Can the temperature of food change its nutritional value? Yes, it affects digestion time, absorption of nutrients, vitamins and minerals.

The difference between cold and hot food: digestion

Digestion can be improved in several ways, for example, eating with feeling, sensibly, sparingly, chewing food thoroughly. And another life hack is to prefer cooked vegetables and fruits to raw ones.

Digestion of a raw and cold carrot or apple begins in the mouth, but the whole process takes longer than in the case of cooked food. And during heat treatment, for example, baking, the chemical compounds in apples begin to disintegrate even before they enter our body. And when we eat them, we absorb beneficial nutrients more easily - thus increasing the nutritional value.

Raw or cooked hot vegetables?

By the way, many people believe that raw vegetables and fruits contain more vitamins than cooked ones, but this depends on the type of nutrients.

A study published in 2002 by the Journal of Agricultural and Food Chemistry found that cooking vegetables such as tomatoes increases their lycopene levels. During the study, 200 people if raw vegetables and fruits, as a result of this diet, subjects had higher than average levels of beta-carotene (a precursor to vitamin A), but much lower than average plasma levels of lycopene (another “version” of the vitamin, an isomer of beta-carotene). And this is not surprising, since Fresh tomatoes have lower levels of lycopene than cooked tomatoes.. Roughly speaking, during the process of cooking fruit, the cell walls of the plants are “broken” and the nutrients stored in them are released.

Let us remind you that lycopene, which is found in tomatoes, watermelons, red peppers and papaya, reduces the risk of developing cancer and heart attacks. But there is also a minus: when vegetables are heated, they lose a significant amount of vitamin C, an extremely useful antioxidant that improves the functioning of the immune system.

Water: should you drink it cold or hot?

Cold water - in addition to being cooling and refreshing - is absorbed much faster and is more helpful in avoiding dehydration. In addition, the body spends a certain amount of calories heating it. Recall that 1 calorie is the energy required to heat 1 ml of water by 1 degree. Accordingly, 1 kcal = energy to heat 1 liter by 1 degree. In other words, to heat a liter of water at room temperature to 36.6, the body will need about 16 kcal.

On the other hand, warm drinking has its advantages, for example, it improves digestion.

Cereals: Hot porridge retains nutrients

When comparing cereals, other factors must be taken into account: ready-made cereals (which are usually filled with cold milk) are most often covered with a sugar crust and have already lost a bunch of useful nutrients during processing.

If you can’t give them up, then look for ready-made breakfasts with low sugar content and high fiber content.

But in hot versions, for example, oatmeal contains vitamins and minerals in their natural form, plus fiber, which satisfies better and saves you from hunger longer, that is, it helps you eat less, and therefore control your calorie balance.

Is cold food harmful?

In the hot season - and in the era of smoothies - we swallow ice-cold liquids every day, and even in cold weather, wrapped in a blanket, we continue to sip something with ice. But is it really good for your health?

Unfortunately, there is little scientific data on this issue, but here is traditional medicine(Indian and Chinese) does not recommend eating chilled food. Indian and Chinese traditional medicine recommends eating food at at least room temperature at any time of the year: colder food can cause hormonal disorders, skin diseases, bloating, digestive problems and even affect the psyche, worsening depression and anxiety.

3 reasons to avoid iced drinks and frozen food:

1. Digestive system

The temperature of food affects digestion, and even cold liquids—especially on an empty stomach—can cause problems. Some people have a glass cold water in the morning can lead to swelling, bloating and upset digestion for the whole day. Drink water at room temperature or warmer.

1. Hormonal system

Eating cold foods in autumn, winter and spring can lead to hormonal imbalances, symptoms of which may include irritability, weakening hair, hyperacidity, swelling and skin rashes. Warm food is healthier at these times of year.

1. Fertility

Warm food is easier to digest and supplies more beneficial nutrients - which is especially important for conception and pregnancy. From frozen food and ice-cold drinks (including your favorite smoothies), the body becomes numb and loses strength, lacking nutrients. Hot meals help women's health reproductive system, maintains normal menstrual cycle and relieves PMS symptoms by improving hematopoietic processes.

