Food is measured in calories. People sometimes count calories and cut calories, and this week’s Please Explain is all about what calories are, how they’re measured, how we burn them, and if they differ from food to food. Joining us are: Dr. Kelly D. Brownell, Dean of the Sanford School of Public Policy and Professor of Public Policy at Duke University. And Russell Rising, Research Associate in the Metabolic Laboratory at the Obesity Research Center at St. Luke's-Roosevelt Hospital.
Walt Disney is the latest company to jump on the childhood anti-obesity band wagon. Today Disney will announce a new initiative to advertise healthier food products on all its media platforms for children. The company says that ads for sugary cereals and junk foods will eventually be phased out, and by 2015 all companies advertising food products with Disney will be required to comply with new nutritional standards.
Ever since Joseph Priestly discovered how to "impregnate water with fixed air" in the 18th century, carbonated beverages have been ubiquitous. Sodas have been used to cure diseases, fight alcoholism, and spread American culture around the globe. On this week's Please Explain, we’ll find out what soda is, what’s in it, and when it became so popular. We’re joined by Dr. Kelly Brownell, the co-founder and director of the Yale Rudd Center for Food Policy and Obesity, and Darcy O'Neil, beverage master and author of the book Fix the Pumps, a history of soda from the 18th century to the present.
