And I hate the most is the pseudo-scientific propaganda, related to veganism or some meato-phobia. People are eating meat for dozens of thousands of years, evolution made us everything-eaters and everyone who is healthy should eat everything. I can understand a person who eats gluten-free products due to the healthy reasons, or who doesn't drink milk, due to intollerance to lactose (like my grand-mother). But a healthy person should eat in normal, balanced way. People eat too much meat, too less vegatables, especially in countries like USA or Western Europe. Here in Poland we have pretty rich in everything diet, dishes are varied, a vegan would have no problem to create a good diet. But for me, as a foodie, interested in regional and traditionally-made foodstuffs it is a madness, not to eat a good Polish sausage or good ammount of traditionally roasted meat. But as I said, I do not like to eat too much meat, I like milk-based products, as a good alternative.

@Angela - Don't you think that list of yours is outdated? What legitimate nutritionist tells adult humans to consume milk these days? 6-7 servings of grains? Can you say "moo"? Might as well add toxic waste to your list. 

@Özgür zuury - we are omnivores. Accept that fact, and drop all the ridiculous comparisons. We can't digest grass, so we eat the cow instead. Get it?

Gerald's question was perfectly valid, but nobody answered it. Vegans have to eat much more in weight and volume than normal healthy omnivores to acheive proper nutrition. The smartest of the vegans supplement like royal shiny, but it's still a bad choice. 

I am not vegan nor vegetarian but I do not like to eat to much meat. I prefer to eat smaller ammounts of meat, for example 2-3 meat-based meals, a week. I do not critisize people who are vegan or even vegetarian, but I do not understand them. I'm a interested in food and nourishement in general for many years and I would say, it is not a problem to find a good alternative to meat. Especially in rich country with vast variety of food. But this "vegan" style is typical for rich countries, definitely not for poorer ones. I find it irrational, not to eat meat, when people are starving somewhere else and for me this is typical "Western" stupidity, people who have nothing more to do, are creating some idiotic styles. People say about "ethic", but is more important - massive starvation of people in poor countries, like India or Africa or some "style and living" idiocy, like veganism or vegetarianism. For me personally, veganism is an insult to the people who are begging for food, especially for the meat.

@kostya neither we are not in wild world nor we dont have to fight for survive. We are humans, and we save world for a long life together with whole life forms.

@Özgür let me respectfully ask you something, because that's a part of the vegan speech that always confused me. You said: "What you may not know is that you don't need to eat meat or cheese to get enough protein. For example green peas, quinoa, nuts and nut butter,beans, chickpeas,tempeh and tofu,edamame, and so on."

But when we check the nutrition information of high protein foods, it's hard to argue that it's almost impossible to get the same amount of protein one would get eating meat. For example:

100g of a lean cut of some kind of fatty fish (tuna, salmon) = 26g of protein. For the sake of measures, let's say 100g of fish is a regular piece of salmon.

100g of tofu = 7g of protein. 

That means that one should eat almost 500g of tofu (that's a lot of tofu) to get the same protein found on the fish.

So, all this mathematics to ask you: being a vegan, do you actually accept the fact that you will get less protein that someone that regularly eats meat? Or do you overeat some ingredients to reach to fulfill your protein needs?

Sorry for the long text :D
