Vitamin puree cocktails that fit into the vicious diet as an excellent source of vitamins, are not as harmless as we would like. So, at least, according to US researchers
True, it is necessary to make a reservation – it is primarily about Industrial cocktails, which are very popular in many countries. Usually smoothies sold in bottles of various sizes, along with fruit and vegetable juices. In this regard, a study was conducted, says the publication The Daily Mail, with reference to the BBC
One of the advantages of smoothies is their ability to raise the level of antioxidants in the body. This specific substances that help cleanse the body of accumulated toxins, toxins, as well as some harmful molecules of cells that attack cells in the body called free radicals.
Free radicals are formed in our body as a result of natural processes – the burning of glucose, the result of the functioning of enzymes that break down the food coming, and others. Antioxidants are designed to purify the cells from harmful free radicals, as it turns out, are produced in our body, and it is an amount that is necessary at this point. This phenomenon refers to the phenomenon of homeostasis – the balance of the components of a living organism, which does not tolerate outside interference.

The consumption of smoothies, as well as fruit juices in large quantities, the researchers believe violates the natural process of developing its own antioxidants, thus provoking an increase in the number of free radicals. Scientists conducted an experiment, which was attended by 10 volunteers, who were asked to drink 360 ml of the ready smoothie (standard volume of bottles, which are sold in supermarkets). According to the analysis of the blood of participants of the experiment it was found that antioxidant levels significantly changed during the day – immediately after drinking a smoothie he grew up at times, but after 4-5 hours sharply decreased significantly lower than normal, thus allowing to roam free radicals. The amount of antioxidants in the blood of the subjects approached to normal only by the end of the experiment – after almost 24 hours after ingestion of drink.

One of the participants in the study Dr. Brandt explained the results as follows: “We are constantly produce their own antioxidants in the right amount – the balance is constantly maintained by our body is called homeostasis. Thus, organs interact maintain the required level of sugar, temperature, and other conditions. Once the substance, particularly antioxidants, are beginning to enter from the outside in large numbers, production is suspended or even terminated and recovered long enough. ”
Another side effect of smoothies, as well as fruit juices, scientists have named an excessive amount of sugar that comes with them due to the high concentration in fruit drinks. Natural fruit much healthier and have virtually no contraindications – all a matter of quantity.

Nevertheless, Dr. Brandt warns against demonizing the free radicals, arguing that they perform an important role in homeostasis and included: “Free radicals are necessary, however, despite how much. They perform signaling functions by sending pulses to the brain, indicating that the cells require repair and recovery ”
So the main message to the scientists – know the measure, use common sense and do not interfere with your body work. A smoothie – not at all bad, the main thing is not to overdo it.
