It used to be fat, but now consumers are deciding on the healthfulness of a product based on its sugar levels. So says research in the Journal of Human Nutrition and Dietetics. The study, which surveyed 858 volunteers, included a choice-based questionnaire that used a traffic-light labeling system; packaged foods like cereals were assigned a color based on their nutritional makeup. Results showed that participants perceived red-light food with a high sugar content to be the worst for health and something to avoid, while foods with excess fat, saturated fat or salt were viewed as less off-putting.

While it’s good to see that people are becoming aware of the pitfalls of eating too much sugar, particularly sweeteners added to foods, it’s still important for consumers to have their guard up in relation to other potential concerns with packaged foods—like saturated-fat and sodium levels.
