The danger of sugar for the brain (part 2)
2- It affects memory and our learning abilities:
In 2012, a study of rats at the University of California, Los Angeles, concluded that a high-fructose diet slowed the brain literally, impairing the ability to acquire and memorize. The synapses of the rats who had consumed too much were damaged and the communication between the brain cells was altered.
The rats also developed resistance to insulin. This hormone, which regulates glucose levels in the blood and functions of brain cells, also strengthens synaptic connections. The cells can thus better communicate and record information. Over-consumption of sugar results in a deterioration in cognitive functions related to the decline in insulin production.
"Insulin plays an important role in regulating blood glucose, but it may have the opposite effect on the brain." Our study indicates that a high-fructose diet has a negative impact on the body but also on the body. Brain, which had never been established, "says Dr. Fernando Gomez Pinilla, director of the study.
3-It can lead to depression or stress:
If you have ever had hypoglycemia, you may be familiar with these symptoms: irritability, mood changes, fatigue, confusion ... They are linked to sudden changes in blood sugar levels: when eating a donut or We drink a soda, this rate increases suddenly, before dropping just as quickly, resulting in stress, bad mood or depression.
But foods rich in sugar and carbohydrates also stimulate the production of serotonin, a neurotransmitter that improves morale. However, it is only available in limited quantities and can not respond to permanent overactivation.
According to Dr. Datis Kharrazian, an expert in functional medicine and author of Why Is not My Brain Working? This would explain the onset of depressive symptoms. The researchers also demonstrated that chronic hyperglycaemia favored the risk of cerebral inflammation, which could lead to depression.
These effects would particularly affect adolescents. A recent study by the Faculty of Medicine at Emory University, conducted on young rats, found a link between over-consumption of sugar and depressive and anxious behaviors.
4-It acts as a risk factor in cognitive impairment and senility:
Increasing evidence suggests that over-sweet diets may be a contributing factor in the onset of Alzheimer's disease. Research conducted in 2013 suggests that insulin resistance and hyperglycaemia (diabetes characteristics) increase the risk of developing Alzheimer-like neurodegenerative diseases.
They provide "further evidence that hyperglycemia also affects the brain," confirmed endocrinologist Medha Munshi at the New York Times. Some scientists even call nicknamed Alzheimer's "type 3 diabetes". Another sign that diet plays a role in the development of this disease.
