Alcohol: Well, looks like there's one more demerit to drinking alcohol. When you consume alcohol like tequila shots, the alcohol gets absorbed by your body and is then metabolised into acetate or acetic acid which can be secreted into your sweat. That acetic sweat is then metabolised by skin bacteria which can cause body odour.

Beetroots are rich in iron which means they're extremely good for your blood, however, they also contain methyl which means they pack a pungent smell. Methyl breaks down in your digestive system to create a compound called trimethylamine or TMA. This compound is then released onto your skin and ends up creating a fishy smell.

You may think that chewing gum could help with your odour problems and not make them worse, but we say you should think again. When you chew gum, it causes you to ingest more air and this air builds up in your stomach, and of course, it comes out the other end.

Coffee may help you feel energised and active, but it can also cause your sweat glands to get activated which will eventually cause body odour. In fact, coffee is also highly acidic and so it instantly dries up your mouth. This then leads to bad breath.

When you consume dairy products like milk, yoghurt, cheese etc, it causes lipids to be secreted in your sweat. These lipids are then digested by bacteria on your skin which leads to the production of gasses. So, while you may enjoy consuming dairy products, maybe you should limit their intake.

Broccoli, cauliflower, and the rest of the cruciferous vegetables, milk and eggs can all cause body odour. They contain sulphur which by itself smells like rotten eggs which means eating these products may increase the availability of sulphur to skin bacteria. This allows the bacteria to create more sulphur containing compounds which may lead to unpleasant body odour.

Garlic and onions contain a high concentration of Volatile organic compounds (VOCs) which can give you "garlic sweat". These foods also tend to contain sulphur much like the aforementioned food items. So, not only can garlic cause odour to come from your mouth, the smell can also seep into your pores causing foul body odour.

While we already know that fish causes its own smell when it's out of the water, as per research it can also alter the smell in some people with a particular genetic condition. Trimethylaminuria is the body’s inability to break down a foul-smelling compound. This means that eating fish can cause an all-over fish smell in people who have this genetic condition.

You can add red meat to the list of smell-inducing, sulphur-rich foods. A study also suggests that eating meat might be affecting your sweat. In the study, researchers put a few people on vegetarian and non-vegetarian diets for two weeks. They collected their underarm sweat which was then analysed. It turned out that the sweat of those on vegetarian diets was less pungent as compared to those on the non-veg diet.
