What are the adverse effects of pure sugar? Decreased brain activity

Today, only lazy people don’t talk about the dangers of sugar. And they called it white death, and sweet, and many other epithets. But at the same time, the vast majority of people persistently consume kilograms of sugar, snatching it up on store shelves and generously flavoring it with it. great amount homemade dishes.

What is this - mania or necessity? Let's figure out whether the body needs sugar and whether it brings at least some benefit, or is it really the source of many terrible diseases.

What does sugar consist of?

Sugar is a complex of two elemental sugars – glucose and fructose. When combined together, two molecules of these substances form a larger sucrose molecule. And already many molecules of sucrose, stuck together, create a white grain of the sugar that we add to tea or eat in the form of powdered sugar.

There is also brown cane sugar, which differs from regular white sugar in the presence of molasses. But essentially there is not much difference between them.

2. Rinse your mouth often.

Brushing your teeth is often no less harmful than consuming too much sweets, and washing off excess sugar with water is absolutely safe for tooth enamel.

3. Move.

The effect of activity on the body is positive. Any excess calories, whether they are stored in the form of sugars or in the form of fats, will be spent in this case not on the formation of folds on the sides and buttocks, but on muscle activity and the activation of all processes in the body. After all, we remember that movement is life, health and happiness.

And after a tiring run, eating or drinking a cup of sweet tea will be a real necessity, for which your body will thank you.

Modern statistics confirm the fact that annual sugar consumption is increasing.

Each person accounts for up to 60 kg of this product per year. Today it is one of the common products included in the usual daily food. No one denies the need for its presence in the diet. But whether it brings benefit or harm to a person directly depends on the amount of its consumption.

Sugar: its composition, calorie content, types

Sugar - sucrose plant origin, V pure form– a carbohydrate that consists of glucose and fructose.

Its name “sarkara” means “sand” and comes from Sanskrit. This means that the product was known to man in ancient times.

Depending on the raw materials from which sugar was made, there are varieties:

Reed;

Palm;

Maple;

Beet;

Sorghum.

All types of sugar are produced:

unrefined (has Brown color);

Refined ( white).

Refining - process complete cleaning product from the presence of molasses, molasses, mineral salts, vitamins, gummy substances. The result of processing is the production of white sugar particles.

Refined and unrefined varieties have differences in composition. White sugar consists almost entirely of carbohydrates, while brown sugar additionally contains impurities. The list of these impurities and their quantitative volume depend on the quality of the purification and raw materials produced.

Indicators Refined sugar Unrefined sugar

Calorie content, kcal 399 396

Carbohydrates, gr. 99.6 96

Squirrels, gr. 0 0.67

Fats, gr. 0 1.03

Calcium, mg. 3 22-62.7

Phosphorus, mg. — 4-22.3

Magnesium, mg. — 4-117

Zinc, mg. — 0.6

Sodium, mg. 1 -

Potassium, mg. 3 40-330

Differences in chemical composition between the two types of product are insignificant. The calorie content of sugar and protein content have almost the same values.

A slight difference is observed in the content of proteins and fats (they are completely absent in white sugar).

Sugar: what are the benefits for the body?

Despite the established opinion that sugar is harmful, we should not forget that a small amount of it is simply necessary for a person. Doctors confirmed the fact of the impossibility of existence human body without its complete absence.

The benefit is that moderate amount sugar provides the body with more energy. The glucose it contains can satisfy energy needs body.

Glucose helps form barriers to toxins in the liver and spleen. Due to this beneficial property, patients are prescribed glucose administration to relieve intoxication and many liver diseases. In case of pathology of these organs, a “glucose diet” is prescribed.

Sugar stimulates the production of serotonin. It is also called the “happiness” hormone. The product activates the blood circulation process in the brain. If you refuse it, sclerotic changes will be observed. The product reduces the risk of plaque formation in blood vessels, which reduces the likelihood of blood clots, and sweet lovers are much less likely to suffer from arthritis.

With the right and thoughtful approach to this product, it can be beneficial for the body.

