So U think Vegan is healthy?

[Aractus]

So why are you so against it? You clearly are aware that it isn't actually unhealthy for most people. So some people need meat. Good for them. That has nothing to do with the people do don't need meat and/or don't want to eat meat.

Eating meat is not unhealthy for most people.

Vegetarians and vegans tend to live longer than people who eat meat.

That's a lie.

• There are an estimated 60,000 centenarians in the United States, 9,000 in the United Kingdom, and 3,000 here in Australia. Most are meat eaters and a few are vegetarian, but I’ve never heard of any who are vegan or fruitarian.
  In fact, in one of the world’s longest-running studies of authenticated centenarians ever undertaken, it was found that none of the participants were vegan, fruitarian or even vegetarian! The Okinawa Centenarian Study has been ongoing since 1976 and examined the lives of over 600 centenarians who were living their traditional lifestyle. Their diets included fish, pork, poultry, dairy products and eggs.

That's not because we don't eat meat, but because we're generally more conscious of what we're eating than meat eaters, and the result is often a healthier diet. Now, if not eating meat was actively unhealthy for humans we wouldn't see this difference in life span because the deadly effects of the meatlessness would knock a few years off of us.

You don't see an improvement in lifespan, you've (or rather, others have) cherry picked data to say it supports your claim. Many people get sick on a vegan diet even under advice from vegan doctors and have to return to eating meat.

If you're actually interested in how healthy different diets are, I suggest you go and do some more research into the paleo diet and other high-protein diets. Specifically, the dangers of said diets, which I personally have read are linked to increased risk of heart disease and various cancers. One article I read suggested these diets can be as dangerous as smoking. So that might be an interesting one to look into.

I think we both agree that extreme of any type of diet are bad - for instance raw vegan is very bad for anyone and recognized as such. Paleo is a label that is as broad as the vegan label, but at its cores it's less restrictive than veganism - veganism excludes: fish, dairy, meat, eggs and paleo excludes: grains when an emphasis on eating vegetables in the place of grains. High-protein is rarely a problem, I don't even think it's been proven (it's very difficult to eat too much protein in particular) however high-carbs (vegan) can be, high fibre can certainly be, high sugar - obviously, and the low-carb diets are also bad. So obviously if you take it to an extreme it will be bad.

How does it fit in with an actual healthy diet?

Looking at this, I can see clearly where a vegetarian or vegan diet can very easily provide the right amounts of each food group. Based on this, how balanced is your idea of a healthy diet?

Well firstly, milk and dairy is not for everyone - it's for less than 50% of the world. Secondly, 50% of the world gets 50% of their calories from wheat, yet it should represent well less than this as you see on your plate.

I do have an aunt that has gluten intolerance, she can't eat bread, pasta, pastry, cereals, products containing soy, etc. That's why the paleo diet doesn't shock me, because I know that my aunt eats very well without that "food group". And it's the same for everyone who's gluten intolerant, they can't eat those foods.
