Sugar consumption affects the brain in the same way as stress
For a long time, scientists have warned about the dangers of excessive consumption of sweets. The sugar habit can not only cause diabetes and obesity, but it can also trigger heart problems, cancer, and more.
Australian scientists have established that there is a direct link between sugar consumption and brain dysfunction. In the experiment, newborn mice were divided into two groups. Mice from the first group were raised under stress conditions, while mice from the second group were raised under normal conditions. Half of those who grew up in a nervous environment ate regular food and drink, and the rest ate sugar-rich foods. The same model was used to feed mice that were growing in a normal environment.
Experiments showed that mice that were fed sweets and were not stressed had a hippocampus similar to the hippocampus of mice that grew under stress. What's more, the researchers found high levels of cortisol, a stress hormone, in the brains of these mice. The hippocampus was most severely affected in stress-plus-sugar mice; the mice showed the highest cortisol levels. Mice that were raised in a non-stressful environment and received normal food had the healthiest brains with normal cortisol levels.
Excessive amounts of the stress hormone are known to affect the brain and heart. In addition, high cortisol levels kill neurons, damage memory and impair cognitive (mental) ability.
In conclusion, I would like to point out that children who consume too much candy at an early age may have problems with cognitive abilities during adulthood.

Watch the documentary "That's sugar film", very very interesting, you won't get bored. I even looked at the cinema and did not regret it. Lots of useful information and easy presentation.
Sugar, as well as honey, flour products, cereals and others like them, contain easily digestible carbohydrates. What does digestible mean? The fact is that they are easily soluble in water and are quickly absorbed from the intestines into the blood. This, in turn, makes the insular apparatus of the pancreas work actively. Right off the bat, as they say. And a lot of sugar is a lot of insulin. And yes, such a depleting diet eventually leads to the development of type 2 diabetes. But I want to draw your attention once again that the reason for its development is not sugar consumption, but overeating in general. After all, it is sugar not from sugar (glucose + fructose), but from sugars (low molecular weight carbohydrates).
But diabetes in this list is the first one completely undeserved. Have you seen at least one diabetic (with type 2) without excess weight? That's it.
The fact is that sugar has a small satiating ability, but it significantly increases the calorie content of food. Hunger is satisfied less, food is consumed in large quantities, and even what kind of food. Overweight and obesity suggest themselves. In addition, sugar leads to the production of dopamine in the brain. And the problem is that it produces more dopamine than any abstract healthy food. In other words, it is addictive. Plus, sugar, donuts, buns are foods with a high glycemic index, that is, with the constant intake of such foods, a person has an increased level of insulin in the blood for a long time. In order to reduce hyperinsulinemia, more and more food is constantly needed. And this, again, is overweight. And that's just here it would be worth mentioning diabetes, but, fortunately, we are done with it.
I'd rather say a little about insulin, but on the other hand. It is known to regulate cell growth and division. And uncontrolled cell growth and division is oncopathology. Therefore, it is possible that hyperinsulinemia is somehow involved in the development of neoplasms.
In addition, sugar is very bad for dental health, since it provides bacteria in the oral cavity with easily digestible energy. Everyone has probably heard about caries from sweets since childhood.
One could also say about the increased risk of cardiovascular pathology due to an increase in the level of low and very low density lipoproteins, but I do not understand this too much and I can't explain it convincingly.
Well, diabetes is not the worst thing. The likelihood of getting cancer increases, because cancer cells are very fond of sugar and feed on it. ----
Diabetes. It seems that there is no more obvious answer. I don't even know what else to add here. There may still be obesity, but diabetes is more likely.
