The impact of Cochrane evidence on portion sizes and food consumption

The Cochrane Review, Portion, package or tableware size for changing selection and consumption of food, alcohol and tobacco, published in the Cochrane Library by the Cochrane Public Health Group found significant evidence that people consume more food or non-alcoholic drinks when offered larger sized portions or when they use larger items of tableware.

Since its publication, this Cochrane Review has been one of the most important and highly cited public health stories worldwide, and has informed Public Health England’s report on sugar reduction.
