Now this here is some SCIENCE.

It is perfectly engineered to be consumed over and over and over.

It's not food. It's food-ertainment.

The feel of fat:

Mr. Witherly says that to maximize the pleasure in snacks, the goal is to deliver half the calories through fat, and Nacho Cheese Doritos hit this mark precisely. Scientists say fat is experienced not as a basic taste like sweetness or bitterness, but rather as a sensation, with a mouth feel that has all the power of sugar or salt. Fat in food is detected by the trigeminal nerve, which conveys the signal straight to the brain’s pleasure center.

The chip is just a vehicle for the flavor:

The inventor of Doritos envisioned this snack in 1964 as a marketing powerhouse that could deliver endless varieties of new flavors. But none of the formulations would surpass Nacho Cheese, whose irresistible taste sent Doritos into the processed food hall of fame, and more recently into a partnership with Taco Bell.

The melting sensation tricks the brain:

When fat-laden snacks melt in the mouth, the brain thinks that the calories have disappeared, too, in what food scientists call “vanishing caloric density.” This tends to delay the feeling of fullness.

The flavor powder further tricks the brain:

The blend of ingredients in Nacho Cheese is given one of the finest grinds in food processing: flour grinding, which creates a powder that fills every nook and cranny on the chip. This maximizes the amount that will contact saliva. Intentional or not, one byproduct is the powder left on your fingers.

Licking the dust from the fingers in its pure form, without the chip to dilute the impact, sends an even larger flavor burst to the brain.

Garlic is a powerful memory stimulant:

There is also garlic powder, which has the powerful savory flavor known as umami. The “long hang time” of flavors like garlic creates a lingering smell that stimulates memories (and contributes to “Dorito breath”).

Salt tricks the brain into eating more:

It’s no accident that salt makes three separate appearances in the list of ingredients. Salt delivers what food companies call “flavor burst.” It dissolves in saliva, igniting the salt receptors on the tongue. They send signals that excite the pleasure center of the brain, which encourages us to eat more.

MSG amplifies flavors:

By itself, monosodium glutamate has little taste. But when we tried this white powder mixed with salt, we could almost feel our brains start to sizzle. Despite complaints that it has side effects, MSG is still widely used in processed foods because it powers up other flavors, especially savory ones. Nacho Cheese chips also have two ingredients that crank up the flavor even more: derivatives from the nucleotide family called disodium inosinate and disodium guanylate. When we tasted this pair along with MSG and salt, Mr. Witherly tossed back his head and cried, “Wow! Oooh! Water!”

It's all chemicals.

The forgettable flavor is why you can't eat just one.

Despite the powerful tastes in Nacho Cheese, the Doritos formula balances them so well that no single flavor lingers in the mind after you’ve eaten a chip. This avoids what food scientists call “sensory specific satiety,” or the feeling of fullness caused by a dominant flavor. Would you eat a whole bag of rosemary chips? With Doritos, you go back for more.

Coca-Cola has a flavor that is similarly ambiguous and forgettable.

Research has shown that consumers are attracted to bright colors:

Doritos have three artificial colorings: two different yellows and a red.
