Candida (Candida albicans) is a fungus that is part of the body’s normal microbial flora. Under normal conditions, Candida albicans doesn’t cause problems; in fact, it plays an important role in digesting sugars through a fermentation process.
When, however, immune defences are lowered and the body’s balance is disrupted, Candida can proliferate excessively, giving rise to troublesome infections. Oral candidiasis is particularly common in children and infants, where it is commonly known as oral thrush. However, adults can also be affected — particularly following a prolonged course of antibiotics or after a period of extended stress. When this happens, action must be taken promptly… but how?
Oral candidiasis can be treated with various products, some requiring a medical prescription and others available over the counter. If you suspect you have an oral candida infection, consult a specialist or your doctor — but remember also that this fungus can be combated through diet as well.
Diet plays an important role in the growth of Candida albicans. Certain foods promote its proliferation, while others inhibit it. Knowing which foods to include in one’s diet can be a valuable aid in facilitating recovery and preventing the onset of new infections. Since dietary restrictions can be quite stringent — with the risk of nutritional deficiencies — it is always advisable not to improvise, to follow this regimen only for short periods, and to consult a nutritionist who can provide personalised guidance.
It’s also important to remember that Candida thrives in acidic environments. A healthy mouth with a neutral pH is naturally less prone to infection – and once again, diet can help maintain this balance.
Oral Candida: Foods to Avoid
Candida albicans is a fungus with a “sweet tooth” that feeds primarily on sugars. Sweets, honey, carbonated drinks, candies, and dried fruit (dates, raisins, dried figs) are all foods particularly rich in simple sugars — Candida’s favourites. Eliminating these foods from our diet effectively puts Candida on a “diet” too, limiting its growth. Conversely, excessive consumption of simple sugars creates a feast from which this unwelcome fungus can draw to thrive. Unfortunately, cutting out unhealthy desserts alone is not enough to reduce sugar intake in our meals. Fruit should also be consumed in moderation, avoiding particularly sugary varieties (especially figs and grapes) and instead favouring less sweet options, such as green apples or berries.
It is also best to limit or eliminate milk, butter, and cheese, especially less-aged dairy, as they contain lactose, another type of sugar.
Gluten-containing cereals and, in general, all leavened products with yeast (for example, baker’s yeast) should be restricted or avoided. Potatoes, which are rich in carbohydrates and starch, are also not allies against Candida.
Alcoholic beverages should be completely avoided: they not only contain fermenting yeasts but are also high in sugar. Cutting alcohol benefits your overall health – not just your fight against Candida!
Finally, to maintain proper oral balance, it’s best to limit highly acidic foods that can alter mouth pH and create an environment favorable to Candida growth.
Oral Candida: Foods You Can Eat
So, what foods can help us combat oral Candida at the table?
Fortunately, many foods are not only allowed but also recommended for their anti-inflammatory properties.
In an ideal diet against oral Candida, vegetables are a go-to, with a preference for less sweet varieties. Leafy greens such as lettuce, broccoli, and kale are especially recommended, as they are rich in fiber and folic acid. Sweeter vegetables, like pumpkin and carrots, should be consumed in moderation.
Gluten-free grains are also recommended, preferably whole grains. Animal proteins – such as eggs, fish, and meat – are encouraged as well, with a preference for white meats.
We can add certain particularly beneficial foods to our diet to help counteract the growth of Candida. Raw garlic, for example, has a well-documented anti-inflammatory function. Certain oils are also valuable allies: coconut oil and extra virgin olive oil are rich in fatty acids with a marked antifungal and antibacterial action. In this case too, consumption in raw form is always recommended.
Turmeric, the yellow spice that gives color to certain types of curry, contains a compound called curcumin. According to some studies, this substance is highly beneficial in fighting Candida, as it can inhibit its growth and even kill the yeast.
Remember to enrich your diet with yogurt and other probiotic-containing products: strengthening the intestinal bacterial flora helps make our body more resilient and therefore better equipped to overcome candida.
Practical Tips
Relax more! Going through a particularly demanding period, both physically and mentally, with a hectic schedule and high stress levels, can negatively affect not only your mood but also your immune system, potentially triggering stress-related oral candidiasis.
Avoid excessively large meals, which can slow digestion and reduce the wellbeing of the bacterial flora. Pay particular attention to oral hygiene after meals: oral candida thrives among food residues, and eliminating as much as possible deprives the microorganism of the substrate on which it grows. Moreover, after meals, oral pH naturally tends to become more acidic, creating an environment that favours the growth of this unwelcome microorganism. Brushing teeth and using mouthwashes or dental sprays that can help neutralise oral pH creates an unfavourable environment for Candida growth. Cariex® in particular acts immediately, reducing acidity and restoring the healthy neutrality of the oral cavity.
Candida albicans infections can be recurrent and are often difficult to treat. Diet can play an important role in preventing this condition and can also support treatment if an infection is already present.
Always consult your doctor to plan a medical treatment strategy, and pair it with the healthy eating guidelines we’ve outlined in this article.