Sugar: what is harmful to health

When consuming sugar large quantities causes significant harm to health:

1. weakening occurs bone tissue. The process of absorption of sugar by the body and its breakdown into carbohydrates is possible only with the help of calcium. With large incoming doses of the product, the required amount of calcium for its processing is taken from the bone tissue. Therefore, those with a “sweet tooth” experience thinning of dental and bone tissues, and the risk of fractures increases.

2. Diseases of teeth and gums appear more often. Sugar negatively affects the acidic environment in the mouth and harms the condition of the enamel on the teeth. Under its influence, it breaks down faster and becomes vulnerable to bacteria and microbes.

3. A rapid increase in body weight occurs due to the deposition of fat under the skin of the abdomen and thighs. Sweets cause a rise in insulin, which promotes the excitation of neurons that are responsible for appetite. Their excitement causes a feeling of false hunger, and the person begins to eat more often.

4. The aging process accelerates. Able to neutralize collagen, which is responsible for the elasticity and firmness of the skin. As a result of its work, the number and depth of wrinkles increases.

5. Neutralization of vitamins. For normal absorption of glucose it is consumed a large number of vitamins of group B. With large amounts of it, vitamin deficiency develops in the body, which leads to an exacerbation of a number of chronic diseases and the development of new diseases.

6. The effect of addiction to sweets develops. Excessive consumption of sweets leads to psychological dependence, with symptoms reminiscent of drugs.

7. Depletion of energy reserves. It seems like a paradox that sugar, being a strong energy carrier, can in large quantities cause a decrease in the synthesis of carbohydrates in the body, and a rise in insulin can cause the development of apathy and depression.

8. Violation of heart activity. The development of cardiac muscle dystrophy is associated with a lack of vitamins in the body.

Many common foods contain sugar. Its content is “off the charts” in soda, baked goods, sauces, homemade jams, compotes and preserves, and desserts. At constant use These products accumulate an impressive “sum” of this carbohydrate and its beneficial properties are reduced to zero.

For pregnant and nursing mothers: the harm of sugar

The danger of sugar for pregnant women and women breastfeeding their babies lies, firstly, in the technology of its production. Crystalline sugar undergoes chemical treatment, after which the amount healthy carbohydrates is reduced to a minimum.

Secondly, the threat of this product lies in the fact that a lot of calcium is spent on its absorption. This element is important for correct formation bone tissue and skeleton of the baby. If calcium is spent on the absorption of glucose, then a double problem will arise: a lack of this element for mother and child.

Thirdly, sugar reduces several times protective properties body, which inevitably leads to the development of a number of diseases and exacerbation of chronic ones.

Fourthly, with excess intake of this product, the process of fat formation intensifies. If future mom does not take measures to stabilize his condition, then there is a risk premature birth.

The harm of sugar is that it is able to consume B vitamins. Its deficiency affects not only the condition of the mother’s body, but also the baby: visual acuity decreases, nervousness and feeling appear. constant fatigue, sleep problems, weak muscle tone, immunity decreases, memory and thinking deteriorate, etc. Such problems will completely disappear if you include the consumption of natural sugars in your diet.

All these consequences must be constantly remembered by mothers who want to see themselves and their children healthy.

Sugar for children: good or bad

Proper nutrition is considered the key to a child’s health. Today in stores there is a wide variety of sweets in bright and beautiful packaging. It's hard to resist and not let your baby try candy or cake. Parents don't see anything wrong with this. Moms and dads don’t even imagine what their child’s “sweet” childhood might lead to.

The least that sugar can do is kill your appetite. But in fact, the list of what its excessive use leads to is large:

1. Sweets cause disorders in emotional state and the child's behavior. Headache, frequent change mood, fatigue, sleep disturbance, memory loss – these are the symptoms that are observed in children who frequently consume sugar.

2. Immunity decreases. The risk of developing diseases increases significantly due to decreased immunity. It is not recommended to “indulge” babies with sweets when they are sick, since glucose helps the development of pathogenic microflora.

3. Sugar deprives children of beneficial microorganisms. The concentration of chromium and calcium and B vitamins decreases especially strongly.

4. Teeth and bones are destroyed. Calcium, which is the key healthy teeth and strong bones, is required in large quantities for normal absorption of sugar. Therefore, teeth and bones are the first to suffer.

