Study Notes
Nutritional Functions of Minerals
- Essential minerals are vital for various bodily functions and can be found in cereals, meat, fish, dairy, nuts, fruits, and vegetables.
- Approximately 20 minerals are necessary for human function, classified into macrominerals (needed in amounts >100 mg/day) and trace minerals (needed in amounts <100 mg/day).
Key Macrominerals and Their Functions
- Calcium: Important for bone structure, muscle function, blood clotting, and hormone secretion.
- Phosphorus: Contributes to bone and teeth structure, and DNA/RNA formation.
- Potassium: Maintains intracellular fluid volume and is critical for heart muscle contraction.
- Sodium: Regulates extracellular fluid volume, essential for nerve and muscle function.
- Chloride: Aids in acid–base balance and maintains urine/plasma electroneutrality.
- Magnesium: Activates enzymes and supports muscle contraction and signaling.
- Sulfur: Acts as a cofactor in oxidative processes and is a metabolite of methionine.
Key Trace Minerals and Their Functions
- Iron: Integral for red blood cell development and energy metabolism.
- Zinc: Protects cells as an antioxidant and is a coenzyme for numerous enzymes.
- Iodine: Critical for thyroid hormone production.
- Chromium: May enhance metabolism of macronutrients by improving insulin function.
- Copper: Necessary for cellular oxidation and iron metabolism.
- Fluoride: Supports bone and dental health.
- Molybdenum: Assists in metabolizing sulfur-containing amino acids.
- Manganese: Functions as an antioxidant and supports metabolic enzyme activities.
- Selenium: Needed for thyroid function and DNA synthesis.
Absorption and Interactions of Minerals
- Mineral absorption occurs mainly in the small intestine and varies based on specific needs, such as increased calcium absorption during pregnancy.
- Absorption can be influenced by dietary components; for example, iron is better absorbed in an acidic environment, and compounds like phytates can inhibit the absorption of iron, calcium, magnesium, and zinc.
Mineral Intake for Wellness
- Adequate mineral intake is crucial for metabolic and physiologic functions throughout life, with varying needs based on age and sex.
- A balanced diet rich in vegetables, legumes, nuts, lean meats, and seafood generally meets mineral requirements.
- Food fortification has historically addressed deficiencies, such as adding iodine to salt to combat goiter and vitamin D to milk to prevent rickets.
Considerations for Dietary Supplements and Social Media
- There is a growing trend of using single-nutrient supplements; however, food sources are often adequate for most.
- Social media influencers promote micronutrient awareness and the potential use of testing kits to assess individual nutrient levels.
- Critical evaluation of sources on social media is necessary, focusing on evidence-based practices.
Recommendations for Client Education
- Encourage clients to rely on credible, evidence-based sources for nutritional information.
- Suggest alternative educational resources such as government health websites, registered dietitians, and peer-reviewed journals for reliable information on micronutrient needs.
