Cloudy apple juice, juice in which the apple pectin and starch are retained, is rich in polyphenols, compounds that have been shown in previous studies to exert a variety of health effects.  Stephan W. Barth, from the Max Rubner Institut (Germany), and colleagues enrolled 68 obese, non-diabetic men, to receive either 750 mL of cloudy apple juice daily, or a control beverage, for four weeks.  The men who consumed the cloudy apple juice displayed 1% reduction in total body fat  (as compared to 0.2% in the control group). Further, the researchers observed that those men with a specific gene polymorphism (IL6-174 G showed a 2% reduction in total body fat after 4 weeks of cloudy apple juice.  The study authors submit that: “The observed diet–gene interaction might be a first indication for the impact of individual genetic background on [cloudy apple juice]-mediated bioactivity on obesity-associated comorbidities.”
