I’ve realised that I’ve only mentioned being a vegetarian once in eleven years of blogging. Don’t go saying we drill about it all the time. Anyway, vegeterianism is a very wide concept and the TERMCAT (centre for terminology of Catalonia) have just created an infographic to make things clear.

As reducing meat and fish consumption becomes more popular, the spectrum of vegetarianism includes diets consisting of different foodstuffs. The TERMCAT has documented the names of these diets and the people who follow them. You can check their interactive infographic, but I’m also offering some descriptions from the most to the least restrictive diets.


I’ll only write the name of the diet, not the name of the people. To know what to call a person, you just need to remove the eding –ism. For example, if vegetarianism is your diet, you are a vegetarian. Some cases where the person has different names are marked with an asterisk and those names are at the end of the list.

1. Fruitarism: Fruits and seeds.
2. Veganism: Food of vegetal origin.
3. Api-vegetarianism*: Veganism + bee products (mostly honey).
4. Lacto-vegetarianism: Api-vegetarianism + dairy products.
4. Ovo-vegetarianism: Api-vegetarianism + eggs.
5. Ovo-lacto vegetarianism: Api-vegetarianism + dairy products + eggs.

*Api-vegetarianism: api-vegetarian, beegan or honeytarian.

As you can see, the addition of a new element is marked with a higher number. Number 4 is repeated because both cases add an element to level 3, while livel 5 includes both additions.

Notice that there are two levels of veganism. While some people only follow a vegan diet, others follow a vegan lifestyle. A vegan lifestyle goes beyond a diet; a vegan lifestyle avoids any product obtained through animal exploitation, that is fabric of animal origin, cosmetics tested on animals or shows involving animals.

But wait! The spectrum doesn’t end here. Flexitarianism or reducetarianism includes occasional consumption of meat or fish. People in this group are flexitarians or lessetarians. There are three more diets in this group.

6. Pollotarianisme*: Ovo-lacteo vegetarianism + occasional consumption of poultry.
6. Pescatarianism or pescetarianism*: Ovo-lacteo vegetarianism + occasional consumption of fish.
7. Pollo-pescetarianism: Ovo-lacteo vegetarianism + occasional consumption of poultry and fish.

*Pollotarianism: pollo-vegetarian or pollotarian.
*Pescetarianism: pescetarian, pesce-vegetarian or pesco vegetarian.

While the TERMCAT included the denomination pollo-pescetarian, they didn’t offer the English version pollo-pescetarianism. This word is an addition of this blog supported by their denomination of the person and a search that proves its use.

Finally, if your consumption of poultry or fish is not occasional or you eat meat of mammals, there is no flexing that includes you. Let’s call a spade a spade. And what am I? I’m a translator and a chemist, in case the name of this blog wasn’t clear enough…