What same do : Avoid cold foods: frozen fruits and berries, cold salads and sandwiches, iced drinks. Eat hot broths and puree soups, bake meat and vegetables, prefer warm drinks and add warming herbs and spices - ginger, turmeric, cinnamon.

Do we need hot food?

Greetings, dear friends. Today I bring to the attention of readers information that answers the question: is there any benefit to a person from hot food?
Of course, everyone chooses for themselves - to agree or argue. I completely liked the arguments presented below.
I wonder what you will write in the comments after reading the material!

Many people, following years of established dietary traditions, eat very hot food that is 80 and even 90 degrees.

As you know, protein denatures (loses its natural properties) at a temperature of about 60 degrees Celsius. This means that hot food causes the stomach cells that produce gastric juice to denature protein.
As a result, the cells of the stomach cease to fulfill their role - to produce gastric juice and food ceases to be broken down.

In turn, gastric juice consists of pepsins - enzymes that process animal protein and of hydrochloric acid. Why does the human stomach have these pepsins if we say that we need to eat plant foods?

Scientists have calculated that the human body is home to up to 900,000 species of different microbes, the number of which is billions.

By the age of 50, they account for almost half the weight of the human body, since the stomach, spoiled by hot food, cannot withstand them.

Stomach cells live for three days. After three days, if they are not killed by hot food, they divide, as a result of which they are rejuvenated and again become capable of producing normal gastric juice.

But people eat hot food two, three, four, or even five times a day, and they also drink hot drinks.
Therefore, the cells of the stomach have no chance to maintain their functions and over the years they disappear completely, the cells degenerate and can no longer secrete normal gastric juice.

In this regard, most people have low or even zero stomach acidity. With zero stomach acidity, the natural barrier against microbes can be considered completely eliminated.

Such a stomach is sluggish, the sphincter separating it from the duodenum is constantly open and enters duodenum bile flows freely into the stomach, causing heartburn in a person.

How to write correctly

Academician B.V. Bolotov

Heartburn is a sign of low acidity, and high acidity simply cannot exist by definition. And any heartburn can be easily relieved with a tablespoon of diluted vinegar.

Food that is indigestible in the stomach, even if it is raw food, passes through the intestines, is processed by protozoa, becomes dead, with the same properties as boiled food, i.e. causes food leukocytosis.
And just like boiled food, it clogs all filtering organs.
Therefore, if you have switched to a raw food diet, and you have zero acidity, you need to help your stomach - include acidic foods in your diet, add vinegar and citric acid to salads. B.V. Bolotov even recommends a weak solution of hydrochloric acid (0.3%).

Summing up what has been said, I would like to remind you that a person can heat the food he eats for better dissolution or interaction up to 50 degrees, and preferably up to 47. But food should enter the body at a temperature no higher than 42°C, above which, as is known, a person dies, because enzyme denaturation begins.

Today we talked about whether a person needs hot food; how it harms the stomach and why you can’t eat hot food.

When writing the article, materials from the works of B.V. Bolotov and V.A. Shemshuk were used.

Do you share the opinion expressed in the article? What kind of food do you prefer to eat - hot or not?

With wishes of harmony and joy in your life,

Is it healthy to eat hot food? Excessively hot first courses (soups, borscht, broths) burn the mouth, the mucous membrane of the lips, and can provoke excessive salivation and vomiting. All this can subsequently cause the formation of ulcers, gastritis, stenosis (narrowing of the larynx), experts explain.

Temperature. The human body tolerates food that is not too hot and not too cold. When consuming very hot or cold food and drinks, the epithelial tissue of organs is affected, and this leads to cancer diseases.

“Cold food is divided into 2 types: fresh cold, which has not been processed, and boiled, but chilled. Thus, heat treatment helps kill pathogenic microorganisms. That is, moderately cold food does not harm the human body, but warm food is most beneficial for the stomach and spleen. About 20-30 degrees,” say nutritionists.