In addition to these shortcomings, one must take into account the fact that sweets contain preservatives, dyes, flavors, and taste enhancers that do not bring health benefits. Therefore, parents decide on their own whether to give their children sweets or not.

Sugar: harmful for those losing weight

To put your figure in order by proper nutrition It will not be enough to count the number of calories you consume each day.

In the fight against overweight In the first place comes a sharp restriction or refusal of all culinary products and carbonated sweet drinks.

The reason for the restriction is the presence of sugar in them, a product that greatly affects:

Exchange processes;

The functioning of the digestive organs;

The process of fat formation;

Develops addiction to sweets;

Causes a false feeling of hunger, forcing you to eat more often.

The product has a high calorie content (100 grams contains almost 400 kcal) and is completely contraindicated by nutritionists.

Those who are trying to put their body in order should not forget that up to 15% total mass in cookies and candy it is sugar, in juices, yogurt and ice cream - up to 10%, and in sweet soda its content reaches 33%. There is no benefit to the body from such sugar content.

For successful weight loss, the number of calories per day should be reduced to 1500, with a norm of 2000 kcal per day. Nutritionists have calculated that a woman can eat no more than 32 grams of sugar per day, a man - 48 grams. This figure also includes the sugar that is in the products. Therefore, it is better for those who are watching their figure to completely avoid using it in its pure form.

Today sugar is included in daily diet It is difficult for every person and most to imagine their life without him. But in order to preserve your health and the health of your loved ones, it is better to completely abandon this product or minimize its use.

When we hear the word “sugar,” many people immediately think of the sweet white powder that we add to coffee. However, table sugar, or sucrose, is only one type of sugar used in food.

Sugars are low molecular weight carbohydrates organic matter, having a similar structure. There are many types of sugars: glucose, fructose, galactose and others. Various sugars are present at least in small quantities in most foods.

Another name for low molecular weight sugars is carbohydrates. This group also includes:

starch (an oligosaccharide found in potatoes, rice and other foods);
alimentary fiber(in whole grains, legumes, vegetables, fruits and berries);
materials like chitin, which makes up the shells of crustaceans, or cellulose, which contains the bark of trees.

In the end complex carbohydrates are broken down in the body into simple ones, and the whole difference between them lies in the complexity and speed of absorption. For example, sucrose, a disaccharide consisting of fructose and glucose, is digested faster than dietary fiber, a mixture of polysaccharides and lignin.

Therefore, if you eat food with high content dietary fiber, it will take longer to digest, your blood glucose levels will slowly rise, and your feeling of fullness will last for a long time.

This is what distinguishes slow sugars, for example, buckwheat, from fast carbohydrates (chocolate). Essentially, they break down into the same monosaccharides, but the low rate of absorption (in addition to fiber and vitamins) makes buckwheat more beneficial.

Why do we love sugar so much?

Sugar molecules contact receptors on your tongue that tell your brain that you're eating something really tasty.

Sugar is perceived by our body as a good product, because it is quickly digested and provides enough calories. In times of famine, this is of decisive importance for survival, so the sweet taste is recognized by the body as something pleasant.

In addition, fruits naturally contain a lot of sugar, which are also full of vitamins, minerals and energy.

However, not all people love sugar equally. Some eat it in small doses - it is enough for them to eat one candy with tea to be satiated. For others, a whole box of sweet donuts isn't enough.

The love for sweets depends on many factors:

depending on age (children love sweets more and try to avoid bitter foods);
from eating habits learned in childhood;
from genetic characteristics.

Is sugar to blame for weight gain?

It seems that with sugar everything is simple: the more sugar you eat, the more fat you get. In reality, everything is much more complicated. There are recent studies that show that sugar is not the root of all ills.

Study 1. Effect of carbohydrates, sugar and insulin on weight

In the study Calorie for Calorie, Dietary Fat Restriction Results in More Body Fat Loss than Carbohydrate Restriction in People with Obesity. In 2015, Dr. Kevin Hall tried two diets, low fat and low carb, to see which worked best.

During the study, 19 participants spent two weeks on each diet. The interval between diets was 2–4 weeks of normal nutrition.

