Sugar often appears in discussions about health as an absolute evil, but in fact it is a vital source of energy for the brain. However, as with many other substances, it all depends on the amount, type and context of use. Psychology today explains how different types of sugar affect the brain and why a stable blood glucose level is critical.
What is food and blood sugar?
Food (diet) sugar is not just the white sugar that we put in tea. It includes molecules such as sucrose, fructose and lactose contained in fruits, dairy products and treated foods. Added sugars, including syrups and concentrates, which significantly increase blood glucose levels.
Glucose is the main "fuel" for the brain. However, its excess in the diet or sharp fluctuations in the blood levels can disrupt the brain.
How does sugar affect the brain?
High glycemic index foods (sweets, sodas, white bread) rapidly increase blood sugar. It can call:
-
insulin resistance that complicates glucose access to the brain;
-
Inflammation in brain tissues is one of the risk factors for depression, stroke and dementia;
-
Oxidative stress due to the formation of final products that damage cells.
The so -called "Western diets", rich in sugars and ultra -treated products, are associated with an increased risk of cognitive disorders and Alzheimer's disease.
Why is stable blood sugar is important?
With age, brain access to glucose becomes less effective. This partially explains the decrease in cognitive functions and the development of neurological diseases. Studies show that type II diabetes increases the risk of dementia by 60%. Even minor insulin disorders can reduce the memory, concentration and speed of thinking.
How to keep the brain in tone?
-
Restrict adding sugars: candy, cookies, carbonated drinks.
-
Consume minimally processed foods rich in fiber (vegetables, legumes, whole grain products).
-
Keep regular physical activity - it improves insulin sensitivity.
-
Follow quality sleep and control stress - these factors affect the hormonal regulation of appetite and glucose levels.
A reasonable attitude to sugar is not only a matter of figure, but also a key to a healthy and clear mind in the future.
