More easily available carbon (from CO2) while lowering available minerals (from lower transpiration and thus lower mineral transport from the soil) have probably contributed by making foods less nutritious per serving and more balanced towards starches, sugars and fats. For example, vitamin content of many vegetables has decreased by thirty percent or more since the introduction of GM foods.
However, modern agricultural practices and food processing also HAS to take a bit part of the blame.
