Correlation vs. Causation: Hunger and GMOs

First, notice the terminology shift. The claim is about hunger, an absolute lack of food. But the facts are about malnutrition and food insecurity,  terms which mean either not enough food, or food that doesn’t include all the necessary nutrients. In rural Iowa corn is probably cheap, so carbs are plentiful and the malnutrition is from a high-carb, low-fat, and low-protein diet.

Second, did food insecurity in the US increase by 57% because of GMOs? One of the first lessons in statistics is that correlation does not imply causation. Did the higher yields caused by GMOs cause an increase in food insecurity? Or would it have been even higher without them?
