Although chicken is delicious and nutritious, it is recommended to avoid eating the following 4 parts:

1.   Chicken Skin
Many people enjoy eating chicken skin because of its crispy texture and taste. However, chicken skin is high in fat and can harbor parasites and bacteria if not cleaned properly.

2.   Parson's Nose (Pygostyle)
This part of the chicken is often favored for its unique flavor and texture. Despite this, the parson's nose contains lymphoid tissue that can harbor harmful bacteria and viruses, making it a risky part to consume.

3.   Chicken Lungs
Chicken lungs, like other internal organs, are involved in detoxifying the body and can contain many parasites and bacteria, even after cooking. Consuming them can lead to discomfort and potential health issues.

4.   Chicken Head
Chicken heads are sometimes eaten for their unique taste and texture. However, they can contain bacteria, toxins, and heavy metals that can accumulate in the body and pose health risks, especially for children.

Conclusion:

These parts of the chicken are known to contain higher levels of parasites and bacteria, and it is advisable to avoid them to reduce health risks.