Study 2. Sugar while dieting

Another study Metabolic and behavioral effects of a high-sucrose diet during weight loss. showed that if the caloric norm is observed, sugar consumption has no of great importance. The study involved 44 women over 40 years of age.

For six weeks, all participants in the experiment adhered to low calorie diet: Consumed approximately 1,350 kcal per day, 11% of total calories from fat, 19% from protein, and 71% from carbohydrates.

Moreover, half of the subjects consumed large amounts of sucrose (43% of total energy), and the other half only 4%.

As a result, women from both groups experienced weight loss, decreased blood pressure, in the body and fats in plasma. Small differences between groups were found only in cholesterol and low-density lipoprotein levels.

This study also proves that as long as you eat enough calories, the amount of sugar does not affect your weight gain or body fat percentage.

There is another study Effect of eucaloric high- and low-sucrose diets with identical macronutrient profile on insulin resistance and vascular risk: a randomized controlled trial., which proves that sucrose does not affect weight gain. In it, two diets were identical in terms of calories and macronutrients, but in one sugar made up 25% of total calories, and in the other - 10%. As a result, participants from both groups did not change in weight, glycemic profile, or vascular health.

Based on research data, a certain conclusion can be drawn.

Sugar does not contribute to fat storage unless you exceed the limit daily calories and don't reduce required amount squirrel.

However, sugar can still cause obesity, but not directly, but indirectly.

How sugar makes us fat

The negative effect of sugar on weight is explained by the fact that sweet foods are very high in calories. By consuming more sugary foods, you risk greatly exceeding your calorie allowance, which leads to weight gain.

At the same time, as we said above, our body loves sweet foods and is capable of consuming them in large quantities. Such food is quickly and easily digested, stimulates the pleasure center in the brain and makes you feel...

It is this aspect, and not sugar itself, that makes sweets such a dangerous product for health.

Does sugar increase the risk of developing type 2 diabetes?

In type 2 diabetes, the body develops insulin resistance and poor glucose control. The hormone insulin can no longer do its job of transporting glucose into the body's cells, so blood glucose levels rise.

This disease is also related to how much fat we accumulate in the liver or around other organs such as the heart or kidneys. And since overconsumption Fast carbohydrates increase the accumulation of fat in the body; sugar actually increases the risk of type 2 diabetes.

However greatest influence The overall percentage of body fat and the amount of physical activity influence the occurrence of diabetes.

So a recent meta-analysis Importance of weight management in type 2 diabetes: review with meta-analysis of clinical studies. showed that 60–90% of all types of diabetes are associated with overweight, and not at all with the amount of sugar consumed. AND the main objective Diabetes treatment is weight loss, not sugar reduction.

This is due to the fact that fat in the body is not just energy reserves for the future, but biologically active tissue that produces hormones. If we have too much fat, it can disrupt metabolic balance, including how the body regulates blood sugar.

In most studies, scientists consider the main causes of diabetes to be:

increase in body fat percentage;
insufficient physical activity;
genetic predisposition.

Controlling your sugar intake is only a small part of preventing type 2 diabetes. It is more important to control the amount of fat in the body and physical activity.

Does sugar affect the occurrence of cardiovascular diseases?

As is the case with type 2 diabetes, sugar indirectly increases the risk cardiovascular diseases. The high calorie content of sugar increases the possibility of weight gain, and fat, as a biologically active tissue, increases the risk of heart disease.

In addition, as the study above showed, a diet high in sucrose increases cholesterol and low-density lipoprotein levels, which also negatively affects vascular health.

However, the occurrence of cardiovascular diseases is influenced by many various factors: Availability bad habits, lifestyle, ecology, stress level, physical activity, amount of sleep, consumption of vegetables and fruits.

The amount of sugar you consume certainly affects your heart and vascular health, but considering all the other factors listed above, it's only a small piece of the puzzle.

How much sugar can you eat without harming your health?

In the manual Guide to Sugar Intake for Adults and Children. by sugar consumption World organization Health officials are calling for a reduction in refined sugar intake to 10% of total calories. That is, if you consume 2,000 kcal per day, then 200 of them can be obtained from sugar. This is approximately 50 g or ten teaspoons.

However, WHO notes that by reducing your sugar intake to 5% (25g or five teaspoons) per day, you will reduce your risk of developing obesity and.

