Cognitive benefits of good nutrition: Investigating memory performance in young adults

Abstract

Background: During early adulthood Nutrition plays a pivotal role in supporting cognitive functions. Evidence suggests that nutritional deficiencies and imbalanced dietary habits are associated with impaired cognitive performance. However, the precise relationship between specific nutritional indicators and memory in young adults remains insufficiently elucidated.

Aim: The study aimed to investigate the association between nutritional status and memory performance among young adults, focusing on how anthropometric, biochemical, and dietary factors may influence cognitive functioning.

Materials and Methods: This cross-sectional study included 106 healthy participants aged 20–22 years.  A well-structured questionnaire and blood analysis was performed for data collection regarding sociodemographic data, Nutritional status and dietary profile. Memory performance was evaluated using the PGI Memory Scale.

Results: Underweight individuals showed the highest proportion of below-average memory scores, with a statistically significant association between BMI and memory performance in this group. In contrast, participants with normal, overweight, and obese BMI categories exhibited higher proportions of average to excellent memory, though without statistically significant associations. Dietary analysis indicated a balanced intake of cereals, pulses, vegetables, and fruits, but also revealed a high frequency of fast food and sugary item consumption, suggesting a mixed dietary pattern among participants.

Conclusion: The study highlights a significant link between undernutrition and reduced memory performance in young adults, emphasizing the importance of balanced dietary habits during early adulthood. consistent nutritional monitoring and public health strategies are essential to promote cognitive health and prevent the adverse effects of poor dietary patterns.
