The National Academy of Sciences in Washington, D.C., advises the nation on science, engineering, and medicine, and their website allows the general public to be privy to their findings. The Institute of Medicine of the National Academies has released on their website a Phase I report of their recent study on "Front-of-Package Nutrition Rating Systems and Symbols". Visitors can find the full Report on the right side of the page, and can be read online or downloaded as a PDF, both for free. A paperback version of the report can also be ordered for a charge. Visitors interested in a "Report Brief" or "Press Release" can view one in PDF or HTML. One of the most important things the report concludes is that due to the epidemic of obese Americans, "it would be useful to display calorie and serving size information prominently in front-of-package symbols." This would show the importance of calories in weight control. Visitors interested in receiving regular e-mails about the Institute of Medicine's work can sign up under the heading "Stay up to date!" on the right-hand menu.
