Causes: Inadequate intake due to the diet, bleeding (menstruation), or poor absorption.
Sources: Red meat, poultry, fish, lentils, beans, spinach, and fortified cereals.

Symptoms:
Bone pain and muscle weakness
Increased susceptibility to infections
Fatigue and depression
Delayed wound healing
Causes: Limited sun exposure, or inadequate dietary intake.
Sources: Sunlight, fatty fish (salmon, mackerel), fortified milk, and egg yolks.
3. Vitamin B12 Deficiency
Role of Vitamin B12: Important for red blood cell production and nervous system function.
Symptoms:
Fatigue and weakness
Numbness or tingling in hands and feet
Difficulty concentrating and memory problems
Glossitis (inflamed tongue)
Causes: Poor absorption (e.g., in pernicious anemia), vegetarian or vegan diets.
Sources: Animal products like meat, fish, eggs, dairy, and fortified plant-based foods.
4. Calcium Deficiency
Role of Calcium: Critical for bone health, muscle contraction, and nerve function.
Symptoms:
Muscle cramps and spasms
Brittle nails
Osteopenia or osteoporosis (weakened bones)
Numbness or tingling in extremities
Causes: Inadequate dietary intake or poor absorption.
Sources: Dairy products, leafy green vegetables, almonds, and fortified non-dairy milk.
5. Magnesium Deficiency

Irregular heartbeat
Mood changes or irritability
Causes: Poor dietary intake, excessive alcohol use, or chronic diseases.

Poor development or growth
Megaloblastic anemia
Causes: Nutritionally bad diet, being pregnant or alcoholism
Sources: Green leafy vegetables, legumes, citrus fruits, and fortified grains
8. Zinc Deficiency

Slow wound healing
Hair loss or thinning
Loss of taste or smell
Causes: Poor diet or absorption diseases (Crohn's disease).
Sources: Meats, shellfish, legumes, seeds, and nuts.
9. Potassium Deficiency

Conclusion
Nutrient deficiencies can severely affect both physical and mental health, but many are preventable or reversible with dietary changes or supplementation. Therefore, meeting the nutrient needs is obtained through a balanced diet rich in whole, unprocessed foods. Regular health check-ups and consultations with a healthcare provider help identify and address deficiencies before these become serious health issues.
