Pear: composition, calories, benefits and harms
Pears, along with apples, are affordable and versatile fruits. At the same time, many prefer pears, unable to resist their juicy honey pulp, sweet fruity aroma.
Compound
The pear is characterized by the richness of its chemical composition, which makes it one of the most beneficial fruits for the human body. It contains vitamins A, C, PP, P, K and B vitamins. The mineral composition is represented by such micro and macro elements as zinc, magnesium, manganese, iron, phosphorus, copper, iodine. Most of these elements are dissolved in water, which occupies more than 90% of the volume of the pear. It is correct to call water structured, in its properties it is close to the one that washes the internal organs of a person.
In addition, the fruit contains dietary fiber and pectins, tannins. The sweet taste of fruits is due to sugars, the content of which depends on the characteristics of the pear variety, its place of growth and the degree of maturity. Interestingly, sugars are mostly represented not by glucose, but by fructose. This is important in terms of the fact that fructose does not need to be produced by insulin in order to be absorbed.
The fruits also contain biologically active flavonoids, in particular, quercetin, known for its antioxidant effect.Essential oils in the composition provide a pleasant aroma of fruits, help strengthen immunity and improve mood.
The nutritional value
As already mentioned, the calorie content of a fresh pear is 42 kcal, 1 pear, we must not forget about this, contains more calories, since the mass of the fruit exceeds the indicated 100 g. BJU looks like 10.9 / 0.4 / 0.1 g. usually slightly lower than the same indicators of varietal pears due to the lower sugar content.
The main part of the composition is carbohydrates. There are about 10.9 g of them per 100 g of fresh fruits. In different varieties of fruits, their number may vary slightly. In some, it reaches 15.9 g. Of these, a third is sugar (mainly represented by fructose) and one part is dietary fiber.
Calorie content and glycemic index
Fresh pears can be considered dietary fruits. There are just over 40 calories (kcal) per 100 grams of pear with skin. Few people weigh food before eating, so it's always good to know how many calories are in one medium-sized piece.
On average, the mass of a pear is 130-140 g, so its calorie content reaches 47-57 kcal. Larger fruits can have calorie values up to 75 kcal. The glycemic index of fruits is low - 33 units, which makes it possible to consume them in type 2 diabetes and obesity.
To save fruits for the future allows turning them into dried fruits. Dried pears, if you follow the drying technology, are not inferior in their usefulness to fresh counterparts. However, during the drying process, they lose water, so the concentration of sugars increases, and with it the calorie content. The energy value of 100 g of dried fruits is about 250 kcal.
But if you bake fresh pears, then their calorie content remains almost unchanged and is 46-50 kcal per 100 g. At the same time, dietary fibers become softer, so people with digestive problems prefer such fruits (if coarse fiber causes abdominal pain).
Baking with sugar, honey and nuts significantly increases the calorie content of the dish. In addition, some people like to bake pears with spices. The latter by themselves are unable to significantly increase the energy value of the dessert, but they can stimulate the appetite.
The calorie content of freshly squeezed pear juice is the same as in fresh fruits. True, it contains much less fiber. These figures are valid for natural fresh. Store analogues should be stored for a long time, therefore, at best, they contain preservatives and sugars, which increases their calorie content.
High calorie jam and candied pears. But it is worth noting that with proper heat treatment, they retain almost all the useful elements that are fresh. The energy value of jam is on average 273 kcal / 100 g, candied fruits - 343 kcal for the same volume.
Pears, like apples, can be yellow, red or green. However, unlike them, it always has approximately the same calorie content, equal to 42-45 kcal / 100 g. In other words, when the balance of sugar and organic acids changes, the nutritional value of the fruit remains unchanged. For example, the more sour Conference krusha has the same calorie content as the sweet Autumn one.
The only exception is the ground pear, better known as Jerusalem artichoke. 100 g of the latter contains 73 kcal.
Another important point: the most useful pear is seasonal.Moreover, for each region, the one that grows in these parts is of the greatest value.
What is useful?
Pears contain many vitamins and minerals, which has a positive effect on the body's immune forces when consumed. Regular eating of pears can strengthen the immune system, which is beneficial for human health - the body's resistance to viral and colds, negative environmental factors increases.
The presence of iron, potassium and magnesium, PP vitamins and biologically active flavonoids makes the benefits of pears for the heart and blood vessels obvious. On the heart muscle, the fruit fails to strengthen the effect, improves conductivity.
