Potatoes: chemical composition and calorie content
The potato is a tuberous plant in the Solanaceae family. It is valued for its taste and variety of dishes prepared from it. However, few people know that the calorie content of potatoes in each case is different. What is the nutritional value and the number of kilocalories in a vegetable of a different type, we will consider further.
Nutritional value (BJU)
Potatoes are often compared to bread, as today they make up the bulk of the human diet. One hundred grams of a vegetable crop contains 21.55 g of carbohydrates. Fats are 0.1 g, proteins 1.96, water 75.42 and the remainder is ash. The amount of protein in it is approximately 3% of the daily requirement of the body.
Considering KBJU, it is worth noting that the nutritional value of the culture may vary depending on its preparation. For example, a fried product has more dietary fiber and fat. Per 100 grams, there are about 24.7 g of carbohydrates, 10.3 g of fat and 3.5 g of protein. A baked vegetable is half as much in terms of energy value, it contains no more than 17 g of carbohydrates, while fats account for 0.8 g, and 2.2 g for proteins. According to its properties, it is considered more useful than a frying product.
Due to the high concentration of carbohydrates for dietary nutrition, it is necessary to think over the basis of dishes in a special way, since culture cannot form the basis of the daily diet.It is good for treatment (for example, diseases of the digestive system), but it is not at all designed for weight loss.
Chemical composition
The chemical composition of potatoes is characterized by the presence of vitamins and minerals, it includes amino and organic acids, dietary fiber, pectin, fiber and starch. It includes fat-soluble vitamins E and K, as well as water-soluble B vitamins (B1, B2, B4, B5, B6, B9), PP, biotin, ascorbic acid. Regardless of the variety of variety, the following minerals are present in each potato:
- calcium;
- iron;
- iodine;
- fluorine;
- cobalt;
- nickel;
- rubidium;
- magnesium;
- phosphorus;
- potassium;
- sodium;
- zinc;
- copper;
- manganese;
- selenium.
The total amount of sugars is 1.7 g, fiber - 1.5 g. An interesting nuance is the fact that the amount of vitamin C has a higher percentage in fresh vegetables. As a rule, by spring it remains no more than 1/3 of the original amount. It is also important to consider the variety of the crop, since the amount of beta-carotene in it is also not the same.
In addition to starch, the vegetable also contains other digestible carbohydrates (dextrins, mono- and disaccharides, glucose, sucrose and fructose). It also contains essential amino acids: leucine, lysine, valine, arginine, phenylalanine. The essential acids that make up the vegetable include serine, proline, alanine, glutamic and aspartic acids.
The number of calories in a vegetable
The energy value of a vegetable crop differs depending on the method of its preparation. For example, for raw white tubers with skin, it does not exceed 70 kcal, while for baked potatoes with skin, it will already be 94 kcal. For mashed potatoes, this figure is usually 100 kcal, for fried potatoes - about 149 kcal.Boiled potatoes with salt are slightly higher in calories than mashed potatoes made with whole milk. In the first case, the energy value is 87 kcal, in the second - 83 kcal.
If mashed potatoes are prepared with the addition of milk powder, the number of kilocalories will increase to 105. The calorie content of young potatoes is 77 kilocalories, boiled without skin and pickled - 86 kcal each. In addition, the value varies depending on the variety. For example, the red variety has 72 kilocalories with the peel fresh and 89 when baked.
Sweet potato accounts for 60 kcal, yams - 118, purple - 72. Most of the calories are found in potato flakes: there are about 369 of them per 100 product. The dried analogue contains 317 kcal, frozen fries - 260, fries - from 167 to 199 kcal. The type of cooking is also important: for example, if a vegetable in a uniform is baked in a microwave without adding salt, it will contain about 132 kilocalories. If it is salted, the energy value will decrease to 105 kcal.
If the vegetable is breaded and cooked with oil, its calorie content will increase to 132 kcal. Dry uncooked breaded product can have up to 314 kcal. Frozen slices have 123 kilocalories.
Thus, we can conclude that young and raw potatoes have fewer calories. Fried and fries - the most high-calorie, baked and boiled have a different amount, which depends on other food components, as well as salt.
Beneficial features
Despite the conflicting opinions about the potato, it has many useful qualities, due to its chemical composition. The reason for the harm lies, first of all, in the wrong approach to cooking a vegetable. However, due to potassium, it has a beneficial effect on the functioning of the cardiovascular system.At the same time, doctors note that a baked vegetable has more potassium.
According to the available reviews found on the Internet, the peel of the plant is also useful. Considered a source of vitamins and minerals, it has an active effect on potency. Other qualities include the ability of the culture to accelerate the healing of wounds and burns, in addition, it has antibacterial properties. To do this, it is enough to grate a fresh potato or chop it in a blender and apply it several times to a sore spot.
