Since the times of the Old Russian kingdom, jam has been considered the most delicious and healthy delicacy. It could only be seen on the tables of rich people, since the main ingredient of jam in those days was not sugar, but honey. Sometimes fruits and berries were cooked in sweet molasses.

Harm with this method of cooking was practically eliminated, and therefore classic jam was an expensive pleasure. It was used in the treatment of many diseases, and for good reason, because this product is a storehouse of the most valuable vitamins and microelements.

It is known that previously it was common not only to make jam from berries and fruits, but also from all kinds of vegetables, herbs and nuts. Naturally, some people still cook this healthy delicacy from radishes, carrots, turnips, pumpkins, and even green tomatoes, but you rarely come across such an unusual dish these days.

To understand the health benefits and harms of this product, you should consider the vitamin composition of several types of jam separately.

The most common types

1. From raspberries

It is traditionally believed that the healthiest jam can be made from raspberries, since it contains special substances - phytoncides. It is thanks to their influence that during any colds, raspberry jam helps no worse than pharmaceutical drugs and antibiotics. The high content of vitamin C, which is a natural antioxidant, allows you to consolidate the effect, acting as an antimicrobial and antipyretic component. The use of this product helps to normalize metabolic processes in the body, prevent the proliferation of cancer cells, and also neutralizes harmful carcinogens.

1. From viburnum

The combination of this healing berry with honey can relieve the first signs of flu, sore throat and any cold. Viburnum contains approximately 1.5 times more vitamin C than citrus fruits! Due to the presence of seeds, this wild berry is rarely boiled, but many years ago such jam was considered the most powerful remedy not only for colds, but also for skin problems, severe bleeding and disorders of the stomach and intestines. Also, such a tasty medicine has a calming effect on the central nervous system, has a mild diuretic effect and normalizes blood pressure.

1. From black currant

Like viburnum, it contains a large amount of vitamin C, as well as potassium and iron, which have a beneficial effect on the condition of all vital organs.

1. From strawberries

The benefit of strawberry jam lies in the ability of some of the substances in its composition to prevent the formation of cancer cells and help in the treatment of existing cancer tumors.

1. From blueberries

Blueberries are record holders for the content of useful substances, since in addition to a large amount of vitamin C, they contain vitamin A, which has a positive effect on vision and the health of skin, nails and hair, vitamin B, which helps normalize brain activity and the nervous system, as well as a large amount iron and manganese, which strengthen the immune system and improve overall well-being.

To quickly treat colds, it is better not to heat treat the berries. This procedure will not cause any harm, but it will also reduce the beneficial properties of the product. If vitamins B, E and PP are quite resistant to high temperatures, then vitamin C and beta-carotene are partially destroyed during cooking. Therefore, in order to achieve the desired medicinal effect, it is necessary to either use the cold cooking method or simply grind the berries with sugar.

By the way, it is a generally accepted fact that jam with seeds retains several times more useful substances than jam without seeds.

Harm and contraindications

Despite the large number of positive qualities, this product can be harmful to health if consumed in excess.

Video about the benefits and harms of jam

Blueberries are good for everyone: sweet, fragrant, healthy. One bad thing is that the collection season rarely lasts more than one and a half to two months, but you really want to feast on it all year long. And when the question arises of how best to preserve the collected berries, the first thing that comes to mind is jam.

Blueberry sweetness

Despite the fact that you can find a whole lot of recipes in cookbooks and on thematic websites, they, one way or another, belong to one of the following three types:

1. No heat treatment– the berries are ground with sugar without subsequent cooking.
2. With fast heat treatment, “five-minute” - the berries are boiled in sugar syrup for several minutes twice or thrice with an interval of 10-12 hours between cooking.
3. With long-term heat treatment- whole berries or puree from them are boiled for a long time, sometimes in several stages, to the desired consistency.

Each of these methods is good in its own way, but most of the beneficial substances found in blueberries (for example, B vitamins and vitamin C) are partially destroyed when heated, which means that the benefits become less.

