“Scientists have offered a number of explanations — including the possible economic ramifications of the 2007 financial crisis, the increased consumption of unhealthy food, or even a shift from meat to plant-based diets, while noting that such theories are speculative at this stage.”
How much do you want to bet it’s from unhealthy food and the shift from meat to plant/based diets? (Isn’t that what happened when we moved from hunter/gatherers to farmers? ) And if they find that to be true, would the truth be allowed to be told?
Not usually a conspiracy theorist, but dietary science has moved me in that direction.
