It's a great post and I like that you included the environmental aspect, which is very important. I am vegan myself, and I am confused as to why you say " I don’t recommend anyone to become a vegan because there are some negative aspects in this diet too". Really, there isn't. If you eat a varied diet, you can get all vitamisn you need and all the nutrients etc. I know plenty of vegans, and after years, our blood tests show optimal health. It might be different depending on where you live and the amount of products available.
As for the cheese with wine; I know that there are a lot of substitute cheeses that taste incredible (I love sheese). However, it is important to point out that most wine is not vegan, as fish guts, casein or other animal products may be used to filter the wine. That's a fun fact that most of you probably did not know. I'm not telling you to not drink wine (there are vegan wines too), but, it's valuable information to know ;)
well, vegan diet is not very balanced. Some vitamins, iron and calcium is hard to get from vegetables. Of course everything is possible, but it is a very strict diet and not everyone can follow it. Many vegans eat pastas, potatoes, and bread - and they have vitamin deficiency that leads to some health issues. Vegans should always check their blood levels. So, I can't recommend something like that - I can't be responsible in case someone gets very motivated by the post and decides to eat only vegetables and doesn't do enough research about vegan diet :)
Yeah, you need a lot of research and information to do it well. It's quite easy, there are many vegetables that give calcium for instance. My calcium was high, and as any other diet, blood tests are important. Example supplements are easy to get (at least where I live). None of the vegans I know have a vitamin deficiency and they all get their blood checked regularly, but they eat more than just pastas and potatoes :p
Supplements don't always work . Fresh veggies are always better, but not everyone can eat a lot of them to get good amount of vitamins. It is great that you and your friends have no vitamin deficiency, but not everyone is the same :)
There is also another issue that many vegans or vegetarians have - higher blood sugar level.
and as I said, I do think that being vegan is better than meat eater , but I just can't take this responsibility - to actually recommend it. Everyone should choose what they think is the best. I only want to create awareness about the benefits of being vegetarian.
and thanks about that info about wine, never heard of it . cool fact :)
