It makes sense to me that eating meat can improve the health of people just eating grains and tubers in the article. And from there, you can further improve your health by being even more precise about what you eat by following, for example, the whole food plant-based diet in that book. That eating meat is more nutritious than eating only carb crops isn't very applicable to anyone on HN, I don't think. We're kinda beyond that and should be looking for the next rung up on the ladder, like eating enough fiber—something few Americans do. We're too easily swept up in faction wars about food to have meaningful discussion and it muddies the water when you try to find good information. We'll argue about the health implications of meat and vegetables and whatever while having a coke and bag of chips next to the keyboard while pretending we're all min/maxing our health. Meanwhile, we ignore the fact that most people don't try to get anywhere near any of the so-called optimal diets we're so willing to argue about, and the distance from the average person's diet to those diets are probably a lot farther than the health impact between those diets.
