Found abundantly in blueberries, pterostilbene is a potent antioxidant compound for which studies are yielding mounting evidence relating to its potential role in cardiometabolics. Daniel Riche, from the University of Mississippi (Mississippi, USA), and colleagues enrolled 60 men and women, average age 54 years, who had elevated cholesterol levels. The mean average systolic blood pressure was 127.4 mmHg, and diastolic blood pressure 79.3 mmHg, at the study’s start. Participants either received daily doses of pterostilbene (250 mg), pterostilbene (100 mg) plus grape extract (200 mg), or placebo, for 8 weeks. Among the subjects who received pterostilbene only, systolic blood pressure dropped by 7.8 mmHg and diastolic blood pressure dropped by 7.3 mmHg.

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
