Scientists in Australia have found that if teenagers aged 14~ 17 often eat hamburgers and French fries, their cognitive function will also be affected.

Scholars from the University of Western Australia and Trathen Institute of Children's Health selected 602 participants, each of whom filled out a questionnaire about eating habits at the age of 14 to determine their health status and eating habits.

When the participants reached the age of 17, the researchers assessed their cognitive abilities. The results show that teenagers who often eat hamburgers, French fries, processed meat products and drink soft drinks are slightly worse than other children in reaction time, intelligence level, visual attention, learning and memory ability. Teenagers who eat more fruits and green leafy vegetables have better cognitive function.

Dr Annette Nayaladi, the author of this study, said: "This may be related to the micronutrients contained in green leafy vegetables, which help to enhance cognitive function. Omega-6 fatty acids in fried food and red meat may affect the development of children's cognitive function.

Intake of a large number of omega-6 saturated fatty acids and simple carbohydrates will affect the function of hippocampus, which is an important part of learning and memory in the brain and will increase in size during adolescence. Adolescence is an important stage of brain development, and unhealthy diet may affect this process. The results of this study have positive reference significance for the formulation of health policy in the future.
