Similar situations have been seen around the world, when people switch from traditional, unprocessed foods to processed, "modern" diets. Often, significant degeneration has taken place within one or two generations, and people of different towns or islands were found to have radically different states of health depending on whether they continued to eat traditional foods, or adopted modern products. In conclusion, the overzealous modernisation of the past century really does need to be tempered by an acknowledgement of the nature of our bodies; we are not meant to be entirely dependent on machines.
