There are many reasons why your poop might smell like cheese. One possibility is that you have been consuming large quantities of dairy products, which can cause an increase in the bacteria that produce smelly compounds in your gut. Another reason could be that you have a digestive disorder that affects your ability to properly break down and absorb nutrients from food, leading to excess gas and a strong odour. Additionally, certain medications or supplements can contribute to changes in gut bacteria and result in altered stool odour. While it may be unpleasant, having poop that smells like cheese is typically not a cause for concern unless accompanied by other symptoms such as abdominal pain, fever, or changes in bowel habits.

What You'll Learn
Poop-smelling cheese is often washed in fermented juice or liquor
While there are many reasons why poop may smell like cheese, one possible explanation is the consumption of certain foods. For instance, foods rich in sulfates, such as eggs, broccoli, and cauliflower, can cause stools to emit a sulfur or rotten egg smell. Additionally, dietary changes or incorporating probiotics can help alleviate foul-smelling stools.
In some cases, poop-smelling cheese may be attributed to the presence of particular bacteria in the cheese-making process. For example, Leuconostoc bacteria, commonly found in pepper ferments, can produce a byproduct called dextran, which may result in a slimy texture and an unpleasant odor. However, with extended fermentation, the odor tends to dissipate, and the final product remains edible and tasty.
It is worth noting that the smell of poop-smelling cheese may also be influenced by the type of milk used and the production method. For instance, cheese made from pasteurized cow's milk with a texture resembling Parmesan may have a rind that smells like manure due to the presence of "barnyard" aroma profiles in the milk. This cheese is typically vacuum-packed for transport and left unwrapped upon arrival to allow it to breathe.
To address the issue of poop-smelling cheese, some people suggest scraping or cutting away the rind, as it is usually not eaten anyway. Alternatively, serving the cheese warm or pairing it with sweeter items like fruit can help mask the unpleasant aroma.

The rind is usually the source of the smell
The human gut is a complex environment, home to billions of microorganisms, including bacteria, viruses, and fungi, collectively known as the gut microbiota. These microbes play a crucial role in maintaining our health, and their balance is essential for optimal bodily functions. When it comes to the smell of our poop, or stool, several factors come into play, and one of the key players is the rind, which is often the source of that distinctive cheesy odour.
The rind, or the outer layer of the stool, is where many of the odour-causing compounds are found. This layer is formed during the digestive process, as bile salts and other compounds interact with the contents of the intestine. The rind can vary in thickness and texture, and a thicker rind often corresponds to a stronger smell. This is because a thicker rind provides a larger surface area for bacteria to act upon, resulting in the production of more odorous compounds.
The bacteria in our gut play a significant role in determining the smell of our poop. Different bacteria produce different types and amounts of gases, which contribute to the overall odour. The rind, being rich in bacteria, becomes a hotspot for microbial activity, especially when the stool is in the colon or sitting in the toilet. The bacteria feast on the remaining nutrients in the waste, producing various gases, including hydrogen sulfide, which has a characteristic rotten egg smell, and volatile fatty acids, which contribute to a cheesy or rancid odour.
Additionally, the rind can also trap and concentrate certain odorous compounds, making the smell more intense. This is similar to how the rind of a cheese can trap and concentrate the flavours produced by bacteria during the ageing process, resulting in a stronger-tasting cheese. In the case of poop, the rind can act like a seal, preventing the escape of gases produced by bacteria, thus intensifying the smell over time.
While the rind is often the source of the cheesy smell, it's important to remember that our diet, gut health, and other factors also play a role in determining the odour. A high-fat diet, for example, can lead to steatorrhea, or fatty stool, which is associated with a strong smell. Infections, inflammatory bowel diseases, and other medical conditions can also cause foul-smelling poop. Therefore, while the rind is usually the culprit, it's crucial to consider other factors and seek medical advice if the smell persists or is accompanied by other symptoms.

