Skin Health Fungal, Bacterial & Viral Infections What to Eat When You Have Candidiasis By Cathy Wong Updated on March 25, 2024 Medically reviewed by William Truswell, MD Print Table of Contents View All Table of Contents What Is Candida? How Does the Candida Diet Work? Nutrition What Research Says Foods to Eat on the Candida Diet Foods to Avoid on the Candida Diet Summary Candida albicans is the fungus most commonly responsible for yeast infections (vaginal candidiasis) and oral thrush (oral candidiasis). Alternative medicine practitioners often claim that a special diet can treat or prevent these conditions. The Candida diet emphasizes restricted intake of sugar and carbohydrates - two dietary components believed to "feed" an acute Candida infection. People use this diet to prevent Candida infections. This article explains how to manage candidiasis by changing your diet. It covers the benefits of the Candida diet, what to eat, foods to avoid, and how long to follow it to treat or prevent candidiasis. Symptoms of Yeast Infections Lauren Burke / Digital Vision / Getty Images What Is Candida? Candida albicans is a normal part of a person's microbiota and occurs on the skin, in the mouth and throat, in the gut, and in the vaginal tract. Usually, it exists in a balance, not causing problems. However, if there is an overgrowth of Candida, infections can occur. This can happen because of a change in someone's immunity, microbiome, and even a person's stress level. How Does the Candida Diet Work? The theory underpinning the Candida diet suggests that the complete avoidance of sugar and other foods will deprive yeast of the fuel needed to grow. This concept is understandable, given the way yeast is used in baking or beer manufacturing. Sugar "feeds" yeast cells, allowing them to multiply much faster. Alternative practitioners contend that the same principles can be applied in medicine, wherein the excess sugar intake fosters Candida growth, and the restriction of sugar suppresses it. Proponents of the Candida diet claim that it takes around a month to notice any changes, if not longer. Some people may experience no changes at all. Sugar The most widely discussed aspect of the Candida diet is the strict avoidance of sugar. This may be particularly relevant for women with diabetes, who are more likely to get yeast infections than non-diabetic women. It is important to remember that the body requires sugar and carbohydrates for overall functioning. For some, cutting back too drastically on these food sources could prompt symptoms associated with hypoglycemia, such as fatigue, headache, jitteriness, weakness, loss of concentration, and anxiety. Diabetes is a disease characterized by an abnormal increase in blood sugar (glucose). While yeast is not typically found in the bloodstream (with the exception of invasive candidiasis in people with advanced HIV), any rise in blood sugar can alter the glucose concentration in the mouth and vagina, helping yeast grow. That said, candidiasis in people with diabetes is driven not so much by sugar consumption as by the inability to correct the dysfunction that gives rise to high blood sugar (hyperglycemia). This includes insufficient insulin production and/or resistance to insulin's effects. While the avoidance of sugar may reduce the risk of hyperglycemia in people with diabetes (and, in turn, the risk of candidiasis), the consumption of sugar won't inherently increase glucose levels in the mouth or vagina if the blood glucose levels are under control. At present, there is little solid evidence that the restriction of sugar will either prevent or relieve Candida infections in people without diabetes. One study concluded that probiotics may improve short-term cure and relapse rates in women with yeast infections but conceded that the quality of current research is "low to very low." Gluten Some Candida diet plans advocate the restriction of wheat, a recommendation construed by some to mean that a gluten-free diet may help prevent yeast infections. There is no evidence that wheat and gluten-containing foods contribute to yeast overgrowth or increase the risk of candidiasis. Unless you have celiac disease, a gluten-free diet is not necessary. With that said, there is evidence, albeit weak, that Candida albicans can trigger celiac disease symptoms, as it has cell wall compounds similar to those in gluten that trigger the immune cell reaction involved in the disease. Yeast People often wonder if they must avoid yeast-containing food to prevent yeast infections. The simple truth is that the microorganisms used in food are not the same as those that cause candidiasis. Yeast-containing foods like bread and beer are typically made with Saccharomyces cerevisiae, an entirely different form of yeast. With few exceptions, it is extremely rare for S. cerevisiae to cause yeast infections. In fact, the opposite may be true. Nutrition Candida diets (some referred to as candida "cleanses") can be very restrictive. Given the nature of these restrictions, it would be difficult to adhere to the diet for a long period of time and maintain adequate nutrition. It is important to remember that the body requires sugar and carbohydrates for overall functioning. For some, cutting back too drastically on these food sources could prompt symptoms associated with hypoglycemia, such as fatigue, headache, jitteriness, weakness, loss of concentration, and anxiety. What Research Says There is currently little evidence to support the use of the Candida diet to prevent vaginal yeast infections and oral thrush. Furthermore, the theory behind sugar and carbs fueling yeast growth does not address the underlying cause of candidiasis—namely, a depleted immune system and/or external forces that alter the balance of the natural flora of the mouth and vagina. Despite claims that the Candida diet can "boost" the immune response, there has yet to be any evidence that diet alone can amplify the immune response to neutralize a