Potato juice is also useful, as not only traditional medicine claims today. Doctors use it as a medicine in some cases, for example, for heartburn and exacerbation of chronic gastritis, as well as stomach ulcers in remission. To do this, they usually drink it in a course of 1 glass per day. Potato juice also helps with apathy, depression, diarrhea, constipation, intestinal colic.
Potatoes are characterized by the ability to stimulate human brain activity. Its use favorably affects the functioning of the kidneys, water metabolism, the functioning of the nerves, as well as the condition of the teeth and bones. When properly prepared, it can remove toxic substances and toxins from the body, as well as strengthen the immune system. At the same time, it will not affect weight, but will saturate the body with essential minerals and a vitamin complex.
Due to its composition, the potato also benefits the thyroid gland, and in addition, it improves the composition of the blood and helps strengthen the walls of blood vessels. This is a good regenerative agent that puts muscle tone in order, participates in the normalization of water-salt metabolism and slows down aging.Its moderate use increases the body's resistance to stress, normalizes sleep patterns and improves the condition of the nail plates.
A boiled vegetable in hot and mashed form, in addition to treating eczema, perfectly eliminates cough. Raw potatoes are effective for burns, as well as fungal infections of the skin. In addition, the culture, regardless of its calorie content, is used to eliminate age spots. It eliminates excessive greasiness of the skin, makes the epidermis matte and toned.
Harm
Do not eat green potatoes due to the presence of solanine in them. This is especially true for pregnant women, since this poison can provoke violations of the intrauterine development of the baby. It is unacceptable to include potatoes in the diet, regardless of its calorie content, when a person is diagnosed with gastritis with low acidity. It is not recommended to eat a vegetable for diabetics and those who have pancreatic diseases.
To get an idea of the difference in the number of calories per 100 grams, you can give a few examples of dishes. So, potatoes baked with minced meat raise their rate from 77 to 180 kcal. If you replace minced meat with chicken eggs and cream, the energy value will drop to 120 kcal per 100 grams. When a vegetable is boiled, its value increases slightly. However, if at the same time the dish is seasoned with oil, it increases by 40-50 kcal.
With regards to fried potatoes, it can be noted that it is harmful due to carcinogens formed in the oil at the time of cooking. If at the same time mushrooms are added to the recipe, the energy value will be 200 kcal. Adding meat will increase its nutritional value, and at the same time its carcinogenicity. Such a potato will have a calorie content equal to 260-280 kcal.The worst calorie catalyst for fried potatoes is lard. Such a dish will weigh about 350 kilocalories for every 100 grams.
If we talk about various potato dishes, the calorie content of the product will be:
- soup - 40 kcal;
- casseroles - 110 kcal;
- draniki - 268 kcal;
- zraz - 268 kcal;
- baked pies - 150 kcal;
- fried pies - 185 kcal.
An example is the energy value of potato chips. For different manufacturers, it varies from 510 to 540 kcal. Of course, in comparison with them, homemade chips will be less harmful, but this does not mean at all that they are useful.
If you really want to do something similar, you should replace the pan with a microwave. This will reduce the calorie content to 120 kcal.
How to reduce the energy value?
Today it is difficult to find a person who refuses to eat potatoes altogether. At the same time, boiled potatoes or a steamed product have the least calories.
You can reduce the number of calories by carefully choosing the ingredients of the dish, as well as how it is cooked. For example, the same mashed potatoes will have fewer calories if raw chicken eggs and vegetable oil are used instead of milk and butter. At the same time, you should not oversaturate the dish with oil: everything should be in moderation (the less oil is used, the lower the calorie content will be).
You can reduce the number of kilocalories by choosing a recipe for cooking potatoes in their skins for a couple or baking. Prepared by this method, it will be beneficial for the body and can be used as a dietary food. In the process of cooking, starch under the influence of temperature and when saturated with water will turn into useful fiber.Such food will not only be low-calorie: it will favorably affect the functioning of the digestive system. In addition, it will stimulate the synthesis of vitamin B2, which is responsible for reducing the concentration of cholesterol in the blood.
You can reduce calories by reducing portions. There is no need to consume more than 300 g of potato dishes per day. This amount is quite enough to fill the body's daily need for carbohydrates, phosphorus and potassium. An effective measure to reduce the calorie content of food will be the rejection of mayonnaise and sauces.
You can reduce the amount of oil when frying by using good dishes. For example, if you buy a pan with a non-stick coating, this will reduce the amount of cooking oil. So it will need a little more than 1 tablespoon per total. If it seems to someone that this amount of oil is too much, after cooking, the dish can be thrown into a colander, allowing the excess oil to drain.
