Are humans omnivores?
I'm curious to know if there is other masterminds out there.
Answer the question without regurgitating nonsense and bias.

Re: Are humans omnivores?
Well, there's a question to get your teeth into.
Re: Are humans omnivores?
Quoted from an editorial by William Clifford Roberts, M.d., Editor-in-Chief of the American Journal of Cardiology:
"When we kill animals to eat them, they end up killing us because their flesh, which contains cholesterol and saturated fat, was never intended for human beings, who are natural herbivores."
•Intestinal tract length. Carnivorous animals have intestinal tracts that are 3-6x their body length, while herbivores have intestinal tracts 10-12x their body length. Human beings have the same intestinal tract ratio as herbivores.
•Stomach acidity. Carnivores’ stomachs are 20x more acidic than the stomachs of herbivores. Human stomach acidity matches that of herbivores.
•Saliva. The saliva of carnivores is acidic. The saliva of herbivores is alkaline, which helps pre-digest plant foods. Human saliva is alkaline.
•Shape of intestines. Carnivore bowels are smooth, shaped like a pipe, so meat passes through quickly — they don’t have bumps or pockets. Herbivore bowels are bumpy and pouch-like with lots of pockets, like a windy mountain road, so plant foods pass through slowly for optimal nutrient absorption. Human bowels have the same characteristics as those of herbivores.
•Fiber. Carnivores don’t require fiber to help move food through their short and smooth digestive tracts. Herbivores require dietary fiber to move food through their long and bumpy digestive tracts, to prevent the bowels from becoming clogged with rotting food. Humans have the same requirement as herbivores.
•Cholesterol. Cholesterol is not a problem for a carnivore’s digestive system. A carnivore such as a cat can handle a high-cholesterol diet without negative health consequences. A human cannot. Humans have zero dietary need for cholesterol because our bodies manufacture all we need. Cholesterol is only found in animal foods, never in plant foods. A plant-based diet is by definition cholesterol-free.
•Claws and teeth. Carnivores have claws, sharp front teeth capable of subduing prey, and no flat molars for chewing. Herbivores have no claws or sharp front teeth capable of subduing prey, but they have flat molars for chewing. Humans have the same characteristics as herbivores.
But aren’t humans anatomically suited to be omnivores?
Nope. We don’t anatomically match up with omnivorous animals anymore than we do with carnivorous ones. Omnivores are more similar to carnivores than they are to herbivores. For a more detailed summary table that compares the properties of carnivores, herbivores, and omnivores side by side, see this page:
Comparative Anatomy & Taxonomy
The link above also debunks the opportunistic feeder theory, which states that because humans can eat like omnivores, that we must therefore be omnivores. And this is of course false because mere behavior doesn’t indicate suitability. There are plenty of things we can do as a species that would threaten our survival if we all considered them suitable default behavior, such as shooting each other, lobbing hand grenades, or sending spam.

Re: Are humans omnivores?
Yes humans are omnivores. Like animal we also eat flesh and vegetables.we can also say that we are omnivores. There is no wrong in this.First of all we must known the definition of omnivores after that this Question is answered.

Humans don't have the instincts to kill.

Re: Are humans omnivores?
Yes, but based in my own experience, I think the best option is to be vegetarian.

Technology is a tool which doesn't seem to contradict with our biochemistry unlike eating large quantities of meat.brad walker wrote:Humans don't have the instincts to pound their digits on magical omniconnective conglomerations of plastic, metal and silicon.
No doubt about it. For survival purposes. All animals have the protease enzymes to digest animal flesh for survival purposes. Cow eats chickens for survival. http://www.news.com.au/weird-true-freak ... 1113118642Synthesis proposal: Omnivorous humans were once scavengers.
Should we call all animals omnivores?
Since we have bacteria in our colon which can hydrolyze cellulose, not whole vegetation; the likely hood we are omnivores is zero unless you can point out an advantage of eating meat or fish as a brain evolutionary factor.
vegetarian means eating dairy products if you didn't know.Tensai wrote:Yes, but based in my own experience, I think the best option is to be vegetarian.
The question is whether humans are omnivores. Not what you think is the best option.

Actually, I don't even eat dairy products or eggs.vegetarian means eating dairy products if you didn't know.

The word vegetarian has been hijacked by the milk drinkers for some time now. Vegan is the new word if you didn't know.
You didn't understand.. should we call all animals omnivores because they can digest meat in survival situations?brad walker wrote:Why should we, two strangers on the Internet, care what each other calls anything? I hope to enjoy your response later tonight after a delicious dinner of Pizza Hut Super Supreme Stuffed Crust pizza with bacon substituting those awful green peppers. If it takes longer that's fine, too.Consistency wrote:Should we call all animals omnivores?
Its your funeral and don't make assumptions, I don't care about animals. Life and death are part of the universe.
Green peppers are awful. Its about following your instincts... sugar(ripe fruit and non-bitter leafy greens) and fat(nuts).
Why don't you just eat the bacon raw?
