The Candida Diet: What It Is, What to Eat, and Does It Actually Work?

What Is the Candida Diet?

The candida diet was created to help limit the growth of Candida albicans, a yeast that naturally lives in your mouth, gut, skin, and vagina. It only becomes an issue when it grows out of balance, leading to oral thrush or a vaginal yeast infection.

Since candida feeds on sugar, the diet claims that reducing added sugars and refined carbs can reduce or treat overgrowth. While it sounds like it makes sense, there isn't much research to support the diet for candida treatment. In the end, candidiasis is a medical condition that requires professional treatment (usually, antifungal medications).

That said, many people say they feel better on this diet, but that could just be because it's rich in whole, healthy foods.

Foods to Eat on a Candida Diet

If you don't take a very strict approach, the candida diet is like most others, focused on vegetables and fruit, proteins, and healthy fats.

Non-Starchy Vegetables and Low-Sugar Fruits

Since candida feeds on sugar, the candida diet recommends low-sugar fruits in particular, and non-starchy vegetables. The strict version of the diet reduces starchy vegetables and sweeter fruits like bananas, grapes, and mangoes. But from a scientific standpoint, there's no evidence that you should reduce any type of fruit or vegetable to treat or prevent candida overgrowth. Fruits and vegetables act as a prebiotic, with their fiber feeding the "good" bacteria in your gut.

Protein and Healthy Fats

We don't metabolize white flour or sugar the same as we do proteins and fats. Protein keeps you full and helps repair and maintain healthy tissues with its essential amino acids. Meanwhile, healthy fats (like omega-3's) can reduce inflammation. Both also don't spike your blood sugar, meaning fewer cravings, too.

Fermented Foods and Probiotics

We keep hearing about how fermented foods are good for your gut, and the research agrees. They have the "good" type of bacteria that can support a healthy balance of microbes, which might naturally help prevent candida overgrowth (along with a healthy lifestyle).

Foods to Avoid on a Candida Diet

This diet is known for being restrictive, so if you start feeling stressed, it might be a sign that it's too much to manage. The goal is to create overall balance in the end, so taking it slow to not overwhelm yourself is also important.

Sugar and Sweeteners

The main focus is on reducing added sugar. That includes table sugar, honey, maple syrup, agave, and artificial sweeteners, plus the added sugars found in processed foods (sauces, dressings, breads, etc.).

While some reduce fruits because they have sugar, they also have fiber, vitamins, and minerals that support good bacteria.

In the end, if you're needing something sweet, a tasty mango or small dessert that satisfies you might be better than stressing out and feeling restricted over eating nothing (and potentially later binge eating).

Refined Grains and Starchy Foods

In general, white bread, pasta, white rice, potatoes, corn, and pastries aren't recommended. These foods tend to have less fiber and are broken down into sugar quickly. Other whole grains, like quinoa or oats, don't spike blood sugar as quickly, especially when paired with vegetables and protein.

Alcohol, Caffeine, and Certain Dairy Products

Alcohol can easily disrupt your gut bacteria. It kills off "good" bacteria, leaving space for candida, it feeds yeast since it's high in sugar, and it can weaken your gut wall.

Some people also reduce caffeine since it can upset the stomach, but there isn't any evidence to support that it helps prevent or treat candida overgrowth. Several studies have found that caffeine can have antifungal properties.

Dairy doesn't have to be avoided either, but some do because it has lactose (milk sugar). Like caffeine, there isn't evidence to show that cutting out dairy helps. In fact, dairy products with probiotics like yogurt add good bacteria that can help prevent candida overgrowth.

Potential Benefits of the Candida Diet & What the Research Shows

Like any restrictive diet, you'll want to do your research before giving it a try. Here's what to consider.

Why Some People Feel Better on This Diet

If you're used to eating a diet higher in processed foods or sugar, eating more whole foods should naturally help you feel more energized. Any diet that's primarily vegetables, proteins, fruits, and healthy fats can add more nutrients and decrease blood sugar spikes.

We also tend to naturally eat less when we eat filling, balanced meals. This can lead to weight loss, better digestion, and an easier time focusing, to name a few.

What Science Says About Candida Overgrowth

There isn't enough credible research to suggest that candida overgrowth is caused simply by a high sugar diet. However, your overall diet and lifestyle will affect your gut and immune system.

