About the benefits or harm of fruit juice lately a lot of arguing. Mostly he is accused in the fact that it increases the level of blood sugar. That is, in varying degrees, affects the risk of developing diabetes of the second type, which binds with obesity.
Long been known that fruit juices contain large amounts of vitamins, minerals, soluble dietary fibers, carotenoids, flavonoids, and other useful and necessary body substances. But still, there are experts who believe that drinking large quantities is dangerous: because juices high glycemic index, therefore they can cause a jump in the level of glucose in the blood. Until now, this assumption was quite tenacious. Now he tried to refute on a scientific basis.
The aim of the researches of the American scientists were to study, does drinking fruit juice on insulin sensitivity and glucose levels fasting blood (these data are considered most reliable).
The Americans analyzed data from a total of 18 different studies that were conducted in different parts of Europe (Spain, France, Denmark and the UK), Asia (China and Iran) and North America (USA and Mexico). These studies involved both men and women of different ages, with different body mass index (including overweight and obesity) and different condition.
In the process of each study, the subjects daily drank one kind of fruit juice: grape, pomegranate, tangerine, grapefruit, orange, Apple, cranberry. The duration of the study ranged from one to six months. The results stunned many. As it turned out, the use of 100% fruit juice has no significant effect on the level of blood glucose and insulin fasting. In addition, the researchers concluded that consumption of fruit juice also had no effect on insulin resistance. It is worth to point that in the group drinking pomegranate juice, insulin resistance was significantly lower than in the control group.
As a result, scientists came to the unequivocal conclusion: if you drink fruit juice on a daily basis, even glass and more, the risk of developing diabetes does not increase. Why? Because each juice has a unique bioactive substances, which positively influence the level of blood glucose and insulin resistance. For example, pomegranate juice is a source of such indispensable substances as ellagitannin and punicalagin.
In orange, tangerine, grapefruit juices dominate other useful flavonoids: naringin, hesperidin and so Cranberry juice is a source of valuable polyphenols, including procyanidins, anthocyanins, quercetin and myricitrin. Grape juice is tianidine and glucosides of delphinidin and Apple juice – an excellent source of quercetin.
So those who every day used to drink juices, be wary of diabetes is just not worth it — so said the scientists.
