Prescribing the Candida Diet: Why, When, and How

Candida is a guest in most of our bodies – approximately 70% of people harbor Candida albicans in their guts. However, if given the chance, this yeast might overstay its welcome and start causing trouble.

The Candida diet, characterized by its emphasis on reducing dietary sugars and refined carbohydrates, has emerged as a popular approach to addressing yeast overgrowth and restoring gut health.

In this article, we will explore who should consider implementing the Candida diet, how to follow it effectively, and its potential benefits in managing Candida-related health issues.

Understanding Candida Overgrowth

Candida albicans is a yeast that most people have on their bodies, especially in warm, moist areas like our mouths, throats, and skin folds. Usually, our immune system keeps it under control, preventing it from growing too much. However, when our immune system is weakened or conditions in our body change – like taking antibiotics that kill good bacteria or eating a high-sugar diet – it can allow Candida to multiply more than usual.

Symptoms of Candida Overgrowth

When Candida overgrows, it can lead to infections with uncomfortable symptoms. Symptoms are dependent on the site of fungal overgrowth:

Vulvovaginal candidiasis (vaginal yeast infection) can cause itching, burning, and unusual discharge in the genital area.
Oral thrush affects the mouth and throat, causing white patches and soreness.
A fungal skin rash manifests as scaly, red, itchy patches.
A fungal infection of the finger or toenails (onychomycosis) causes discoloration and thickening of the affected nail(s).
Intestinal fungal overgrowth can cause abdominal pain, changes in bowel movements, and bloating.

The Candida Diet: An Overview

The Candida Diet website states, "The Candida diet is designed to improve gut health, reduce inflammation, and boost immunity." It can be one aspect of a comprehensive treatment plan to support good gut health and prevent/treat Candida overgrowth.

Dietary Principles:

The Candida diet is designed to reduce the growth of Candida albicans by making intentional nutritional choices that reduce added sugars and refined carbohydrates and incorporate anti-inflammatory foods that support a healthy microbiome. Sugar is the primary fuel source for yeast. By restricting dietary sugars, you deprive Candida of the substrate it needs to grow, replicate, and hide from the immune system (19, 20).

Key Components:

When you are first implementing changes to your diet, it can be challenging to know what exactly to eat.

To simplify matters, start by eating anti-inflammatory, low-sugar foods:

Non-starchy vegetables like leafy greens, broccoli, celery, asparagus, and zucchini
Low-glycemic fruits like citrus fruits and berries
Lean proteins such as poultry, fish, and tofu
Healthy fats from sources like avocados, olives, nuts, and seeds
Fermented foods: kefir, probiotic yogurt, sauerkraut
Anti-fungal foods like garlic, coconut oil, and ginger

You'll also want to avoid high-sugar foods that promote inflammation:

Sugar and sugar-containing foods. There are at least 61 names for sugar on food labels, and sugar is added to 74% of packaged foods (22). Check food labels and avoid/limit products that contain:some text
- Sucrose
- Fructose
- Maltose
- Dextrose
- Cane sugar
- Agave
- Honey
- Maple syrup
- Corn syrup
- Fruit juice
Refined carbohydrates like white bread, pasta, pastries, and breakfast cereals
Fruits like bananas, grapes, and dates
Alcohol

Intended Outcomes:

The Candida diet aims to support overall gut health, improve immune function, and promote balanced blood sugar levels to create an internal environment less conducive to yeast overgrowth. Ultimately, this will relieve Candida-associated symptoms.

Why Prescribe the Candida Diet?

While clinical trials evaluating the Candida diet are lacking, anecdotal reports suggest it is associated with symptom improvement. Studies and clinical observations suggest that dietary interventions aligned with its principles may effectively manage Candida-related health issues.

A 2017 in vitro study showed that higher glucose concentrations may promote Candida growth. Low carbohydrate diets effectively reduce blood sugar levels, which may create an environment less conducive to Candida proliferation. By limiting the intake of carbohydrates, particularly refined sugars and starches, individuals can minimize glucose availability in the bloodstream, depriving Candida of its primary energy source.

The Mediterranean and Candida diets share similarities in their emphasis on reducing inflammation, promoting gut health, and supporting a balanced microbiome. Extrapolating from the findings that Candida overgrowth may contribute to irritable bowel syndrome (IBS) symptoms and that the Mediterranean diet has shown efficacy in treating IBS due to its anti-inflammatory and gut-friendly properties, it is reasonable to conclude that the Candida diet could be effective in managing Candida-related IBS.

Which Patients Would Benefit from the Candida Diet?

Identifying which patients stand to benefit most from its principles and dietary modifications is the first step in determining the applicability of the Candida diet as a therapeutic intervention.

