"Nerve cells need a constant supply of glucose, the most important fuel," says Dr. Jorge Pamplona Roger from the University of Granada in Spain. "When the blood sugar level falls, it leads to a lack of mental concentration, apathy and a decline in intellectual performance."
When consuming many foods rich in refined sugars and low in vegetable fiber, the glucose content rises sharply. Thereby insulin is made to bring back the glucose level of the blood to the original level.
These fluctuations have a great influence on the functioning of nerve cells and can lead to mood swings, irritability, nervousness, apathy, hyperactivity, emotional imbalance and aggressive behavior. In addition, additives, dyes, preservatives, sweeteners and other additives approved by the European Union (E numbers) can lead to hyperactivity and nervousness.
A study in the UK recently concluded that certain additives used in soft drinks, sweets and other sweets stimulate behavioral changes, especially in children between 3 and 9 years old. These children were less able to carry out or play a task after exposure to the additives and exhibited impetuous behavior and a lack of concentration.
Additives that have the most influence on the behavior are artificial colors, preservatives, flavorings and various sweeteners. Although these substances are legal, just like alcohol and tobacco, it does not necessarily mean that they are safe.
