New Delhi: Children often enjoy eating foods like chips, biscuits, burgers, and French fries. Parents frequently overlook this, viewing it as a normal habit. However, new research suggests that ultra-processed foods may affect not only a child’s weight but also their brain’s responses.
According to the study, the brains of children whose diets are high in ultra-processed foods may become more active when presented with appetizing food. Furthermore, these children were also found to be more likely to experience an increase in body fat and BMI over the following year.
What does the new research say?
Published in JAMA Network Open, the study involved 46 children who initially had a healthy weight. Researchers examined the children’s dietary habits and analyzed their brain activity when shown images of food.
The study found that in children whose daily diets contained high amounts of processed foods, areas of the brain associated with reward, motivation, and habit formation showed increased activity when they were shown items like cookies and French fries.
The research also revealed that these children experienced a more significant increase in BMI and body fat over the course of the following year. An increase in their waist circumference was also recorded.
Is junk food altering children’s eating habits?
The findings raise concerns regarding rising childhood obesity. According to experts, the regular consumption of ultra-processed foods may lead children to develop a habit of constantly seeking out tasty, indulgent foods.
However, this study does not prove that children have become “addicted” to food or that junk food is directly causing physical changes in their brains. The research merely points to a correlation between dietary intake and brain response.
It’s not just sugar—other factors are also responsible.
The research also indicates that sugar alone cannot be held solely responsible for the effects of processed foods. Many ultra-processed foods contain a combination of fat and carbohydrates, which can activate the brain’s reward system.
However, when research accounted for the amount of added sugar, the link between processed foods and the brain’s response weakened somewhat. This suggests that there may be other factors at play.
An important note for parents: It is best to limit the intake of items like chips, biscuits, burgers, and packaged snacks in children’s diets. Instead, focus on incorporating fruits, vegetables, and nutritious foods into their eating habits.