Sweet tooth arguments: why is this delicacy worth eating?

Sweet lovers, remembering the dangers of sugar, always look for an excuse before putting a spoon or two of jam into their mouths. But if it is blueberry, there is no need for excuses, since this sweetness has many benefits for the body.

• Blueberries contain excess amounts of anthocyanins– vegetable dyes with antioxidant properties. They are not destroyed by temperature, which means that jam should be used to prevent cancer.
• Anthocyanins have anti-inflammatory property, therefore blueberry sweetness is an excellent auxiliary means of combating inflammation of the liver, gall bladder and genitourinary system (pyelonephritis, cystitis).
• Thanks to high content of vitamin C, blueberries ground with sugar are useful for: colds to strengthen the immune system. diseases of the gastrointestinal tract with low acidity of gastric juice. severe vitamin deficiency (scurvy).
• Blueberry jam and dishes made from it will help with treatment of intestinal disorders. Especially when it comes to thick jams or marmalade, to which pectin is often added during production.
• Does not collapse under the influence of temperature and vitamin K, which one hundred grams of berries contains a quarter of the daily requirement. This is an anticoagulant - a substance that prevents blood from clotting. Those who consume blueberry jam in large quantities are not at risk of thrombosis, and therefore the risk of heart attacks is reduced.
• Complex of tannins and acids, which also remain after cooking, with regular use strengthens the walls of small blood vessels. This is useful for the capillaries of the retina and brain, which older people will definitely appreciate - with improved blood supply to the organs, vision will fail less often, and memory will become sharper.
• Polyphenols, which are found in abundance in the skin of berries, including those that have been subjected to heat treatment, have the ability to reduce cholesterol levels in the blood.

Harmful effects of blueberry jam

With all the benefits that this delicious preparation brings, it is worth remembering that it is not a panacea. Like any medicine, it has contraindications.

Blueberries ground with sugar, as well as “five-minute”, due to the high content of vitamin C and acids (oxalic acid, nicotinic acid, also known as vitamin PP), are contraindicated for people who suffer from:

• Oxalate nephropathy(a disorder in the body of the metabolism of calcium and oxalic acid, in which difficultly soluble stones form in the kidneys and bladder).
• Pancreatitis(inflammation of the pancreas).
• Stomach problems with increased acidity of gastric juice.

At the same time, it is still possible to consume jams that have undergone long-term heat treatment, but not during an exacerbation of the disease and in small quantities

Other harmful properties:

• Allergenic substances, which are contained in the berries, do not disintegrate when heated, so the jam should not be consumed by those who have an individual intolerance.
• Due to the risk of allergies This product is recommended not to be used by women in the last stages of pregnancy and during breastfeeding. A nursing mother should introduce berries into her diet for the first time no earlier than the baby turns three months old.
• Those who are taking blood thinners should not indulge in sweets. Due to the high content of vitamin K, which performs the same function, too much is fraught hemorrhages and prolonged bleeding.
• No matter how healthy jam is, at least 50% of it is sugar. Diabetics and overweight people should limit it.

• Those with sensitive teeth should also not overdo it with berry treats. It can provoke attack of toothache, not to mention the fact that the previously mentioned acids in large quantities have a negative effect on thin enamel.
• Jam, like the berry itself, can color the skin and mucous membranes dark purple. There is nothing wrong with this, but after visiting the dentist it is better to abstain from it for a while: along with the tongue and lips, new fillings, veneers, and plastic braces can change color.

“More benefit, less harm!” - and to achieve this, very little is required:

1. For high-quality jam, it is enough to take one kilogram of blueberries 500-600 grams of sugar. More is possible, but definitely not necessary.
2. It is better to give preference to homemade grinding of berries with sugar or “five-minute grinding” rather than industrial jams with questionable composition.
3. If the existing contraindications are related to the acids in blueberries, jam from them can still be consumed in small quantities, only in the form of jams and after additional heat treatment. For example, adding tea or tea to the filling of pies.

