However they do still ask lots of questions. My boyfriend (a pure bread Italian who loves his steak) and I have had many discussions, on the pros and cons of a plant-based diet. Co-workers, who I am still getting to know, are starting to comment on my lunch's. Again, most of them are open-minded but there are a few guys who just plain ignore the pure facts I put before them and move on to their next ignorant comment.
So to anyone reading this blog that is a newbie like my self to the plant-based diet, here is the arsenal I've discovered you will need to handle the uneducated.

The above is a table noting all the physical differences of Humans VS Omnivores VS Carnivores. For any passionate meat eater that has read this far I can hear you racking your brain for the best refute ever. Let me just say, that its ooookaaayyyy, calm down and take a few deep breaths. Right now you are going through a very natural process. When confronted by the realization that our current choices may not be the best choices, it can be unnerving. This leaves us with two options, 1) We admit that we are wrong, which for some people is very difficult to admit, or 2) We reaffirm our beliefs with any excuse that comes to mind until we are in a more comfortable position. So if you are currently finding yourself in such a position its OK, it has a name : Cognitive Dissonance
Now that we can all move on lets take a look at some common misconceptions...
"Humans were made to eat meat."
In some form, this is usually the first point made when discussing the plant-based diet. It covers so many topics that first I'm going to reference the table above. As it describes there is nothing about us that screams KILLER!!! I've heard humans being compared to Carnivores! I figured I wasn't talking to the sharpest tool in the shed. Just to clarify a carnivore is defined as a flesh eating animal. Now I've never seen another person start to salivate when they saw road kill or go running through a field to a grazing cow and start gnawing on it. If they did I don't think that person would be defined as Carnivore, but as a deranged lunatic!
"We have Hydrochloric Acid in our Stomachs"
Yes, HCL is an acid that is secreted by out stomachs to aid in the digestion of protein. This acid believes in equal digestion for everyone! Whether your an animal source of protein or a plant source of protein, it will not discriminate. How great is that?!
It's also important to note that your stomach secretes this substance in small amounts, such as the amounts in a plant based diet.... what a coincidence!
"I have canine teeth"
Those four teeth at the front corners of your mouth are canines in name only. The do not function in the same way as your pet cat's. If you so feel the need, give the mirror a nice big toothy grin :D nope, no razor sharp canines in there! As the table so well describes it, human canines are short and blunt.
While on the subject of teeth, its important to notice that the majority of human teeth are molars, the perfect shape for grinding down plant matter.
"Humans have always ate meat"
This comment was in reference to the cavemen days... personally I don't let cavemen influence my crucial life decisions! But the point was raised so I shall address it.
Our Furry Friends are born knowing what is and what is not food. Humans act through learned behavior or even guesswork, but rarely on instinct.So even if our ancestors did eat meat, it's no argument explaining that we should eat meat. Just because some people choose to eat McDonald's everyday doesn't mean they should.
"We've evolved since caveman days to eat meat"
No we haven't.
We've grown a liking for the taste of a "well prepared", cooked piece of animal protein. We have grown a liking for the taste for a lot of things that are unhealthy. Take cigarettes for example, 50 years ago doctors were testifying to their amazing health benefits!!!
We were brought up to believe that a healthy balanced diet included eating Furry Friends, chicken gametes, muscle fibers and drinking lots of newborn baby cow formula. Do I sound like a baby cow to you?!
~~~~~~~~
This is the majority of what I'm hearing. I'm positive there will be future funny ignorance's to come and I will be sure to update this page so you can be better prepared. As a nursing student I do have some education in Human anatomy and physiology. However if you need more proof it is all available and highly abundant for everyone to read. Just remember to look for credible sources and that anything I have to say is not to contradict your personal doctors advice.
