Among the traditional disputes between scientists about what is useful and what is harmful, another discovery bomb exploded. It turned out that all sugary drinks, including the supposedly he althy fruit juices, increased the risk of death from cardiovascular disease by 2 times in people over the age of 45.

However, the most shocking thing is that candies and sweets do not have a similar effect on he alth, writes "Trud".

The link between sweets and the risk of death

It is an undeniable fact that in recent years more and more scientific data has appeared on the harm of sugar. The greater its use, the more it accumulates in the body in the form of fat. Therefore, the risk of all kinds of chronic diseases - diabetes, cancer, and cardiovascular diseases - also increases.But research that proves a direct link between the intake of sweets and the risk of death has almost never been conducted worldwide. American scientists did this and published their results in March this year

Their experiment, which lasted 6 years, involved more than 18,000 he althy volunteers over the age of 45. The study participants kept diaries where they duly noted all the sweet things they consumed during the day - drinks and products high in sugar, such as sodas, juices, candy, and ready-to-eat snacks. If one of them died, the possible cause of death was clarified, including a heart attack and other cardiovascular disorders. The following became clear: if a person drinks more than 0.7 liters of sugary drinks per day, the risk of dying from ischemic heart disease increases twice compared to taking less than 30 ml. And one more thing - the probability of him dying from another cause increases. A similar effect appeared regardless of whether the tested had harmful habits, whether they ate abundantly, what their level of physical activity was, etc.

Desserts have no influence

And now – attention! A relationship between the increased risk of death and the intake of sweets was not found! Scientists assume that when using sweet drinks, sugar enters the body practically in its pure form, and from buns and sweets - together with fats and proteins, which makes it difficult for it to enter the blood. The pathogenic influence of pure sugar in sweet drinks is due to most fast carbohydrates. After their use, a sharp change in the glycemic index follows, the level of sugar in the blood jumps, and it is not always "extinguished" with insulin. These carbohydrates are converted into fat stores, and today cardiologists call for great attention to be paid to their use. They occupy a leading place in the development of atherosclerosis. However, this does not mean that sweets are good - just that they are less harmful.

Best to eat, not drink

Of course, fruit juices are different, they have an unequal amount of sugar and glycemic index.After using them, however, more glucose enters the body than when eating the fruit from which they are made. From this point of view, tea with sugar is also not recommended, it is better to take it with dried fruits. Juices should also be diluted or even water should be drunk instead. Grape juice is the most harmful in the ranking, and tomato juice is the most "calm". Be sure to check the label for sugar and carbohydrate content. The authors of the study believe that doctors who warn about risk factors for cardiovascular catastrophe should definitely clarify whether their patients are drinking (and not eating) sweets.

Freshes - unnecessary sugar or a glass of he alth?

The common thing between freshly squeezed juices from different fruits is that they contain concentrated fruit sugar, which, due to the lack of fiber (removed with the pulp during squeezing), is quickly absorbed into the blood and raises insulin.

In other words, the effect on the body of fruit fresh is no different from the effect caused by any other dessert.However, let's make a distinction - it's fine if you consume fresh fruit as an independent meal, mid-morning or afternoon snack and don't eat any other sweets during the day. But if you drink it in addition, then you definitely get more sugar. For maximum absorption of useful substances, it is good to take it as a separate meal, on an empty stomach, at least half an hour before or two hours after another meal. Let's not forget that juice is not water, but food!

The other point of view: no increased risk of diabetes

Recently, the authoritative scientific journal Journal of Nutritional Science published the opposite of the cited results. The Americans analyzed the data from 18 studies conducted in different places of the world: Europe - Spain, France, Denmark and Great Britain, Asia - China and Iran, and North America - USA and Mexico. The participants in the experiment drank one kind of fruit juice every day - from grape, pomegranate, tangerine, grapefruit, orange, apple, blueberry.

It turned out that the consumption of 100% fruit juice on an empty stomach did not significantly affect the level of glucose in the blood. In addition, the scientists came to the conclusion that the use of fruit juice does not significantly affect insulin resistance, which in the drinkers of fresh pomegranate was significantly lower than in the control group. If you drink a glass, or even more, of juice every day, the risk of diabetes does not increase, because there are unique bioactive substances in each drink from a different fruit. Pomegranate juice reduces insulin resistance.