And be sure to listen to the advice of your doctor. The benefits of candied berries are truly an order of magnitude greater than the harm, and if you use them wisely, this delicacy can significantly improve your health and improve your quality of life.

Blueberry jam will be an ideal addition to tea, breakfast, baking, or just a treat when you want something sweet. In the summer, having eaten your fill of fresh berries, you should definitely leave some for the winter to delight yourself on cold days. Jam will be an excellent way to store it, and even a beginner can make it. In addition to its bright taste, this delicacy will replenish your reserves of nutrients, especially if you cook it raw. Let's find out in more detail how to do this.

Features of blueberry preservation

If there are a lot of berries, you can use them to make any preparation for the winter: jam, compote, jam, confiture. Blueberry jam remains the most popular way to use it; it turns out to be very aromatic, bright and rich in taste.

You can buy the berry or pick it yourself; in private gardens it is a rare guest, so it is collected in the forest. Blueberries are very delicate and disappear when fresh quite quickly; it is advisable to start preparing them on the day of purchase or collection, or every other day at most. This sweetness will last longer if you use only high-quality blueberries.

If you plan to make jam with whole berries, you need to pay special attention to the quality of the fruit. Crumpled, overripe, or cracked berries will become overcooked and can even spoil the taste. For jam with whole blueberries and thick syrup, you will need firm and intact fruit. Soft, well-ripened berries can be used for jams or marmalade, but even in this case we are not talking about spoiled blueberries.

To preserve the fruits, they must be washed carefully. It is advised to put them in a colander and immerse them in a large container of water, which should be changed several times. After washing, it is advisable to dry them so that excess liquid does not get into the jam. Even a small amount of excess water can ruin the consistency and quality of the berries themselves. For convenient drying, use a simple clean towel: the laid out fruits should lie on it until they dry.

An equally important part of preparing for conservation is equipment. To prepare jam, you need to use containers made of aluminum or stainless steel. Enameled basins and pans are also suitable, but the bright pigment of blueberries can stain the enamel during the cooking process.

The volume of such dishes should not exceed 6-7 liters; it is better to prepare jam in small portions, especially if we are talking about a delicacy with whole berries. Under their own weight in a deep pan, the fruits will lose their shape and boil; at best, this will make jam, but not jam. If large-scale conservation is planned, several suitable containers will be needed to divide the total quantity into several small parts.

Blueberries are a fairly sweet berry, so you will need a little sugar: per kilogram of berries you need 500-700 grams of sugar. Sometimes a larger amount of refined sugar is used, but such a delicacy is suitable only for those with an avid sweet tooth, since the taste will be very sugary.

Glass containers and lids for preservation must be sterilized. This can be done using boiling water or steam; you can also use a microwave. All jars and lids must be dry before screwing to prevent raw water from entering the product.

Cooking process

So, from prepared and washed blueberries you can make many options for jam for the winter. Among this variety there are the most popular ones, which are distinguished by their taste, preservation of benefits and ease of preparation. Let's look at how to cook this “delicacy”.

Blueberry jam with whole berries

For this you will need:

• 5 glasses of berries;
• 3 cups granulated sugar.

This recipe is also called “five-minute”, it is very simple to follow, and preparation takes a minimum of effort. The prepared berries need to be placed in a container where the future jam will be prepared - five minutes. Cover the blueberries with sugar and leave them to soak and release juice, this will take about 3-4 hours. The fruits produce quite a lot of juice, so additional water is not required.

When the contents are infused, the berries should already be covered with a bright liquid, and the sugar should be half dissolved. After this, you need to put everything on low heat and wait for it to boil. After boiling, the jam should stand on the fire for another five minutes, it should be quickly put aside and packed into jars. This simple recipe for jam with whole berries will preserve the vitamins in blueberries that you will really need in winter.

Raw blueberry jam

• 500 g berries;
• 250 g sugar.

