Scientists disagree: some say that sugary drinks are the cause of terrible diseases, others believe that they help to lose weight.
Scientists from the Israeli University Ben-Gurion University conducted a study and found that the work of the organs with each time getting worse, if for a long time to consume drinks that contain sugar substitutes. In their study, published on the website Science Alert, they noted that long-term consumption of soda can cause cancer.
The researchers collected data on 210 thousands of components of the soda and determined that most of these substances, such as phosphates, can provoke disturbance of the intestinal microflora. Scientists have discovered that the particularities of the sweetener, which can disrupt the balance of intestinal microflora or completely to kill her.
Tests conducted on mice have shown that artificial sweeteners change the body, the intake of fats and other nutrients in it. Regular saturation of the organism with such substances in large quantities, as shown by the findings of scientists, leads to the destruction of muscle tissue.
Time bomb
At the end of December last year, the European Association of obesity released a report in which has told about scale, which is applied to the body soda. In the document, based on 30 studies from 2013 to 2015, manufacturers of soda is recommended to reduce the percentage of the so-called empty calories in drinks.
As scientists found out that regular consumption of soda causes severe and in most cases incurable form of obesity. They are, as they say in the study, affect the vital organs of the body, and create conditions for the development of serious diseases of the gastrointestinal tract and heart disease. There is even a risk of extravascular fluid accumulation, which is the cause of cardiac arrest.
Blame the sugar
Scientists from South Africa came to the conclusion that the frequent consumption of carbonated drinks increases the risk of diabetes, high blood pressure and stroke. The reason for that is the large amount of sugar. For example, one Bank contains about 39 grams of sugar, and 14 grams more than the usual norm of an adult.
In addition to this, soda contributes to the emergence of excess weight, which leads to metabolic syndrome. According to the study, which had scientists, those who consumed carbonated drinks often complained of the occurrence of cardiovascular disease, and aggravate all this passive lifestyle, Smoking and poor diet.
Senile dementia
Scientists from Boston University in U.S. the results of his study concluded that consumption of sweetened beverages leads to a decrease in volume of the brain. In particular, it suffers from the hippocampus, the part of it that is responsible for the formation of long-term memory. In addition, as it became known, consumers are also susceptible to strokes and dementia.
The experts conducted two studies. In the first, they examined data on MRI and tests on mental ability and memory 4000 residents of the United States. It was found that those who consumed more than two packages of sugary drinks a day had early signs of brain aging. With age, the brain can shrink in volume, but aeration fans this process began earlier.
In the second paper, scientists began studying the relationship between the risk of stroke or dementia and the use of soda. To do this, they took the data on 2888 victims of stroke are older than 45 years and 1484 patients older than 60 with senile dementia. The results were unexpected. The connection between the two problems and the soda was missing, but for those who often ate “diet” soda (in place of sugar in it sweeteners), three times more often peers had strokes and developed dementia.
Destroys teeth
Also concerns scientists as carbonated water is its effect on the teeth because the enamel is exposed to acid. A study by Italian scientists has shown that soda slightly damage the enamel than regular water. As it turned out, a negative effect on teeth has not gas, and the content of sugar in the drink.
It is the combination of sugar and gas is a cause of damage to dental tissues.
Reduces mortality?
However, despite the various statements of the scientists of all countries, oncologists from Yale University conducted a study and found that active drinking diet soda reduces the risk of mortality.
As their study shows, these drinks reduce the mortality from recurrence of rectal cancer. To reach this conclusion, researchers conducted an experiment. It lasted for seven years, involving a thousand patients who have undergone chemotherapy for the treatment of severe adenocarcinoma of the rectum (rectal cancer).
Oncologists found that patients who took at least 350 ml of sweet diet drinks reduced the risk of sudden death from recurrence by 46%. Thus, they showed that the transition from ordinary fizzy drinks to diet reduces mortality of these patients 23%.
Not all sweet improves mood
American scientists conducted a study and came to the conclusion that soft drinks the human body depressed.
The researchers conducted an experiment in which took part more than 260 volunteers. As it turned out, apathy and depression cause four or more glasses of sugary pop a day. Also, scientists have revealed the fact that diet soda causes more severe symptoms of depression.
While scientists have not been able to determine exactly how the drink affects the nervous system, but they noted that abandoning fizzy drinks in favour of natural coffee allows you to beat depression and apathy in no time.
In reasonable quantities it is possible
To a surprising conclusion was made by Russian scientists. So, Professor, Russian national research medical University named after Pirogov, expert Academy soft drinks Sergey Bel’mer during a speech at the forum “Saint Petersburg — Gastro 2015,” said that soft drinks have no adverse effects on the healthy human stomach at a reasonable consumption.
He noted that the carbon dioxide in the drinks are ingested and therefore are harmless to humans, as part of carbon dioxide escapes from the beverage when opening the bottle, the other is diluted with the air swallowing, and the remaining small fraction of the gas, which still reaches the stomach, is rapidly absorbed through the walls of the gastrointestinal tract.
That’s why people are not having problems with the digestive system, moderate consumption of soda can not be afraid for the health of the gastric mucosa.
Will help to lose weight
Studies of American scientists showed that there is a certain benefit in consumption of sparkling water.
So, it helps to improve the swallowing movements by stimulation of the nerves responsible for the swallowing function. But if the mineral water is cold, the effect becomes more pronounced. Also soda is able to extend satiety — use of carbonated water slows down the digestion of food that is definitely beneficial for weight loss.
Another discovery is the fact that soda helps to eliminate constipation. In the two-week study of 40 participants of advanced age, suffering from regular constipation, compared the effect of soda and normal water on the intestinal peristalsis. The control group showed a reduction of symptoms by 58%.
