The Candida diet has gained popularity as a dietary approach to reduce or prevent Candida yeast infections. Proponents suggest that specific food choices can control Candida overgrowth in the body. However, it's crucial to approach this diet with a balanced perspective, considering the available scientific evidence and potential benefits.
Understanding Candida and Candidiasis
The genus Candida consists of over 100 different species of yeast that naturally reside on the skin and within the body, including the mouth, throat, gut, and vagina. In normal concentrations, Candida plays a role in promoting gut health, nutrient absorption, and digestion. Candidiasis, on the other hand, is a fungal infection that occurs when Candida proliferates excessively. Candidiasis can manifest in various forms, such as oral thrush (affecting the mouth), esophagitis (affecting the esophagus), and vaginal candidiasis (affecting the vagina).
Symptoms of Candidiasis
The symptoms of candidiasis vary depending on the location of the infection:
- Mouth, throat, or esophagus: White patches, inflammation and soreness, pain while eating or swallowing, persistent dry mouth.
- Vagina: Itching or soreness, pain when urinating or during intercourse, thick, white vaginal discharge resembling cottage cheese.
The Candida Diet: Principles and Rationale
The Candida diet aims to reduce the risk of Candida overgrowth by restricting foods and beverages that may promote yeast proliferation. The core principle involves limiting or avoiding sugar, gluten, alcohol, and certain dairy products. Instead, the diet emphasizes lean proteins, healthful fats, non-starchy vegetables, and probiotics, with the intention of minimizing inflammation and balancing gut bacteria.
Foods to Include
Those following the Candida diet typically incorporate these foods:

- Non-starchy vegetables: Broccoli, Brussels sprouts, kale, onions, tomatoes, and leafy greens.
- Low-sugar fruits: Citrus fruits, olives, and berries (in moderation).
- Lean proteins: Chicken, eggs, and fish, wild-caught salmon.
- Healthy fats: Avocado, coconut oil, extra virgin olive oil, flaxseed oil.
- Fermented foods: Sauerkraut, kimchi, and yogurt (with live active cultures).
- Gluten-free grains: Quinoa, oat bran, buckwheat, and rice.
- Low-mold nuts and seeds: Almonds, coconut, flaxseed, and sunflower seeds.
- Certain dairy products: Butter, ghee, kefir and yogurt (products that contain live active cultures).
- Natural sugar-free sweeteners: Stevia, monk fruit extract, erythritol, and xylitol.
Foods to Avoid
The Candida diet typically restricts the following foods:
- Starchy vegetables: Potatoes, corn, beans, and peas.
- High-sugar fruits: Bananas, mangoes, figs, and raisins.
- Certain meats: Processed meats and farm-raised fish.
- Grains containing gluten: Wheat, barley, and rye.
- Dairy products high in lactose: Milk and soft cheeses.
- Processed fats and oils: Canola oil, soybean oil, and margarine.
- Simple sugars and artificial sweeteners: Sucrose, aspartame, agave, maple syrup, corn syrup, and honey.
- Some types of nuts and seeds: Peanuts, pecans, pistachios, and cashews.
- Certain drinks: Caffeinated coffee and tea, sugar-sweetened beverages, and alcohol.
Scientific Evidence and Research
While the Candida diet's rationale seems plausible, the scientific evidence supporting its effectiveness remains limited. Some small studies have explored the influence of sugar and gluten on Candida growth. For instance, one test-tube study suggested that sugar alternatives might reduce Candida growth in the mouth. Another small study found an association between purified wheat product consumption and increased Candida growth.
However, these studies have limitations, and more robust research is needed to confirm the diet's efficacy. The complex and multifactorial nature of diet and lifestyle makes it challenging to isolate the specific effects of the Candida diet.
Potential Benefits and Considerations
Despite the lack of conclusive evidence, adopting a varied, nutrient-dense diet rich in fiber, healthy fats, and probiotics may promote gut health and potentially reduce the risk of gastrointestinal Candida overgrowth. Reducing sugar intake, a key component of the Candida diet, can benefit overall health for many individuals.
It's important to recognize that various factors can influence a person's risk of developing Candida overgrowth, including antibiotic use, a weakened immune system, and underlying medical conditions like diabetes or kidney failure. These factors make it challenging to predict how dietary changes will affect an individual's risk.

