The pear is a sweet fruit that is said to be related to the apple. Its size is about that of an apple with several seeds in the core, like an apple. Unlike apples though, most pear varieties have paper-thin skins which are not easy to peel. The skins vary in color¾yellow, green, brown, red, or a combination of any of these colors.
The light color flesh of pears is juicy, sweet and usually mild. Its texture is soft and buttery and some varieties have grainy flesh. We usually think of pear as bell-shaped, but some varieties are shaped almost like a rounded apple.
Among all the variety of pears, the Chinese pear is known to have the most medicinal values. But nonetheless, the other varieties are also healthful in their own right.
Health Benefits of Pear
Pears are often recommended as a hypo-allergenic fruit that is high in fiber but less likely to produce adverse reactions. Pear juice is safe to be introduced to infants as they are mild, yet healthful.
Blood pressure: Pears have anti-oxidant and anti-carcinogen glutathione which help prevent high blood pressure and stroke.
Cancer prevention: The high vitamin C and copper content act as good anti-oxidants that protect cells from damages by free radicals.
Cholesterol: The high content of pectin in pears make it very useful in helping to lower cholesterol levels.
Colon health: When not juicing, eat the pear whole for its precious fiber that are highly beneficial for your colon health.
Constipation: The pectin in pears is diuretic and have a mild laxative effect. Drinking pear juice regularly helps regulate bowel movements.
Energy: You can get quick and natural source of energy from pear juice, due largely to its high amounts of fructose and glucose.
Fever: The cooling effect in pear is excellent in relieving fever. Best way to bring a fever down quickly is by drinking a big glass of pear juice.
Immune booster: The anti-oxidant nutrients in pears are critical in building up your immune system. Drink pear juice when you feel a cold coming.
Inflammation: Pear juice has an anti-inflammatory effect and helps relieve sufferers of much pain in various inflammatory conditions.
Osteoporosis: Pears contain high level of boron. Boron helps the body to retain calcium, thus prevents or retards osteoporosis.
Pregnancy: The high content of folate (folic acid) prevents neural tube defects in infants.
Shortness of breath: The summer heat may cause children to have shortness of breath with excessive phlegm. Drink pear juice during this period to help clear the phlegm.
Throat problem: The pears are in season during the summer for a reason. Drinking pear juice every morning and night helps to cool your body down during this time. It nourishes the throat and helps prevent throat problems.
Vocal chord: Boil two Chinese pear juice with some raw honey and drink warm. This is extremely healing for the throat and the vocal cord.
Antioxidant and Anti-Inflammatory Support
While pears are not an unusual source of conventional antioxidant or anti-inflammatory nutrients (for example, vitamin E or omega-3 fatty acids), the phytonutrient category is where this fruit excels. For example, in the Baltimore Longitudinal Study of Aging (1,638 participants, average age range 62-69 years), the combination of apples/pears ranked as the second highest source of flavonols among all fruits and vegetables – partly due to the epicatechin richness of pears. Average flavonol intake in the study was about 14 milligrams per day, and one pear can provide about half of this amount all by itself. The list of phytonutrients found in pears has been of special interest to researchers, and the list below summarizes their findings about key phytonutrients provided by this fruit.
- chlorogenic acid
- gentisic acid
- syringic acid
- vanillic acid
- coumaric acid
- ferulic acid
- 5-caffeoylquinic acid
Flavanols, also known as Flavan-3-ols
Anthocyanins (in red-skinned varieties, including Red Anjou, Red Bartlett, Comice, Seckel, and Starkrimson)
Virtually all of these phytonutrients have been shown to provide us with antioxidant as well as anti-inflammatory benefits. As a result, intake of pears has now been associated with decreased risk of several common chronic diseases that begin with chronic inflammation and excessive oxidative stress. These diseases include heart disease and type 2 diabetes.
