Candida overgrowth is a common issue that many people face, often manifesting as recurrent vaginal yeast infections, persistent fatigue, digestive issues, mood disturbances, and skin problems. Addressing this overgrowth often involves dietary changes, and one of the most debated topics is whether or not mushrooms should be included in a Candida diet. This article aims to clarify the role of mushrooms and other fungi in relation to Candida overgrowth, providing a comprehensive guide to help you make informed dietary choices.
Understanding Candida Overgrowth
Candida yeasts are naturally present in the body, residing on the skin, in the mouth, and in the gut. They are generally harmless, but when the body's defenses are weakened, they can cause infections. Candida albicans is the most common culprit behind these infections. Several factors can contribute to Candida overgrowth, including:
- Antibiotic use: Antibiotics can disrupt the balance of bacteria in the gut, allowing Candida to thrive.
- Diet: A diet high in sugar and refined carbohydrates can feed Candida and promote its growth.
- Lifestyle: Chronic stress and excessive alcohol consumption can weaken the immune system, leading to an imbalance in the gut microbiome.
- Increased estrogen levels: Higher estrogen levels, a comprised immune system, and chronic stress are risk factors of developing a Candida overgrowth.
Candida overgrowth can manifest in various symptoms, such as:
- Brain fog: Candida produces acetaldehyde, a neurotoxin that can impair cognitive function.
- Recurrent sinus infections: Chronic sinus infections are often fungal in nature.
- Joint pain: Candida produces uric acid, which can lead to joint pain.
- Skin issues: Leaky gut, often associated with Candida overgrowth, can allow yeast to enter the bloodstream and cause skin problems like acne, eczema, or psoriasis.
- Low mood: Candida overgrowth can negatively impact the gut bacteria that produce neurochemicals essential for regulating mood.
The Candida Diet: Principles and Guidelines
The Candida diet aims to starve Candida by eliminating its primary food sources. The main principles of the diet include avoiding:
- Sugar: All forms of processed sugar, including white or brown sugar, maple syrup, honey, agave, brown rice syrup, and high fructose corn syrup.
- Grains: Refined carbohydrates like white flour and white rice, which break down into simple sugars.
- Alcohol: Alcoholic beverages, as they are fermented using yeast.
- Fermented foods: Foods like cheese, especially moldy varieties such as brie and camembert.
- Dairy: Dairy products, which can be problematic for some individuals.
A typical Candida diet focuses on consuming:

- Healthy proteins: Lean meats, poultry, fish, eggs, and plant-based protein sources.
- Healthy fats: Unrefined, cold-pressed oils like olive oil, coconut oil, and flaxseed oil.
- Non-starchy vegetables: Especially dark leafy greens like spinach, cabbage, kale, and collards. Root vegetables like carrots and potatoes should be eaten in moderation due to their carbohydrate content.
- Limited fruit: 1-2 servings of fresh fruit per day to provide fiber, vitamins, and minerals.
- Hydration: Staying well-hydrated is crucial.
The Great Debate: Mushrooms and Candida
One of the most significant sources of confusion regarding the Candida diet is whether or not to consume fungi, specifically mushrooms.
Candida's Food Source
Candida primarily feeds on sugar and refined carbohydrates. Mushrooms and molds do not fall into either of these categories, meaning they do not directly provide Candida with the raw materials it needs to grow and spread.
Beneficial Properties of Mushrooms
Many mushrooms possess immunostimulatory properties, which can be beneficial for individuals dealing with Candida overgrowth. Mushrooms like agaricus blazei, coriolus versicolor, Shiitake, Maiitake, and Reishi are prized in Chinese and Western herbal medicine for their immune-supporting capabilities.
Candida sufferers often have compromised immune systems, and these immune-supportive mushrooms can help boost their immune function. Additionally, mushroom-derived supplements like Active Hexose Correlated Compound (AHCC) have been shown to enhance the immune system.
The Case Against Molds
While mushrooms can be beneficial, molds are a different matter. Molds often produce mycotoxins, which can be irritating to the gut and damage its lining. This can make the gut more porous and susceptible to overgrowth by microorganisms like Candida.