Candida also isn't meant to be self-diagnosed or treated by a diet. It requires a medical professional's treatment.

Potential Challenges and Considerations of the Candida Diet

Any type of "diet" can have its drawbacks. It can be very restrictive: if you cut too much, it can backfire and leave you stressed, overwhelmed, and potentially deficient in nutrients. And not everyone needs this diet: a balanced, healthy diet works for most people, and just because you have symptoms like brain fog or bloating doesn't mean you have candida and need to eat restrictively.

This diet, like any restrictive diet, can be particularly triggering for people with disordered eating. If you notice yourself becoming obsessed with food, try working with a registered dietitian specialized in eating disorders. They understand how tied we get to what we eat and the unhealthy habits we can develop in our quest to be "healthy."

Working With a Registered Dietitian for a Personalized Diet

We underestimate the importance of consistent support and accountability. Working regularly with a registered dietitian can completely change how you feel about food. They're there to offer you options you hadn't thought of before and reduce the overwhelm that comes with changing habits.

They're trained in offering advice for each person's unique lifestyle and needs. They also get how stressful it is to suffer from health conditions. They can become part of your support system that lifts you up, motivates you, and holds you to your goals (they also make sure your goals are practical so you don't overshoot and feel like a failure).

A registered dietitian can help you build a balanced plan without unnecessary restriction. See if your insurance covers a dietitian before making major dietary changes.

Starting the Candida Diet: Practical First Steps

You don't need to overhaul your life. Go slow to give yourself time to adapt and build healthy habits that last. Otherwise, we fall into the New Year's resolution trap of trying to change too much too soon, only to end up criticizing ourselves and feel even worse.

1. Add Vegetables and Protein: Start with changing one thing on your plate that will help fill you up. For example, add one serving of vegetables or protein to each meal. Keep your freezer stocked with frozen veggies that you can reheat and add to your plate fast. The same goes for protein, you can precook and freeze chicken or have something like shrimp that defrosts quickly to add to a stir-fry or pasta. The trick to making this last is to make sure you're adding foods you like. For example, try a new healthy recipe at least every other week to get some variety and excitement for your taste buds.
2. Look for Added Sugars: We don't realize how much sugar (and salt) is added to our foods. It's mostly in processed foods, but sometimes even in things we think are healthy. Start reading ingredients and look for low sugar and salt options. Added sugar hides in places you might not expect, like bread, fruit juice, plant milk, flavored yogurt, breakfast cereal, granola bars, canned foods, and condiments like BBQ sauce or salad dressings.
3. Keep a Food and Symptom Journal: You might want to track what you eat when you first start eating healthier. It can help you see where you're unknowingly getting more processed foods or sugar than you realized. Just watch out if you start becoming too obsessive about tracking. If you're getting upset every time you go "over" your calories and start "making up for it" with excessive exercise or cutting calories later, you might be moving towards disordered eating.
4. Get Professional Support Before Major Changes: Healthcare professionals recommend seeing a doctor before making any big dietary changes. You'll want to get blood work done and find out if there are any underlying conditions or deficiencies before beginning. Otherwise, you could unknowingly worsen a condition or symptoms.

Frequently Asked Questions

How long should you stay on a candida diet to see results?

It's different for everyone and depends on your current health status. In general, a consistent, balanced diet for several months helps support a stable gut.

Can you follow a candida diet if you're vegan or vegetarian?

Yes, but it can be more challenging since the diet already limits many foods. Working with a registered dietitian can help you meet your protein and nutrient needs while avoiding unnecessary restrictions.

Is there scientific evidence that the candida diet actually works?

It can help you feel better overall since you're reducing processed foods and adding more nutrition (protein, fiber, vegetables, etc.). However, it can't cure or treat fungal overgrowth on its own.

What are common mistakes people make on the candida diet?

A mistake to avoid is becoming so restrictive that it becomes stressful (or leads to disordered eating). Also, cutting out entire food groups without being sure you need to can increase the risk of becoming deficient in some nutrients.

Is the candida diet safe to follow long-term?

It depends; the very strict versions aren't usually recommended long-term because they're hard to maintain and can cause stress, and can limit important nutrients. An overall balanced approach of eating mostly whole foods is ideal for the long term.
