No, an egg is not considered a vegetable within the traditional definition of vegetarianism.
Vegetarianism, by definition, excludes the consumption of animal flesh. According to the provided reference, "vegetarianism is classified as excluding any form of animal flesh (the tissue, muscles or meat of an animal)." Eggs do not fall into this category and are therefore included in a vegetarian eating pattern for ovo-vegetarians but not for vegans.
Here's a breakdown:
- Traditional Vegetarianism: Typically excludes the consumption of any animal flesh, including meat, poultry, and fish.
- Eggs: Eggs are an animal product, but not animal flesh. They are produced by hens.
- Ovo-vegetarian: A type of vegetarianism that allows the consumption of eggs.
- Veganism: Excludes all animal products, including meat, dairy, eggs, and sometimes honey.
Therefore, while eggs are acceptable in some vegetarian diets, such as ovo-vegetarianism, they are not considered vegetables. The key distinction lies in whether the food source is derived from animal flesh. Because eggs are not animal flesh, they do not violate the core principle of vegetarianism.