It should be noted here that the figures refer only to refined sugar, so you can eat sweet fruits without fear of breaking the rules.

conclusions

It cannot be argued that sugar is a healthy substance, because it is not. It does not contain vitamins and minerals, antioxidants, water or dietary fiber. Eating a lot of sugar won't make you stronger or healthier - it has no protein or unsaturated fats. fatty acids.

But you shouldn’t demonize it by blaming all your health problems on sugar.

Health, like illness, is built from many factors, and sugar itself cannot be the cause of obesity and development dangerous diseases.

Maintain your calorie intake, eat enough protein, fruits and vegetables - and a few spoons of sugar or a sweet donut will not harm your health and figure.

He was demonized and called the cause of the obesity epidemic. But is sugar really bad for your health? Are all sugars the same? That's what the science says.

If sugar is bad and “toxic”, then what should we think about fruit?

This is a hypothetical question that is rarely answered - or even considered - by those considering a "sugar-free" diet.

Before you give in to the simple idea that sugar is the root of all evil, consider a similar scenario. Just yesterday, fats were harmful and it was necessary to exclude them from the diet. Today, they are on their way to being vindicated - some of them are not as harmful as thought, while others are beneficial to health.

But in the minds of many people, an “obvious” enemy has appeared: carbohydrates, or, to be even more precise, sugar.

Still, the question remains whether consuming sugar is “bad for you” regardless of dosage, or is it – as with everything else – a matter of how much of it you consume and where it comes from? If you dig deeper into the science, you'll find that if you want to lose weight, live longer, and feel great every day, you don't have to give up sugar completely.

Sugar is so much more than just white matter, which you put in your coffee. (This is sucrose.)

In biochemistry, sugar is either a monosaccharide or a disaccharide (“saccharides” is another name for “carbohydrates”).

Monosaccharide - simple sugar
Disaccharide – a sugar consisting of two monosaccharides
Oligosaccharide contains from 2 to 10 simple sugars
A polysaccharide consists of two or more simple sugars (300 to 1000 glucose molecules in starch)

In short, all carbohydrates contain single sugars. If we go back to the example of sucrose, or table sugar, which is actually a disaccharide of the simple sugars glucose and fructose.

Meanwhile, starch, dietary fiber, and cellulose are polysaccharides. And let's face it: fiber—which most people know as a good thing—is also a form of sugar.

Of the above three things, we can only digest starch, which is made up of glucose. You've probably heard the name "complex carbohydrates" or " slow carbohydrates", starch is one of these. They are called slow because it takes time for the body to break them down into individual sugars (particularly glucose, our “blood sugar”).

Therefore, the idea of a completely “sugar-free” diet means giving up a lot of completely healthy foods. Of course, you can live without eating sugar or even carbohydrates... but only because your body is able to synthesize the glucose it needs from fatty acids and amino acids.

This happens because your body needs sugar. Glucose is needed as fuel for such important functions as an activity nervous system or brain. (Yes, your brain functions not only on glucose, but it needs it; it also helps cells communicate.)

More importantly, there are many perfectly healthy foods that contain sugar (see below). Any "no sugar" diet that requires you to give up all of these foods isn't foolproof, right? And this is the point: any extreme approach is often wrong, including the generalized statement “don’t eat any sugar.”

Originally Answered: Is sugar bad for you?

As with most things in life, harm depends on the norm.

As mentioned, your body does need sugars, so much so that it will produce some of them itself even if you eliminate all carbohydrates from your diet.

But consuming too much sugar leads to type II diabetes and obesity (although overeating will make you fat even if you don't eat a lot of carbohydrates). Excess sugar also leads to an increase in the amount of advanced glycation end products, and as a result, skin damage and more high risk development of cancer and cardiovascular diseases.

This is why added sugar can be dangerous, not because it is “addictive like cocaine” (it can be addictive, but not as addictive as cocaine or food addiction). The real danger of sugar is not that it makes you gain weight. There are still only 4 calories in 1 gram of sugar. And 4 calories won't make you fat. However, it is possible to swallow a ton of sugar and not feel full. And you eat a little... and then a little more... and then some more... and then you realize that the box of cookies is empty, but the hunger has not gone away.