Esophagus burn. Food that is too hot burns the esophagus. The walls of the esophagus are affected, and necrosis of the esophageal tissue may occur. This causes tissue swelling and difficulty swallowing. Later, the process of rejection of dead tissue begins, ulcers form, and after their healing, the formation of a narrowing of the esophagus (stenosis) begins.

Burn of the pharynx and oral cavity. Hot food can also cause burns to the mouth and pharynx, mucous membranes of the lips and mouth. After such defeats you will not be able long time eat food, as ulcers form in their place. A few days after the burn, a person can eat liquid food in small quantities. A scar forms in the pharynx and lips; it leads to a decrease in the lumen of the esophagus, and this is dangerous because it causes obstruction of the esophagus.

Exhaustion and other consequences. Experts note that hot food can cause exhaustion due to malnutrition after burns. Pneumonia, tracheobronchitis, laryngitis and periesophagitis also sometimes occur.

Hot for children. It is very dangerous for children to eat too hot dishes, as even minor burns to the mucous membrane of the esophagus, pharynx, larynx, oral cavity can cause serious consequences: respiratory distress, laryngeal stenosis, difficulty in expectoration, impaired swallowing functions.

About cold drinks. Experts say that cold food leaves the stomach too quickly, without having time to mix properly with gastric juice. This leads to putrefactive processes, which result in increased gas formation, intestinal dysbiosis, peptic ulcers and enterocolitis.
Fast foods most often offer very sweet carbonated drinks, always with ice, rather than tea or coffee.

It is impossible to quench your thirst with such drinks; moreover, as it turns out, they increase your appetite. Consequently, those who like very cold drinks often suffer from obesity, nutritionists warn. Go to Home Page

The degree of denaturation of food is affected by heat treatment time and temperature (we do not consider pressure and similar factors). Protein used in our body denatures (changes structure and properties) when heated above 45 degrees. The longer the heating time and the higher the temperature, the more detrimental this is to the product. Heating animal products up to 45g. should not cause much concern.

In general, it is advisable for any food entering the body to have a body temperature - 36-38 degrees. It is at this temperature that most reactions (including digestive ones) involving enzymes occur, because the latter operate at relatively small temperature fluctuations.

digestion

And high levels destroy the enzymes themselves.

Different times for food digestion in the stomach or why does taking cold food into the stomach harm the gastrointestinal tract?

Warm food in the stomach is digested for about 2-3 hours and only after that it enters the stomach. small intestine, where the stage of breakdown of nutrients from food continues. Two to three hours is the optimal time for digesting food in the stomach and breaking down proteins. This is the norm, since when undigested proteins enter the small intestine, the fermentation process begins.

Digestion of food in the stomach must occur around the above time, otherwise we not only do not benefit from nutrition, but also harm our digestive tract.

Cold food in the stomach is digested much faster: proteins do not have time to be properly digested and are sent straight to the small intestine, the function of which is based on the breakdown and absorption of carbohydrates, since it is in it that the bacteria responsible for this “event” are located. As a result of undigested food in the stomach (proteins) entering the small intestine, proteins, of course, are not absorbed normally. In addition, bacteria living in meat products (proteins) begin to multiply, which leads to various types discomfort in the gastrointestinal tract (bloating, gas, constipation, etc.).

ABOUT proper nutrition and the fact that the time of digestion of food in the stomach depends on its temperature began to be talked about back in the 20th century, but, unfortunately, the discovery of scientists is rarely of interest to people, much less the fast food industry. People regularly eat hot hamburgers and wash them down with cold Coca-Cola. Hence the problems with obesity and all kinds of gastrointestinal health problems. Nutritionists call for healthy eating In addition, they very often say that food in the stomach must be digested normally, indicating what requirements exist for this.

