Are you ready for exams? Avoid the fructose-sweetened beverages and sweets. This sugar slows down thinking and hinders learning!
Previous scientific studies have proven that fructose increases the risk of diabetes, obesity and fatty liver. Now scientists are putting fructose in one more disruptive effect on disrupting normal brain function. Their research was published in the Journal of Physiology.
The average American eats 56 kg of sugar annually, including nearly 16 kg of glucose-fructose syrup. In the 19th century, Americans consumed an average of 1 kg of sugar per year. In Poland, glucose-fructose syrup is slightly less widespread, although insightful reading of labels on packaging of sweets shows that it is gaining more and more popularity in us. The over-consumption of sugar will be associated with the risk of diabetes, obesity and even cancer.
Fructose contained in fruits does not have such a destructive effect on health, because it is accompanied by substances acting like an antioxidant antioxidant, fiber. The most harmful is fructose used for sweetening and preserving food products (bars, drinks, biscuits).
Studies that have demonstrated the destructive effects of fructose on the brain have been carried out on rats. In fructose-fed animals, there was a decrease in the activity of brain synapses (connections between nerve cells), which on the outside revealed a much slower conquest of the previously learned labyrinth. They also showed symptoms of reduced body response to insulin. Researchers suspect that this could be the main cause of deterioration in brain function, because insulin affects the ability of nerve cells to use sugar. A sweet diet causes the body to produce more insulin, which in turn may result in a decrease in cell sensitivity to its effects.
Rats who ate a diet rich in fructose, but at the same time their food contained omega-3 and DHA from linseed, had no such problems to overcome the labyrinth faced by animals that were not given linseed.
Conclusions. A diet rich in fructose worsens the ability to learn and remember. This effect may limit the increase in the amount of omega-3 fatty acids in the diet.
Are you hurting your research on rats and you do not really believe that their results can make a difference to humans? Think again, because rats and people have up to 90% of common genes …
