„...understated how healthy a vegan diet is...“ One question always crosses my mind when I hear this, maybe someone knows an answer here on HN.<p>It seems easy to tell the negative effects of eating meat (might cause cancer, etc). But are all the effects of not eating animal products at all in the long-term well known? And I don&#x27;t mean not eating animal products for 1 year or 10 years but for multiple generations.<p>Will people who have not eaten animal products for 1000 years still have a life expectancy similiar to the general population (I guess animal product-eaters)? Will they have more&#x2F;less diseases, higher&#x2F;lower IQ, etc.
