Data from the Prospective Urban Rural Epidemiology (PURE) study highlight the disparity between healthy diet and lifestyle behaviors among affluent and underdeveloped nations. The consumption of fruits and vegetables increased among nations with a higher gross domestic product (GDP) and wealth index, but this was offset by an increase in the amount of energy obtained from total and saturated fats, as well as from protein.No "need" at all.
Dr Salim Yusuf (McMaster University, Hamilton, ON), the lead researcher of the PURE study, said the study, which describes an "epidemiological transition," might help shift global food policies so that countries subsidize the production of fruits and vegetables rather than meat and dairy. In addition, the study highlights an insufficient policy approach when it comes to increasing physical-activity levels.
"In relation to physical activity, sure, we can tell people to be active 30 minutes a day for five days a week, but it's only a tiny drop in the ocean," Yusuf told heartwire. "We've talked about changing the environment by changing our modes of transportation, but what do you do about somebody like you and me who have sedentary jobs? How do we make our jobs more active?"
Regarding the need for change, Yusuf said there is a need for greater investment to understand the societal determinants of health.
Just a need to hold people accountable for their illnesses of choice.
Then watch the "environment" change.
