To determine if self-reported fruit & vegetable consumption via the Fruit & Vegetable Consumption Evaluation Tool (FACET) questionnaire predicted Cardiovascular Disease (CVD) risk through analysis of its relationship with CVD risk markers. To additionally explore whether licensing behaviours effected self-reported fruit & vegetable consumption via the FACET pre- and post-trial intervention.
CVD risk marker variables were compared between high and low levels of fruit & vegetable consumption (cut-off: UK Government 5-a-day guidance).
Multivariable models were constructed for predictor variables with a coefficient p-value= ≤0.3 and fully adjusted for sociodemographic predictor variables including age, sex, smoking status, ethnicity and gross income and interaction terms determined a priori.
There was a statistically significant difference in the HbA1C concentration between those consuming high vs. low fruit and vegetables. The mean (SD) was 37.3 (3.73) mmol/mol in the low and 35.46 (3.43) mmol/mol in the high fruit & vegetable consumption group (p=0.048). These differences lay within the normal clinical range.
Age and sex were statistically significant in the relationship between Carotid Intima Media Thickness (cIMT) and fruit & vegetable consumption (Age: p=<0.001; Sex: p=0.001).
Multivariable models identified a significant relationship between cIMT and fruit & vegetable consumption where an increase in consumption by one portion of fruit & vegetables was associated with a decrease in cIMT (and therefore a reduction in CVD risk) of 0.032mm (p=0.034).
There was an association between higher fruit & vegetable consumption and lower CVD risk as determined by a small but biologically meaningful change in cIMT with number of portions of fruit & vegetables consumed. However, longer term studies with larger magnitudes of change in fruit and vegetable exposure are needed to reach a definitive conclusion.
There is a change in fruit & vegetable consumption behaviour when comparing individuals taking nutritional supplements vs. those not taking nutritional supplements meaning that supplements may prove beneficial in all individuals regardless of current behaviour.
