« There are no standardised serving/portion sizes deﬁned for foods consumed in the European Union (EU). Typical serving sizes can deviate signiﬁcantly from the 100 g/100 ml labelling speciﬁcation required by the EU legislation. Where the nutritional value of a portion is speciﬁed, the portion size is determined by the manufacturers. Our objective was to investigate the potential for standardising portion sizes for speciﬁc foods, thereby ensuring complementarity across countries. We compared portion size for 156 food items measured using a food frequency questionnaire across the seven countries participating in the Food4me study.
The probability of consuming a food and the frequency of consumption differed across countries for 93% and 58% of the foods, respectively. However, the individual country mean portion size differed from the average across countries in only 16% of comparisons. Thus, although dietary choices vary markedly across countries, there is much less variation in portion sizes. Our results highlight the potential for standardisation of portion sizes on nutrition labels in the EU. »
