I know, right? Let me help you out with that.

A ton is 907 kg approximately, and the weight of a cup of blueberries, while varying, is around 148 g or 0.148 kg.

That means the above recipe calls for around 6128 cups of blueberries. And at 3.6 g per cup of blueberries that’s ~22000 g of fiber or 628 times your recommended daily intake for men, or 880 for women!