Some bacteria cause cheese to smell like poop
Human faeces can smell like cheese due to the presence of bacteria in the large or small intestines. The human digestive system is a complex environment, housing trillions of microorganisms, including bacteria, viruses, and fungi, collectively known as the gut microbiota. These microbes play a crucial role in maintaining our health, aiding in digestion, and even influencing our mood and behaviour.
While most of these bacteria are beneficial or neutral, certain types of bacteria can produce foul-smelling compounds that contribute to the odour of our stool. For example, bacteria in the gut can break down proteins and other compounds in food, producing by-products like hydrogen sulfide, indole, and skatole, which have strong, unpleasant odours.
In some cases, an overgrowth of harmful bacteria or an imbalance between "good" and "bad" bacteria in the gut can lead to particularly smelly stool. This imbalance, known as dysbiosis, can occur due to various factors, including diet, antibiotic use, or underlying health conditions. For instance, consuming high-sulfate foods like eggs, cabbage, broccoli, and cauliflower can result in sulfur-smelling stool, resembling the scent of rotten eggs.
Interestingly, the connection between bacteria and odour is not limited to human physiology; it also plays a significant role in the production of certain cheeses. Researchers like Christina Agapakis have created unique cheeses using human bacteria from various body parts, including belly buttons and tongues. These cheeses emit a range of odours, from fragrant to fetid, highlighting the influence of bacteria on the smells we encounter daily.
While cheese made from human bacteria may seem unconventional, it serves as a thought-provoking project, challenging societal perceptions of acceptable odours and our relationship with the microbial world. Ultimately, whether it's the smell of poop or cheese, bacteria play a pivotal role in shaping our sensory experiences and maintaining the delicate balance of our internal ecosystems.

The smell of cheese is usually stronger than the taste
The smell of cheese is usually stronger than its taste. Similarly, foul-smelling stools can be caused by dietary habits, certain medications, or underlying health conditions. While stools normally have an unpleasant smell, they may sometimes have an unusually strong, foul, or putrid odour. This could be due to the presence of certain stool bacteria, which produce different gases that result in a strong smell.
Dietary factors that can contribute to foul-smelling stools include consuming foods rich in sulfates, such as broccoli and eggs, or sugar-free foods containing sorbitol. Additionally, high-fat meals, red meat, processed meats, butter, cheese, cream, coconut and palm oils, sweets, and desserts can lead to steatorrhea, or fatty stool, which is characterised by a bad smell, pale colour, and looser consistency. Alcohol consumption can also worsen symptoms of steatorrhea.
Certain medications, such as antibiotics and hormones, can disrupt gut bacteria and affect the speed at which stool moves through the intestines, leading to malabsorption of nutrients and smelly diarrhoea. Lactose intolerance, caused by the body's inability to break down lactose, can result in smelly diarrhoea if dairy products are consumed.
Foul-smelling stools can also indicate underlying health conditions, such as intestinal infections like Clostridium difficile (C. diff) or giardiasis, caused by the parasite Giardia. Other potential health conditions include inflammatory bowel disease (IBD), Crohn's disease, ulcerative colitis, cystic fibrosis, pancreatic conditions, short bowel syndrome, and celiac disease. In some cases, a strong stool odour may be indicative of a serious health concern, especially when accompanied by other symptoms such as abdominal cramps, diarrhoea, or changes in stool size, colour, or frequency.

Some people enjoy eating stinky cheese
It's understandable if you're concerned about your poop smelling like cheese. While stool never smells good, it can sometimes take on an even more unpleasant odour than usual. There are several potential reasons for this, ranging from dietary factors to underlying health conditions. Here are some possible explanations for why your poop might smell like cheese:
Dietary Habits:
- Diet is the most common cause of bad-smelling stool. Certain foods can directly contribute to the odour, such as those rich in sulfates, which can lead to a rotten egg smell.
- High-fat meals and snacks, including red meat, processed meats, butter, cheese, cream, and coconut and palm oils, can result in steatorrhea, or fatty stool, which may have an unpleasant smell.
- Sugar-free foods, especially those containing sorbitol, can also make your stool smell worse. Sorbitol acts as a laxative and is known to have a stinking smell.
- Alcohol consumption can also affect the smell of your poop by influencing the function of organs like the intestines.
Underlying Health Conditions:
- Foul-smelling poop can be a symptom of an infection or underlying health condition. Intestinal infections, such as Clostridium difficile (C. diff) or parasitic infections like giardiasis, can cause distinctive foul-smelling stools.
- Conditions affecting the digestive system, such as inflammatory bowel disease (IBD), Crohn's disease, ulcerative colitis, irritable bowel syndrome (IBS), or celiac disease, can lead to smelly stools.
- Imbalances between "good" and "bad" bacteria in the digestive system can also contribute to unusual stool odours.
- In some cases, the presence of blood in the stool can result in a foul smell and may indicate a gastrointestinal issue.
If you are concerned about the smell of your poop, it is advisable to consult a healthcare professional. They can provide guidance, perform any necessary tests, and recommend appropriate treatments or dietary changes to address the issue.
