Humans: Should We Eat Plants or Meat

Carnivore

image17

Animal that has a diet primarily of meat. These animals usually have claws for attacking prey and their saliva is acidic. They also have a smooth and short intestinal tract about 3-6 times the length of their torso which allows for quick elimination and avoiding build up in the intestinal walls. (Ex. Lions, Spotted Hyena, Polar Bear, Tiger, Jaguar, etc)

Omnivore

image18

Animal that can consume a plant based diet but can also has claws and fangs to hunt prey and can consume meat and have acidic saliva. Their digestive system is similar to that of a carnivore, short and smooth to eliminate meat immediately after eating to avoid meat sticking to intestinal walls. (Ex. Brown Bear, Raccoon, Fox, Dog, Skunk, etc)

Herbivore

Animal that needs to consume a plant based diet for nutrients. Their saliva is alkaline and are some of the biggest animals on the planet. Their intestinal tract winds in different directions, has pockets and is about 10-12 times the length of their body. This helps to capitalize on absorption of plant nutrients. (Ex. Elephant, Deer, Cow, Hippo, Gorilla, etc)


Humans are most similar to herbivores. Although human society has adapted to an omnivorous culture, biologically, humans have a herbivore's digestive system. This is why humans on a plant based diet are less prone to health complications. 

Frugivore

A frugivore is a fruit eater. It can be any type of herbivore or omnivore where fruit is a preferred food type. Because approximately 20% of all mammalian herbivores also eat fruit, frugivory is common among mammals. (Ex. Chimpanzee, Orangutan, Fruit Bat, Maned Wolf, Flying Fox, etc)

Vegetarian

image21

A person who does not eat meat, and sometimes other animal products, especially for moral, religious, or health reasons. 


There are several types of vegetarians. 


Lacto-Vegetarian: Do not consume meat or eggs however might eat dairy.


Ovo-Vegetarian: Do not consume meat or dairy however might eat eggs


Lacto-Ovo Vegetarian: Do not consume meat however may eat dairy and eggs. 


Plant-Based: Someone who does not consume anything from an animal however, may still purchase animal by products for others and wear animal byproducts. Being on an plant based diet only for health reasons and not concerned much for the planet or the animals is being a vegetarian not a vegan. 

Vegan

A vegan is someone who does not use, buy or consume anything from an animal  or has animal by-products in the ingredients. Vegans also do not support organizations, events and/businesses that use animals for profit, entertainment and/or experimentation.


Being a vegan is a discipline in which thinking of others is very important, giving up on convenience is one of the first disciplines. 


Animal agriculture is the leading cause to global warming, animal extinction, animal cruelty, health issues, etc., so anyone who refrains from consuming animal byproducts is appreciated. 


However, if claiming to be vegan one must be disciplined and understand buying it for others, using animal byproducts and supporting events using animals when convenient is not practicing veganism, that is being a vegetarian.
