The scientific debate on nutrition has changed a lot in recent years. Recent studies show that sugar is one of the worst things for human health. However, most people are not aware that the harmful effects of sugar also affect the brain.
In addition to being linked to heart disease and diabetes, sugar causes a wide range of problems with the mind. In this article, we will talk about its most harmful effects.
So sugar has harmful effects?
As we grew up, we were pushed into perceptions of health and nutrition that are completely wrong. For example, many of us were taught that the biggest risk factor for heart disease is fat consumption, and so light products took over the market.
Sugar was really advertised for a long time as a completely harmless substance with no bad effects on health. Then a study conducted in 2016 showed that the sugar industry had bribed researchers. What was their goal? It was to conceal the facts about how harmful sugar is. Today, we know that sugar is directly linked to cancer and heart disease.
Sugar is addictive
Sugar addiction is a real problem. Today, it affects more and more people. Those affected by this disorder feel that they need to consume more and more sugar to feel good. Those who decide to eliminate sugar from their diet experience really unpleasant side effects during the first few days.
For example, a person who is hooked on sugar after leaving it may experience headaches, dizziness, muscle weakness, anxiety, and stress. Fortunately, these symptoms are not permanent. They only last until the body gets used to functioning without sugar.
How does this addiction work? When sugar is absorbed by the body, it releases large amounts of endorphins into the brain. Therefore, whenever we feel dissatisfied in some area of life, we need to get sugar in order to feel good.
Sugar causes problems with memory and comprehension
A study at the University of California that looked at the effects of consuming fructose (a sugar found in fruits, vegetables, honey) revealed that it has detrimental effects on brain synapse formation. This means that eating plenty of fructose impairs the brain’s ability to understand and make new connections.
Researchers have also shown that people who consume a lot of fructose have low BDNF levels. This substance (a brain-derived neurotrophic factor) has a profound effect on our ability to create new memories and learn new knowledge.
Some studies suggest that sugar consumption may be directly related to Alzheimer’s. In fact, the medical community is considering classifying this disease as type 3 diabetes.
Sugar affects our mood
Our cognitive abilities are not the only thing at stake. Our mood varies tremendously due to glucose. Due to its effect on our body’s insulin, sugar spikes can cause depression, anxiety, and sudden mood swings.
In the long run, these harmful effects of sugar may even worsen. When we ingest glucose, our brains release serotonin. Serotonin is a neurotransmitter that makes us feel pleasure. But the stores of this substance in the body are not limitless. Each time the brain releases serotonin, its amount in the brain decreases.
For this reason, a person who has not consumed large amounts of sugar for a long time experiences how difficult it is to feel a constant positive feeling.
Sugar prevents us from feeling satisfied
Finally, studies have shown that glucose “captures” our saturation system. For this reason, eating too much sugar makes us feel hungry all the time. This has a direct link to overweight and obesity.
The effects of sugar on oxytocin and its function are a problem. The consequences for our brains can be even more shocking. If we want to avoid the harmful effects of sugar and maintain good physical and mental health, we must try to reduce sugar consumption as much as possible.
