Types of Vegetarians and Vegetarianism
Macrobiotic Vegetarians
A macrobiotic vegetarian diet excludes all meat, poultry, dairy produce and eggs, but at initial levels may include fish.
Macrobiotic Diet - 10 Levels
A macrobiotic vegetarian aims to maintain a balance between foods seen as ying (positive) or yang (negative). The macrobiotic diet progresses through ten levels, and becomes more and more restrictive. Not all levels are vegetarian, though each level gradually eliminates animal products. The highest levels eliminate fruit and vegetables, eventually reaching the level of a brown rice diet.
A macrobiotic vegetarian diet is not recommended from a nutritional viewpoint.
Pescetarian Vegetarians
A pescetarian diet excludes meat and fowl but includes fish, although factory-farmed fish are usually avoided. A pescetarian diet is perfectly healthy.
Fruitarian Vegetarians
A fruitarian diet is a type of vegan diet which includes a minimum of processed or cooked foods. It consists mainly of raw fruit (75 percent), fruit-like vegetables (e.g., tomatoes, cucumbers), grains and nuts. Fruitarians eat only plant foods that can be harvested without killing the plant.
Fruitarian diets are not recommended from a nutritional viewpoint.
Sproutarian Vegetarians
Sproutarians eat mostly sprouted seeds, grains, pulses and rice.
