The scientific rationale for the soft-drink regulation is questionable:
For one, the justification for the proposed rule appears to rest largely on a claim that Americans are obese because we “consume 200-300 more calories daily than 30 years ago, with the largest single increase due to sugary drinks.” But nothing in the one citation on which that claim is based, a 2005 article in the Annual Review of Public Health, directly supports this bold claim. Rather, the authors of that study looked at the results of five earlier studies that showed “caloric intake rose by roughly 12% (300 calories per day) between 1985 and 2000, mainly because of increased consumption of grains, added fats, and added sugars.”The study can be found here.
