We live in a modern America where even children as young as two know what they want and aren't afraid to ask. However, when combined with the colorful world of children's advertising, that assertiveness can get dangerous. From the Yale Rudd Center for Food Policy and Obesity's study on fast food: "The average preschooler (2-5 years) saw 2.8 TV ads for fast food every day in 2009; children (6-11 years) saw 3.5; and teens (12-17 years) saw 4.7." Then, "Forty percent of parents reported that their child asks to go to McDonald’s at least once a week; 15% of preschoolers ask to go every day." They probably heard the McRib is back.

The study also finds that once a child's tantrum is traumatizing enough to force the parents to actually take them to a fast food joint, there's not much there that won't be contributing to heart problems later in the kid's life. Despite the recent push toward healthy meal combos in fast food restaurants, the study found that just 12 of the 3,000 kids meal combos tested met their nutrition criteria for preschoolers, and just 15 met the criteria for older kids. The healthiest meal was Subway's veggie delight sandwich on wheat bread with no cheese, with sides of apple slices and juice (285 calories total). The worst came from KFC, a popcorn chicken combo with a biscuit, string cheese and Mountain Dew packs 840 calories and a whopping 1,610 mg of sodium. Mountain Dew? Ugh, we'll take the crab juice.

In New York City, four out of every ten school-aged kids are overweight or obese, and those who are tend to get worse grades than the kids who are in shape. The Bronx also has the highest rate of obesity of the five boroughs, where residents are 85% more likely to be obese than Manhattanites.
