Other dietary practices commonly associated with vegetarianism

• Fruitarianism is a diet of only fruit, nuts, seeds, and other plant matter that can be gathered without harming the plant.
• Su vegetarianism originating in Hinduism, excludes all animal products as well as the fetid vegetables: onion, garlic, scallions, leeks, or shallots.
• Macrobiotic diet is a diet of mostly whole grains and beans. Not all macrobiotics are vegetarians as some consume fish.
• Natural hygiene, in its classic form, recommends a diet principally of raw vegan foods.
• Raw veganism is a diet of fresh and uncooked fruit, nuts, seeds, and vegetables.
• Dietary veganism: whereas vegans don't use animal products of any kind, dietary vegans restrict their veganism to their diet
• Freeganism argues that all commodities produced under capitalism, not only those from animal sources, contribute to exploitation and avoid buying anything, including food. While many freegans are vegans or vegetarians, others will eat animal products that would otherwise go to waste under the justification that doing this does not encourage further animal exploitation.

It should be noted that most vegetarians also are aware of avoiding products that may use animal ingredients not included in their labels or which use animal products in their manufacturing i.e. cheeses that use animal rennet, gelatin (from animal skin, bones, and connective tissue), some sugars that are whitened with bone char (e.g.can sugar, but not beet sugar) and alcohol clarified with gelatin or crushed shellfish and sturgeon.

Semi-vegetarian diets

Semi-vegetarian diets are diets that primarily consist of vegetarian foods, but make exceptions for some non-vegetarian foods. These diets may be followed by those who choose to reduce the amount of animal flesh consumed, or sometimes as a way of transitioning to a vegetarian diet. These terms are neologisms based on the word "vegetarian". They may be regarded with contention by strict vegetarians, as they conflate terms for vegetarian and non-vegetarian diets.

• Semi-vegetarianism — A diet in which the only animal flesh consumed is eafoodand/or poultry, in limited amounts.
  • Pescetarianism — A diet in which the only animals consumed are fish or other seafood.
  • Pollotarianism — A diet in which the only animals consumed are fowl and poultry.
• Flexitarianism — A diet that consists primarily of vegetarian food, but that allows occasional exceptions.
