What are deficiency diseases?
Deficiency diseases are illnesses that occur when the body does not get enough essential nutrients for a long time. These nutrients include vitamins, minerals, proteins, and carbohydrates that are necessary for proper growth, energy, and body functions.
A balanced diet helps prevent such diseases and keeps the body healthy.
