An increased consumption of fruits and vegetables (F&V) has been suggested as a way to limit, or even lower, energy and fat intakes. The present study examined the effects of incorporating F&V supplements into the diets of adults who reported consuming <240 g (three portions) of F&V per d on energy and fat intakes, and change in body weight, over 8 weeks using a randomised parallel design. Thirty-four males and twenty-eight females (age 42Â·6 (SD 11Â·1) years, BMI 23Â·7 (SD 2Â·7) kg/m2) were each provided with supplements of 0, 300 or 600 g F&V per d. Food, nutrient and energy intakes were measured before, during and at the end of the supplementation period using 7 d weighed records. Mean daily energy intakes were not different among the three groups before (PÂ¼0Â·151) or during the supplementation periods (PÂ¼0Â·407), although changes in energy intakes over the study period tended to be more positive with increasing amounts of F&V supplements (PÂ¼0Â·078). There was no difference in changes of body weights during the study (PÂ¼0Â·242). Carbohydrate (P,0Â·001), sugar (P,0Â·001), fibre (P,0Â·001) and weight of food consumed (PÂ¼0Â·022) increased in the treatment groups. There were no significant differences, or changes, in fat intakes among the three groups. Consumption of mandatory F&V supplements for 8 weeks produced beneficial changes in diet composition, but did not result in lower reported energy or fat intakes, and did not result in loss of body weight.