Other components, including vitamin PP, increase vascular elasticity, capillary permeability. As a result, blood circulation, the state of blood vessels improves, and the level of “bad” cholesterol decreases. Cells and tissues in those who love pears get enough oxygen, since the fruit contains iron. This helps maintain an optimal level of hemoglobin in the blood.
B vitamins are involved in the process of hematopoiesis, contributing to an increase in the content of red blood cells. With their help, as well as under the influence of vitamin K in the body, it is also possible to regulate blood viscosity. Magnesium demonstrates an anticonvulsant effect, helps prevent and relieve muscle hypertonicity.
The fruit increases the resistance of the nervous system to stress and depressive moods, this is largely due to the high content of B vitamins in the composition, which improve the transmission of nerve impulses, strengthen nerves, and help fight insomnia. Delicate pulp and fruity, slightly sweet aroma will undoubtedly cheer you up. In other words, a pear can be considered an antidepressant.
For men, the high content of vitamin B, zinc, as well as the antibacterial effect of pears have a beneficial effect on the reproductive system and hormonal levels. Under the influence of vitamin B and zinc, testosterone is produced.
The low calorie content of the pear and the high amount of fiber makes it possible to consume the pear for weight loss. It contains organic acids that improve digestion and speed it up. Fiber stimulates intestinal motility and helps to remove waste and toxins from it. This, in turn, allows you to accelerate metabolic and lipid processes. But it is a metabolic disorder that becomes one of the main causes of a number of diseases and problems with being overweight.
Dietary fiber helps to gently cope with the problem of constipation, that is, fresh fruits have a laxative effect. A decoction based on leaves and fruits, on the contrary, helps to cope with diarrhea, has strengthening properties. Firm, slightly astringent pears are also characterized by a fixing property, so they are not recommended for people suffering from constipation. Fruit seeds are a natural antihelminthic and antiparasitic agent.
Thanks to the antioxidants in the composition of the pear, they also remove toxins, slow down the aging process of cells, and have some antitumor effect. In terms of their antibacterial properties, the fruits can be compared with broad-spectrum antibiotics, and also demonstrate a slight antipyretic effect. Unlike a number of fruits containing organic acids, pears do not cause a sharp increase in hydrochloric acid in the stomach, and therefore can be consumed even with ulcers and gastritis. In addition, their intake is indicated in the first stages of cholecystitis as a natural product that alleviates the patient's condition.The pear contains a lot of iodine, which makes the fruit useful for the thyroid gland. It is responsible for the production of hormones, which, as you know, regulate all vital processes in the body.
Fruits have a diuretic effect and help remove excess moisture from the body. If we recall the antibacterial effect of pears, then we can say that these fruits can be used as preventive products against diseases of the urinary and reproductive systems. The pear contains vitamins such as B1, -2, -5, -6, -9. The latter is known as folic acid. It is vital at the stage of pregnancy, as it is involved in the formation of the nervous system of the fetus, the brain and spinal cord. In addition, the immunostimulating properties of a pear, its ability to improve digestion and increase hemoglobin are also very useful for a woman in a position.
Since the sweetness of the pear is due to its fructose content, it does not adversely affect the pancreas. This means that after consuming the fetus, insulin surges are excluded. In addition, a large amount of fiber prevents the rapid absorption of sugar into the blood. This allows you to use pears for type 2 diabetes.
True, it is better to consult a doctor first. Like apples, pears rarely cause allergies because they lack salicylates and benzoates.
Contraindications
Pears with hard skin and pulp contain a large amount of fiber, therefore, with a weak intestine, they can cause pain in the abdomen, a feeling of heaviness. During the period of exacerbation of gastritis, ulcers, pancreatitis, pears are prohibited.
These fruits should not be served as a dessert immediately after the main meal. It is not recommended to drink them with water.All this is fraught with the occurrence of putrefactive processes in the intestines, the appearance of a feeling of bloating, and indigestion. It is better to allocate a separate meal for eating pears.
Unripe pears, as well as overripe, damaged, with traces of rot, will not benefit a person, but only harm. Their composition is unknown, which means that the truth about the benefits of imported pears that appear on the counter in the off season is debatable. You should also refuse to buy if the fruits have a beautiful glossy surface. It is obtained by chemical treatment of pears, and the applied composition is not completely washed off even in hot water.
