Body odour is an unpleasant topic, but an important one. The food we eat can contribute to our body's natural scent, and certain foods may make body odour worse. Some foods can cause foul smells in our sweat, bad breath, and flatulence. For example, foods with strong smells like garlic, onions, radishes, and spices can cause body odour, as can alcohol and tobacco products. Meat consumption has also been linked to body odour, with a small study finding that the sweat of men on a vegetarian diet was judged to be less pungent than those who ate meat. In addition, vitamin and mineral deficiencies, as well as poor gut health, can lead to body odour. To reduce body odour through diet, it is recommended to consume foods rich in chlorophyll, such as leafy green vegetables, and citrus fruits, which can help neutralize odour-causing compounds. Probiotic-rich foods can also aid in improving gut health and reducing body odour.
How to reduce body odour through diet:
| Characteristics | Values |
|---|---|
| Avoid | Garlic, onion, cumin, leeks, chives, red meat, cauliflower, milk, coffee, alcohol |
| Consume | Yogurt, apples, citrus fruits, herbal tea, peppermint tea, jasmine tea, celery, asparagus, fish, fenugreek seeds, pumpkin seeds |

Avoid odour-inducing foods like garlic, onions, meat, and asparagus
Garlic, onions, meat, and asparagus are common foods known to induce body odour. Body odour is caused by the interaction of sweat with the bacteria on the skin. While sweat itself is mostly odourless, composed of water and salt, the apocrine sweat glands, found in places like the armpits, release sweat that contains proteins. The bacteria on the skin feed on these proteins and release acids that have a pungent smell.
Garlic and onions contain sulphur compounds that can exit the body through the pores, leading to an unpleasant body odour. To combat garlic breath, it is recommended to eat certain foods alongside garlic, such as lettuce, chicory, celery, potato, parsley, mint leaves, peppermint, basil, mushroom, and apples, which seem to destroy the odour. Mint, in particular, contains high levels of phenolics, which react with the sulphur compounds in garlic to produce odourless molecules.
Meat consumption, especially red meat, has been found to negatively impact body odour. In a study, the body odour of participants on a meat diet was judged as less attractive, less pleasant, and more intense compared to those on a non-meat diet.
Asparagus contains asparagusic acid, a sulphur-containing compound that can cause a distinct odour in urine after its consumption. This odour can be detected as early as 15 minutes after eating asparagus and may last up to 35 hours. However, it is worth noting that not everyone experiences or is able to smell this effect, which is known as asparagus anosmia.
By being mindful of the consumption of these odour-inducing foods and incorporating odour-fighting foods into the diet, individuals can take control of their body odour and maintain better personal hygiene.

Consume probiotic-rich foods to restore good intestinal bacteria
Consuming foods rich in probiotics can help to restore good intestinal bacteria and reduce body odour. Probiotics are live microorganisms that offer numerous health benefits, particularly for gut health. They can aid digestion and support a healthy immune system and metabolism.
Yogurt is one of the best-known sources of probiotics, containing strains of friendly bacteria such as lactic acid bacteria and bifidobacteria. Other fermented dairy products, such as kefir, buttermilk, and some soft cheeses like Gouda, also contain beneficial bacteria and yeast.
For those who are dairy-free or vegan, there are plant-based sources of probiotics. Tempeh, made from fermented soybeans, is high in protein and good bacteria. Fermented vegetables, such as sauerkraut and miso, are also excellent sources of gut-friendly bacteria. Additionally, brined olives, prepared through a natural saltwater fermentation process, contain the gut-friendly bacteria Lactobacillus.
Consuming prebiotic foods alongside probiotics can be beneficial, as they feed the good bacteria already present in the gut. Prebiotic foods include asparagus, Jerusalem artichokes, bananas, oatmeal, legumes, red wine, honey, and maple syrup.
By incorporating these probiotic-rich foods into your diet, you can support the restoration of good intestinal bacteria and potentially reduce body odour.