It's too easy to overdo it with added sugars. This statement is true for each of them, no matter how healthy the name sounds. For example, “cane sugar” is especially healthier than other sources of sucrose, despite the fact that it is natural. In contrast, the unfortunate high fructose corn syrup (usually 55% fructose and 45% glucose) is not much worse than sucrose (50% fructose, 50% glucose).

Sugars are especially insidious in liquid form. You can drink and drink and drink them in huge quantities, comparable in calories to a 5-course meal, and stay hungry. Perhaps it's not surprising that soft drinks linked to the current obesity epidemic. Today, soda and cola make up 34.4% of the total amount of added sugar consumed by adults and children in the United States and are the main source of added sugar in the average American's diet.

In this regard, fruit juices are no longer healthy option. In fact, they may be even worse. Why? Because the sugar contained in fruit juice is fructose, which can put a strain on the liver (only the liver is capable of processing fructose in any large quantities). Current evidence also indicates that consuming fructose results in greater weight gain than glucose.

But this statement is not true for sugars found in vegetables and fruits. In fact, it is necessary to make it clear that today:

THERE IS NO EVIDENCE THAT EATING FRUIT, EVEN IN LARGE QUANTITIES, WILL DAMAGE YOUR HEALTH.

Unlike fruit juices, whole fruits satisfy your hunger. Apples, although hard, are 10% sugar... and 85% water; That's why it's hard to eat too many of them. Additionally, recent research suggests that fruits may help regulate blood sugar levels.

There is one "sugar" drink that doesn't pose a similar threat: milk. While milk contains sugar (lactose, the disaccharide of glucose and galactose), its content is much less than that of fruit juice In addition, milk also contains protein and fat. During a period when fats were considered the enemy, skimmed milk was considered healthier than whole, but today this is not the case. Now that fats are (partially) justified, whole milk, backed by a wealth of evidence, has returned to fashion.

So how much sugar can you eat per day?

We have something to celebrate: You don't have to feel guilty every time you eat added sugar. But you should stay aware of your consumption and do your best to not exceed the following indicators:

100 calories per day for women (about 6 teaspoons, or 25 grams)
150 calories per day for men (about 9 teaspoons, or 36 grams)

What does it mean? Aim for 1 whole Snickers or about 7-8 Oreo cookies. But please note that we are not saying that you should add Snickers or Oreos to your daily diet. These examples simply show the total amount per day that you might want to limit yourself to. But remember: added sugar is hiding in many unexpected places, like soup and pizza.

While average level While sugar consumption in the US may be declining (it was around 400 kcal/day in 1999-2000 and fell to 300 kcal/day in 2007-2009), it is still too high. And of course, that's an average, and averages lie. Some people consume much less sugar, while others... much more.

But let's say you don't like the same numbers for everyone. And you don't want to carry around a whole set of measurements all day or worry about how many grams of sugar you've eaten. If so, here's an even easier way to keep your intake under control. It is based on the old Food Guide Pyramid, which was introduced in 1992 and replaced in 2005 by MyPyramid, which was eventually replaced by the scheme that the US government still uses today.

The basis of a healthy sugar pyramid is vegetables and fruits: they are not only filling, but also provide the body with fiber, vitamins, minerals and phytochemicals (bioactive compounds found in plants, some of which are beneficial to our health), in addition to sugar. You can also include whole milk here. The small amount of naturally occurring sugar found in bread is also not considered added, but sugar that is often added during manufacturing in the United States is.

Granulated sugar, like salt, is an integral component of the daily diet. Many people don’t even think about how much sweet substance they consume per day. IN last years the popularity of proper nutrition is increasingly forcing supporters healthy image life to ask the question: what is the calorie content of sugar?

White carbohydrate serves the most important source energy for the brain and body, so it is important to understand its composition and rules of use.

Composition and nutritional value

People learned to produce white crystalline powder in the mid-19th century in the Czech Republic. Granulated sugar is extracted from special varieties of cane or beets.

If we talk about sugar as an organic compound, then it is fast carbohydrate. Once in the body, the product breaks down into glucose and fructose, which serve as food for brain cells. The amount of sugar directly affects the supply of energy necessary for full human life.

