" In her most recent project, she tested 356 children, ages five to ten, who were brought to Monell to determine their “bliss point” for sugar31. The bliss point is the precise amount of sweetness—no more, no less—that makes food and drink most enjoyable. She was finishing up this project in the fall of 2010 when she agreed to show me some of the methods she had developed. Before we got started, I did a little research on the term bliss point itself. Its origins are murky, having some roots in economic theory. In relation to sugar, however, the term appears to have been coined in the 1970s by a Boston mathematician named Joseph Balintfy, who used computer modeling to predict eating behavior. The concept has obsessed the food industry ever since. "