Eat leafy greens like spinach, kale, and chard to neutralise odours
While body odour is common in most people, certain foods can make it worse. The apocrine sweat glands, which are found in places like the armpits, release sweat that is full of proteins. Bacteria on our skin feed on these proteins and release smelly acids.
To combat body odour, try eating leafy greens like spinach, kale, and chard. These vegetables are rich in nutrients and can help neutralise odours. They are also a good source of antioxidants, which can help reduce toxins in the body.
In addition to their deodorising properties, leafy greens offer a host of other health benefits. They are packed with vitamins and minerals, including iron, calcium, and vitamins A, C, and K. These nutrients are essential for maintaining overall health and can boost your energy levels and strengthen your immune system.
When incorporating more leafy greens into your diet, try adding them to salads, smoothies, or juices. You can also lightly steam or sauté them to retain their nutritional value. If you're not a fan of the taste, try disguising them in soups or casseroles, or even blending them into a fresh green juice or smoothie.
While increasing your intake of leafy greens can be beneficial, it's important to note that cruciferous vegetables, such as broccoli, cabbage, and cauliflower, have been associated with bad body odour. This is due to the presence of sulphur compounds, which can be broken down into odour-causing substances by the bacteria on the skin. Therefore, while leafy greens can be a helpful addition to your diet, it's worth monitoring your body's response to cruciferous vegetables and adjusting your intake accordingly.

Reduce alcohol consumption and stay hydrated to minimise bad breath
Alcohol consumption can lead to bad breath, as the odour comes from your lungs rather than your mouth. This makes it difficult to get rid of the smell. While there are temporary fixes such as cough drops, drinking coffee, or chewing gum, the only way to truly get rid of alcohol breath is to give your body time to metabolise and eliminate the alcohol.
Alcohol can also cause dehydration, which can lead to bad breath. Dehydration can cause a dry mouth, which provides an environment for bacteria that causes bad breath to thrive. Therefore, staying hydrated by drinking water periodically while consuming alcohol can help to prevent bad breath.
In addition to staying hydrated, maintaining good oral hygiene is important for reducing bad breath. This includes proper brushing, flossing, and tongue brushing.
To help your body process alcohol more efficiently, it is recommended to maintain a healthy diet, stay active, and drink plenty of water. Heavy drinking or binge drinking can not only lead to bad breath but can also be a sign of alcoholism.
While reducing alcohol consumption and staying hydrated can help minimise bad breath, it is also important to be mindful of other odour-inducing foods and drinks. For example, certain vegetables, meat, and sulfur-rich foods can cause foul-smelling compounds to be excreted through sweat glands or result in rotten egg-smelling flatulence.

Avoid high-carb foods, which are associated with less pleasant-smelling sweat
It is important to note that the food we consume can play a significant role in influencing how our sweat smells. According to research, males who had a healthy diet rich in fruits and vegetables had better-smelling sweat, regardless of the amount they perspired. On the other hand, self-reported data revealed that a high-carbohydrate diet was associated with less pleasant-smelling sweat.
If you are keen on reducing body odour, it is advisable to avoid high-carb foods. This is because high-carbohydrate intake has been linked to stronger and less pleasant-smelling sweat. While the exact mechanism behind this phenomenon is not fully understood, it is believed that certain compounds in high-carb foods may be excreted through sweat glands, contributing to an unpleasant odour.
Some examples of high-carb foods that you may want to consume in moderation include bread, pasta, rice, potatoes, and sugar. These foods are rich in carbohydrates, which can provide energy for the body, but they may also impact the smell of your sweat. Therefore, if you are concerned about body odour, it is recommended to limit your intake of these high-carbohydrate foods.
Additionally, it is worth noting that certain spices, such as cumin, can also lead to an odd body odour. This is because the compounds in these spices can be excreted through the pores, resulting in an unusual smell. Similarly, strong-smelling foods like garlic, onion, leeks, and chives contain sulfur compounds that can contribute to body odour. These foods can give rise to what is commonly known as "garlic sweat," where the odour of the spices and vegetables can be detected through the pores.
