Abstract Background The effect of personalised nutrition advice on discretionary foods intake is unknown. To date, two national classifications for have been derived. This study examined changes in and beverages following a intervention using these classifications. Methods Participants were recruited into 6-month RCT across seven European countries (Food4Me) randomised to receive generalised dietary (control) or one three levels (based diet [L1], phenotype [L2] genotype [L3]). Dietary was derived from an FFQ. An analysis covariance used determine effects at month 6 between (overall by levels) control i) percentage energy items ii) contribution total fat, SFA, sugars salt intake, defined Food Standards Scotland (FSS) Australian Guidelines (ADG) Results Of the 1607 adults baseline, n = 1270 (57% female) completed intervention. Percentage FSS lower vs (19.0 ± 0.37 21.1 0.65; P 0.005). (31.2 0.59 32.7 0.59; 0.031), fat (31.5 33.3 0.021), SFA (36.0 0.43 37.8 0.75; 0.034) (31.7 0.44 34.7 0.78; < 0.001) ADG control. There greater reductions those L3 L2. Conclusions Compared with advice, achieved when classification included all high added salt. Future approaches may be target foods.
