It is a common misconception that fingernails have no nutritional value. In fact, 10 fingernails are said to contain 20 calories and 5g of protein. However, it is important to note that fingernails are made of keratin, a difficult-to-digest protein, meaning that the calories gained from eating fingernails are negligible compared to the calories burned during the process.

| Do fingernails have calories? | Yes, 10 fingernails contain approximately 20 calories. |
| Are fingernails nutritious? | Fingernails are made of keratin, a difficult-to-digest protein. They have low nutritional value. |
| Can you survive by eating fingernails? | No, you will likely burn more calories eating them than you would gain. |

What You'll Learn
Fingernails are made of keratin, a difficult-to-digest protein
While fingernails do contain calories, they are made of keratin, a difficult-to-digest protein. This means that the calorie content of fingernails is very low. In fact, you would likely burn more calories eating your fingernails than you would gain from them.
Keratin is a protein found in various tissues in the human body, including hair and nails. It is a structural protein that provides strength and rigidity to these tissues. While it is a valuable protein, it is not a significant source of nutrition due to its low digestibility.
The digestibility of keratin can be improved by properly preparing it. For example, grinding fingernails into a fine powder may increase the bioavailability of the keratin. However, this process can be time-consuming and may not provide a substantial nutritional benefit.
Additionally, fingernails may contain other nutrients besides keratin. For example, they have been shown to contain small amounts of protein and carbohydrates. However, these amounts are likely negligible and do not significantly impact the calorie content of fingernails.
Overall, while fingernails are made of keratin, a difficult-to-digest protein, they do contain a small number of calories. However, the process of consuming and digesting fingernails may offset any potential nutritional benefit. Therefore, it is not a recommended source of nutrition.

Fingernails have very few calories
Fingernails are made of a protein called keratin, which is challenging for the body to digest. As a result, fingernails have very few calories. While they do contain some calories, the amount is negligible, and you would likely expend more energy trying to eat them than you would gain from doing so.
The calorie content of fingernails is so low that commercially available keratin is listed as having zero calories per 250mg serving. This means that even if you were to consume a significant amount of fingernails, you would not be adding any substantial calorie intake to your diet.
It is worth noting that the act of biting and ripping off fingernails can be painful and is not recommended. Additionally, there may be other health risks associated with consuming large amounts of fingernails, such as potential intestinal blockages.
While fingernails may have a very small number of calories, it is important to understand that they do not provide any significant nutritional benefit. Most calories come from carbohydrates, not proteins, so even if you were to properly powder and prepare keratin to make it more digestible, it would still not be a substantial source of energy.

Fingernail clippings may have more calories than the nails themselves
It is a widely held belief that fingernails have calories. However, this notion has been contested by some who argue that the calories burned while eating fingernails are more than the calories gained from consuming them. This is because fingernails are made of keratin, a type of protein that is challenging for the body to digest. As a result, the act of consuming fingernails may actually result in a net loss of calories.
Despite this, it is important to note that fingernail clippings may contain more calories than the nails themselves. This is due to the presence of dirt, sebaceous secretions, fungi, and other substances that can accumulate under the nails. These substances can provide additional nutritional value, including fat and protein. Therefore, while the nails themselves may not be a significant source of calories, the act of clipping them and ingesting the clippings, dirt and all, could provide a marginally higher caloric intake.
Furthermore, the method of preparation can also impact the calorie content of fingernails. Some sources suggest that properly powdering and preparing keratin can increase its bioavailability, making it a more mediocre source of protein. However, this process may not be feasible for everyone, and the overall calorie gain may still be negligible compared to the effort expended.
While it is true that fingernails themselves have minimal nutritional value, it is worth noting that personal hygiene plays a crucial role in this context. Dirty fingernails may harbour bacteria and other microorganisms that can be harmful if ingested. Therefore, it is generally not recommended to consume fingernails or their clippings, regardless of their calorie content.
In conclusion, while fingernails themselves may not be a significant source of calories, the presence of dirt and other substances in fingernail clippings can marginally increase their calorie content. However, the act of consuming fingernails may result in a net loss of calories due to the effort expended, and it poses potential health risks due to poor hygiene.

Fingernails may have more nutritional value if powdered
Fingernails are made of a protein called keratin, which is challenging for the body to digest. As a result, eating fingernails may provide very few calories, and the body may burn more calories during the process of eating them. However, researchers have found that when properly powdered and prepared, keratin can become a mediocre source of protein.
Powdering fingernails may increase their nutritional value by improving the body's ability to digest keratin. While whole fingernails can be difficult for the body to break down, powdering them increases the surface area available for digestive enzymes to act upon, potentially making it easier to extract nutrients.
Additionally, powdering fingernails may also help prevent intestinal blockage. When ingested, whole fingernails can potentially ball up in the intestinal tract, causing a blockage. Finely powdering the fingernails before consumption reduces the risk of this occurring.
However, it is important to note that even when powdered, fingernails may still provide very little nutritional value. Most calories typically come from carbohydrates, not proteins, and commercially available keratin is often listed as having zero calories per serving. As such, the nutritional benefit of consuming powdered fingernails may be negligible.
In conclusion, while powdering fingernails may theoretically increase their nutritional value by improving digestibility, the overall nutritional benefit is likely minimal. The process of powdering and preparing the fingernails may also expend more energy and resources than can be gained from consuming them.

Hair has more nutritional value than fingernails
While it is true that fingernails do contain calories, with 10 fingernails containing around 20 calories and 5 grams of protein, hair has been found to have more nutritional value than fingernails.
Hair and fingernails are made of keratin, a difficult-to-digest protein. However, if properly powdered and prepared, keratin can become a source of protein.
The nutritional value of hair can be increased if it is dirty. The more complex the dirtiness of the hair, the better its potential nutritional value. For example, hair containing dirt with compost, dandruff, sebaceous secretions, different kinds of fungi, and non-microscopic bugs and their eggs, can provide some nutritional value.
Unlike hair, fingernails do not have the same capacity to increase their nutritional value.
In addition, hair contains more vitamins and nutrients than fingernails. For example, vitamin A can affect the production of sebum, which helps keep hair healthy. A vitamin A deficiency is associated with hair loss and can also increase the risk of acne. Vitamin E may also support hair growth, and avocados are a great source of this vitamin. Similarly, soybeans may promote hair growth, and red meat is rich in a type of iron that is easy to absorb and may aid hair growth.
Therefore, while fingernails do contain some calories and protein, hair has been found to have more nutritional value.
