> this just isn't a rational argument. Taurine, Creatine, Carnosine, and B12 are not found in significant amounts in plants. Heme Iron is much more bioavailable than Plant Iron or Iron supplements. Plant-based diets can also inhibit the absorption of many more nutrients, including Iron and B12. You cannot get the right type of omega-3 fatty acids through a normal plant-based diet, either, you must supplement it with an algae-based supplement. In fact, a lot of nutrients that are abundant in meat and readily absorbed and processed by our bodies probably needs to be supplemented with a pill to get enough of it on a vegan diet. Choline can be found in plenty of vegetables, but are you actually getting enough of it? Incorporating meat into the diet makes it very easy to get enough of many nutrients that our body needs without having to take a half dozen supplements. That doesn't even get into how a plant-based diet can negatively affect gut health and the composition of plants can inhibit nutrient activity and absorption. Nor does it get into how these diets can negatively affect children, either through the quality of nutrition derived from their mother's breast milk or from adhering to a plant-based diet in general.

Can't you have omega 3 with rapeseed? Also, you make a lot of statements without scientific backup. Afaik balanced pland based diet is healthy

  I have no dog in this fight, but will point out that asking for scientific backup and then using a word like "healthy" is kind of hypocritical. "Healthy" at best means nothing, and at worst is just a word to use to frame your agenda.

  Rapeseed oil has alpha-linolenic acid (ALA) which can be converted into eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), but the process to convert ALA to EPA/DHA is an inefficient one where only about 5-10% of what goes in gets converted. Much of the benefits of omega 3 are found in EPA/DHA and not in ALA, though ALA may also be beneficial. So, kind of? but not really? > Also, you make a lot of statements without scientific backup. This isn't hard to look up nor is it particularly controversial. > Afaik balanced plant based diet is healthy It can be. It's just way harder to get the nutrients in the right amounts when compared to someone who is eating meat. Meat obviously has its own issues, but it's undeniable that it's an incredible source of protein that has the right composition of amino acids and has higher bioavailability in the nutrients your body needs. No one is going to accidentally eat a healthy and balanced vegan diet, you will almost certainly become deficient in B12 and potentially a lot of other essential vitamins and minerals. You'll also have issues with amino acids. Meats have a more complete profile that is easily used and absorbed by the body. Individual plant proteins may lack specific ones and the amount and quality of them is lower. Plants also can contain many different antinutrients that make it more difficult for your body to absorb nutrients. This is why plant-based protein powders are a higher quality protein source for vegans than just eating plants.

When people talk about reducing meat for environmental reasons they are usually implicitly referring to red meat. Chickens are great, they consume food waste and produce eggs. Yes there are some people who think that the best way to save the planet is to drink as much almond milk as possible. But that is not the strongest form of the argument.

  The way to "fix" meat consumption is to ensure that the externalities are accounted for in their cost (which currently isn't). In fact, this applies to _everything_, not just red meat. Meat that has less externalities will surely be cheaper then - such as chicken/poultry, and even fish or insect proteins. The fact that the paid cost of red meat for a consumer is not reflective of their true cost is the meat of the issue to me.

Again, you don't have to convince me. I eat meat too. I agree, meat calories are higher quality for a variety of reasons -- you don't need to argue this point to me. My point is that these reasons are not essential reasons. You can survive without Taurine, Creatine, Carnosine because they are all synthesized by the body. Is it preferable to supplement with them in a diet? Yes. Are there more than a billion vegetarians on earth who don't supplement these? Also yes. We can and should accept both of these facts: 1) Meat is a better calorie source. 2) Meat is less efficient in terms of energy consumption and this is a problem. You can't disprove #2 by arguing about #1.
