"It's worth noting for anyone that advocates this sort of diet that it is a luxury." In what way is this diet a luxury? Some of the ingredients are not found in supermarkets and so not easily available. But beans, lentils, mushrooms, fruits are readily available at your local supermarket if you live Europe or the US. Want to know what is a luxury? The world's consumption of meat, especially in Europe and US. I'm a meat eater, but we are eating more meat now that in any other time in history. We think such cheap and plentiful meat (on a daily basis for so many people) is how it's always been, but it's only thanks to industrial-scale farming we can eat meat so cheaply and with such abundance. And what a bunch of hypocrites we are on the subject (myself included). So many of us won't even consider reducing our meat consumption despite the proven role of animal agriculture in contributing to climate change.
