10 Things the Food Industry Doesn't Want You to Know

Video: Is Your Child Overweight?

With America's obesity problem among kids reaching crisis proportions, even junk food makers have started to claim they want to steer children toward more healthful choices. In a study released earlier this year, the Centers for Disease Control and Prevention reported that about 32 percent of children were overweight but not obese, 16 percent were obese, and 11 percent were extremely obese. Food giant PepsiCo, for example, points out on its website that "we can play an important role in helping kids lead healthier lives by offering healthy product choices in schools." The company highlights what it considers its healthier products within various food categories through a "Smart Spot" marketing campaign that features green symbols on packaging. PepsiCo's inclusive criteria—explained here—award spots to foods of dubious nutritional value such as Diet Pepsi, Cap'n Crunch cereal, reduced-fat Doritos, and Cheetos, as well as to more nutritious products such as Quaker Oatmeal and Tropicana Orange Juice.

But are wellness initiatives like Smart Spot just marketing ploys? Such moves by the food industry may seem to be a step in the right direction, but ultimately makers of popular junk foods have an obligation to stockholders to encourage kids to eat more—not less—of the foods that fuel their profits, says David Ludwig, a pediatrician and the co-author of a commentary published in this week's Journal of the American Medical Association that raises questions about whether big food companies can be trusted to help combat obesity. Ludwig and article co-author Marion Nestle, a professor of nutrition at New York University, both of whom have long histories of tracking the food industry, spoke with U.S. News and highlighted 10 things that junk food makers don't want you to know about their products and how they promote them.

1. Junk food makers spend billions advertising unhealthy foods to kids.
According to the Federal Trade Commission, food makers spend some $1.6 billion annually to reach children through the traditional media as well the Internet, in-store advertising, and sweepstakes. An article published in 2006 in the Journal of Public Health Policy puts the number as high as $10 billion annually. Promotions often use cartoon characters or free giveaways to entice kids into the junk food fold. PepsiCo has pledged that it will advertise only "Smart Spot" products to children under 12.

2. The studies that food producers support tend to minimize health concerns associated with their products.
In fact, according to a review led by Ludwig of hundreds of studies that looked at the health effects of milk, juice, and soda, the likelihood of conclusions favorable to the industry was several times higher among industry-sponsored research than studies that received no industry funding. "If a study is funded by the industry, it may be closer to advertising than science," he says.

3. Junk food makers donate large sums of money to professional nutrition associations.
The American Dietetic Association, for example, accepts money from companies such as Coca-Cola, which get access to decision makers in the food and nutrition marketplace via ADA events and programs, as this release explains. As Nestle notes in her blog and discusses at length in her book Food Politics, the group even distributes nutritional fact sheets that are directly sponsored by specific industry groups. This one, for example, which is sponsored by an industry group that promotes lamb, rather unsurprisingly touts the nutritional benefits of lamb. The ADA's reasoning: "These collaborations take place with the understanding that ADA does not support any program or message that does not correspond with ADA's science-based healthful-eating messages and positions," according to the group's president, dietitian Martin Yadrick. "In fact, we think it's important for us to be at the same table with food companies because of the positive influence that we can have on them."
