Brief summary
Although epidemiological studies have associated the consumption of sugary beverages with adverse health effects, experimental studies have demonstrated that the metabolic response of the human body to fruit juice as compared to artificial beverages is substantially different. Fruit juices do not just provide sugars and related calories, but they are rich sources of bioactive compounds especially of flavonoids. Flavanones constitute a class of flavonoids that are specifically and abundantly found in citrus fruits, with hesperidin being the major compound in orange. From prospective cohort studies, higher intakes of flavanones are associated with a lower incidence of mortality by cardiovascular disease (CVD). This relation is supported by results from a number of animal studies demonstrating a slowdown in atherosclerosis development and vascular protective effects in dietary interventions with flavanones. Randomized, controlled clinical trials to corroborate the suggested vasculo-protective effects of orange juice presumably mediated by the flavanones are scarce and available data do not allow to draw firm conclusions about their efficacy. To fill this gap, the HESPER-HEALTH study conducted in humans will assess the vascular protective effects of 100% orange juice consumption and evaluate the contribution of hesperidin in these effects.
Detailed description
This human dietary intervention study is a double blind, randomized, placebo controlled, cross over trial with 3 arms, carried out on subjects with predisposition to cardiovascular diseases (CVD) based on age and overweight. This study aims to demonstrate the vascular protective effects (with Flow Mediated Dilatation (FMD) as main criteria) of the consumption of a flavanone rich orange juice or of orange flavanones by comparison with a control sugary drink alone. The 42 recruited participants will receive the 3 drinks in a random order. For each subject, the study is divided into 3 identical experimental periods of 45 days (period 1,2,3): including 3 days prior to the beginning of the product intake, during which specific dietary guidelines, samplings and measures will be asked to be performed at home followed by a 6 weeks period of consumption of each of the 3 beverages). A period of 4 to 6 weeks of wash-out is planned between each experimental period. To summarize: Visit 1 (D-14) = inclusion, Visit 2 (D1: baseline) to 3 (D42) = period 1, Visit 3 (D42) to 4 (D70) = wash out 1, Visit 4 (D70) to 5 (D111) = period 2, Visit 5 (D111) to 6 (D139) = wash out 2, Visit 6 (D139) to 7 (D180) = period 3. The wash-out periods (minimum duration: 4 weeks) may be extended until 6 weeks for the convenience of participants. The protocol includes a total of 7 visits to PIC/CIC Inserm 1405 of the Clermont-Fd University Hospital. The total duration of the study will be between 28 and 34 weeks
Interventions
BEHAVIORALBeverage consumption
Volunteers will consume, in random order, daily 330 ml of 1 experimental beverage per period (Orange Juice, Control Beverage, Control Beverage supplemented with hesperidin) for 6 weeks in each period. At the beginning and the end of each period, exploration will be conducted at fasted state and at post-prandial state after the administration of a high-fat high-sugar meal.
