Stung by the rejection, Cadbury Schweppes in 2004 turned to a food-industry legend named Howard Moskowitz. Moskowitz, who studied mathematics and holds a Ph.D. in experimental psychology from Harvard, runs a consulting firm in White Plains, where for more than three decades he has “optimized” a variety of products for Campbell Soup, General Foods, Kraft and PepsiCo. “I’ve optimized soups,” Moskowitz told me. “I’ve optimized pizzas. I’ve optimized salad dressings and pickles. In this field, I’m a game changer.”
In the process of product optimization, food engineers alter a litany of variables with the sole intent of finding the most perfect version (or versions) of a product. Ordinary consumers are paid to spend hours sitting in rooms where they touch, feel, sip, smell, swirl and taste whatever product is in question. Their opinions are dumped into a computer, and the data are sifted and sorted through a statistical method called conjoint analysis, which determines what features will be most attractive to consumers. Moskowitz likes to imagine that his computer is divided into silos, in which each of the attributes is stacked.
But it’s not simply a matter of comparing Color 23 with Color 24. In the most complicated projects, Color 23 must be combined with Syrup 11 and Packaging 6, and on and on, in seemingly infinite combinations. Even for jobs in which the only concern is taste and the variables are limited to the ingredients, endless charts and graphs will come spewing out of Moskowitz’s computer. “The mathematical model maps out the ingredients to the sensory perceptions these ingredients create,” he told me, “so I can just dial a new product. This is the engineering approach.”
Moskowitz’s work on Prego spaghetti sauce was memorialized in a 2004 presentation by the author Malcolm Gladwell at the TED conference in Monterey, Calif.: “After . . . months and months, he had a mountain of data about how the American people feel about spaghetti sauce. . . . And sure enough, if you sit down and you analyze all this data on spaghetti sauce, you realize that all Americans fall into one of three groups. There are people who like their spaghetti sauce plain. There are people who like their spaghetti sauce spicy. And there are people who like it extra-chunky.
And of those three facts, the third one was the most significant, because at the time, in the early 1980s, if you went to a supermarket, you would not find extra-chunky spaghetti sauce. And Prego turned to Howard, and they said, ‘Are you telling me that one-third of Americans crave extra-chunky spaghetti sauce, and yet no one is servicing their needs?’ And he said, ‘Yes.’ And Prego then went back and completely reformulated their spaghetti sauce and came out with a line of extra-chunky that immediately and completely took over the spaghetti-sauce business in this country. . . . That is Howard’s gift to the American people. . . . He fundamentally changed the way the food industry thinks about making you happy.”
Well, yes and no. One thing Gladwell didn’t mention is that the food industry already knew some things about making people happy — and it started with sugar. Many of the Prego sauces — whether cheesy, chunky or light — have one feature in common: The largest ingredient, after tomatoes, is sugar. A mere half-cup of Prego Traditional, for instance, has the equivalent of more than two teaspoons of sugar, as much as two-plus Oreo cookies.
It also delivers one-third of the sodium recommended for a majority of American adults for an entire day. In making these sauces, Campbell supplied the ingredients, including the salt, sugar and, for some versions, fat, while Moskowitz supplied the optimization. “More is not necessarily better,” Moskowitz wrote in his own account of the Prego project. “As the sensory intensity (say, of sweetness) increases, consumers first say that they like the product more, but eventually, with a middle level of sweetness, consumers like the product the most (this is their optimum, or ‘bliss,’ point).”
I first met Moskowitz on a crisp day in the spring of 2010 at the Harvard Club in Midtown Manhattan. As we talked, he made clear that while he has worked on numerous projects aimed at creating more healthful foods and insists the industry could be doing far more to curb obesity, he had no qualms about his own pioneering work on discovering what industry insiders now regularly refer to as “the bliss point” or any of the other systems that helped food companies create the greatest amount of crave. “There’s no moral issue for me,” he said. “I did the best science I could. I was struggling to survive and didn’t have the luxury of being a moral creature. As a researcher, I was ahead of my time.”
Moskowitz’s path to mastering the bliss point began in earnest not at Harvard but a few months after graduation, 16 miles from Cambridge, in the town of Natick, where the U.S. Army hired him to work in its research labs. The military has long been in a peculiar bind when it comes to food: how to get soldiers to eat more rations when they are in the field. They know that over time, soldiers would gradually find their meals-ready-to-eat so boring that they would toss them away, half-eaten, and not get all the calories they needed. But what was causing this M.R.E.-fatigue was a mystery.
“So I started asking soldiers how frequently they would like to eat this or that, trying to figure out which products they would find boring,” Moskowitz said. The answers he got were inconsistent. “They liked flavorful foods like turkey tetrazzini, but only at first; they quickly grew tired of them. On the other hand, mundane foods like white bread would never get them too excited, but they could eat lots and lots of it without feeling they’d had enough.”
This contradiction is known as “sensory-specific satiety.” In lay terms, it is the tendency for big, distinct flavors to overwhelm the brain, which responds by depressing your desire to have more. Sensory-specific satiety also became a guiding principle for the processed-food industry. The biggest hits — be they Coca-Cola or Doritos — owe their success to complex formulas that pique the taste buds enough to be alluring but don’t have a distinct, overriding single flavor that tells the brain to stop eating.
