On seeing the forest for the crunch
The primary reason people eat peanut butter is satiation. In terms of spreads, it is the unrivaled king of getting-you-not-hungry. Distant cousins hummus and Vegemite kiss its chunky feet. Would they swear fealty to a creamy spread? I think not, and here's why:
The extra peanut crunch helps fill you up. It's that simple.
First it slows down the mastication, which is a word that creamy loyalists probably don't even understand. It means to chew. You know, like what you do to pieces of substantial food that you put in your mouth.
But secondly, it's giving your hunger a little something extra. It's like butter with a Christmas bonus. What sort of Scrooge doesn't believe in Christmas bonuses? “No thank you, I would not like a Christmas bonus,” said no one ever.
