Today the British Medical Journal (BMJ) published an editorial that attacks the science behind the U.S. Dietary Guidelines report. It’s a surprising development for several reasons: the BMJ is a prestigious journal, yet the piece contains several basic factual errors, and it arrives just as meat and sugar industry lobbyists are seeking ways to derail the 2015 Dietary Guidelines for Americans, which government officials are now in the process of writing. The Guidelines have the potential to help prevent thousands of cancer and other chronic diseases.
The piece, written by a journalist who last year published a book called The Big Fat Surprise: Why Butter, Meat and Cheese Belong in the American Diet, claims the report by the Dietary Guidelines Advisory Committee (DGAC) “does not take into account all the relevant scientific evidence” and is marked by an “overall lack of sound and proper methods.” It goes on to list several specific studies that weren’t included, and to question the inclusion of observational evidence that does not meet what it considers “established” methods of analysis.
Within hours, the article’s misleading statements earned this swift and spirited rebuke on the website The Verge. That post addresses the BMJ article’s errors in great detail, and we at AICR encourage you to read it. Continue reading
It’s “Back to school” time and that brings challenges in keeping kids active and healthy in the 21st century. In decades past, school provided much more than academic education; it also provided an environment conducive to the development of social and life skills. Lessons learned on the playground included important social skills such as cooperation, teamwork, conflict resolution, and peer communication. Physical education class provided an outlet to release energy, and establish the important lifestyle habit of physical activity on a daily basis.

With recess and physical activity time being cut to make more time for classroom learning, the struggle to keep kids healthy and active is harder than ever before. The sad truth is kids are expected to spend the majority of their day “sitting”, contributing to skyrocketing childhood obesity rates and overall health concerns — including increased cancer risk — for our next generation.
That said, the challenges don’t end when the bell rings. Kids today have succumbed to the “technology takeover”, spending more time living in the “virtual” world than in the real one. While kids in previous generations would play outside afterschool until dinner time, kids today run home to video games, television shows, text messages, and social media, increasing the amount of time they are sedentary.
We all recognize the issues and we want to overcome them, but what motivates a child to want to be active? To answer this question we must remove our “adult” motivations (lose Continue reading
If you’re a reader of health news, there’s a good chance you’ve heard about the research looking at how office walking breaks can help your health. Now comes a small study suggesting that those breaks may also improve kids’ long-term metabolic health, which may lower their risk for adult cancers decades later.
The study found that children who break up their sitting with three minutes of walking every half hour had lower levels of blood glucose and insulin, compared to when they remained seated for three hours. It was published in the Journal of Clinical Endocrinology and Metabolism. High blood glucose and insulin are risk factors for metabolic syndrome, a cluster of conditions that also links to increased cancer risk among adults.
According to government data, more than one third of children and teens are overweight or obese. Kids who are overweight are more likely to be overweight adults, and excess body fat among adults is a cause of ten cancers.
The study included 28 healthy, normal-weight children who were assigned to one of two groups. Children in the first group remained sitting for three hours where they watched Continue reading