Many other health indicators directly depend on monosaccharides. Insulin, essential for metabolic processes pancreas, produced under the influence of saccharides. Another hormone serotonin, a neurotransmitter that shapes mood. Its amount is regulated by the consumption of the sweet substance.

Sugar is necessary for children and adolescents during the period of active development. In infants, it ensures the full growth of cells and muscles, in schoolchildren - the development of memory and thinking.

Sweet carbohydrates enter the body not only as an additive to tea or baked goods. The substance is found in fruits, vegetables, cereals and drinks.

Despite the fact that both adults and children need sugar for the healthy functioning of internal organs, it is overuse could be dangerous. Men and women over 40 should limit the amount of sweets they eat. In addition, there are many restrictions for people with chronic diseases.

Types of sugar

Talking about sugar, usually, they mean white powder from sweet varieties of sugar beets. However familiar product has several classifications according to type of origin.

Depending on the feedstock, the following types are distinguished:

Reed. It is made from the sap of a plant that looks like bamboo. Sugarcane loves warm climates and was originally grown in India. It was first used as a base for a sweet food additive long before people learned to process beets. There are two types of cane sugar: white refined and brown unrefined;

Beetroot- produced by evaporating vegetable juice. During the processing, a yellow crystalline powder is released, which is purified and used in cooking;

Maple, otherwise known as maple syrup. Made from maple tree sap. Most of the world's production of this product occurs in Canada, where it is widely distributed;

Sorghum. Environmentally friendly, but quite rare species. It is extracted from the juice of the sorghum plant, which is mined in India and China. Sorghum sugar is typically produced as a brown syrup;

Palm, made from coconut palm wood. Most common in regions where the tropical plant grows.

Based on their structure, sugar is divided into two large categories: sand And refined sugar . The latter is pressed cubes of purified product. This format is convenient to take with you on trips and add to tea.

Refined sugar can be classified into the following types:

pressed crushed;
pressed with additives;
refined powder.

Depending on the size of crushing, refined sugar is produced in small portioned boxes or packaged in bags.

Regular sugar can come in the form of lump, crushed, candy, or bulk sugar.

Benefits and harms

Useful properties of sugar:

One of the determining factors in the usefulness of a product is its calorie content. Granulated sugar, which consists of 99% carbohydrates, has a bunch of useful properties , despite the high kcal indicator.

The value of the product lies in the following positive actions:

It has been scientifically proven that sugar is necessary for proper blood circulation; it ensures the functioning of the brain and spinal cord;
sweet carbohydrates prevent the formation of blood clots, that is, they reduce the risk of vascular plaques;
people who regularly eat sugar reduce the likelihood of joint damage;
glucose in the product neutralizes toxic substances, thereby helping to perform liver functions. Patients with liver and spleen failure are often prescribed a diet high in saccharides.

The chemical composition of sugar does not contain vitamins; its formula implies the presence of two monosaccharide components: glucose and fructose. These are the elements that are used internal organs to maintain normal blood circulation, brain and liver cell function.

With moderate sugar consumption, its harm to the body is minimal. For an adult, the norm of white sand is about 30 grams per day. In this case, it is worth considering not only the amount of carbohydrate consumed in its pure form, but also those saccharides that are included in food products.

Harmful properties of sugar:

Excessive use of sugar is fraught with the development of dangerous diseases of cardio-vascular system. Other negative consequences:

To assimilate carbohydrates, the body spends calcium reserves necessary to strengthen bone tissue. As we age, bones can become brittle and brittle;
glucose contributes to the destruction of tooth enamel and also creates favorable conditions for the proliferation of bacteria in the oral cavity;
risk of obesity. In the liver, sugar is deposited in the form of glycogen, a substance that controls fat stores. High rate glycogen serves as a signal to the body about the need to store fat in the abdomen and thighs;
uncontrollable feeling of hunger. As a result of sugar abuse, a malfunction occurs in the neural reactions of the brain. A person loses control over appetite, false hunger arises. As a result: a jump in insulin and overeating;
premature old age. It has been proven that sweets have a negative effect on the condition skin. Upper layer the epidermis loses its shine and elasticity, wrinkles appear;
