The strongest indicator that fast food is becoming the dominant source of nutrition in America is the dramatic growth in both the number and revenue of the various fast food chains. For instance, in 2009, McDonald's took in 22.6 billion dollars in the US. When you consider that the US has a population of about 300 million ,that works out to about $75 per person! Add to that Burger King's take of $2.5 billion (about $8 per person), $2.5 billion at Wendy's, $1.9 billion at Taco Bell, $1.4 billion at Domino's Pizza, $1.3 billion at Arby's, $5.5 billion at Dunkin' Donuts, $10.7 billion at Starbucks, and $9 billion at Subway, and you begin to get the picture of how we spend many of our food dollars.

Other indicators are the presence of fast food options as part of hot lunch offerings at schools and in college cafeterias, and the constant presence of ready-to-eat food pretty much everywhere and at all hours of the day or night. Nutritionists say that the human taste sense prefers a combination of sweet, fat, and salt above all others. Fast food restaurants consistently offer this combination, which makes fast food almost addictive.