Assessment and Diagnosis:

The Fungus Related Disease Questionnaire (FRDQ-7) is a validated questionnaire designed to assess symptoms related to fungal infections. It consists of seven questions about antibiotic use and the frequency and severity of symptoms relieved by taking the antifungal agent called nystatin (24). Patients with a score of 4 or higher likely have fungal-related disease.

The following tests can help make the diagnosis of Candida overgrowth:

Comprehensive Stool Test: A stool analysis begins with the patient collecting stool samples at home over 1-3 days. The stool is analyzed for yeast levels to determine if Candida albicans or other yeast levels are abnormal in the gut.
Candida Antibodies: The immune system produces immune proteins called antibodies (IgA, IgG, and IgM) in response to a Candida overgrowth. These antibodies can be measured through a blood test and help clarify the overgrowth's location and chronicity. (18)
Organic Acid Test: Organic acids are metabolic byproducts that can be measured in urine. Certain organic acids, such as arabinose, are produced by fungi; elevations suggest yeast overgrowth.

Patient Selection Criteria:

Healthcare providers should assess patients' medical history, symptom severity, and readiness for dietary change and provide education, support, and monitoring throughout the dietary intervention process to ensure safety and effectiveness. By considering these criteria, healthcare providers can identify suitable candidates for the Candida diet and tailor nutritional recommendations to meet individual needs and goals,

Implementing the Candida Diet: Practical Guidance

Once you've discovered you have Candida overgrowth and want to start the Candida diet, follow these steps.

Starting the Diet:

Start by becoming familiar with the principles and guidelines of the diet. Establishing care with a nutritionist or dietician can help ease the transition as you learn what foods to eat and avoid and manage challenges as they arise.

Identify the factors that might have led to fungal overgrowth and eliminate them. Then, transition to the Candida diet, making small changes over time rather than drastic ones overnight. Start by eliminating the most problematic foods: those with added sugars, such as candy, baked goods, and soda.

Make healthy food swaps. Examples might include:

Cauliflower rice instead of white rice
Strawberries instead of bananas
Homemade oatmeal instead of sugary cereal

Sample Meal Plans and Recipes:

The Candida Diet website has an extensive archive of free recipes. Meals should emphasize healthy fats, lean proteins, fiber, herbs, and spices so that you feel satisfied after eating and are less likely to give in to sugar cravings.

A sample meal plan may include:

Breakfast: scrambled eggs with a vegetable hash and avocado
Lunch: spinach salad with salmon, dressed with olive oil and lemon
Snack: hummus and veggie sticks
Dinner: tandoori chicken with curried cauliflower rice
Dessert: plain yogurt topped with blueberries and cinnamon

Monitoring and Adjustments:

Patients and doctors can monitor patient progress on the diet through clinical symptoms and repeat labs. Proponents of the diet say that people following the diet can begin to experience relief from Candida symptoms in a matter of weeks. Repeat tests can also provide objective data on fungal growth as patients follow the treatment plan.

Adjustments may be needed if patients experience side effects. Fungal die-off (Herxheimer reaction) can occur when antifungal therapies are initiated. When this happens, fungal metabolic byproducts are released rapidly in the body, triggering an immune response and inflammation. This can temporarily exacerbate and cause flu-like symptoms. The severity of symptoms can vary from person to person. It does not need to be treated, but some things can alleviate symptoms to make patients more comfortable:

Stay well hydrated: Drink between 0.5-1 ounce of water per pound body weight daily.
Use activated charcoal as a binder: Take 250-1,000 mg three to four times daily, at least 30 minutes before or one hour after food, medicines, or other supplements.
To reduce inflammation, supplement with antioxidants, such as 250-1,000 mg of vitamin C one to three times daily.
Support the liver with:some text
- N-acetyl cysteine (NAC): 600 mg one to three times daily
- Milk thistle: 140-200 mg three times daily

Challenges and Considerations

Here are common challenges patients may face on the Candida diet, along with tips to address them:

Dietary Restrictions and Nutritional Adequacy

Focus on incorporating a wide variety of nutrient-dense, whole foods such as vegetables, lean proteins, healthy fats, and low-sugar fruits to ensure you meet your nutritional needs despite being on a restricted diet.

Work with a nutritional counselor to assist with meal planning and recipe modification. This will help you create balanced and satisfying meals that adhere to the Candida diet principles.

Sugar Cravings

Naturally sweet foods, like berries, can satisfy sugar cravings in a healthier way.

Identify and address potential causes of sugar cravings, including:

Boredom and other emotions
Undereating and insufficient fiber intake
Hormonal imbalances
Lack of sleep

Social Implications

Socializing often revolves around food. Dietary restrictions may require individuals to navigate social situations differently and can impact their ability to participate in communal dining experiences. Managing dietary restrictions often involves open communication with friends and family to advocate for their needs and finding alternative social activities, such as outdoor activities or game nights.
