These are not my words. All I am arguing is that we should expect the simplest possible connection between nutrition and health. Although I do agree we should also understand the systematic effects of certain choices, we cannot make decisions if all these effects are aggregated haphazardly.

It would make sense if another study would combine the nutritional long-term effects, the societal costs, the availability of alternative sources of amino acids and other factors. Nevertheless, the conclusion: "Red meat consumption is unhealthy for individuals" should (imho) not consider the environmental effects. Principle of least astonishment.