Candida infection. Some studies examine the role of diet on gut flora, including Candida. One study shows that diets rich in vegetable fiber, Vitamins D and E, Omega-3 fatty acids, micronutrients, and probiotics can help regulate the amount of Candida in the gut. However, this is mostly beneficial for preventing systemic candidiasis, a Candida infection that spreads to organs like the heart and brain and can be life-threatening. Foods to Eat on the Candida Diet Foods included in the Candida diet are free of sugar and gluten, lean proteins, artificial sweeteners, non-starchy vegetables, probiotics, and certain healthy fats. Lean Proteins Lean protein, such as eggs and skinless poultry, are usually allowed on the Candida diet, as are bone broth and certain fatty fish. Low-mold nuts and seeds are also approved. Examples include: Eggs Lean cuts of chicken or turkey Salmon, herring, sardines, and anchovies Bone broth Nuts and seeds (almonds, flax, pumpkin, sunflower) Non-Starchy Vegetables Non-starchy vegetables are a great way to ensure you're getting micronutrients in the Candida diet. Low-sugar fruits like limes and lemons are OK, as are small portions of berries. Some examples of non-starchy vegetables include: ArtichokesBroccoliKaleTomatoes Gluten-Free Grains Gluten is avoided in the Candida diet, so any grains you consume should be gluten-free. These include: TeffQuinoaOat bran Artificial Sweeteners Since sugar is avoided in the Candida diet, artificial sweeteners can be used instead. They include: SteviaMonk fruitXylitolErythritol Healthy Fats Eating healthy fats is an important way of making sure you consume the necessary amino acids. AvocadoOlivesCoconut, flax, olive, and sesame oil Probiotics The use of probiotics in treating yeast infections is controversial. Although probiotics work by increasing bacteria beneficial to the vagina and gastrointestinal tract, their ability to prevent or treat candidiasis is subject to debate. While many studies suggest that a daily probiotic can slightly improve imbalances that lead to yeast infections, others do not. Foods rich in probiotics are: GheeKefirProbiotic yogurt Kombucha Foods to Avoid on the Candida Diet There are many foods restricted on the Candida diet. Sugary, starchy, and rich foods are all prohibited on the Candida diet. Carbohydrates, most dairy, fruits, and non-lean meats are also foods to avoid. Sugar-Sweetened Foods Food sweetened with sugar in any of its forms is not advised on the Candida diet. Forms of sugar to look for on food lables include: AgaveAspartameCane sugarCorn syrupHoneyMolasses Starchy Vegetables For vegetables, stick to non-starchy options like broccoli, kale, and tomatoes. It may be recommended that you avoid produce that is likely to be exposed to mold, such as mushrooms. Starchy vegetables include: White potatoesSweet potatoesYamsCornBeansCarrotsBeetsTurnipsWinter squashes Carbohydrates Proponents of the Candida diet will often contend that carbohydrates contribute as much to candidiasis as sugar. The contention is based on the popular (and oversimplified) belief that "carbs are converted into sugar." While it is true that carbohydrates are broken down into smaller sugar molecules called monosaccharides, the body's response to these molecules can vary. Different foods have different glycemic index (GI) values, meaning some foods cause blood sugar to rise significantly while others don't. Moreover, the sugar molecules don't simply migrate to the mouth or vagina or the more you eat. Some will be burned for immediate energy, some will be stored for future energy, and others will be excreted from the body to keep the blood sugar levels from rising too high. In short, you won't experience abnormally high sugar in your blood or mucosal tissues if you have normal insulin levels and normal insulin tolerance. Still, those who follow the Candida diet avoid carbohydrates. At present, there is little to no evidence that restricting carbohydrates or using low-carb diets impacts the incidence or severity of Candida infection. Fruits Fresh, frozen, canned, and dried fruits high in sugar are generally excluded from the Candida diet. Juices made from these fruits, or those that are sweetened, should also be avoided. This includes: PrunesBananasGrapesRaisinsApplesPears Non-Lean Meat The Candida diet excludes red, organ, and processed meats. Shellfish and large fish (like tuna and swordfish) might also be excluded as they are more likely to have been exposed to heavy metals like mercury. Meats to avoid are: Red meat and organ meatTuna and swordfishShellfishLunchmeatHot dogsSausageBacon Dairy Full-fat dairy is often limited on the Candida diet with the exception of probiotic yogurt, ghee, and real butter (in moderation). Dairy foods that are not allowed include: Ice creamAll sugary milk, such as frozen yogurtMoldy blue cheesesProcessed cheeseCream cheeseCheese dipping snacks Natural Remedies for Candida Processed Foods Processed foods often have sugar where you might not imagine. About 15% of the sugar in the typical diet comes from added sugars. Avoid: Frozen meals and snacksPackaged snack foods Dried fruit (dates, apricots, prunes, raisins) Bottled salad dressings, dips, and condiments How Oral Thrush Is Treated If you are prone to recurrent yeast infections or oral thrush, it is important to see a doctor to determine the underlying cause. Recurrent candidiasis can never be considered "normal" under any circumstance. Summary The Candida diet is a very strict no-sugar and no-carbohydrate diet aimed at preventing infection from an overgrowth of Candida. Although many hope that a diet change can prevent these infections, it is incredibly tough to maintain due to how restrictive it is. Furthermore, there is not much science backing the notion that avoiding these foods will prevent vaginal yeast infection or oral thrush. If you are experiencing troublesome infections, see a healthcare provider to discuss what lifestyle changes might best benefit you.
