There is a common belief that to meet the daily need for glucose, a person needs to consume sugar. Glucose (monosaccharide) is a natural organic compound that provides the metabolic processes in the human body and charges it with energy. Its entry into the blood makes all our organs work more energetically and stimulates intracellular interaction for oxidation and the full course of biochemical reactions.
What is the effect of sugar on brain activity? Its effect begins with getting on the tongue and activating taste receptors, which immediately send signals to the human brain stem. Impulses from the receptors are distributed to the corresponding parts of the brain that process different tastes-bitter, salty, sour, and, in our case, sweet. As a result, the so – called reward system is activated in the cerebral cortex, which allows us to answer the question-is it worth trying it again?
One of the components of the reward system is the neurotransmitter dopamine, which helps determine whether sugar is needed for the brain and other organs. When eating sweets, the level of dopamine in the body increases dramatically, which is perceived as a reward and encourages people to eat desserts again and again. With frequent use of treats, the brain "gets used" to increased levels of dopamine, and a person has a "sugar addiction".
This dependence can be compared to a light drug, because when you completely refuse to eat sweets in the human body, the same reactions occur as when you refuse drugs – tremors, anxiety, the desire to taste the "forbidden fruit"again. The most effective way to get rid of addiction is considered a complete change in the diet with a gradual decrease in the use of sweets.
Despite the high probability of developing addiction, sugar is definitely good for the brain, but only when consumed in moderation. Its benefits are as follows:
– As a result of its activity, the brain uses up to 20 % of the energy produced by the body. Glucose is responsible for energy reproduction, which is quickly absorbed by the body and enters the tissues within half an hour after eating sweets.
– When considering whether sugar is good for the brain, it is worth noting that a normal level of monosaccharide has a beneficial effect on mental activity. It increases the ability to learn, improves memory, and regulates cognitive function.
- Glucose is involved in the synthesis of hormones, including serotonin, and this has a positive effect on the physical and psychological health of a person.
Thus, the effect of sugar on the human brain can be both positive and extremely negative. However, its negative impact does not mean that you need to completely abandon the sweet. Regular abuse of treats over time will cause addiction and bad effect on the brain, but sometimes eaten a small piece of cake or cake does not hurt at all.
