Candida is a common fungus naturally present in the human body, primarily in areas like the mouth, skin, digestive tract, and vagina. While generally harmless, an overgrowth of Candida can lead to infections. The candida diet is a strict dietary regimen designed to alleviate symptoms of candida infections by limiting foods and drinks that may promote Candida growth. This typically involves excluding alcohol, caffeine, and foods high in sugar and gluten. However, it's important to note that the effectiveness of the candida diet is not strongly supported by scientific evidence.
Understanding Candida and Candidiasis
There are over 150 known Candida species, many of which naturally occur in the body and aid in digestion and nutrient absorption. Despite the variety, only about 15 species can cause infection, with Candida albicans being the most common culprit.
Candidiasis, the infection resulting from Candida overgrowth, can manifest in various forms:
- Oral Thrush: Characterized by white patches inside the mouth, inflammation, and soreness of the throat, pain while eating or swallowing, and persistent dryness of the mouth.
- Vaginal Candidiasis (Yeast Infection): Symptoms include itching or soreness of the vagina and vulva, pain when urinating or during intercourse, and a thick, white vaginal discharge resembling cottage cheese.
- Systemic Candidiasis: In severe cases, Candida can enter the bloodstream, leading to a life-threatening invasive infection with symptoms like fever and chills.
Some practitioners also recognize candida overgrowth as the source of a number of health symptoms that can be overcome with dietary changes. “Symptoms of candidiasis can be widespread, from bloating and distention to bowel irregularities, chronic fatigue, cystic acne and other skin rashes, and brain fog".
Risk Factors for Candida Overgrowth
Several factors can increase the risk of Candida infection:

- Diet High in Refined Carbs and Sugar: Excessive sugar intake may worsen candida infections, particularly in individuals with weakened immune systems.
- High Alcohol Consumption: Alcohol is discouraged to support healthy lifestyle practices and prevent dietary cheating.
- Elevated Stress Levels: Stress management techniques like meditation may be beneficial.
- Imbalance in Microbiota: A disruption in the balance of gut bacteria can create an environment conducive to Candida overgrowth.
- Improper Use of Catheters: Medical devices like catheters can introduce Candida into the body.
- Birth Control Pills or Antibiotics: These medications can alter the body's natural flora, potentially leading to Candida overgrowth.
- Diabetes Mellitus Diagnosis: People with diabetes and poorly managed blood sugar levels are at greater risk of developing yeast infections.
- Weak Immune System: A compromised immune system is less effective at controlling Candida growth.
The Candida Diet: Principles and Claims
The candida diet aims to reduce inflammation and incorporate wholesome foods that may benefit the gut and reduce the risk of candida over time. Proponents believe it kills off candida overgrowth by eliminating sugar, gluten, alcohol, and some dairy products, while focusing on organic, low-sugar, high-quality produce, meats, and fats.
The diet generally removes all sources of flour, sugar, and yeast from your diet and encourages lean proteins, nonstarchy vegetables, and healthy fats, as well as several supplements to encourage the process.
However, most of these dietary restrictions are not supported by strong scientific evidence. For example, the exclusion of gluten is based on claims that it may damage the intestinal lining, but there is no evidence of this in people without gluten intolerance (celiac disease). Similarly, while lactose (milk sugar) may theoretically stimulate candida growth by increasing acidity in the mouth, this hasn't been confirmed.
Foods to Include in the Candida Diet
The candida diet emphasizes whole, unprocessed foods. Here's a breakdown of what to focus on:
- Low-Sugar Fruits: Lemon, limes, and berries (in small amounts) are permitted.
- Non-Starchy Vegetables: Asparagus, Brussels sprouts, cabbage, broccoli, kale, celery, cucumber, eggplant, onion, spinach, zucchini, tomatoes, and rutabaga are encouraged, preferably raw or steamed.
- Gluten-Free Grains: Millet, quinoa, oat bran, and buckwheat can be incorporated.
- High-Quality Protein: Chicken, eggs, salmon, turkey, and sardines are good choices, ideally organic, pasture-raised, and wild-caught.
- Healthy Fats: Avocado, olives, unrefined coconut oil, flax oil, extra-virgin olive oil, and sesame oil are recommended.
- Certain Dairy Products: Butter, ghee, organic kefir, or plain yogurt can be included.
- Nuts and Seeds Low in Mold: Almonds, sunflower seeds, coconut, and flaxseed are preferred.
- Herbs and Spices: Black pepper, salt, cinnamon, dill, garlic, ginger, oregano, rosemary, paprika, turmeric, and thyme are allowed.
- Condiments: Apple cider vinegar, coconut aminos, and sauerkraut can be used.
- No-Sugar Sweeteners: Stevia, erythritol, and xylitol are permitted as sugar substitutes.
- Non-Caffeinated Beverages: Herbal teas, chicory coffee, filtered water, homemade almond milk, coconut milk (without additives), and water infused with lemon or lime are good options.

