When applied at scale, UK researchers say food calorie labeling could lead to “potentially meaningful impacts” on population health. After reviewing 25 randomized control trials, the team found that calorie labeling led to small reductions in calories selected (1.8%) and consumed (5.9%). The researchers say the evidence is most substantial when considering product purchases, but that evidence for consumption suggests a similar effect. They caution that insufficient evidence exists to estimate the impact of calorie labeling on alcoholic drink consumption.
