5 Diet Tips to Fight Candida Yeast Infections

Candida yeasts are microscopic fungi found around the skin, mouth, or gut (2Trusted Source).

They’re usually harmless but may cause infections when your body’s defenses are weakened.

Plants have their own defenses against yeasts and other fungi, and some produce compounds that are toxic to fungi.

A good example is lauric acid, a saturated fatty acid widely studied for its antimicrobial and antifungal effects.

Coconut oil is almost 50% lauric acid. This makes it one of the richest dietary sources of this compound, which rarely occurs in high amounts in food.

Test-tube studies suggest that lauric acid is very effective against Candida yeasts. As such, coconut oil may have similar effects (3Trusted Source, 4Trusted Source, 5Trusted Source).

For this reason, using coconut oil as mouthwash — a method known as oil pulling — may curb thrush, or Candida infections in your mouth.

Keep in mind that human studies are needed to confirm these benefits.

SUMMARY One of the main components of
coconut oil, lauric acid, may fight Candida infections. However, human
research is needed to confirm these effects.

Several factors may make some people more prone to Candida infections, including diabetes and a weakened or suppressed immune system.

Antibiotics may also increase your risk, as strong dosages sometimes kill a portion of the beneficial bacteria in your gut (1Trusted Source, 2Trusted Source).

These bacteria are a part of your body’s natural defenses against Candida yeasts. They protect against infections by competing with them for space and nutrients (6Trusted Source).

Probiotics may help restore these populations of beneficial bacteria (7Trusted Source).

Probiotics are live bacteria often found in fermented foods, such as yogurt with active cultures. They can also be taken in supplements.

Studies suggest that probiotics may fight Candida infections (8Trusted Source).

A 12-week study in 215 older adults showed that taking lozenges containing 2 strains of the probiotic Lactobacillus reuteri significantly reduced the amount of Candida yeasts in their mouths (9Trusted Source).

In another study in 65 people with thrush, taking probiotics significantly improved the effectiveness of a conventional antifungal treatment (10Trusted Source).

Probiotics may also reduce the growth of Candida in your gut, and some evidence indicates that vaginal capsules with Lactobacillus probiotics may combat vaginal yeast infections (11Trusted Source, 12Trusted Source, 13Trusted Source, 14Trusted Source).

SUMMARY Probiotics may reduce Candida
growth and protect against infections in your mouth and gut. Vaginal capsules
may also be effective.

Yeasts grow faster when sugar is readily available in their environment (15Trusted Source, 16Trusted Source, 17Trusted Source).

In fact, high levels of sugar in your bloodstream increase your risk of Candida infections (1Trusted Source, 18Trusted Source, 19Trusted Source, 20Trusted Source).

In one study, sugar increased Candida growth in the digestive system of mice with weakened immune systems (21Trusted Source).

In a human study, rinsing with dissolved sugar (sucrose) has been linked to increased infections and higher yeast counts in the mouth (22Trusted Source).

On the other hand, another human study found that a high-sugar diet did not affect Candida growth in the mouth or digestive system (23Trusted Source).

However, human studies are limited, and more research is needed (24Trusted Source).

Even if a low-sugar diet may not always be effective against yeasts, eliminating added sugar from your diet will improve your health in many other ways.

SUMMARY Candida yeasts favor high-sugar
environments. However, there’s limited evidence for the benefits of a low-sugar
diet against Candida infections.

Garlic is another plant food with strong antifungal properties. This is partly due to allicin, a substance that forms when fresh garlic is crushed or damaged (25Trusted Source).

When given to mice in high amounts, allicin seems to fight Candida yeasts at a slightly less effective level than the antifungal drug fluconazole (26Trusted Source).

Test-tube research also indicates that garlic extract may reduce yeasts’ ability to attach to the cells lining your mouth (27Trusted Source).

However, garlic provides only tiny amounts of allicin, whereas most studies use high doses.

One 14-day study in women found that taking garlic supplements in capsules did not affect vaginal yeast infections (28Trusted Source).

Overall, more clinical trials are needed to determine whether eating garlic has any treatment value in humans.

Nevertheless, spicing up your food with garlic is safe and healthy. It might also work well alongside conventional Candida treatments.

Keep in mind that using raw garlic in sensitive areas, such as your mouth, can be harmful and cause severe chemical burns (29Trusted Source, 30Trusted Source).

SUMMARY Allicin in garlic acts against Candida.
Still, it’s unclear whether eating garlic affects yeast infections.

Curcumin is one of the main active components of turmeric, a popular Indian spice (31Trusted Source).

Test-tube research indicates that curcumin may kill Candida yeasts — or at least reduce their growth (32Trusted Source, 33Trusted Source, 34Trusted Source, 35Trusted Source).

Another study suggested that curcumin may reduce yeasts’ ability to attach to cells from the mouths of people with HIV. In fact, curcumin was more effective than fluconazole, an antifungal drug (36Trusted Source).

Nonetheless, studies are limited to test tubes. It’s unclear whether curcumin supplements have effects in humans.

SUMMARY Curcumin, one of the active components of turmeric,
may kill Candida yeasts. However, human studies are needed.

If you think you have a yeast infection, see your medical practitioner for an antifungal medication.

If you tend to get a lot of these infections, following a healthy diet or taking supplements like probiotics may help.

On their own, these diet strategies are far from being an effective treatment. But as a preventative measure, or alongside medication, they could make a difference.
