The average person sheds between 100 and 150 hairs every day, making a stray hair in food a common issue. While the phrase 'beard meat' is a misconception, we delve into the potential health risks associated with beard hair contamination and discuss how to maintain proper hygiene.

The average person sheds between 50 and 100 hairs per day. This raises a curious question: does hair have calories? Despite being made of protein, hair provides no nutritional energy for humans because our digestive systems are not equipped to break it down.

Hair is composed of a protein called keratin, which is exceptionally strong and resilient. So, do you get protein if you eat hair? The short and definitive answer is no, because your body's digestive system is not equipped to break down this tough protein.

Made primarily of a tough, fibrous protein called keratin, hair might seem like a potential source of nutrition. However, despite this protein content, the human body cannot properly digest or absorb any nutritional value from hair. This article explores why hair does not count as a dietary protein source and the reasons behind its indigestible nature.

Over 90% of a chicken feather's dry matter is keratin, yet humans cannot derive nutritional value from this protein. The reason is our digestive system is not equipped to break down the resilient, insoluble protein found in hair, nails, and feathers.

Affecting a significant number of pregnant women, children, and people with intellectual disabilities, the behavior of eating unusual foods is a complex and often misunderstood condition known as pica. This eating disorder involves compulsively consuming non-nutritive substances, which can have serious health consequences depending on the items ingested.

The human digestive system cannot break down the protein keratin, meaning the number of calories are in one hair is zero. While hair is technically composed of proteins, fats, and minerals, these components are locked within a tough, insoluble structure that our bodies lack the enzymes to process.

According to the National Eating Disorders Association, nutrient deficiencies like iron and zinc are thought to be common causes of pica, the eating disorder of which hair chewing is a type. This compulsive behavior, medically known as trichophagia, can also have significant psychological and behavioral roots.