Of course, nutritionists do not deny that it is sometimes possible to pamper your stomach; cold food in the stomach (ice cream) occasionally does not threaten anything, but regular consumption threatens not only with improper digestion of food in the stomach, but also with the development dangerous diseases Gastrointestinal tract.
If you constantly put cold food into your stomach, then you are guaranteed problems and discomfort. In addition, rapid digestion of food in the stomach contributes to the gain of extra pounds, since after an hour or an hour and a half you will want to eat again, and your stomach has not given your body the long-awaited proteins. This means that now you need to replenish their stock again.

When it comes to proper nutrition, we usually mean healthy and varied dishes. At the same time, few people think about the temperature of the food they eat.

Of course, food that is not too hot and not too cold will be normal for the body, due to the fact that our mucous membrane and all organs are not adapted to very hot food, as well as to very cold food. This is due to the fact that it begins to be affected epithelial tissue organs, which can lead to irreversible processes, even cancer; this is the danger of cold and hot food.

Most people love to drink cold drinks (ice juices, cocktails), and almost no one ever refuses ice cream. But the fact is a fact: ice-cold drinks and cold food lead to obesity. Back in 1969, Soviet radiologists established this fact by conducting the following experiment: patients were given barium porridge for x-rays, but the porridge left the stomach faster than the radiologists had time to set up the equipment for the image. Upon closer examination, it turned out that if you wash down food with cold drinks (for example, ice water or Pepsi-Cola with ice), the time the food spends in the stomach is reduced from 4-5 hours to 20 minutes.

Thus, when eating cold food or cold drinks, normal digestion does not occur. This naturally leads to obesity, because... It is impossible to get enough of such food and the feeling of hunger comes faster. Such food enhances the processes of putrefaction in the intestines, thereby disrupting the healthy processes of absorption and utilization of food.

In the stomach, proteins are prepared for subsequent processing and absorption.

Therefore, attention! If you drink any cold drink after a meal, the protein part of the food will not be fully processed in the stomach, the proteins will not be broken down into amino acids. The bolus of food will quickly leave the stomach, and the entire protein component will simply rot in the intestines (unprocessed protein at a temperature of 36.6 degrees begins to rot relatively quickly).

You will not only waste money on food, but instead of benefit you will get harm in the form of intestinal inflammatory diseases(colitis, enteritis) and dysbacteriosis.

This reaction of the body to cold drinks is widely used by fast food establishments. Have you ever wondered why in such establishments there is always ice water on the table? This is not at all for you to quench your thirst. After drinking ice water, you will begin to experience an increased feeling of hunger, which you will then quickly satisfy with fast food. Ultimately, this leads to disruption of everything gastrointestinal tract, as well as gaining excess weight.

Eating hot food is no less dangerous. This topic is especially relevant for those who like to drink very hot tea in large doses. All scientists say that hot food burns the esophagus, and in this case severe damage to the wall of the esophagus occurs, the depth of the damage itself depends on the hot food drunk. With burns of the esophageal mucosa, necrosis of the mucosa, as well as other layers of the lining of the esophagus, occurs. Such phenomena lead to the development of swelling of the tissues of the esophagus, and at the same time swallowing is impaired, but subsequently the swelling decreases significantly, but dead tissue begins to be rejected, which leads to the formation of ulcers, after their healing, stenosis or narrowing of the esophagus is formed in the esophagus - this is the danger eating hot food.

Thus, we can conclude that the danger of eating hot and cold food is obvious, such food is harmful to health and you should only eat food at normal temperature.

In modern medical practice, complete or partial loss of taste is often encountered. All these cases are associated with various malfunctions that occurred in the human body. But most often they are found in otolaryngology. It is during an appointment with this specialist that patients often ask: “What to do if you no longer feel the taste of food?” After reading today's article, you will understand why such a pathology occurs.

Causes of the problem

Oddly enough, but most often this pathology develops as a result of neurosis. This is a peculiar reaction human body to stress and nervous overload. In these cases, you can hear from the patient not only the phrase “I don’t feel the taste of food,” but also complaints about malfunctions of the gastrointestinal tract, jumps blood pressure, and rapid heartbeat.

