The profile of vegetarians is as follows:

Vegetarians are generally defined as people who don't eat meat, fish, poultry and their by-products. Vegetarians can be divided into several types according to their aversion to animal products.

Vegetarian: Do not eat animal meat, including meat, poultry, fish (or seafood), and do not eat things from animal bodies, such as eggs and milk. Generally speaking, strict vegetarians do not eat honey and refuse to use any animal products, such as leather, silk, down, bone glue and so on.

Egg-milk vegetarian: Do not eat animal meat, including meat, poultry, fish (or seafood), but eat eggs and dairy products. Dairy vegetarian: Similar to an egg-milk vegetarian, but refuses to eat eggs. Oval vegetarian: Similar to egg-milk vegetarian, but refuses to eat milk.

There are other types of vegetarians, such as "fruitarian" (eating only fruits that fall naturally from fruit trees to avoid killing the plants themselves) and "Pescetarian" (eating fish instead of meat and poultry). Scientific vegetarian diet makes people healthier and live longer.
