Benefits of Adding Pear in Your Daily Diet
Helps in Weight Loss
Pear, because of its low caloric value, is good to include in your diet aimed at shedding weight. It keeps you fuller for a longer because it has extremely high fiber content, especially at the centre, which gives excellent results in combating constipation and digestive issues as well. Just one medium pear provides 6 grams of fiber, about 24% of the daily need for a woman under 50, as per The Food and Nutrition Board of the National Institute of Medicine (2001) reports.
Combats Cardiovascular Diseases
Pear is loaded with minerals like sodium and potassium. These are vital for improving blood circulation and strengthening the heart muscles. The fiber brings downs blood sugar and cholesterol levels, keeping the heart in a good working condition.
Reduced Risk of Colitis
This condition, marked by intestinal inflammation is once again relieved by the high fiber quantity found in pears. “The colon trouble can be cured in one week by taking half a kilogram of fresh pears before all three main meals. However, before eating the fruit, the skin should be peeled off,” says Dr. Sood.
Antioxidant and
Anti-Inflammatory Support of Pears
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.
Hydroxybenzoic acids
- chlorogenic
acid
- gentisic
acid
- syringic
acid
- vanillic
acid
Hydroxycinnamic acids
- coumaric
acid
- ferulic
acid
- 5-caffeoylquinic
acid
Hydroxyquinones
- arbutin
Flavanols, also known as Flavan-3-ols
- catechin
- epicatechin
Flavonols
- isorhamnetin
- quercetin
- kaempferol
Anthocyanins (in red-skinned varieties, including Red Anjou, Red
Bartlett, Comice, Seckel, and Starkrimson)
Carotenoids
- beta-carotene
- lutein
- zeaxanthin
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.
Pears May Possibly
Decrease 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.)
Pears May Possibly
Reduce 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
of Pears
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.
Detailed
Pears
are a member of the rose family of plants (Rosaceae), which, in addition (of
course) to roses, contains a long list of fruits including apples, apricots,
cherries, chokeberry, crabapples, loquats, peaches, plums, quinces,
raspberries, serviceberries, and strawberries as well as the tree nut, almonds.
The many different varieties of pears commonly found in U.S. groceries all
belong to the same category known as European Pear (Pyrus communis). These
pears typically have a rounded body that tapers into a neck of various lengths.
They are distinct from (but closely related to) the fruit we commonly call "pear apple." Pear apples are completely round with no necks, and while they remind of us of apples in shape, their skins make us think they are pears. Contrary to popular belief, pear apples are not a cross between apples and pears. Pear apples belong to a second category of pear, broadly referred to as Asian pear. Included in this second category are Chinese pear, Japanese pear, and Korean pear (Pyrus pyrifolia) as well as Siberian/Manchurian pear (Pyrus ussuriensis). When these categories are combined, they account for more than 3,000 varieties of pears that people enjoy worldwide.
Pears are found in a variety of colors, including many different shades of green, red, yellow/gold, and brown. Many varieties fail to change color as they ripen, making it more difficult to determine ripeness. (For more about selection of pears, please see our How to Select and Store section.)
The
list below describes some of the more commonly enjoyed varieties of pears:
- Bartlett: best
known of the pear varieties in the U.S., and most often the variety found
in cans. Bartletts are yellow/green and speckled, and sometimes
called Williams pears
- Bosc: cinnamon
brown-skinned pears with long tapered necks with a honey-like but complex
flavor
- Comice: round,
short pears with either green and red coloring, or sometimes almost
completely red with especially soft and juicy flesh
- Concorde: tall,
skinny, and golden/green pears with flesh that is firmer and more dense
than many other varieties
- Forelle: red/green
and speckled like a trout, and thus the name, meaning "trout" in
German. A small-sized pear that yellows as it ripens.
- Green Anjou: a
widely available, compact, and short-necked pear. It doesn't change color
much while ripening, so you'll need to use the stem test described in our
How to Select and Store section.
- Red Anjou: very
much like its green counterpart, except a rich reddish maroon in color and
higher in anthocyanins (which is the main reason for its rich red color)
- Red Bartlett: very
much like its yellow/green counterpart, except with an all-round bright
red skin, they sometimes feature light vertical striping, and like Red
Anjou, they are rich in anthocyanins
- Seckel: smallest
of the commonly eaten pears, usually yellow/green or olive green in color,
and mixed with broad patches of red
- Starkrimson: bright
crimson red color, more narrow-necked that Red Anjou, but equally rich in
anthocyanins and especially gorgeous in a salad
Focus on History
There
is some debate about the exact origins of the European pear, but many experts
believe that European pears (Pyrus communis) and Asian pears (both Pyrus
pyrifolia and Pyrus ussuriensis) evolved separately and during the
same approximate time in history (roughly 1000 BC). Certain species of pear are
also native to parts of Africa.
Beginning in the 1500's, Eurpoean colonists began to bring pears to North America, where they apparently were not native or enjoyed before that time. While pears were cultivated there during those years, the colonists continued to import most of the pears they consumed from Europe, and especially from France. Today, pears grown in Europe have become a very small part of the U.S. diet. While the U.S. continues to import over 75,000 metric tons of pears each year, the vast majority now come from Argentina, Chile, China, South Korea and New Zealand.
