This randomized, open-label, placebo-controlled and crossover study examined the effects of fresh pear consumption (2 pears per day for 12 weeks) in middle-aged/older adults with metabolic syndrome.
The effects of pear was compared to a calorie-matched control drink. Both supplementation periods were separated by a 4-week washout.
After 12 weeks, a trend to decreased in systolic blood pressure (p = 0.07) and a significant decreased in pulse pressure (p < 0.05) has been noted after the pear supplementation. Moreover, leptin concentrations were lower in the pear group than in controls (p < 0.05). In addition, waist circumference was lower after pear supplementation than after the control drink (p < 0.05). Similarly, waist-to-hip ratio was significant lower in the pear group in comparison to control at 6 and 12 weeks (p < 0.05 for both).
Therefore, this study suggest that consumption of 2 pears per day can improve the cardiometabolic health and reduce some anthropometric measures in subjects with metabolic syndrome.
