Soda Politics: Taking on Big Soda (And Winning)

by Marion Nestle

Oxford University Press, 528 pp.

Excess sugar intake is killing Americans. But a few giant, consolidated beverage companies keep squashing reform efforts.

From the latest Taco Bell concoction to the lack of fresh produce in many low-income communities across the country, there's no shortage of targets to blame for America's poor national diet. But in recent years, many public health campaigns have zeroed in on a single enemy: soda. And there's good reason for this. Drinking soda is entirely optional (there's no medical reason to consume sugar water). It is remarkably common (around 50 percent of Americans regularly consume non-diet sodas). And the industry has huge political sway (Big Soda contributes millions of dollars a year to campaigns and candidates).

Now Marion Nestle (no relation to the Nestle food company), a nutritionist and professor of sociology and food systems at New York University, has written what she hopes will serve as a guide to effectively fighting the soda industry.

But the average American isn't consuming sugar in moderation. American children on average consume 16 percent of their daily calories in added sugars, and for adults the average is 13 percent. That's way higher than most health experts' recommendation, that sugars should comprise at most 10 percent of daily calories. High sugar consumption has been associated with higher risk for heart disease, diabetes, and obesity.

The attack on Big Soda will be familiar to many readers. The issue made headlines in 2012 when then New York City Mayor Michael Bloomberg attempted to pass a 1-cent-per-ounce soda tax. Many critics dismissed that attempt, along with Bloomberg's effort to cap the size of fountain soda containers, as "nanny statism." But soda taxes have found an audience elsewhere. Earlier this year, Berkeley, California, implemented a i-cent-per-ounce tax on...
