A woman's diet could influence how her intimate area smells, with everyday ingredients such as garlic, onions, asparagus and coffee potentially contributing to temporary changes in body odour, according to a gynaecologist. Dr Kate McLean, an obstetrician-gynaecologist and chief medical officer at women's health company Evvy, has explained how certain foods can affect the scent around the vagina and vulva.
Her comments follow women sharing personal experiences of noticing changes in their intimate smell after eating particular foods. The discussion has also brought attention to the idea of a 'vagina diet', although the medical expert stressed that women do not need to restrict nutritious foods to maintain a healthy vaginal scent.
Women Link Certain Foods to Vaginal Odour
Women have reported noticing changes in their vaginal odour after eating certain foods, including raw onions, garlic, seafood and dairy products, prompting questions about the possible relationship between diet and intimate scent. One woman described noticing a difference after regularly eating raw onions, particularly when adding them to burgers and fajitas. She also reported changes in her intimate smell after eating shellfish, including prawns and crab.
Other women shared similar experiences involving garlic, seafood and coffee, with some reporting that the changes became noticeable the following day. These reports have drawn attention to how everyday dietary choices may influence body odour, although individual experiences do not establish a direct link between specific foods and changes in vaginal scent.
How Garlic and Other Foods May Affect Vaginal Odour
Dr McLean explained that dietary habits can contribute to variations in vaginal and vulvar odour. She said: 'People are often surprised by how much vaginal and vulvar odour can vary, including changes related to what they eat.'
The gynaecologist explained that the scent around the intimate area can be influenced by sweat, urine, vaginal discharge and other bodily secretions, rather than originating solely from inside the vagina. Garlic is among the foods that may affect body odour. During digestion, it produces sulphur-containing compounds that enter the bloodstream and can eventually be released through the breath and sweat.
Dr McLean noted that raw garlic may have a stronger effect than cooked garlic because heat breaks down some of its compounds. Any noticeable changes may appear within a few hours and typically subside within 24 to 48 hours.
Other foods that may influence body odour include onions, asparagus and cruciferous vegetables such as broccoli, cauliflower and cabbage, which contain sulphur compounds. Spicy foods and coffee may also increase sweating, potentially making existing body odours more noticeable. Alcohol can change scent as the body breaks it down and releases by-products through breath and sweat.
Can Pineapple Make Your Vagina Smell Sweeter?
Pineapple is frequently discussed in conversations about intimate hygiene, particularly the belief that eating the fruit can make vaginal odour or taste sweeter. Dr McLean said there is no good evidence that pineapple or certain other fruits can change vaginal scent.
She also emphasised that a healthy vagina is not supposed to smell like flowers. Natural vaginal odours can vary from person to person, with earthy, tangy, musky and slightly sweet scents all potentially being normal. Changes can also occur throughout the menstrual cycle, meaning that a different smell does not automatically indicate a health problem.
When Vaginal Odour Signals Infection
Although temporary changes in intimate odour can be associated with food and other everyday factors, persistent or unusually strong smells should not automatically be attributed to diet. Dr McLean advised women to seek medical advice if an unusual odour lasts for more than a couple of days, becomes particularly strong or fishy, or is accompanied by other symptoms.
These may include unusual vaginal discharge, itching, burning, irritation or pain. One possible explanation is bacterial vaginosis (BV), a common condition caused by an imbalance in the bacteria naturally found in the vagina. It can produce thin, greyish-white discharge with a noticeable fishy smell, particularly after sex.
The NHS also advises women to seek medical guidance if their vaginal discharge changes in colour, smell or texture, or if they experience itching, soreness or pain when urinating. Such symptoms should be assessed by a healthcare professional rather than treated by changing dietary habits alone.
Gynaecologist Warns Against Overwashing
Dr McLean also cautioned against attempting to eliminate unexpected vaginal smells through excessive washing or aggressive cleaning. She explained that if the change is related to food, the body needs time to metabolise and clear the compounds responsible. Additional cleaning will not speed up that process.
The vagina is naturally self-cleaning, while normal vaginal discharge helps keep it clean and protected. The NHS recommends gently washing the external genital area with warm water and mild, non-perfumed soap. It also advises against using scented hygiene products, vaginal deodorants and internal washes, which can cause irritation or disrupt the natural balance.
