The brain is one of the most energy-consuming human organs, being rich in nerve cells, which drives it to consume half the energy of sugar in the body in the form of "glucose".
Some research has indicated that high sugar consumption causes addiction and alters brain chemistry. According to the newspaper "Scientific Reports".
Brain chemistry is defined as a delicate system of chemicals that are found in the brain, specifically at the nerve endings, and are called neurotransmitters that are stored in designated nodes or bulges.
"A lot of people complain of an irresistible craving for sweets, because of this habit obesity and diabetes often develop, but until recently there was no scientific evidence of the relationship of sugar to addiction," one of the researchers said.
Danish scientists from Aarhus University conducted a pig experiment and reached the conclusion that sugar worked as a drug, and the results of the study showed a clear effect on their brains.
"There is no doubt that, because of its physiological effects, it is harmful to health, but we have questioned that sugar affects the brain and behavior," said Michael Winterdal, associate professor of clinical medicine.
Within 12 days, seven pigs received two liters of sugar-sweetened water per day, and with the help of magnetic resonance imaging, scientists compared the animal’s brain image before study, at the end of the first day and after the experiment.
And after only 12 days of eating sugar, scientists noticed serious changes in the dopamine and opioid systems in the brain, as the opioid system, chemically related to well-being and pleasure, was activated after the first dose.
In other words, the researchers found that sugar affects the brain in the same way as narcotic drugs, although research was done on animals.
