A well-balanced diet is essential for maintaining optimal health, yet many people unknowingly suffer from nutritional deficiencies. These deficiencies can lead to various physical and mental health issues. Identifying the warning signs can help you adjust your diet and lifestyle to support better health.

Understanding Nutritional Deficiencies

Nutritional deficiencies occur when the body lacks essential vitamins and minerals needed for normal functioning. Poor diet, malabsorption issues, chronic illnesses, and certain medications can contribute to deficiencies.

Common Causes of Nutritional Deficiencies

• Poor diet choices – Processed foods and lack of fresh fruits and vegetables.
• Digestive disorders – Conditions like celiac disease and Crohn’s disease can hinder nutrient absorption.
• Restricted diets – Vegan, vegetarian, and low-carb diets may lack essential nutrients.
• Aging – Nutrient absorption declines with age, affecting calcium, vitamin D, and B12 levels.
• Chronic stress – Depletes key nutrients like magnesium, B vitamins, and vitamin C.
• Alcohol and smoking – Reduce the absorption of essential nutrients.
• Medications – Some prescription drugs can lead to deficiencies.

Recognizing the symptoms of deficiencies is key to preventing long-term health complications.

How to Fix It:

• Eat Vitamin A-rich foods (carrots, sweet potatoes, liver).
