Author bio
Dr Agustín Hernández is a molecular biologist specialising in fungi and with a passion for food. He has worked in plant sciences and microbiology but also in health-related aspects such as cancer. He writes and reviews content on these topics.
Highlights:
- PhD with work done at the Department of Agricultural Sciences, University of Bristol (UK) with work on a corn/maize fungal pathogen.
- The equivalent of a Master’s by Research by the University of the Basque Country (Spain) working in fungal lipids.
- Bachelor in Biological Sciences from the University of the Basque Country (Spain)
- Group leader at Universidade de São Paulo and Universidade Federal de São Carlos (Brazil).
In the UK he worked at IACR-Long Ashton Research Station, a scientific complex dedicated to agricultural products, under the supervision of lipid expert Dr David T. Cooke and plant nutrition expert Dr David T Clarkson.
He has held postdoctoral positions in Belgium (Katholieke Universiteit Leuven) and Spain (Consejo Superior de Investigaciones Científicas) and worked for one year at the laboratory of plant physiologists Ray A. Bressan and P.M. Hasegawa in the Department of Horticultural Sciences of Purdue University (IN, USA).
He is the author of more than 30 scientific papers and contributed to many scientific meetings. Also, he has supervised master’s and PhD students in molecular biology.
In addition to wet-lab work, he has a passion for theoretical enzymology, informatics and writing. He is also an active reviewer for journals like MDPI Nutrients, MDPI Agronomy, and Frontiers in Plant Sciences.

In this brief article, we will answer the question, ”Can you eat graphite?” Also, we will answer for which purpose graphite can be used, and, if graphite is ingested or inhaled accidentally, what could be the consequences.
Read on to know the problems caused by graphite swallowing.
Can you eat graphite?
No, we cannot eat graphite. Our body is unable to use graphite as a nutrient. Although it is not classified as a toxic (1), it is not recommended to eat graphite. In very large quantities, it may block the digestive system .
What is graphite made of?
Graphite is basically a form of carbon in a crystalline form. It has a soft texture. It shows flexibility but not elasticity. It is black colored and opaque. It also has a metallic luster.
Although it is associated with lead (pencil leads, etc.) graphite actually contains no lead metal. The reason for that association is historical. Before chemistry was well developed, graphite was wrongly considered to be a lead-containing mineral and, thus, it passed to the English language (2).
What will happen if we eat graphite?
Graphite is a non-poisonous material. Further, at present, graphite is not considered dangerous, toxic or hazardous (3). If it is eaten by mistake or unintentionally, usually it creates no symptoms. If pencil leads (graphite) are ingested, they may cause choking and, if severe cases, stomachache and vomiting due to intestinal blockage (4).
Can I get lead poisoning if I eat pencil leads?
No, you cannot get lead poisoning by eating or being injured with graphite pencil leads. Pencil “lead” contains only graphite. Graphite contains no lead metal.
Is graphite bad to breathe?
Inhalation of graphite dust for extended periods may cause a type of fibrosis of the lung named graphitosis (5). Graphitosis is also known as a form of pneumoconiosis (lung fibrosis due to inhalation of particles) and may, in severe cases, induce death.
Is Graphite harmful to the environment?
Graphite is a naturally occurring substance. It is close to pure carbon in composition and it shows no significant toxicity for the environment (1).
Conclusion
In this brief article, we have answered the question, ”Can you eat graphite?” Also, we have explained for which purpose graphite can be used, and, if graphite is ingested or inhaled accidentally, what could be its consequences.
Thanks for your feedback!
