That is a lot no matter how you look at it though. If you assume someone eats 2,000 calories a day and 60,000 calories a month of only this one product, that would still be providing a month worth of food for 15 billion people.
I think a person eats 2,000 kilocalories a day and 2,000,000 calories per day.
When one person eats 2M calories a day, selling trillions of calories is suddenly not so hard!
Ah, perhaps you're right. I assumed by the uppercase 'C' it was kilocalories, but maybe it was just how it was formatted.