Features of use
Pears should be consumed with the peel, since it contains the main amount of ascorbic acid and fiber. The maximum dosage for an adult is no more than 2 fruits per day. Do not eat pears, drink them with water, especially cold.
When losing weight
Those who want to lose weight, normalize metabolism and cleanse the intestines can regularly include pears in their diet. To do this, it is better to single out a separate meal and eat pears along with the skin, and, if possible, with the bones. In the absence of contraindications, it is allowed to consume 1-2 fruits daily, choosing varieties with a small amount of sugar (they taste more solid and sour).
For more effective and efficient weight loss, you can resort to fasting days on pears. For a week on such a diet, as the reviews say, you can “throw off” up to 3-4 kg without feeling hungry and without exposing the body to an acute vitamin and mineral deficiency.
There are many diets, but the following is the most popular.The essence of this food system is that before lunch you can consume almost any dish (within the framework of proper nutrition, of course). Nutritionists in this case recommend taking a breakfast of slow carbohydrates (porridge) with a small amount of protein (cottage cheese, eggs).
A snack can be “give away” to fiber and fatty acids (vegetable salad seasoned with olive oil, nuts, seeds, a handful of dried fruits). At lunch, you need to "lean" on carbohydrates (40% of the serving). The rest should be protein and fiber (a side dish of buckwheat, rice, durum spaghetti with boiled breast or steamed fish and a large portion of vegetable salad is the best).
After dinner, only raw pears are eaten. The first portion should be eaten no earlier than 2-3 hours after the meal. You can diversify the pear diet by replacing one of its methods with fresh pear juice, pear salad and low-fat yogurt, and baked fruits. It is important to monitor the water balance. As a drink, in addition to the specified fresh juice, mineral water, herbal teas, fat-free kefir are suitable.
As you can see, this dietary option is not associated with a strong reduction in daily calorie intake. For more impressive results, you can use a two-week diet, during which you can get rid of 7-9 extra pounds. Breakfasts here are represented by a small piece of whole grain bread or a serving of oatmeal on the water with a pear. Lunch - buckwheat, wild rice with boiled breast. Dinner - vegetables and herbs. In between meals, eat 1-2 pears.
When going on a diet, it is important to remember that no matter how desirable the result is, extreme weight loss in a short time is stressful for the body.And the kilograms shed so rapidly usually return, “bringing” new ones with them.
With pancreatitis
The menu for pancreatitis depends on the characteristics and stage of the disease. A particularly strict diet has to be followed during an exacerbation of the disease and in the first days of recovery after it. During an exacerbation of pancreatitis, the consumption of pears is prohibited. On the 7th-8th day during the remission period, it is allowed to introduce some fruits and vegetables into the patient's diet.
Preference is given to non-sour apples. And although they contain more organic acids, they are better absorbed than pears. The latter contain stony cells, in which chemical elements (cutin, calcium carbonate) can be concentrated that are not digested by the stomach of a sick person. Their presence can be guessed from the dense inclusions that are present in the pulp of pears.
In chronic pancreatitis, it is allowed to eat 1 fruit once a week. In this case, it is better to divide it into 3-4 parts and distribute it over several days. That is, the best option is a quarter of a fresh pear every 1-2 days. It is better, of course, to bake the fruits, because this way it is possible to soften the above stony cells.
You can also cook compotes and decoctions from pears. In this case, the notorious stony compounds will settle at the bottom of the dishes. They should not be drunk, and before use it is advisable to filter the compote or decoction.
During pregnancy
Pears during pregnancy will provide the woman's body with folic acid, strengthen the immune system and the cardiovascular system. In addition, they will help to cope with constipation, which often occurs in the first and third trimester of the "interesting position".
During pregnancy, it is allowed to eat 1-2 fruits every other day. Do not eat them before breakfast and immediately after the main meal.A good option is to eat fruit for an afternoon snack or as a second breakfast. But it is better to refuse eating these fruits at night because of their diuretic effect.
In the last trimester of pregnancy, the growing uterus crowds many internal organs, including the intestines. Stimulation of the latter can provoke uterine contractions, which is fraught with premature birth. In this regard, in the last weeks of gestation it is recommended to peel pears, reduce the frequency of their consumption to 1-2 times a week. You can replace the fruits with freshly squeezed juice.
