The research has focused on two types of pears: Bartlett and Starkrimson pears. The Bartlett pear is sometimes known as the Williams' bon chrétien pear. It has a classic bell-shape, and it has an aromatic, strongly ‘pear’ flavor. The pear is commonly used for canning. Starkrimson pears are red colored (brilliant crimson); and they have a milder, sweeter taste.
Through various studies the peel, pulp and juice of these varieties of pears were found to help with the management of type 2 diabetes; to help to reduce hypertension; and deal with the effects of the bacterium Helicobacter pylori, which is associated with intestinal ulcers.
The reason that pears confer these benefits is thought to be due to naturally occurring phenolic compounds that are found within the fruit. More of these beneficial compounds are found in the skin than in the fruit. Comparing the two types of pears, the Bartlett variety had higher total phenolics.
The role of fruit phenolic compounds in protecting health is through their actions in role in mitigating various metabolic and oxidative stressors. Phenolics are thought to play a role in controlling blood glucose levels, with aids diabetes management. The pear pulp may also contain an inhibitor that helps control blood pressure. In terms of ulcers, fermented pear juice has some inhibitory properties against the growth of the ulcer associated H. pylori bacterium.
In addition, pears have other health benefits including fiber content, amino acids, and vitamin C.