Decreased Risk of Type 2 Diabetes and Heart Disease
As a very good source of dietary fiber, pears might logically be expected to help protect us from development of type 2 diabetes (or DM2, which stands for “diabetes mellitus type 2) as well heart disease. Adequate intake of dietary fiber is a long-established factor in reducing our risk of both diseases, and in the case of pears, this benefit may be even more pronounced due to the helpful combination of both soluble and insoluble fiber in this fruit. In addition to their fiber content, however, pears have other ways of helping to protect us against these diseases. In the case of DM2, scientists now know that pear flavonols (including isorhamnetin, quercetin, and kaempferol), flavan-3-ols (especially epicatechin), and the anthocyanins (found in red-skinned varieties including Red Anjou, Red Bartlett, Comice, Seckel, and Starkrimson) all help improve insulin sensitivity. (More and more research attention is being given to mechanisms of action in this area, including regulation of the enzyme NADPH oxidase.) In the case of heart disease, recent research has shown that pear fibers are able to bind together with bile acids in the intestine, lowering the pool of bile acids and decreasing the synthesis of cholesterol. In addition, the phytonutrients in pear may play a special role in these fiber-bile acid interactions. The ability of pear fibers (and other fruit fibers) to bind bile acids has actually been compared to the cholesterol-lowering drug cholestyramine, with pears showing about 5% of the ability of the drug to accomplish this result. (Among commonly eaten fruits, only bananas and pineapples showed more bile acid-binding ability at 9% and 6%, respectively.)
Reduced Cancer Risk
The health benefits of pear fiber also extend into the area of cancer risk. Fiber from pear can bind together not only with bile acids as a whole, but also with a special group of bile acids called secondary bile acids. Excessive amounts of secondary bile acids in the intestine can increase our risk of colorectal cancer (as well as other intestinal problems). By binding together with secondary bile acids, pear fibers can help decrease their concentration in the intestine and lower our risk of cancer development. In the case of stomach cancer (gastric cancer), intake of pears has also been shown to lower cancer risk. Here the key focus has not been on pear fiber, however, but on pear phytonutrients, especially cinnamic acids (including coumaric acid, ferulic acid, and 5-caffeoylquinic acid). In a recent study from Mexico City, it took approximately 2 total fruit servings per day and 4 daily vegetable servings to accomplish a decrease in gastric cancer risk. Pears and mangos were among the key foods determined to provide cinnamic acids in the study.
Esophageal cancer (specifically, esophageal squamous cell carcinoma, or ESCC) is a third cancer type for which pear intake helps lower risk. In a very large-scale study conducted by the National Institutes of Health and the American Association of Retired Persons (involving 490,802 participants), pears were found to be a key food associated with reduced risk of ESCC. Interestingly, numerous foods belonging the rose (Rosaceae) family were also found to lower risk of ESCC, including apples, plums, and strawberries.
Other Health Benefits
It’s become fairly common to hear both laypersons and healthcare practitioners talking about pear as one of the more easily digested fruits. In fact, many practitioners recommend that pear be one of the first fruits considered when it comes time to introducing an infant to his or her first pureed fruits. Even though we have been unable to find large-scale human studies to support these digestibility claims, we don’t question the fact that easier digestion has been experienced by many individuals in the context of pears versus other fruits. One factor that may come into play here is the low acid nature of pears, especially in comparison to widely enjoyed citrus fruits like lemons, grapefruits, and oranges.
It’s also become fairly common to hear pears being described as a “hypoallergenic” (low allergy) food. Healthcare practitioners often allow clients to continue eating pears when following a low-allergy diet plan, and many individuals report having fewer allergy-related symptoms when consuming pears versus other fruits. Of course, no fruits are classified as major allergens according to the U.S. Centers for Disease Control and their rules for identification of allergenic foods on product labels. In addition, we have been unable to find large-scale research studies to support any low-allergy claims for pears. Still, we do not question the fact that many people seem to do much better when consuming pears versus other fruits in terms of allergic response.
It’s very possible that these two experiences – better digestibility and decreased allergic response – are related, and that future research will help us understand why pears may provide us with special health benefits in these areas.