Some individuals may also be allergic to certain types of mold, triggering allergy-like symptoms such as sneezing, coughing, itchy skin, and digestive upset.
Guidelines for Consuming Mushrooms
- Choose Safe Mushrooms: Mushrooms can be a healthy part of a Candida diet, especially those with immune-stimulatory properties.
- Avoid Moldy Mushrooms: If you notice any mold growing on your mushrooms, it is best to discard them.
- Forage Carefully: If you are foraging for mushrooms, ensure you can identify poisonous varieties.
The Role of Diet in Gut Health and Candida Control
The gut microbiota plays a crucial role in overall health, including protection against pathogens, nutrient absorption, and immune function. An unhealthy diet, particularly a Western diet high in fat and sugar and low in vegetable fiber, can lead to gut dysbiosis and Candida overgrowth.
The Impact of Western Diets
Western diets are associated with changes in the gut microbiota that promote intestinal inflammation. These diets often lead to a decrease in beneficial bacteria like Bacteroidetes and an increase in harmful bacteria like Firmicutes and Proteobacteria. This imbalance can increase intestinal permeability, allowing toxins to enter the bloodstream and trigger inflammation.
The Benefits of Whole Plant Foods
A diet rich in whole plant foods, such as vegetables, fruits, and whole grains, can improve gut health and reduce the risk of Candida overgrowth. Whole plant foods contain fermentable dietary fiber, which the gut microbiota converts into short-chain fatty acids (SCFAs). SCFAs have anti-inflammatory, antioxidant, and anticancer properties.
Additional Lifestyle Factors
In addition to diet, other lifestyle factors can impact gut health and Candida overgrowth:

- Smoking: Contributes to gut dysbiosis and inflammatory pathogenesis.
- Excessive alcohol consumption: Weakens the immune system and disrupts the gut microbiome.
- Lack of physical activity: Associated with gut dysbiosis.
- Prolonged use of antibiotics: Disrupts the balance of bacteria in the gut.
- Chronic psychological stress: Weakens the immune system and contributes to gut imbalance.
Other Diet Tips to Fight Candida Infections
Besides the general guidelines of the Candida diet, here are some specific foods and dietary changes that may help fight Candida infections:
1. Coconut Oil
Coconut oil is rich in lauric acid, a saturated fatty acid with potent antimicrobial and antifungal effects. Test-tube studies suggest that lauric acid is very effective against Candida yeasts. Using coconut oil as a mouthwash (oil pulling) may help curb thrush, or Candida infections in the mouth.
2. Probiotics
Probiotics are live bacteria that can help restore the balance of beneficial bacteria in the gut. They compete with Candida yeasts for space and nutrients, protecting against infections. Probiotics can be found in fermented foods like yogurt with active cultures or taken as supplements.
3. A Low-Sugar Diet
Candida yeasts thrive in high-sugar environments. Reducing your sugar intake can help slow their growth. 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.
4. Garlic
Garlic contains allicin, a substance with strong antifungal properties. Allicin seems to fight Candida yeasts effectively. Spicing up your food with garlic is safe and healthy and might work well alongside conventional Candida treatments.
5. Curcumin
Curcumin, a component of turmeric, may kill Candida yeasts or reduce their growth. However, human studies are needed to confirm these effects.
Reishi Mushrooms and Candida
Reishi mushrooms, also known as Ganoderma lucidum, have gained popularity for their potential health benefits, including immune support and anti-inflammatory properties.
Health Benefits of Reishi Mushrooms
- Immune system support: Reishi mushrooms can trigger immune cells to mature into macrophages, which engulf and destroy pathogens like Candida albicans. They can also increase the activity of receptors on the surface of cells, helping the immune system recognize and destroy infectious invaders.
- Reduces inflammation: Reishi is a powerful antioxidant that can help combat free radical damage and reduce chronic inflammation.
- Liver health: Reishi supports and protects the liver, which is essential for processing Candida metabolites like acetaldehyde and gliotoxin.
- Cancer-fighting properties: Reishi contains ganoderic acid, which has demonstrated the ability to impede the growth of cancer.
Dosage and Side Effects
The dosage of Ganoderma lucidum depends on age, health, conditions, and the form of the supplement. Common side effects may include mouth, throat, and nasal dryness, itchiness and rash, stomach pain, dizziness, and headache. It is essential to consult with a healthcare provider before taking reishi, especially if you have a bleeding disorder, low blood pressure, are pregnant or breastfeeding, or have an autoimmune disorder.
Other Natural Supplements That Can Boost Immunity
- Burdock (Arctium Lappa): Enhances immunity and fights chronic inflammation. It has a history of use for fungal infections.
- Astragalus (Astragalus Membranaceus): Scavenges free radicals and reduces chronic inflammation.
- Ashwagandha (Withania Somnifera): Treats chronic inflammation, boosts the immune system, and has anti-fungal properties.
