Portion, package or tableware size for changing selection and consumption of food, alcohol and tobacco
Hollands and colleagues produced the Cochrane review of whether the size and shape of portions, packages and tableware change how much people consume, covering food, alcohol and tobacco, in adults and children, across laboratory and real-world settings. Cochrane reviews apply the strictest standards in this field, including only randomised trials and assessing the risk of bias in each. The conclusion supports the central claim: people exposed to larger portions, packages or items of tableware consume more, and the effect is consistent enough to make product size a legitimate target for public health policy. The review also examines which study, intervention and participant characteristics change the size of the effect. It is the reference to cite for the portion-size claim, in preference to any single striking experiment, and particularly in preference to work from laboratories whose findings have since been withdrawn.
