Childhood Junk Food Permanently Alters Brain Structure, Study Finds

Kathmandu. A recent scientific study on how our childhood diet deeply affects the brain has revealed a surprising fact.

A study has shown that consuming excessive amounts of junk food in childhood can permanently alter the structure of the brain. The most surprising thing is that even adopting a completely healthy diet in adulthood does not fully reverse that previous damage to the brain.

According to a study by University College Cork published in 'Nature Communications', children who regularly consume high-fat and high-sugar foods may experience permanent changes in their brains. It has also been found that consuming such foods, which lack sufficient nutrients in childhood, can permanently alter our eating habits in the future. This directly affects the parts of the brain that control our appetite.

• Negative Impact on Memory and Concentration

Junk food not only increases our body weight but also slows down brain function. Research has clearly shown that excessive consumption of junk food weakens a person's memory, ability to concentrate, and capacity to learn new things.

Researchers discovered this fact through a study on mice. Animals that were fed a diet high in fat and sugar at the beginning of their lives showed permanent changes in their eating habits as they aged. Scientists have directly linked this change to disturbances in the 'hypothalamus'. The hypothalamus is a crucial part of the brain that controls our appetite and energy balance.

• Is there any cure?

Although the damage to the brain from junk food can be permanent, scientists have also pointed out some relief. According to research, these negative effects can be reduced to some extent by consuming some beneficial gut bacteria and prebiotic fiber.

'Our findings clearly show that what we eat at the beginning of life really matters,' said study author Dr. Kristina Cuenca-Martínez, summarizing the findings.
