(OR24-07-23) Effect of 100% Orange Juice and a Volume-Matched Sugar-Sweetened Drink on Satiety and Food Intake in Normal Weight Adults

Objectives: Dietary guidelines often group 100% fruit juices together with sugar-sweetened beverages as sources of free sugars to reduce. The objective of this study was to determine the effect of consuming 100% orange juice (OJ) compared to an orange-flavoured sugar-sweetened drink (OD) or the water control on subjective appetite, food intake (FI) and rest-of-day energy intake (EI) in normal-weight adults.

Methods: Using a within-subjects, repeated-measures design, 36 participants (age: 26.8 ± 0.9 y; BMI 22.0 ± 0.3 kg/m2) completed three test sessions at least five days apart. Following an overnight fast and a standardized breakfast, participants consumed, in random order, three isovolumetric (240 ml) test treatments as follows: (a) 100% OJ, (b) OD, or (c) water control. Subjective appetite, treatment pleasantness and perceived sweetness were evaluated using visual analogue scales. Short-term FI at 60 min was assessed at an ad libitum pizza lunch. Rest-of-day EI was determined using a food record and analyzed using Food Processor SQL software.

Results: Short-term FI (p= 0.05) and total EI (p= 0.01) were lower after 100% OJ compared with OD, but did not differ from the water control. Caloric compensation (mean ± SEM), a measure of the efficacy of caloric treatments to suppress FI compared with a non-caloric treatment, was 84.0% ± 38.0 after 100% OJ and-24.7% ± 40.1 after OD. Rest-of-day EI of total carbohydrates was lower after 100% OJ compared with OD (p= 0.02). Subjective appetite score iAUC did not differ among treatments (p > 0.05). Subjective pleasantness of the test treatments was higher after 100% OJ compared with OD (p= 0.009) and water (p= 0.0004). Subjective sweetness was higher after OD compared to 100% OJ (p= 0.003). There was no significant association between subjective sweetness or pleasantness and FI (p > 0.05).

Conclusions: Consumption of 100% OJ suppressed short-term FI resulted in lower total daily EI compared to OD, and similar total daily EI compared to water in normal weight adults. Replacing sugar-sweetened beverages, on a volume basis, for 100% orange juice may lead to lower short-term and total daily EI.
