How can deficiency diseases be prevented?

Deficiency diseases can be prevented by eating a balanced diet that provides all essential nutrients, including carbohydrates, proteins, healthy fats, vitamins, and minerals. A varied diet with fruits, vegetables, whole grains, pulses, milk, eggs, nuts, and other nutrient-rich foods helps meet the body's nutritional needs.

Other preventive measures include using iodised salt, getting adequate sunlight for Vitamin D, maintaining good food hygiene, and following healthy eating habits. Children, pregnant women, and older adults may also need nutritional supplements if recommended by a healthcare professional.
