What is the candida diet?

Candida diet food. Assortment of food that fights candida

Thrush or candidiasis is the term given when the candida present in your system starts to become more prevalent in relation to the other organisms (your microflora) residing there. This can sometimes happen after long-term use of antibiotics, steroids and some birth control pills; or during pregnancy, if you are overweight, have an existing bacterial infection, or have a pre-existing health condition such as a compromised immune system, diabetes or psoriasis. Those with severely compromised immune systems are considered to be most at risk.

How does the candida diet work?

The candida diet is restrictive and as a result challenging: it eliminates all the foods thought to contribute to the growth of candida and is intended to be followed only for the period of time in which you are experiencing symptoms.

What foods to eat on the candida diet?

The diet promotes whole foods that are low in sugar as well as non-starchy vegetables, lean protein such as meat, beneficial fats from sources rich in omega-3 fatty acids and non-caffeinated drinks.

Examples include:

Low-sugar fruit including lemons, limes and berries
Non-starchy vegetables such as spinach and kale
Gluten-free grains including millet, quinoa and buckwheat
Lean protein including chicken, salmon, turkey, eggs and sardines
Fats such as avocado, olives, unrefined coconut oil, flax oil, extra-virgin olive oil and sesame oil
Certain dairy such as ghee, kefir and live yogurt
Nuts and seeds (free from moulds)
Herbs and spices
Herbal teas

What foods to avoid

The diet is restrictive and discourages the intake of high-sugar foods, additives, processed foods, certain meats, fats and oils as well as caffeinated and alcoholic drinks.

Examples of the food and drinks to exclude are:

High-sugar fruit such as bananas, dates, grapes and mango
Refined carbs such as white flour
Gluten grains including rye, wheat and barley
Processed meats
Refined oils and fats
Certain dairy such as cheese, milk and cream
Sugar and artificial sweeteners
Nuts and seeds that are high in mould, such as peanuts
Caffeine, alcohol and sugary drinks
Additives

Do candida diets work?

The candida diet is not a weight loss diet, but an eating plan that aims to address a specific issue (an overgrowth of candida). However, there is limited evidence to support the effectiveness of the 'candida diet' for this purpose, although anecdotal reports suggest people may feel better. Whether these improvements have more to do with cutting out refined and processed foods, alcohol, caffeine and sugars, rather than any specific impact on the levels of candida, is strongly debated.

One 2018 study that involved a candida diet combined with an anti-fungal medication reported those people who adopted the diet had significantly reduced numbers of candida yeasts in their stool, compared to those who didn’t.

Is a candida diet healthy? A nutritionist's view…

Candida is a yeast-like fungus that forms part of the normal microflora of the human mouth, gut and vagina – it’s something we all have and, for most of us, doesn’t cause a problem. There are numerous candida species with candida albicans being the most common. In a healthy person it causes no problems – however, because it is an opportunistic pathogen, if your immune defences are low or you have a pre-existing health condition, it may become problematic.

The candida diet is strict and needs careful planning. For those on a budget, or those who enjoy eating out or already follow a restrictive diet, it may pose difficulties. Eliminating such a wide variety of foods may leave you at risk of an unbalanced and nutritionally inadequate diet.

That said, the diet does focus on healthy whole foods that are low in sugar, are of a high quality with have minimal additives. The diet is also intended to be followed for a limited time and only while you are experiencing symptoms. Although there are some health benefits to the foods that are encouraged by the diet, apart from anecdotal reports, there remains no clear evidence that the candida diet has clinical benefits.

Who shouldn’t follow the candida diet?

Vulnerable groups should exercise caution before adopting such a restrictive diet, these include:

those who are pregnant or breastfeeding
diabetics
the elderly
the young (under 18 years of age)
those who are on prescribed medication
those who have a low body mass index (BMI less than 18.5)
those with emotional or psychological issues around food, including any history of eating disorders

If you have symptoms that are causing you concern, or you suspect you have a fungal infection, refer to your GP or health care practitioner.

If you are considering any form of diet, please consult your GP or a registered dietician first to ensure you can do so without risk to health.
