Food marketers have an opportunity to help consumers who are seeking healthy foods by providing easy-to-understand nutrition information on-pack, according to a new report from Nielsen.  The research company polled 25,000 consumers in 53 nations and found that more than half consider themselves overweight and even more (59%) admit having trouble reading nutrition labels.   Nielsen’s advice is to simply labels and make them more consumer friendly – think USA Today style.  The findings also reveal consumer skepticism over such better for you claims as “low fat” and “all natural.”
