Many people think of vegetarians as one homogeneous group that just doesn’t eat meat. But nothing could be further from the truth. There are different categories of vegetarians as diverse as the reasons for going vegetarian in the first place.
A vegetarian is generally defined as someone who doesn’t eat meat. But someone who is vegetarian could conceivably eat dairy products such as milk, eggs, and cheese. A Lacto Ovo vegetarian doesn’t eat meat, fish or poultry, but does consume eggs, milk, or cheese. A Lacto vegetarian consumes milk and cheese products but doesn’t consume eggs.
A vegan is someone who doesn’t consume any animal product or by-product, including dairy food. They eat only vegetables, fruits, nuts, grains, and legumes. They also don’t use animal products, such as leather. Vegans also don’t use white sugar because it’s often processed with a substance derived from animal bones that whitens the sugar.
There are other categories within the vegetarian community. Fruitarians, for example, eat only fruit. Their rationale is that fruits, including fruits such as tomatoes, are self-perpetuating and don’t need to be planted to create the food source. They consider it a way of eating that’s most in balance and harmony with the earth, the most natural.
All of the above will eat cooked vegetables, fruits, and legumes. There is also a growing movement towards eating only raw or living foods. This based on the assumption that cooking food processes most of the nutrients out of it, and to get all the nutritional value, vitamins, and amino acids from food, its best consumed raw or juiced. If cooked at all, it should only be cooked to slightly over 100 degrees, so the nutrients are still retained.
The more restrictive you become with your diet, however, the more educated you need to become to be sure you’re getting all the necessary proteins and vitamins that you need to maintain good health, especially muscle and heart health.
