"Therefore, while the findings from PURE are largely consistent with the nutrition science and modern dietary recommendations to focus on protective foods, the public's understanding of healthy eating and relevant global policies have not yet caught up to this science," it states.theheart.org/Medscape Cardiology.
The scoring system assigned a value of 1 for each of the six health-food categories when individuals' intake exceeded the entire cohort's median intake. It assigned a 0 when intake was below the median. The total PURE healthy diet score consisted of the sum of the six values, with higher scores corresponding to a healthier diet. The mean score for cohort was 2.95.

In particular, improvement in diet score by one quintile was associated with significantly reduced risks for the following:Death or CV disease: HR, 0.93 Food labels in many countries mainly focus on"reducing certain nutrients as the end-all, be-all," Mente observed."Our findings can be used as a basis for recommendations regarding what a healthy diet should be globally and then modified for each region based on the specific types of foods that are available and affordable in each region."
Such studies"remind us of the continuing and devastating rise in diet-related chronic diseases globally, and of the power of protective foods to help address these burdens," the editorial continues."It is time for national nutrition guidelines, private sector innovations, government tax policy and agricultural incentives, food procurement policies, labelling and other regulatory priorities, and food-based healthcare interventions to catch up to the science.
