Is pear really "cold"? Shouldn't I eat pears?


It is also the season when the annual autumn pear is hot, and the sweet and crisp pears are particularly popular in supermarkets and markets. However, there are two very different statements about pears in the market.

One statement:

Pear is a good thing! Can moisturize the lungs and diuretic, can dry and laxative! In autumn and winter, dry days are dry and pears are a must-eat fruit!

Statement 2:

Pear can not eat casually! Pears are cold and cold, and hurt the spleen and stomach!

"Compendium of Materia Medica" records: "Pears, Li also. Their sexuality is also fluent." Downstream, fluent, the elderly and women can not eat, pregnant women can not eat!

Is pear really "cold"? Who can't eat?
Here we do not talk about traditional health, directly speaking the scientific truth.
For those who are not interested in scientific reason, please pay attention to the brown subtitle and conclusion.

Eat pear, why
Let you feel "running and laxative"?

Many people feel that pears are good for laxation. Some people with weaker gastrointestinal tract, those who eat cold in the daily life, those who are prone to soft diarrhea on a daily basis, it is especially easy to diarrhea when eating more pears.

After eating the food, it has not been fully digested, and it has been pulled out. It also loses a lot of water and minerals, which is of course not conducive to the absorption and utilization of nutrients. Probably, this is the main reason for the traditional belief that pears are "lower" and "cold".

However, what is the factor that makes pears of this nature?
According to scientific thinking, what is the role of a food is closely related to its composition and structure.



Pears are rich in dietary fiber, and a medium-sized pear can provide 6 grams of dietary fiber, which is a very good data. Many fruits are rich in pectin, a soluble dietary fiber that stimulates the intestinal tract less. However, the insoluble cellulose content in pears is higher. The pear contains "stone cells", which is the one that makes the pears taste small and has a "slag" taste.

Soluble dietary fiber can help the discharge of cholesterol and heavy metals, help maintain the moisture of the stool, promote the fermentation of the large intestine, but it has less stimulating effect on intestinal movement.

Insoluble fibers, especially insoluble substances with relatively large particle sizes, such as small seeds and granules, have a strong ability to promote intestinal movement. The insoluble small particles in the pear should have a good effect in this respect.

However, this is not the only reason why pears promote bowel movements, because the sweet ingredients in pears are also important "pushing hands" for the movement of the large intestine.

The pear tastes sweet, not only because of its high percentage of fructose, but also about 4.5% fructose, and because it is rich in sorbitol.
The sweetness of fructose is 1.2 to 1.5 times that of white sugar (sucrose), and the sweetness is enhanced when the temperature is lowered. The sweetness of sorbitol is almost the same as that of white sugar. However, the sweetness of these two ingredients is different from that of white sugar, which is especially refreshing and pleasant.

Compared with glucose, fructose has a smaller absorption pathway in the intestine, and the absorption and utilization of sugar alcohol is lower, and their absorption rate is much slower than glucose. Unabsorbed fructose and sugar alcohol enter the large intestine via the small intestine. Because both of these ingredients have super strong hydrophilic properties, they can "bound" a large number of water molecules and increase the osmotic pressure of the intestinal contents, stimulating intestinal movement, thereby causing diarrhea.

In short, pears can effectively promote intestinal movement, which is based on scientific basis and composition. Although the pear is sweet and crisp, if you are a person who is prone to diarrhea, it is better to eat less.

However, the so-called all things have advantages and disadvantages, and they have advantages and disadvantages. This characteristic of pears is a huge advantage for those who have dry throat and constipation.



Because both fructose and sorbitol have super-good hydrophilic properties, they carry many water molecules all the way through the digestive tract. It is like a movie star walking on the road will bring a lot of fans around. In this way, all the way from the scorpion to the intestine can increase moisture.

At the same time, because the pear can promote the intestinal movement, the residence time of the food residue and the intestinal fermentation in the large intestine is shortened, and the moisture is not absorbed and dried too lowly, and the dry and hard problem of the stool can be alleviated.

Now everyone understands that the so-called "cold" and "moisturizing" characteristics of pears are actually a kind of experience summary when the ancients did not understand the scientific principles. In most cases, the traditional saying and the scientific truth are not contradictory, just two ways of expression.

What are the health benefits of pears?

In addition to these laxative effects, what are the health benefits of pears? Is pear a fruit of high health value? Here, according to the results of the current research, one item is shared with you.

