It is a sustained continual onslaught on animal protein. This then gets into the psyche so that the average person believes there is a serious problem. The proposed diet offers a fig leaf meat / fish whilst promoting a recipe for high blood sugar, high insulin and digestive issues for many. Red meat consumption is down already with the rise in poultry. I am yet to see a human dietary intervention that works better than nature. None of the sweeter fruit is the same as the original, flour is not the same etc.
A truthful discussion is required, if meat causes 15% of the emissions, is it just me, but why not focus on the 85%....In addition we know that "their" method depletes soil, so is it over simplistic to increase animal numbers (more jobs), in Britain for example use some of the vast land masses for cows, and where this is not possible sheep who can cope with poorer quality soil. When I look at the red meat section in supermarkets there is plenty in the UK, so worldwide is some of the issue a distribution / fair share problem. Meat and 2 veg (low GI) is a much better plate. Clever people always put up straw man arguments for their way of eating, that anecdotally correlates with "our" worst period of lifestyle diseases in history - no society which has imported the soy, grains and over processed foods, can demonstrably show better lifestyle disease numbers.
Honesty is the best policy, let's get real facts on the table, no twists and turns, no relative risks, no hidden agendas or industry backings.