Potential Benefits and Downsides of the Candida Diet
Despite the lack of strong evidence supporting its effectiveness against candida infections, the candida diet may offer some potential benefits due to its emphasis on healthy foods. The diet consists of whole foods and focuses on removing sugary foods, which have been linked to various health problems like obesity, diabetes, heart disease, and metabolic syndrome. A diet such as this can be beneficial for anyone - even those without candida overgrowth.
One 3-month study in 120 people with intestinal candida overgrowth showed that dietary changes had significantly reduced the numbers of candida yeasts in stool, compared to those who didn’t change their diet.
However, the diet's strictness can be a major pitfall. The elimination of sugar, gluten, most fruits, starchy vegetables, some meats, nuts, seeds, alcohol, and caffeine requires significant adjustments and may be difficult to maintain, especially for those on a budget or who don't enjoy cooking and meal planning.
Candida Cleanse: A Preliminary Step?
Before starting the candida diet, some proponents recommend a candida cleanse, a short-term diet believed to alleviate stress on the digestive tract and release toxins from the body. While no studies support the benefits of a candida cleanse, it might help get you into the mindset for the candida diet.

Common cleanse methods include:
- Drinking only fluids, such as lemon water or bone broth.
- Eating mainly vegetables, such as salads and steamed vegetables, alongside a small amount of protein throughout the day.
Some people may experience negative symptoms while starting a cleanse, such as fatigue, headaches, mood swings, or changes in sleep patterns. The candida cleanse should not last more than a few days.
Important Considerations Before Starting the Candida Diet
- Start Slowly: Instead of removing everything at once, focus on eliminating one item at a time to ease the transition.
- Short-Term Approach: The candida diet is intended for short-term use until symptoms improve, not as a long-term replacement for a balanced diet.
- Work with a Healthcare Provider: Consult with a healthcare professional to ensure adequate nutrient intake and address any underlying health conditions.
Common Misconceptions About the Candida Diet
- Candidiasis Can Be Cured Through Diet Alone: Medical treatment, such as antifungal medication, is typically necessary to cure candidiasis. Diet may play a supportive role in overall gut health, but it’s not a stand-alone cure.
- Following the Candida Diet Will Cure My Yeast Infection: Dietary interventions alone are generally ineffective for treating active vaginal yeast infections. Oral or topical antifungal medications are usually required.
- Eliminating Sugar Will Help Me Treat Candidiasis: While excessive sugar intake may increase the risk of developing a yeast infection, simply avoiding sugar in the diet won’t "starve" any candida already in your body.
- Dairy Causes Candida Overgrowth: For most people, dairy does not feed candida. Unless someone has a milk allergy, lactose intolerance, or notices that dairy worsens symptoms, dairy can be part of a balanced diet, even when managing candida with medical treatment.
- You Shouldn’t Eat Fermented Foods if You Have Candida Overgrowth: Fermented foods like yogurt, kefir, sauerkraut, and kimchi contain probiotics that may help restore a healthy balance of bacteria in the gut.
