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.”

59. A Weighty Issue
Obesity and overweight are defined by Body Mass Index (BMI), the measure of body fat defined as body weight divided by the square of your height. Calculate your BMI by using the interactive U.S. National Heart, Lung, and Blood Institute's Body Mass Index calculator, at http://www.nhlbi.nih.gov/health (look under "Health Assessment Tools," and select "Body Mass Index (BMI) Calculator") [provides both Metric and US measurements]. A BMI over 25 kg/m2 is defined as overweight, and a BMI of over 30 kg/m2 as obese.
Overweight and obesity can be life threatening, in that excess weight can result in:
• Cardiovascular disease
• Type 2 diabetes
• Cancer of the breast, colon, prostrate, endometrium, kidney and gallbladder
