What we eat affects just about every part of our body—including the vagina. The vaginal microbiome, or flora, is a micro-ecosystem 1 in constant flux.

Its makeup changes throughout the menstrual cycle and in response to different lifestyle factors, but healthy bacteria, specifically Lactobacillus, are essential for keeping it in balance.

Certain foods may disrupt the vaginal microbiome, increasing your risk of vaginal infections like bacterial vaginosis (BV), candidiasis (yeast infection), and urinary tract infections (UTIs).

“Certain foods can cause vaginal infections due to their effects on hormonal balance, immune function, and the vaginal microbiome,” says Melanie Bone, MD, a consultant OBGYN and US Medical Director at Daye. “For example, foods high in sugar can promote the growth of yeast, while processed foods can disrupt the balance of vaginal flora.”

If you’re prone to vaginal infections, tweaking your diet may help. Here’s a look at little-known foods that might disrupt your vaginal microbiome and what you can do to prevent future vaginal infections.

Lesser-known foods that may cause vaginal infections

Here are some foods and drinks you may not know are affecting your vaginal microbiome.

Caffeine

This may come as a shock to coffee and energy drink lovers, but caffeine may affect your vaginal microbiome.

In addition, a 2022 study found that caffeine may cause yeast infections 6, specifically an overproduction of Candida albicans. Research shows that Candida albicans is the most prevalent fungus 7 in the body.

It is an opportunistic fungus that can lead to infections from pre-disposing factors, such as caffeine consumption.

Alcohol

While drinking alcohol in moderation shouldn’t have a significant impact on your vaginal health, excessive consumption may increase your risk of bacterial vaginosis, according to a 2021 study 8.

“Alcohol can disrupt the balance of vaginal flora and weaken the immune system, making it easier for infections like yeast and bacterial vaginosis to occur,” Dr. Bone explains.

Besides vaginal infections, a 2023 research study found that high alcohol consumption could decrease sexual stimulation, cause vaginal dryness, dyspareunia (painful sex), and difficulties reaching orgasm.

Fermented foods

However, eating too many fermented foods may cause more harm than good.

For example, if you overeat yogurt that contains added sugars, the sugars can cause yeast overgrowth in the vagina, potentially leading to infection.

Undercooked food

Be sure that any meat you eat is fully cooked, as you might expose yourself to a urinary tract infection (UTI).

If you consume undercooked ground beef, pork, lamb, steaks, and beef roast that hasn’t reached a safe internal temperature, you can develop E. coli infection.

According to an older review of studies 12, there is a strong association between food-borne bacteria like Escherichia coli (E. coli) and UTIs.

6 tips for preventing vaginal infections

Below are some ways you can adjust your diet to prevent vaginal infections:

Eat a balanced diet: “Maintaining a balanced diet rich in fruits, vegetables, whole grains, and lean proteins,” Dr. Bone says. “This will help your gut and your vaginal microbiome.”Eat a diet high in fiber: Research suggests that a fiber-rich diet may reduce your risk of BV 13. Dr. Bone recommends fiber supplements if you can’t consume many fiber-rich foods.Stay hydrated: “Water can help our bodies get rid of toxins,” Barret says. “Stay hydrated to promote a well-filtered body.”Drink herbal tea: Herbal teas contain the active ingredient polyphenol 14, which has many health benefits for the vaginal microbiome. “Ginger, chamomile, and peppermint tea may have anti-inflammatory and antimicrobial ingredients that help our bodies with overall health,” Barret says.Limit your caffeine intake: While you don’t have to give up caffeine altogether, try to reduce your caffeine intake. “Always have a glass of water alongside your caffeinated drink, and remember not to consume more than 200 milligrams (mg) of caffeine per day,” Dr. Bone says.Try vinegar-infused water: “Some studies show that consuming a spoonful of vinegar diluted in a glass of water before eating can lower your insulin spike 15,” Dr. Bone says. “This will help your body better deal with sugary foods.”

The takeaway

Your vaginal microbiome is prone to many infections from your dieting and lifestyle habits.

Research reveals caffeine, alcohol (in excessive amounts), and fermented and undercooked foods may increase your risk of developing common vaginal infections like bacterial vaginosis (BV), candidiasis (yeast infection), and urinary tract infections (UTIs).

You can lessen your chances of getting a vaginal infection by adjusting your diet to include healthier foods and beverages.

If dietary changes don’t improve your vaginal health, please seek medical advice from a healthcare provider.
