citrus fruits are rich sources of several biologically active flavonoids such as hesperidin,naringin,and polymethoxylated flavones.We evaluated the evidence of associations between citrus fruit or hesperidin intake and multiple health outcomes.An umbrella review was conducted for studies performed in humans.Overall,246 articles were initially identified by searching in 4 databases.Twenty-two meta-analyses and systematic reviews with 28 health outcomes met the inclusion criteria.citrus fruit intake had beneficial effects on all-cause mortality(relative risk[RR].0.90;95%confidence interval[95%CI],0.86 to 0.94),cardiovascular diseases(RR,0.78;95%CI,0.66 to 0.92),coronary heart disease(RR,0.91;95%CI,0.86 to 0.96),stroke(RR,0.74;95%CI,0.65 to 0.84),type 2 diabetes mellitus(RR,0.85;95%CI,0.78 to 0.92),and several cancers.Dose-response analyses indicated that each 100-g/d increase in citrus fruit intake could reduce the risks of all-cause mortality by 6%(RR,0.94;95%CI,0.88 to 1.00),stroke by 22%(RR,0.78;95%CI,0.69 to 0.90),and cardia gastric cancer by 40%(RR,0.60;95%CI,0.44 to 0.83).citrus fruit intake also had beneficial effects on the lipid profile and body weight control(weighted mean difference,−1.28;95%CI,−1.82 to−0.74).Grapefruits could reduce the systolic blood pressure(weighted mean difference,−2.43,95%CI,−4.77 to−0.09).Hesperidin supplementation significantly improved inflammation.citrus fruit intake was generally safe and beneficial for multiple health outcomes in humans.However,grapefruit and pomelo juice may affect the bioavailability of various medications,so care should be exercised before increasing the intake of these fruits or their juices.

The effects of eating fresh citrus fruits including two varieties of mandarins,one of sweet oranges,one of grapefruit,two of pomelo,and one of kumquat cultivated in China on endogenous antioxidant enzymes were investigated by in vitro digestion and HepG2 cells.The correlations between enzyme activity and cell uptake of phytochemicals and cellular antioxidant capacities were analyzed.The results showed that most fresh citrus fruits increased the endogenous antioxidant activity.Bairoumiyou,Hongroumiyou,Ponkan,and Jinju after digestion significantly increased the activity of catalase(Pcitrus fruits except Ponkan(Pcitrus fruits had a higher increase than added citrus fruits extracts.The results indicated that edible whole citrus fruits had similar effects as extracts on enzymes.
