Fruit intake is associated with a decreased risk of cardiovascular disease (CVD). Apple and pears, due to their flavonoids, fiber and antioxidants content, may be also associated to a reduce CVD risk. Therefore the authors of this meta-analysis compiled observational and clinical trials assessing the effects or apples, pears or their products, on cardiometabolic risk factors and clinical outcomes.
Randomized and controlled trials (n = 7) showed only a reducing effect of apple consumption on BMI, whereas blood lipids, body weight, blood glucose and blood pressure were no effected. However, observational studies (n = 14) showed that apple or pear intake significantly decreased risk of cerebrovascular disease, cardiovascular death, type 2 diabetes mellitus, and all-cause mortality.
Therefore, even if the effects of apple and pear on cardiometabolic risk factors are not clear in clinical trials, observational studies substantiate their preventive effects on CVD.
