Adolescent milk intake linked to enhanced brain and cognitive development, study finds

Adolescence is a critical period for both physical growth, including height and skeletal development, and significant cognitive advancement. Ensuring adequate nutrition during these years is vital, and recent research is highlighting the role of milk consumption beyond its well-known benefits for bone health.

A study by researchers at Toronto Metropolitan University in Canada, published in the journal 'Applied Physiology, Nutrition, and Metabolism,' investigated the cognitive performance of 54 children aged 9 to 14. The study compared cognitive tasks based on the intake of various dairy products, including milk, yogurt, and cheese, against a control group that consumed no snacks.

“

The findings indicated that children who consumed milk showed relatively positive results in tasks assessing spatial working memory.

The findings indicated that children who consumed milk showed relatively positive results in tasks assessing spatial working memory. This type of memory, which involves temporarily holding and utilizing visual and sequential information, is crucial for various cognitive activities such as learning and problem-solving.

This research is noteworthy as it examines the relationship between milk consumption and cognitive performance in growing children, offering a broader perspective on milk's role beyond the conventional understanding of 'milk equals bone health.'

This research broadens the understanding of milk's role, moving beyond the traditional association with "bone health" to include its potential contribution to cognitive functions. Given that the adolescent brain is undergoing rapid development, adequate nutrient intake is essential. Milk is highlighted as a convenient source of key nutrients like calcium and protein, which support both physical and cognitive growth.

However, the article notes that many Korean adolescents struggle to maintain regular meals, with a significant percentage skipping breakfast. According to the 2025 Youth Health Behavior Survey, breakfast skipping rates were 41.9% for male students and 45.3% for female students, rising to 44.6% and 47.2% respectively for high school students. In this context, milk can serve as an accessible way to supplement essential nutrients during the school day, whether with breakfast or as a snack.
