What we eat and drink can affect how our body smells. Various studies at universities around the world have shown that what we put into our bodies changes our bodily smells. Researchers say that each of us has a unique pattern of bodily odours. This is similar to the uniqueness of a fingerprint. Lina Begdache, an assistant professor of health and wellness at the State University of New York, said the odours our body gives off come from two areas. One is the stomach, which is full of bacteria. When these bacteria break down food, gases and chemicals are released through our breath. Some of these gases can give us bad breath. The second area is the skin. Food can change the smell of bacteria on our skin when we sweat.

Researchers say the foods that give off the strongest smells contain sulphur. This chemical often creates a "bad-egg smell". Vegetables like broccoli, cabbage, and cauliflower contain a lot of sulphur. Another food that affects how smelly we are is garlic. This is well known for making our breath smell. However, researchers say it can make our armpit sweat smell nicer. Scientists also say drinks affect body odours. Alcohol can lead to stronger, unattractive bodily smells and bad breath. Caffeine in coffee and tea creates chemicals that produce sweat in areas like our armpits and groin. If we want to smell a little sweeter, we should eat oranges, apples, parsley, and yoghurt, and drink water and green tea.