Strongest Candida Killers to Include in Your Diet
In addition to removing toxic and inflammatory foods, an anti-Candida diet focuses on increasing your intake of foods recognized as strong Candida killers, minimizing the growth of Candida.
- Coconut oil: Coconut oil is a great food to add to your anti-Candida diet because it naturally contains capric acid and lauric acid, which promote gut health. These anti-fungal fatty acids kill Candida overgrowth and replication by poking holes in its cell wall, which kills them off. Capric acid, otherwise known as caprylic acid, is fast and effective at eliminating Candida overgrowth, making it one of the strongest Candida killers.
- Apple cider vinegar: Apple cider vinegar is the one type of vinegar allowed on an anti-Candida diet. Most vinegar is made from alcohol or grains. Apple cider vinegar is sourced from apples or, more accurately, apple cider.
- Garlic: Garlic has a long history of being one of the strongest Candida killers. This herb contains allicin, a compound with natural antifungal properties that inhibit the growth and reproduction of Candida cells.
- Cruciferous vegetables: Cruciferous vegetables, such as broccoli, Brussels sprouts, arugula, cabbage, and radishes, are among the most powerful foods that kill Candida. They contain isothiocyanates, which are sulfur- and nitrogen-containing compounds that inhibit the growth of Candida.
- Olive, flax, avocado, and primrose oils: Olive, flax, avocado, and primrose oils contain polyphenols, which are free-radical fighters that can help your body fight Candida.
- Ginger: Ginger contains gingerols and shogaols. These inflammation-fighting, antifungal components of the ginger root support a healthy balance of bacteria to help eliminate Candida overgrowth.
- Cinnamon: Cinnamon is a natural spice that promotes a healthy inflammatory response, and it also exhibits antifungal properties. Similar to caprylic acid, cinnamon appears to damage yeast cells, killing them by causing them to eventually die off.
- Cloves: Cloves naturally contain eugenol, a powerful oil and the perfect addition to your anti-Candida diet. Clove oil possesses strong anti-fungal activity against opportunistic fungal pathogens such as Candida albicans.
- Lemons: Lemons are a well-known anti-fungal food that can kill Candida. Lemons are a known antioxidant food. Lemons primarily work by detoxing the liver as it fights off Candida.
- Wild-caught salmon: Wild-caught salmon is an excellent source of Omega-3 fatty acids, with powerful anti-fungal properties and supports a healthy inflammatory response. Omega-3s work together with your immune system to promote a healthy gut lining.
Foods to Avoid on an Anti-Candida Diet
- Sugar: Sugar especially affects Candida overgrowth as yeast feeds on sugar. That being said, you will want to cut out all sugar and sweeteners. This includes artificial sweeteners. The key here is avoiding not just the obvious sources such as sodas, candy, cakes, and cookies, but also the sugar lurking in unexpected places, including salad dressings, low-fat packaged foods and protein bars.
- Alcohol: It is particularly important to cut out beer and wine while getting your yeast in check. Wine is not only fermented (meaning it is made from yeast), it is also high in sugar. Beer, which is also fermented, contains gluten.
- Dried Fruit and Fruit Juice: Although some fruits such as berries can be part of an antioxidant-rich diet, they are high in sugar and still feed Candida. Dried fruit and fruit juice can be major culprits of yeast overgrowth. They may seem like healthy options, however, they are not.
- Gluten: It is recommended removing gluten completely from your diet, as it is highly inflammatory. It is also a grain, and your body breaks all grains down into simple sugars during digestion, which feeds Candida overgrowth. Even so-called gluten-free grains such as millet, quinoa, oat bran, and buckwheat could have come in contact with gluten.
- Legumes: Legumes can also be inflammatory for many people because they contain agglutinins. Like grains, legumes are difficult to digest, meaning there is more partially digested food in your gut.
- Certain Starchy Vegetables: Certain starchy vegetables including acorn squash, butternut squash, and spaghetti squash are considered good sources of carbohydrates.
- GMO Foods: Glyphosate, the herbicide used on GM crops, is a potent chemical that can attack the bacteria in your gut. The good bacteria that help with digestion and keep the bad bacteria in check are more susceptible to glyphosate.
