you can make a case that people can survive in really remarkable health with diets that look nothing like one another in other words you can look at somebody eating a really well formulated strict vegan diet where they're not getting any animal protein which clearly our ancestors all had animal protein whenever they could um they're often protein a little protein malnourished but they're very healthy yeah and similarly look at the opposite end of that spectrum you can look at somebody on a ketogenic diet who you know the only thing they would have in common between that other person is probably a lot of leafy vegetables but other than that it's a much higher fat higher protein diet they can be very healthy yeah
