 5-10% of the intake should come from soups made with those listed, as well as a final 5-10% of the intake is from cooked beans and sea vegetables, such as nori or wakame. Although these vegetables are not local for many people, they are recommended because of their high vitamin and mineral content.
