      Humans are omnivores, and have been for the lifespan of our species

      There are a number of important nutrients that humans get from animal products that are difficult to get from plant-based sources, including vitamin B12, which is not present in land-based plant species (I’m not sure whether red algae counts as a plant, so I’m playing it safe with land-based)

        That being said, a lot of people (myself included) eat far more animal products, particularly meat, than needed

        There are a number of factors at play there, including government subsidies for feed crops and meat production artificially driving up its availability

          From the research I’ve done, I think the most responsible diet would be a mostly plant-based one, but with the addition of chicken eggs from a responsible source, along with a basic mineral supplement for calcium/iron

        This is one argument @darganon. We need nutrients from a variety of things. We can live without some of them but that can come at the cost of health later in life e.g Vegetarian women more likely to fracture hips in later life.

        Furthermore:

        animal-source foods (ASFs) are dense in bioavailable vitamins and minerals. ASFs are the only intrinsic food source of vitamin B12 [7] and contain more bioavailable forms of vitamins A and D, iron, and zinc than plant source foods (PSFs)

        Source

        Then there’s land-use:

        • 86% of the global livestock feed intake in dry matter consists of feed materials that are not currently edible for humans

        • Contrary to commonly cited figures, 1 kg of meat requires 2.8 kg of human-edible feed for ruminants and 3.2 for monogastrics

        • Livestock consume one third of global cereal production and uses about 40% of global arable land

        Source

        It wouldn’t surprise me if we evolved to have balanced diet from multiple sources because they have the nutrients we require. We most likely don’t need all the meat we’re eating and we do a terrible job in developed countries with reducing waste. But just like a purely meat based diet, a purely plant based diet is just one of the extremes. To each their own though.

      Eh, the real counter argument isn’t about their beliefs. That’s fine. Most of it is sound logic.

      The problem is their insistence on not only being right, but being better.

      The part that makes it silly is the assumptions that chain from there being a right and wrong about what we do with dead animals. It’s a corpse. What matters is how we treat the living animals, and they are utterly convinced that not only is their way the one true way, but that anyone who believes otherwise is a bad person. I’ve been using this troll for something like a decade, and it never, ever fails to draw someone throwing around terms like evil, heartless, cruel, psychopath, etc.

      That’s the thing to counter argue, not any of the ecological stuff, or the need to treat living things well.

      That assumption of moral authority is the point of the troll.

      Why do you need a counter argument? X being valid/true has no impact on whether Y is valid/true. Attack an argument on the merits of the argument, not on the lack of merits of an alternative.

      That said, the main argument in favor of eating meat is that humans evolved to eat meat, so our bodies need nutrients that are easier to find in meat (e.g. certain types of protein). However, meat was a much smaller portion of our diets in the past than it is today, so this argument is actually in favor of eating less meat, but still including meat in your diet.

      The concepts of veganism aren’t really at odds with meat consumption. In many (most?) cases, vegans care most about the ethical treatment of animals (as opposed to vegetarians, who are more often motivated by nutrition), and our current meat processing industry is a lot less ethical than it was hundreds or thousands of years ago when most meat was either free range or wild. So I think it’s totally reasonable to take a middle ground and defend meat consumption on nutritional grounds while also defending veganism on ethical grounds.
