"Want to end obesity?" asks Philip James of the London School of Hygiene and Tropical Medicine and President of the International Study for the Study of Obesity. "Then talk to the ministries of finance, not health.

The impact of health education is zero."

Christopher Wanjek of LiveScience's Bad Medicine writes about a meeting of nutrition experts in Rio de Janeiro on how to end the rising global obesity:

The food industry is making us fat, according to James, and efforts to educate the public on proper nutrition or to ask industry to voluntarily reduce unhealthy ingredients such as sugar, salt, fat and myriad additives is "a load of diverting, delaying rubbish," he said. Government-initiated economic policies are needed to make healthy food affordable.

The culprit is "ultraprocessed" food, which are nutrient-poor and calorie-rich, and some experts believe that the cure is government regulation: Link (Photo: Shutterstock)
