Vegetarianism is a food system that excludes products of animal origin. But whether vegetarians eat fish - a controversial issue, the answer to which can be given only by knowing the individual reason for switching to vegetarianism of each individual person.
Vegetarian Vegetarian Dissension
There are vegetarians who prefer this style of food and life from ethical considerations. They do not eat animal products, because they do not want to harm the surrounding fauna by their existence.
Naturally, these vegetarians do not eat fish, because for them both the fish and the chicken are the meat obtained as a result of the tortures of the animals. There are other vegetarians. They gave up meat for health reasons. A well-known fact is that the fish contains more easily digestible protein and less fat, so it is really recommended to people aged and different diseases to switch to so-called "fish-eating".
It's also silly to ask whether fish can be eaten by vegetarians living in coastal areas. The Mediterranean diet itself presupposes the predominance of "seafood" in the human diet . Many people who live on the coast do not even think that they adhere to "soft" vegetarianism, because, without noticing, they can not eat meat for years.
It can not be said that "fish" vegetarianism is more or less useful than the classic rejection of all products of animal origin. For example, athletes need more red meat, older people - more fish, and if you talk about diseases - for some diseases the fish is welcome, and with others, you need exactly that meat.
Vegetarianism is even called a menu with a predominance of chicken meat. This contradicts ethical vegetarianism, as does the fish menu, but belongs to the category of vegetarianism by doctors and nutritionists.
