Lesson Content/Board Summary

Food Nutrients1

Prevention and Treatment of Nutrient Deficiency Diseases

Nutrient deficiency diseases occur when the body does not get enough essential nutrients. They can lead to health problems like anemia, rickets, scurvy, and night blindness. Preventing these diseases involves proper diet, supplementation, and hygienic food handling.

The following are methods of prevention and treatment:

Eating a balanced diet containing vitamins, minerals, proteins, and carbohydrates.
Using fortified foods or supplements as prescribed by health professionals.
Practicing good hygiene to avoid foodborne illnesses.
Regular health check-ups to detect early signs of deficiency.
Educating families and communities on proper nutrition.

Care of Nutrient-Related Diseases

Proper care involves recognizing early symptoms and taking corrective action promptly. This ensures that affected individuals recover and maintain good health.

These include:

Administering the correct nutrient supplement (iron, vitamin D, vitamin C, etc.).
Preparing meals rich in the deficient nutrient.
Encouraging rest and proper hydration during illness.
Seeking medical advice when symptoms persist.
Avoiding dietary habits that may worsen the deficiency.