On a worldwide basis, China has become the world's largest grower of pears. Out of 21 million tons produced worldwide, China now produces about 15.5 million tons, or nearly three-quarters of the world total. Of the remaining 5.5 million tons, another 2.7 come from Europe, 1.1 from Argentina and Chile, 0.8 from the U.S., and smaller amounts from New Zealand, South Korea, and other countries.
Within the U.S., the state of Washington is by far the largest grower of pears, accounting for about half of all U.S.-produced pears. California and Oregon follow next, with significant commercial production also occurring in New York and Pennsylvania.
How to Select and
Store
Since
pears are very perishable once they are ripe, the pears you find at the market
will generally be unripe and will require a few days of maturing. Look for
pears that are firm, but not too hard. They should have a smooth skin that is free
of bruises or mold. The color of good quality pears may not be uniform as some
may feature russetting where there are brown-speckled patches on the skin; this
is an acceptable characteristic and oftentimes reflects a more intense flavor.
Avoid pears that are punctured or have dark soft spots.
It
is possible, of course, that you may find ripe pears at the market. When trying
to determine whether a pear is ripe, don't start by squeezing the whole fruit.
Instead, we recommend gently pressing only at the top of the pear, near its
stem. If that spot gives in to pressure, the pear is probably optimally ripe
for eating. If the flesh feels extremely soft, almost to the point of being
squishy, the pear is overripe. For food safety reasons, we recommend that overripe
pears only be used in cooked recipes rather than eaten raw.
We encourage the purchase of certified organically grown foods, and pears are no exception. Repeated research studies on organic foods as a group show that your likelihood of exposure to contaminants such as pesticides and heavy metals can be greatly reduced through the purchased of certified organic foods, including pears. In many cases, you may be able to find a local organic grower who sells pears but has not applied for formal organic certification either through the U.S. Department of Agriculture (USDA) or through a state agency. (Examples of states offering state-certified organic foods include California, New York, Oregon, Vermont, and Washington.) However, if you are shopping in a large supermarket, your most reliable source of organically grown pears is very likely to be pears that display the USDA organic logo.
As
with all of the World's Healthiest Foods, we recommend that you purchase
certified organic pears to lower your risk of exposure to unwanted pesticides,
sewage sludge contaminants, and any potential risks associated with irradiation
or genetic engineering. Fortunately, over 250 certified organic farms in the
U.S. now produce over 20,000 tons of organic pears, and so these delicious
fruits are getting easier to find in organic form.
If you will not be consuming the pears immediately once they have ripened, you can place them in the refrigerator where they will remain fresh for a few days. If you want to hasten the ripening process, place them in a paper bag, turning them occasionally, and keep them at room temperature. Storing pears in sealed plastic bags or restricted spaces where they are in too close proximity to each other should be avoided since they will have limited exposure to oxygen, and the ethylene gas that they naturally produce will greatly increase their ripening process, causing them to degrade. Pears should also be stored away from other strong smelling foods, whether on the countertop on in the refrigerator, as they tend to absorb smells.
Individual Concerns
Between
2008-2016, concerns arose in both the U.S. and Canada over contamination with
arsenic of certain brand-name pear juices. While we have never seen official
reports pinpointing the exact source of the contamination, it would not be
uncommon for a food like pear juice - made from pears that may have been
imported from nearly a dozen countries throughout the world - to pick up
unwanted heavy metal residues (like arsenic) from groundwater contamination,
soil contamination, sewage sludge fertilization, or some combination of these
sources. Pear juices found to be contaminated were recalled by the U.S. Food
and Drug Association (FDA) and the Canadian Food Inspection Agency (CFIA), and
the FDA also set a Level of Concern for arsenic in fruit juices (including pear
juice) of 23 parts per million (for long-term, routine consumption of pear
juice). Companies who voluntarily chose to monitor their pear juice production
were then able to use this standard as a guideline. These events are one of the
reasons we encourage selection of organic pear juice (and fresh pears). Organic
food regulations greatly lessen the chance of exposure to heavy metals like
arsenic not only in pear juice and pears but in all other foods as well.
Nutritional Profile
Pears
are a concentrated source of phenolic phytonutrients, including hydroxybenzoic
acids (chlorogenic acid, gentisic acid, syringic acid, and vanillic acid);
hydroxycinnamic acids (coumaric acid, ferulic acid, and 5-caffeoylquinic acid);
hydroxyquinones (arbutin), flavanols (catechin, epicatechin); flavonols (isorhamnetin,
quercetin, kaempferol); anthocyanins (in red-skinned varieties, including Red
Anjou, Red Bartlett, Comice, Seckel, and Starkrimson); and carotenoids
(beta-carotene, lutein, zeaxanthin). Pears are a very good source of dietary
fiber and a good source of copper, vitamin C and vitamin K.
A typical fruit of temperate regions, pears have been one of the world’s oldest cultivated produce, given their versatility and long storage life. It has its origin and domestication at two different regions, China and the Middle East. At present, Oregon and Washington are regarded as highly specialised regions that support pears, with more than 1,600 pear growers.
The Chinese merchants brought this delicious delight to Amritsar’s village Harsa Chhina in around 120-170 AD. The nomenclature can be attributed to Latin words ‘pera’ or ‘pira’, with some variants like the French ‘poire’, German ‘peer’, and Greek ‘acras’ (wild type) and ‘apios’ (cultivated type).
Known as ‘patharnakh’ in Punjab, it has become a commercial fruit crop of the state. In Himachal Pradesh and UP, the fruit is cultivated under the name of ‘gola pear’. India's pear season lasts from late summer to early winter.