An equally common cause of this problem is considered to be infectious diseases oral cavity or the presence of a decaying dental nerve. In this case, an inflammatory process begins in the human body, affecting

Also, such a pathology can be a consequence of malfunctions of the thyroid gland. Even minimal deviations can lead to serious changes in many systems of the human body.

Doctors often hear the phrase “I can’t taste food” from those diagnosed with a brain tumor. In this case, this symptom may alternate with a feeling unpleasant odor. So, a well-prepared dish made from quality ingredients suddenly begins to seem stale.

Which specialist should I contact with a similar problem?

Before you go to the doctor’s office and voice your complaint “I can’t taste the food” (the reasons why such a pathology occurs were discussed above), you need to understand which specific doctor you need to see. In this situation, much depends on what associated symptoms accompanied by this pathology.

If, in addition to loss of taste, the patient complains of decreased appetite, rapid heartbeat and racing blood pressure, then he definitely needs to consult a neurologist.

In cases where the pathology is accompanied by dizziness, weakness, vomiting, impaired hearing and coordination of movements, you should first make an appointment with an oncologist.

If a person utters the phrase “I don’t feel the taste of food,” complains of nausea, vomiting, heartburn and sharp pain in the epigastric region, it is likely that he needs to examine the gastrointestinal tract.

If familiar foods seem bitter, and every meal is accompanied by the appearance of painful sensations in the right hypochondrium, then you need to visit a hepatologist. It is possible that loss of sensitivity of taste buds, accompanied by flatulence, defecation disorders, insomnia and irritability, is a consequence of cholecystitis.

Diagnostic methods

The person who applied for medical assistance and the person who voiced the phrase “I don’t feel the taste of food” will need to undergo several additional studies. They will allow you to establish the exact cause that provoked the development of the pathology and prescribe adequate treatment.

First of all, the specialist must determine the threshold for sensitivity. To do this, the patient is alternately asked to determine the taste of quinine hypochloride, sugar, table salt and citric acid. The results of the study allow us to create an accurate clinical picture and the scale of the problem. To determine the qualitative threshold of sensations, a few drops of a special solution are applied to individual areas of the oral cavity.

In addition, modern doctors have the opportunity to conduct electrometric studies. The patient is also prescribed a number of laboratory tests. They are needed to exclude endocrine diseases. In most cases, the patient is sent for a computed tomography scan.

Why is this pathology dangerous?

It should be noted that it can cause the development serious problems with health. A person who begins to wonder: “Why can’t I taste food?”, in the absence of proper treatment, may subsequently be diagnosed with diabetes, cardiovascular and other diseases.

Disruption of the receptors can result in a person consuming too much salt or sugar. These attempts to improve the taste of food can lead to serious problems. They often lead to depression, hypertension and diabetes.

What to do if you can't taste food?

First of all, you need to make an appointment with a doctor and undergo all the tests he recommends. This will allow you to determine the root cause of the problem and prescribe the correct treatment.

So, if the problem was caused by neurosis, the patient will be recommended to undergo an individual course consisting of auto-training, water and magnetic therapy. He will also be prescribed sedatives. herbal teas, and in more serious cases - tranquilizers or bromides. If the reason lies in a malfunction of the thyroid gland, then endocrinologists usually prescribe drugs to replenish iodine deficiency.

To improve your taste sensitivity, you need to quit smoking. Often it is this bad habit that causes such problems. Also, taste sensations may be dulled while taking certain medicines, including strong antibiotics. In this case, you need to consult a doctor so that he can recommend other medications that do not have such side effects.

In addition, you should make sure that your body receives a sufficient amount of vitamins and microelements. To do this, you need to introduce more fresh vegetables and fruits into your diet. If you lose taste, you should not overuse spices. Otherwise, you risk getting a burn to the oral mucosa.
