Study Notes
Micronutrients and Cognition in Adolescents
- Micronutrient deficiencies can lead to:
- Weakened immunity
- Impaired cognitive function
- Anemia
Micronutrient Intake in the US
- National Health and Nutrition Examination Survey (NHANES) data highlights:
- Approximately 30% of Americans do not meet iron intake recommendations.
- People living in rural areas have significantly lower nutrient intake than those living in urban areas.
- A significant percentage of women, including pregnant and lactating women, do not get enough iodine.
Micronutrients and Cognitive Function
-
Micronutrients crucial for cognitive function during pregnancy and early childhood, and learning, memory, and mental health throughout childhood:
- Iron (Fe)
- Magnesium (Mg)
- Selenium (Se)
- Iodine (I)
- Zinc (Zn)
- Copper (Cu)
-
Deficiencies in these micronutrients, known as "Generalized Global Micronutrient Deficiencies," impact bodily functions and can impair learning abilities.
Key Minerals for Optimal Cognitive Function in Childhood
- Iron (Fe): Essential for myelination and brain cell development.
- Zinc (Zn): Supports attention, learning, and memory.
- Magnesium (Mg) and Copper (Cu): Contribute to nervous system function and brain health.
- Selenium (Se): Acts as an antioxidant, protecting against oxidative stress.
Food Insecurity and Dietary Diversity
- Globally, 28.9% of the world's population experiences moderate or severe food insecurity.
- Dietary diversity (DD) measures the intake of different food groups over time and is an indicator of nutritional status.
- Both food insecurity (FI) and DD are linked to health outcomes.
Food Insecurity in the USA
- 13.5% (18 million) of US households experience food insecurity.
- Research on adolescent nutrition is under-invested, which inhibits the development of adolescent-responsive nutrition policies.
- Nutritional effects during adolescence extend beyond physical growth to include cardiorespiratory fitness, neurodevelopment, and immunity.
Micronutrient Importance for Overall Health
- Micronutrients like Fe, Cu, Zn, I, Mg, and Se play crucial roles in human metabolism from pregnancy to older adulthood and maintaining overall health.
- Inadequate intake of essential micronutrients can contribute to various disease states, characterized by disturbed homeostasis of redox active metals, leading to neurological disorders, mental health problems, cardiovascular disease, cancer, and diabetes.
