Garlic, onions, some vegetables and spices can temporarily change the odor of sweat, including in the intimate area. However, a sharp or unusual vaginal odor should not automatically be attributed to diet, especially if it is accompanied by itching, pain, or changes in discharge.

Midwife-gynecologist Kate McLean explains that the smell in the intimate area depends on several factors. Among them are the composition of the vaginal microbiome, natural discharge, the activity of sweat glands on the skin of the vulva, and substances excreted in urine.
Some compounds from food, after digestion, enter the bloodstream and are later excreted through breath and sweat. That is why after certain foods body odor sometimes changes, including in the groin area. At the same time, the smell of sweat on the skin and the smell of vaginal discharge are not the same.
Garlic and onions can influence sweat odor through sulfur-containing compounds. During digestion of these foods, substances are formed that are subsequently eliminated from the body and can give sweat its characteristic smell.
Similar temporary changes are possible after consuming broccoli, cauliflower, and cabbage (both red and white), as well as asparagus. These vegetables also contain sulfur-containing compounds, although the degree of change depends on individual differences.
Hot spices can intensify sweating. In addition, certain aromatic compounds from food can affect sweat odor. Coffee and alcohol in some people can also increase sweating, making the natural body odor more noticeable.
According to specialists, diet-related changes can appear within several hours after eating and usually disappear within 24–48 hours. Their duration is influenced by sweating, fluid intake, clothing, and individual body characteristics.
A mild natural odor of the intimate area by itself is not a sign of disease. It may be slightly sour, musky, or earthy. The odor of vaginal discharge is also influenced by changes in the microbiome and hormonal fluctuations during the menstrual cycle.
The common claim that pineapple or other tropical fruits can make the intimate odor “sweet” does not have convincing scientific evidence.
If the odor changes after a meal, usually a normal shower, clean underwear, and time are sufficient. For care of the external intimate area, perfumed products are not necessary, and douching may disrupt the natural environment of the vagina.
Sweat and sebaceous glands are also located on the skin of the vulva. After physical activity or in hot weather, microorganisms on the skin break down components of sweat, causing the odor to become stronger. In such cases, a shower with warm water and changing underwear help.
A persistent sharp or strong fishy odor requires the attention of a gynecologist. It is especially important to see a doctor if unusual discharge, itching, burning, or pain during urination or sexual activity occur at the same time.
Do not delay seeking medical help if the odor change is accompanied by fever, pelvic pain, or a general decline in well-being. It is also advisable to consult a gynecologist if symptoms appeared after a change in sexual partner or recur after treatment.
