Negative Impact on Memory and Learning
Sugar and various salted products have a negative impact on cognitive brain function. Long-term consumption of some types of sugar can even result in neurological problems and worsening the ability of memory and learning. That's why scientists advise as little sugar, corn syrup, and other high-glucose products as possible.
Previous studies have been studying a positive effect of glucose on brain function, such as short-term memory enhancement, but other types of sugar such as fructose and sucrose may have a negative effect.
Scientists in a smaller study at New Zealand's Otago University have explored to what extent ordinary table sugar from the household affects the cognitive ability of 49 people. They studied the influence of other types of sugar and compared their effect on cognitive ability with the effect of a placebo sweetener such as sucralose. Experiment participants responded to three groups of questions, including arithmetic tasks.
The study showed that those participants who consumed foods rich in glucose (sucrose sugar) and sucrose had poorer results before testing, compared to those who consumed fructose or sucralose.
Mei Peng, a co-author of study and lecturer at the Department of Food Science at the University of Otago, said she was "fascinated by the discovery of how much sugar consumption can affect the behavior of an individual on a daily basis."
"Particularly interesting is how much sugar consumption can affect the cognitive abilities of an individual. Our study has shown that the "sugar coma" associated with glucose consumption is a very real phenomenon that shows that the level of attention falls fairly after consuming glucose-containing sugars, "he concluded. She also reminded that due to the sugar, which producers put into the ready and half the food, the average person eats about 12 teaspoons of sugar every day.
Earlier studies have shown that continued high levels of blood sugar can lead to aging of the brain or dementia. Scientists have scanned a brain during a previous study by 249 people aged 60 to 64 whose blood sugar levels were within normal limits. For those whose blood sugar levels were higher, four years later, there were more prospects for developing hippocampus and amygdala problems, brain regions associated with memory and cognitive functions.
It was well known that in type 2 diabetes, there is a greater chance of developing dementia, probably due to their high blood sugar levels, which is damaging to the blood vessels. Because of this, the brain can stay without enough oxygen and nutrients.
