Study Finds Certain Processed Foods May Be Linked to Lower IQ Scores in Children
A new international study suggests that toddlers who regularly consume large amounts of ultra processed foods could face negative effects on cognitive development later in childhood.
Researchers found that children with diets high in processed snacks, sugary drinks, instant noodles, and processed meats at around two years old tended to score lower on intelligence tests several years later.
Researchers Track Children Over Several Years
The study was conducted using data from the long-running University of Illinois and Federal University of Pelotas research project in Brazil, which has followed thousands of children from birth through childhood.
Scientists analyzed toddlers’ eating habits and later evaluated their cognitive performance when they reached six to seven years old.
The researchers focused on overall dietary patterns instead of individual foods or nutrients.
Foods Linked to Lower Cognitive Scores
According to the analysis, children whose diets included higher amounts of ultra processed foods showed lower IQ test scores during early school years.
Foods commonly associated with the unhealthy dietary pattern included:
Sweet biscuits and candies
Soft drinks
Instant noodles
Processed meats and sausages
Packaged snacks
Meanwhile, healthier eating patterns included foods such as:
Fruits and vegetables
Beans
Natural fruit juices
Traditional home-cooked meals
Why Processed Foods May Affect Brain Development
Although the study did not directly prove cause and effect, researchers believe several biological factors could explain the connection.
Experts say diets high in ultra processed foods may contribute to:
Increased inflammation
Oxidative stress
Poor gut health
Reduced nutritional quality
These factors may potentially affect early brain development during important growth stages.
The strongest effects were reportedly observed in children who already showed early growth or nutritional challenges.
Healthy Foods Still Important
Interestingly, the study did not find a major increase in IQ scores among children following the healthier diet pattern. Researchers suggested this may be because many children in the study already consumed healthy foods regularly, making differences harder to measure.
Still, nutrition experts continue to emphasize the importance of balanced diets during early childhood.
Global Concerns Over Ultra processed Foods
Health professionals worldwide have increasingly warned about rising consumption of ultra processed foods among children.
Many experts believe modern diets filled with heavily processed snacks, sugary drinks, and fast food may contribute to long-term health problems beyond obesity, including potential effects on mental development and learning abilities.
Researchers say the findings may have global relevance because ultra processed foods are now widely available in many countries.
Advice for Parents
Nutrition specialists generally recommend that parents focus on providing children with:
Fresh fruits and vegetables
Whole grains
Protein-rich foods
Limited sugary drinks and processed snacks
Balanced home-cooked meals when possible
Experts also stress that healthy sleep, exercise, education, and family support all play important roles in child development.
Conclusion
The study adds to growing scientific concern about the long-term impact of ultra processed foods on children’s health and development.
While more research is still needed, researchers say reducing highly processed foods during early childhood could help support healthier brain development and long-term learning outcomes.
