Vital nutrients, vitamin C, antioxidants, and fiber can all be found in pears, and play a proactive role in maintaining a healthy diet and fighting against various cancers (1). Danish women who ate a healthy Nordic diet pattern, which included regular consumption of pears (part of the traditional Nordic diet), had a lower risk of colorectal cancer. (Br J Nutr, 2013). And data from the NIH-AARP (Am J Epidemiology 2007) study found that among common fruits and vegetables, there was a particularly protective effect from the intake of Rosacea fruits, such as pears, on esophageal cancer. (IntJ Cancer, 2007)

In another study, a diet high in fruit and low in meat was found to reduce risk for colorectal adenomas. Of 725 individuals undergoing colonoscopy, 203 had colorectal adenoma(s) versus 522 controls. Compared to those consuming a high fruit and low meat diet, those eating a high vegetable and moderate meat diet had 2.17 times increased odds of developing colorectal adenomas, and those eating a high meat diet had 1.7 times increased odds of having had colorectal adenomas. This study suggests that a diet high in fruit consumption and low in meat consumption may be protective against the development of colorectal adenomas, even when compared with a group that consumes a large amount of vegetables.

Another study that observed 521,457 participants at 23 centers in 10 European countries as part of the European Prospective Investigation into Cancer and Nutrition (EPIC) study found that increasing fruit intake, especially pears and apples, may be protective against lung cancer risk in the overall population and those who smoke! This effect is attributed to nutrient-density of the fruits, vitamin C, fiber, antioxidants, etc., and their wide availabilities. Again, as the consumption of fruit increased, risk for lung cancer decreased in the observed participants. Consume more pears and you’ll be eating more vitamin C, fiber, and antioxidants that that may protect against lung cancer.
