In most developed countries people eat lots of fiber. Like just unbelievable amounts of meat, more than ever before in human history and prehistory.
What are you talking about?? Meat contains no fiber. The primary fiber source is plant-based foods (e.g., vegetables). So modern populations eating lots of meat means they're getting little to no fiber.
