For starters, wheat is not the same today. It has been hybrid over time to resist fungus, grow more quickly, and be more pliable for industrial bread baking. 50 years or so ago, wheat contained only five percent gluten. Today, it is 50 percent gluten.
The food industry’s concern for production efficiency and perception of consumer demands has focused on the bottom line with the usual disregard to the negative health consequences of fellow humans. Breads and other baked goods are hastily produced with additives and short cuts that are actually toxic.
In the UK, some of Europe, and North America, slightly different high speed methods of baking evolved over time. By adding “improvers” with usually toxic additives and mixing the dough violently, loaves of bread could be baked, cooled, and packaged within a few short hours.