Blueberries need to be mixed with sugar; in this preparation, you can take an absolutely arbitrary amount of refined sugar - as you like. Next, you need to mash the ingredients with a wooden masher; for convenience, you can use a blender. To grind blueberries, you can pass them through a meat grinder, and then mix them with granulated sugar.

The finished mass is blueberry jam without cooking. Place it in clean jars, but do not fill them completely. Sprinkle a 1-1.5 cm layer of sugar on top of the jam. Then they are covered with a nylon or metal lid. This delicacy should be stored in a cool place, and if nylon lids were used, be sure to store it in the refrigerator.

Blueberry jam

Ingredients:

• 4 cups of berries;
• 2 cups sugar;
• gelatin.

Washed and dried blueberries need to be finely chopped; for this you can use a blender or pass them through a meat grinder several times. It is necessary to obtain a puree of homogeneous consistency; sugar is added to it. The ingredients should sit at room temperature for a couple of hours so that the crystals dissolve and blueberry juice appears.

After the allotted time, the consistency will become thicker and darker.

The bowl with the future jam needs to be put on the fire, while everything is slowly boiling you can do the gelatin. For the indicated amount of ingredients you will need half a standard pack, it should be diluted in water as indicated on the package, the finished gelatin mass should be without lumps. Add water and gelatin to the boiling jam and mix everything well. After boiling, cook for another 5-7 minutes and place hot into jars; glass containers should also be warm.

Blueberry jam in a slow cooker

To prepare we will need:

• blueberries – 4 cups;
• sugar – 2 cups.

Place clean and dry berries in a multicooker bowl, sprinkle them with sugar and stir. You can prepare the jam right away; to do this, select the stewing mode and leave the contents of the bowl to simmer. Periodically you need to stir the dessert with a spatula so that it does not spoil from the burnt smell and taste. In this mode he will need 1-1.5 hours.

At the end of cooking, you need to check the jam for readiness: you need to drop a little syrup onto a cool plate, if it holds its shape and does not “float” - everything is ready. If the droplet spreads, set it on the same mode for another 15-20 minutes. Its thickness will depend on how long to cook this sweetness. This delicacy needs to be served hot.

In addition to a multicooker, such a sweet can be easily prepared in a bread maker; most of them have a “jam” mode. Standard proportions of ingredients are placed in the device and cooked until thick. The result is such a tasty and healthy delicacy, but with less time.

It’s even easier to use an air fryer: mixed berries with sugar are placed directly into sterile dry jars. Filled containers should be placed in a convection oven and the temperature should be set to 1800. This jam can be prepared in just half an hour at high speed.

If you didn’t have time to make preparations for the winter in the summer or you simply don’t want to preserve jam, you can simply freeze the berries. These blueberries will make equally tasty jam, which can be prepared in the microwave in winter: the berries mixed with sugar just need to be heated for 10 minutes - a fresh and aromatic delicacy is ready.

Calorie content and chemical composition

Fresh blueberries are low in calories - only 44 kcal. But jam contains almost half of the sugar, so the calorie content of such a product will increase. If you use classic proportions (one part berries and half part sugar), the energy value of the product will be 250 kcal. Jam can be prepared without sugar, its preservative properties will be replaced by Zhelfix, the calorie content of such sweetness will be almost 100 kcal for every 100 g of jam.

Why did the blueberry jam turn out runny?

How to cook blueberry jam so that it turns out thick? Many novice housewives ask this question. First you need to understand the reasons why the jam turns out liquid.

1. It is better to cook blueberry jam in a basin rather than in a saucepan. The surface area from which water evaporates can play a large role in the thickening of the jam.
2. The amount of sugar is important. Many housewives advise maintaining a berry-sugar ratio of 1:2 - take two measures of sugar for one measure of blueberries. You can reduce the sugar content to 1.5 measures. But you definitely shouldn’t take less than 1:1. Otherwise, you risk getting syrup instead of jam.