You can reduce the energy value of a raw peeled vegetable by soaking it in water for about 20 minutes after removing the skin. A potato crop will be useful and low-calorie if you cook it from a soaked vegetable, dipping it for cooking not in cold, but in hot water.
diet recipes
Nutritionists pay attention to the fact that you can not mix proteins with carbohydrates. This is due to the fact that they are absorbed by the body in different ways. It is not recommended to eat potatoes and meat, chicken, fish, and dairy products together, even if the basis of the diet is a boiled vegetable. It goes better with zucchini, cabbage of any variety, green peas, carrots and herbs.
Eat potatoes preferably in small portions, which can be divided into two doses.At the same time, it is better to eat it in the first half of the day, which will create a feeling of fullness in the body and will not affect weight gain. After 4 p.m., the rate of carbohydrate breakdown decreases significantly. Therefore, the body does not have time to spend the energy received as a result of eating. Therefore, everything will go to the fatty layers.
To help your body, it is preferable to eat potatoes for breakfast and lunch. You should immediately decide on the type of dishes: the diet does not include fried potatoes, and even more so french fries and homemade chips. It is also worth abandoning the stew and dishes with the addition of meat.
Attention should be paid to simple recipes. For example, a dietary product is boiled potatoes, as well as mashed potatoes cooked in water with the addition of vegetable oil. A good option for a diet would be a baked vegetable with a peel. However, in this case, moderation is especially important: you can not eat more than two potatoes with peel per day.
There are special diets based on potatoes. Usually their duration is from one to three days. This can be a mono-diet, in which, in addition to potatoes, they drink water or kefir. As a rule, the potatoes are not salted and flavored with oil. In another type of diet, you can drink milk, eat potatoes boiled in water, not supplemented with butter, and boiled eggs.
Often, such diets allow you to reduce weight and eliminate excess fluid in a few days. In addition, they well eliminate puffiness and cleanse the intestines. However, in order for the sense of eating potatoes to be, you need to cook it correctly. For example, the most common recipe for cooking diet food is potatoes in a double boiler. It's simple, healthy, and low-calorie.
It is noteworthy that you can steam not only peeled potatoes, but also root vegetables in their skins. As a rule, such food has an excellent taste, allowing you to add spices already on the plate, and thereby reveal their aroma to the maximum extent. If you want to bake potatoes, not a fire or barbecue is perfect for this, but an ordinary oven.
The main rule of the diet recipe is the absence of oil, meat or bacon in the dish. For example, an interesting and tasty dish can be prepared by peeling potatoes, wrapping them in foil, after sprinkling with lemon juice and olive oil in the form of a spray (this reduces consumption). To add flavor, you can add fresh herbs to the dish.
Someone makes the so-called French potatoes in the oven, cutting them into slices, adding lemon juice and mustard. It is laid out on a baking sheet and cooked without oil. When you need to cook a delicious boiled product, the vegetable, after soaking, is placed in new clean water, to which carrots are added. To taste, you can improve the recipe with onions.
You can also make a casserole from potatoes, and with a lighter calorie content. To do this, preheat the oven to 250 degrees, boil water in a saucepan. Potatoes are peeled and cut into circles of small thickness, then placed for 5 minutes in boiling salted water. You do not need to cook them until fully cooked.
Then the water is drained, potato mugs are seasoned with a small amount of olive oil and ground pepper. In order for everything to be evenly distributed over all the circles, it is better to mix the dish with your hands. After mixing, take half the slices and lay them out on a baking dish. From above they are supplemented with horseradish and covered with the remaining circles. Bake the dish for no more than 20 minutes.
If potato juice is used for food, to improve its taste, you can supplement it with carrot juice or even a drop of honey. This not only does not harm health, but also enhances the effectiveness of the product. The only thing to consider is that this product is prepared immediately before use. It should not stand for more than 5-10 minutes.
What else to consider?
Frozen potatoes are used in catering, but for home cooking it is harmful. This is explained by the fact that starch crystallizes when frozen, it is difficult for the body to digest it. When this product is fermented in the colon, the functions of bacteria that burn carbohydrates are blocked. That's why regular cooking from frozen potatoes contributes to obesity.
If you absolutely cannot do without french fries, you should cook it in a deep fryer. Thanks to modern developments of manufacturers, no more than one tablespoon of vegetable oil will be needed for cooking in this device. Such potatoes in finished form will contain no more than 3% fat. It is better to cook a boiled dish from a young vegetable.
You can not combine potatoes with tomatoes, as they contain a lot of acids that destroy ptyalin (an enzyme that promotes the absorption of carbohydrates).
Do not forget that potatoes alone cannot reduce weight and improve the condition of the body. Calorie calorie content, however, human food should be varied. In order not to harm your health, it is better to limit yourself in its quantity than to reduce the variety of products.It is impossible, for example, to expect that eating potatoes alone can strengthen the immune system when, in addition to this vegetable, it needs other products that can replenish and saturate the body with those substances that it lacks.
