Beneficial Health Effects of Polyphenol-Rich Fruit Juice in Humans

Polyphenols 2022 Speakers - Prof. Elke RichlingProf. Elke Richling, University of Kaiserslautern, Germany, will join Polyphenols Applications 2022 to present recent advances on the "Beneficial Health Effects of Polyphenol-Rich Fruit Juice in Humans".

In vitro and in vivo studies provide evidence that polyphenol-rich fruit juices and their extracts can influence lipid metabolism as well as improve DNA integrity.

To substantiate preliminary findings, Prof. Richling and her team performed a placebo-controlled intervention study with 36 male healthy subjects (age 20–40 years, body mass index 19–25 kg/m2). After one week washout period, the volunteers consumed 750 mL/day of a polyphenol-rich fruit juice (containing chokeberry, cranberry, and pomegranate) or placebo drink for eight weeks. Blood sampling was performed after the washout period as well as after four and eight weeks of intervention and used to analyse biomarkers of the lipid metabolism like blood platelet cyclic adenosine monophosphate phosphodiesterase (cAMP-PDE) activity. In addition, effects on DNA strand breaks and on body weight/composition were monitored.

The results showed a significant inhibition of cAMP-PDE activity (p<0.01) and decrease in DNA strand breaks (p<0.05) during juice consumption. Consuming juice, an increased fat-free mass (p<0.05) was found after four weeks, whereas a significant (p<0.05) elevation in body weight was observed in control group.

Taken together their results indicate health beneficial effects associated with polyphenol-rich fruit juice consumption.

Join us in Polyphenols Applications 2022 to know more about these findings and many more topics.
