I haven't eaten meat since '93 and have been vegan for 12 years. I am 6'2" 190lbs and don't think that most vegans are unhealthy.If you are an unhealthy vegan, its probably not your diet that you should be examining.
Eggs are an animal product and I don't consider them to be vegetarian at all. Lab grown meat is just plain weird. I wouldn't eat it but I am sure there are vegans that would consider trying it.
I have pretty much no cholesterol when I have blood work done and my blood pressure is 120/70. Most of my family are meat eaters and have cholesterol and blood pressure issues.
Not trying to stand on a soap box but if you think Veganism is unhealthy then you're definitely doing it wrong.
