Pure fruit juice (PFJ) contains naturally occurring ‘free’ sugars, providing 8–14 % of daily intakes depending on the age group(Reference Bates2). Free sugars are now the target of a challenging average population intake of ⩽5 % energy(1), i.e. around 30 g daily for an adult. While concerns have been raised about the sugar content of PFJ, 150 ml counts as one portion of fruit and PFJ continues to be acknowledged as a valid option within 5-A-Day messaging(3).

A secondary analysis was conducted on 2967 participants aged 11 to 99 years from the National Diet and Nutrition Survey (2008–2012) as this is the age range to which the 5-A-day message applies. Dietary data were collected using a 4-day food record with estimated portion sizes. The aim of the analysis was to examine associations between PFJ consumption and 5-A-Day compliance, whole fruit and vegetable (F&V) consumption, and non-milk extrinsic sugar (NMES) intakes (similar to free sugars).

Mean PFJ consumption was 83 ml/d in participants aged 11–18 y (53 % were consumers) and 52 ml/d in those aged 19–64 y (39 % were consumers). Orange and apple were the most commonly consumed PFJs. After grouping participants by PFJ intake, associations were investigated with whole F&V consumption (excluding composite dishes), as well as with NMES intakes as a proportion of daily total energy (see table below).

All linear associations were statistically significant (ANOVA) suggesting that higher PFJ consumption was associated with higher intakes of F&V, but also higher NMES intakes. The small differences in NMES intake between non-consumers and those who consumed ⩽150 ml PFJ were only statistically significant in adults. On a positive note, PFJ consumers were significantly more likely to reach 5-A-DAY (39 % vs. 23 % of non-consumers). Previous work has shown that PFJ consumers tend to have a lower BMI than non-consumers(Reference Gibson4).

In conclusion, PFJ intake appears to be a marker of a ‘health-conscious’ diet as well as a distinct contributor to 5-A-day (mean from PFJ = 0·4 portion in adults and 0·6 portions in young people). Consuming up to 150 ml/d PFJ marginally increased NMES in adults but not in young people, suggesting this level of intake offers a benefit in terms of 5-A-day compliance, particularly since only 9 % of children and 32 % of adults achieve the F&V target.