▍ Nutrients: Not particularly prominent.

Like most fruits, pears are a good source of vitamins C and potassium. A medium sized pear can provide 180 mg of potassium. However, the vitamin C content of pears is not very high, only 7 mg / 100 grams on average, not as good as daily vegetables such as radish cabbage and potatoes.

▍ Phytochemicals: rich in variety and long shelf life.

Pear also contains polyphenolic antioxidants such as flavonoids and lignans.

At present, the storage technology of pears has been very advanced. Experiments have shown that the pear's antioxidant properties can be maintained for up to eight months under good storage conditions.



有利 Helps prevent cardiovascular and cerebrovascular diseases.

Epidemiological studies have found that eating fruits and vegetables can reduce the risk of stroke. Analysis of the types of fruits found that people who regularly eat pears and eat apples have a lower risk of stroke. Epidemiological studies have found that eating flavonoid-rich foods such as pears and apples is beneficial to reduce cardiovascular mortality in postmenopausal women.

有利 Helps prevent type 2 diabetes.

The pear tastes so sweet, will it be easy to get diabetes when you eat it?

If the daily consumption of fruits including pears is within the range of 200-350g of normal recommended amount, don't worry. Because many epidemiological studies have found that healthy adults often consume pears, blueberries, and apples, they can slightly reduce the risk of developing type 2 diabetes.

At the same time, pear is a fruit with a low glycemic index, with a GI value of only 36, the same as apple. People with diabetes can eat pears in small amounts.

▍ Help prevent lung cancer.

EPIC (The European Prospective Investigation into Cancer and Nutrition), a large European nutrition epidemiological study, found that eating pears and apples can reduce the risk of lung cancer.

The American National Institutes of Health's AARP (The American Association of Retired Persons) diet and health study also found that although there is no correlation between total fruit and vegetable intake and total cancer incidence, it is appropriate to eat more Rosaceae fruits. (such as pears, apples, peaches, nectarines, plums and strawberries) is good for preventing lung cancer.

▍ May be beneficial for weight loss.

A foreign clinical study evaluated the effect of adding fruit on the weight of overweight and obese women.
The researchers randomly selected women with a body mass index greater than 25 kg / m2, adding 3 apples, 3 pears or 3 oatmeal cookies to the regular diet, and did not deliberately control calories for 10 weeks. The results showed that the pear and apple groups lost weight, while the oatmeal group did not change in body weight.

The researchers believe that this is due to the lower energy density of pears and apples (less than the same 100 grams of food weight, which contains less heat), so use them as snacks to "charge" instead of other high energy density Food (such as cookies, biscuits, cakes, chips, etc.) can unwittingly reduce calorie intake, and in the long run it has the effect of reducing weight.



▍ Other health benefits...

An animal study using rats as a subject, orally feeding highly polymerized proanthocyanidins extracted from pears, showed high levels of anti-ulcer ability. Other zoological studies have also shown that pears have the effect of regulating alcohol metabolism and lowering blood lipids.

Seeing the benefits of pears so much, are you all tempted? So, is it really like the folks circulated that "the eclipse of the eclipse is not much"?

The answer is of course no.

The Chinese Dietary Guidelines (2016) recommend daily intake of 200-350g of fruit, which is about half a catty. No matter how good the fruit is, there is a limit, and the pear is the same. Studies have shown that excessive fruit is a risk of diabetes.

Who is not suitable for eating pears?

To sum up, eating pears in moderation is good for preventing cardiovascular and cerebrovascular diseases, lung cancer, obesity and constipation. However, not everyone is suitable for pears.

- People with weak digestion, gastroenteritis, diarrhea, and fructose intolerance are not suitable for eating pears.

——Some women are prone to diarrhea during menstruation. At this time, they should eat less or not eat pears, so as not to aggravate the feeling of diarrhea and abdominal discomfort.

- Although pears have a low glycemic index, diabetics still have to control their consumption. Use pear/apple to replace other snacks between meals, or slightly reduce two staples during dinner, and use pear/apple as post-meal food. It is ok, about 100 grams each time.



If menstruating women, pregnant women and children are healthy and have good digestive function, there is no easy diarrhea and gastrointestinal discomfort. After eating pears, they feel happy. It is not necessary to use pears as taboo foods because of "coldness".