- Fermented Foods: It is believed that anyone with Candida overgrowth should avoid fermented foods like yogurt until your yeast population is under control. The traditional Candida diet does allow for fermented foods. However, the prebiotics produced during the fermentation process feed bad bacteria and yeast.
- Dairy: Dairy does not directly feed Candida, yet it is a highly inflammatory food that it is recommended everyone eliminate from their diet, along with gluten. Inflammation damages your gut lining, which Candida overgrowth has likely already compromised.
Candida Die-Off
As your body eliminates Candida overgrowth, you may temporarily feel symptoms known as âdie-offâ effects. These can include headaches, fatigue, flu-like symptoms, and skin breakouts. While uncomfortable, these are signs that your body actively eliminates toxins.
Reintroducing Foods
Once you have successfully tackled Candida overgrowth, you might be eager to reintroduce some of your favorite foods. However, transitioning off the anti-Candida diet requires a strategic approach to avoid reigniting the problem. Reintroduce Foods Gradually: Start with small portions of one food at a time, waiting 3-4 days before introducing another.
A Strategic Approach: The Candida Support Protocol
Following an anti-Candida diet will help starve the Candida by removing the foods that feed it. From there, attack the Candida by taking supplements that help break down the cell wall and repopulate your gut with good bacteria. When combating Candida, remove all gluten, sugar, refined carbohydrates, alcohol, dried fruit, fruit juices, and fermented foods from your diet. Candida is always present in your mouth and intestines and actually aids with digestion and nutrient absorption.
Practical Considerations and Precautions
Before embarking on the Candida diet, it's essential to consult with a healthcare professional or registered dietitian. They can assess your individual needs, considering any underlying health conditions or medications you may be taking.

Potential Drawbacks
The Candida diet can be restrictive, potentially leading to nutrient deficiencies if not carefully planned. It's also crucial to avoid overly restrictive diets, especially for individuals with a history of disordered eating.
Individualized Approach
The Candida diet is not a one-size-fits-all approach. Some individuals may find it helpful, while others may not experience significant benefits. It's essential to listen to your body and make adjustments as needed.
The "Maybe" List
The "maybe" list contains those foods that are OK for many people, but which can still be a little risky for other Candida sufferers. Examples are beans, low sugar fruits, and starchy vegetables. At the beginning of your Candida diet, you might choose to include one or two of these foods. As your diet progresses and you start to reintroduce foods, this list is a useful place to start.
With all the âmaybeâ foods, the key is to start off with small portions and see what they do to your Candida symptoms. If you find that one food in particular is causing problems, it will be easy to recognize. Once you start adding some foods back you will find the Candida Diet much easier to follow, although you should never go back to the high sugar diet that you were probably indulging in before.
- Vegetables: These include the more starchy vegetables like carrots, beans, and potatoes. These should be minimized or eliminated from your diet at first, but can be included in small amounts as you progress through your treatment.
- Fruits: These fruits have low glycemic loads and are much less likely to spike your blood sugar than foods like bananas or grapes. Keep in mind that they should still be minimized or eliminated from your diet in the early stages of treatment.
- Grains And Pseudo-Grains: These grains and pseudo-grains are less likely to irritate the gut than glutenous grains like wheat or rye. Small amounts are OK but you would be better off sticking with options like millet or buckwheat, at least to start.
- Red Meats: Red meats arenât digested very well, and tend to raise the environmental pH in your intestines. Stick to white meats as much as possible.
- Nuts and Seeds: Nut milks and butters tend to be more problematic than the nuts themselves. Making your own is the best way, but if you canât do that then make sure that you buy a reputable organic brand.
- Fermented Foods: Foods like kefir and sauerkraut tend to be most beneficial for gut health. Kombucha and kvass tend to be much higher in sugars, and so less beneficial for Candida sufferers, but it depends on how they are made.
- Drinks: You should aim to greatly reduce your caffeine intake, especially if youâve been overdoing it. There are other options if thatâs proving impossible for you. Decaf coffee still contains small amounts of caffeine, but look for decaf that is made by the Swiss water process. Green tea is also lower in caffeine than coffee or black tea, and has other health benefits too.
