According to recent research, high amounts of sugars are harmful not only to health but also to the ability to learn and memory. Let’s see together what the experts have discovered.
New alert for gourmands and for those who follow ahigh-calorie diet: not only extra pounds, high blood glucose levels would compromise the cognitive and memorization abilities of the brain, also counteracting the development of stem cells involved in building new nerve circuits.
Damages confirmed by an Italian study, just published in Cell Report, also useful for clarifying the processes that accelerate moles diabetics lpremature aging and the increased incidence of Alzheimer’s.
High doses of sugar are harmful to health
For the research, the team of scientists of theCatholic University of Rome analyzed the effects caused by high doses of sugar on some neural stem cells grown in test tubes. In addition to being responsible for the repair of brain damage, this particular cell group is used to regulate the correct functioning of the processes of learning e memory.

The experiment demonstrated how the glucose born compromise the operation also reducing its ability to multiply.
“In essence, an excess of sugar burns the cell reserves that the brain needs to make new neurons,” he said Giovanbattista Pani, researcher at the UCSC Institute of Pathology and co-author of the study -. So we fear that those who consume too much sugar will have less cellular regeneration with a consequent negative impact on their cognitive performance “.
In the last phase of the experiment, the researchers switched to in vivo analyzes on laboratory mice to which they administered one low-calorie daily diet, comparable to our 1,500 calories, “which confirmed the results obtained in the test tube”, with an increase in the number of neural stem cells which thus demonstrated their ability to renew themselves.
