We all have a unique natural scent that makes us who we are. Just like a fingerprint, our body odour is influenced by many things – from our hormones and hygiene to our diet and daily habits. While genetics play a big role, what we eat can also change the way we smell, both through our breath and our skin. Surprisingly, certain foods can make us smell fresher and even more attractive to others.
Let’s explore how the food we eat affects our scent – and which foods might help you smell your best.
How Food Changes Body Odour
Our diet affects body smell in two main ways – through the gut and the skin.
When food is digested, bacteria in the gut break it down, releasing gases and compounds that can escape through the mouth or sweat glands. These chemical reactions can make our breath or sweat smell different depending on what we eat.
Some foods contain strong-smelling compounds like Sulphur, which are responsible for odours such as garlic breath or the scent that follows eating onions or cabbage. These compounds are absorbed into the bloodstream and eventually released through the skin and breath.
The Surprising Power of Fruits and Vegetables
While some vegetables like broccoli, cabbage, or cauliflower are packed with Sulphur, studies suggest that people who eat a diet rich in fruits and vegetables tend to smell fresher and more pleasant.
Fruits and colorful vegetables are rich in carotenoids — natural pigments found in foods like carrots, tomatoes, papayas, and pumpkins. These antioxidants not only give the skin a healthy glow but also improve how your natural scent is perceived. People who eat more fruits and vegetables are often described as smelling sweeter and cleaner compared to those who eat mostly processed foods or carbohydrates.
Interestingly, even though garlic can make your breath stronger, research suggests it might make your body scent more attractive. Garlic has natural antioxidant and antibacterial properties that can improve body chemistry and reduce unpleasant odour from sweat.
Meat, Fish, and Protein Effects
Foods high in animal protein such as meat and fish can also influence the way your body smells. When proteins are broken down, they release amino acids and fats that interact with bacteria on your skin. This can cause a stronger or more intense odour.
Some studies have shown that people who avoid meat are often rated as having more pleasant and lighter body scents. This doesn’t mean you need to stop eating meat altogether – but reducing your intake may help balance your natural scent.
Fish and beans contain a compound called trimethylamine, which has a powerful smell. In rare cases, some people’s bodies cannot fully process this compound, leading to what’s known as “fish odour syndrome.” However, this is extremely uncommon.
Alcohol, Coffee, and Strong Drinks
What you drink can also affect how you smell. Alcohol, especially when consumed frequently, can leave behind a noticeable scent because your body releases it through both your breath and your sweat. When alcohol is processed in the liver, it forms a compound called acetaldehyde, which carries a stale smell that can linger for hours.
Coffee and caffeinated drinks can also impact your body odour. Caffeine can increase sweating, especially in the armpits and groin areas, giving bacteria more opportunity to thrive. This can sometimes lead to stronger or sour smelling sweat if you don’t stay hydrated.
Fasting and Its Unusual Effect
Fasting can change your body’s natural scent too. When your body goes without food for a while, it burns fat for energy, releasing certain compounds known as ketones. These can sometimes cause your sweat to smell slightly different – yet, surprisingly, some studies found that people who fasted briefly ware rated as having more attractive natural scents. However, fasting may make your breath smell less pleasant due to changes in digestion and mouth bacteria.
Your Scent Reflects Your Health
Our body odour is more than just a smell – it’s a reflection of our internal health and diet. A balanced diet rich in fruits, vegetables, nuts, and whole foods can help you maintain a clean, fresh scent naturally. Processed foods, alcohol, and heavy meats can lead to stronger or less pleasant smells.
Smelling good starts from within. Eating right, drinking plenty of water, and maintaining good hygiene can make your natural scent more appealing – no expensive perfumes required.
