According to a new study from University College Cork, diets high in fat and sugar early in life may affect the brain well into adulthood. Researchers also found that certain gut bacteria and fibers could help reduce some of the long term effects, reports Science Daily
Early junk food exposure may affect the brain
Researchers found signs that unhealthy eating habits during childhood can change how the brain regulates appetite and eating behavior.
The effects may continue into adulthood
Even after switching to a healthier diet and returning to a normal weight, changes in eating behavior were still observed.
Sugar and fat played a major role
The study focused on diets high in sugar and fat, which researchers linked to the behavioral changes.

Brain regions linked to appetite may be altered
Researchers connected the changes to the hypothalamus, an area of the brain involved in appetite and energy balance.
Many children are exposed to junk food early
The researchers noted that heavily processed foods are widely available and often marketed directly toward children.
Sugary and fatty foods are common in daily life
According to the study, these types of foods are often present at birthday parties, school events, and sports activities.
Food preferences may develop early
The findings suggest that children can form long lasting preferences for certain foods from an early age.

The risk of obesity may increase later in life
Researchers believe the brain changes linked to unhealthy diets could raise the likelihood of obesity in adulthood.
Gut bacteria may play an important role
The study also explored whether the gut microbiome could help counter some of the lasting effects.
One bacterial strain showed promising results
Researchers highlighted the strain Bifidobacterium longum APC1472, which improved feeding behavior in the study.
Fibers were also part of the research
The team tested prebiotic fibers such as FOS and GOS, which are naturally found in foods like onions, garlic, and bananas.
