What Can My Daughter Eat With A Yeast Allergy?
Would I be right in suspecting she has been diagnosed with candidiasis - an overgrowth of Candida yeast in the gut?
If this is the case, or even if the only information you have is that she has a yeast intolerance, the basic concept is the same - to 'starve' yeast out of the system by not feeding it.
In theory, this should be simple as it only involves cutting out sugary, yeasty or fermented foods.
But in practice it means not eating any of the following common foods:
• Chocolate, confectionery or sugary foods of any kind
• Bread
• White flour
• Alcohol
• Vinegar
• Blue cheeses
• Mushrooms
• Peanuts and pistachios (in case they are contaminated with traces of mould)
• Pickles
• Soy sauce
• Vinegar
• Marmite
• Fruit juice and sugared soft drinks
Though this may seem restrictive, foods your daughter can eat are plain meat and fish, unsugared cereals, skimmed milk and plain yoghurt, green vegetables, beans and grains such as barley, brown rice, corn, millet, rye
and oats.
Potatoes, squash and sweet potatoes can be eaten in moderation, and though whole fruit is okay, fruit juice should be avoided as it such a concentrated sugar source.
Bearing with the diet is worth it as symptoms like tiredness and bloating should soon start to lift. After three months your daughter may be able to start slowly reintroducing foods - though she will probably always have to be careful with yeasty sugary foods.
To help her to feel better quicker she should also take a probiotic (friendly bacteria) supplement.
Other supplements that may help, include garlic, pau'darco (a Brazilian herb claimed to boost immunity) and caprylic acid (extracted from coconuts and said to be antifungal).
For further advice she could book an appointment with a nutritional therapist. Contact The British Association of Nutritional Therapists on 0870 606 1284.

A yeast infection can feel like itching or even burning. Or you may have swelling so extreme, it leads to sores. Sexual intercourse may be painful. Whether your symptoms are mild or severe, a yeast infection can be uncomfortable.
Yeast infections are caused by a fungus. It generally causes your vagina and vulva (the tissues at the opening of the vagina) or your penis to itch. You may also have a discharge.
Knowing how to spot the symptoms of a yeast infection can help you get the most effective treatment.

Your vulva and vaginal opening or your penis may look red, swollen, and irritated. There may be a white coating or shiny sores on your vaginal or penile tissue. Your discharge may be different than normal. Your symptoms will vary depending on how severe your infection is.
Yeast infection discharge
It may be watery or thicker and look like cottage cheese. It's usually whitish to yellowish in color. A vaginal yeast infection shouldn't smell different than normal. Symptoms can vary from person to person.
Your symptoms depend on where the infection is and how your body responds. Your symptoms may be mild, moderate, or severe. Or you may have no noticeable symptoms.
Vaginal yeast infection symptoms
Yeast infections are a common type of vaginitis or vaginal infection. Three of every four women and people with a vagina get one in their lifetime. And many have more than one.
Also known as vaginal candidiasis, if you have a vaginal yeast infection, you'll most likely have extreme itching in and around your vagina; this is the most common symptom. In addition to itching, you might also have:
Penile yeast infection symptoms
A penile yeast infection is also called candida balanitis. This can happen when there's an overgrowth of fungus on the penis or if you have sex with a partner who has a vaginal yeast infection.
About 3%-11% of men and people assigned male at birth will get a yeast infection in their lifetime. It tends to happen on moist, warm, creased areas of skin such as the head of the penis and foreskin.
It's more common if you aren't circumcised and for children under age 4. About 1 in 30 uncircumcised people will develop a yeast infection. It's also more common if you have phimosis, which means the foreskin doesn't easily pull back over the penis.
The symptoms include:
Sometimes the symptoms of a yeast infection can be more serious and require extra care. Or you may get repeated infections. You might need a longer course of treatment or a prevention plan with your doctor to keep the infection from coming back. Severe yeast infections are also called complicated yeast infections.
You can get a more complicated infection if:
Your infection might also be more complicated if it's caused by a different type of fungus than what commonly causes yeast infections. This can mean the usual over-the-counter treatments are not as effective.
Signs of a complicated infection include:
Vaginal yeast infection and bacterial vaginosis (BV) are different types of vaginitis. BV is caused by bacteria rather than a fungus. Both infections can cause itching and a burning feeling when you pee. However, other symptoms are not the same.
You may have BV rather than a yeast infection if your vagina has a bad smell or if you have a thin, white, green, or gray discharge.
See your doctor if you think you may have BV or if you're not sure what infection you have.
Both infections may cause discomfort and a burning sensation when you pee. But while a yeast infection causes symptoms like vaginal itching and a thick or watery odorless discharge, a urinary tract infection (UTI) does not. If you have a UTI, you may have these symptoms instead:
Call your doctor if your symptoms don't improve within 72 hours of starting treatment. Call right away if you have any signs of a complicated infection.
You should also make an appointment with your doctor if:
If you think you have a yeast infection but aren't sure, it's important to see your doctor for a proper diagnosis. Your doctor can also let you know if something else may be causing your problems.
Treatment can help relieve your symptoms, keep an infection from becoming severe, and prevent you from spreading any potential infections during sex.
If you have itching around your vagina or penis and a thick, white, chunky, or watery discharge, there's a chance you have a yeast infection. Call your doctor if you're not sure. Over-the-counter treatments often provide relief in a few days.
Surprising Evolutionary Pattern In Yeast Study
University of North Carolina at Charlotte Assistant Professor of Bioinformatics Abigail Leavitt LaBella has co-led an ambitious research study -- published in the widely influential journal Science -- that reports intriguing findings made through innovative artificial intelligence analysis about yeasts, the small fungi that are key contributors to biotechnology, food production and human health. The findings challenge accepted frameworks within which yeast evolution is studied and provide access to an incredibly rich yeast analysis dataset that could have major implications for future evolutionary biology and bioinformatics research.
LaBella, who joined UNC Charlotte's Department of Bioinformatics in the College of Computing and Informatics as an assistant professor and researcher at the North Carolina Research Campus in 2022, conducted the study with co-lead author Dana A. Opulente of Villanova University. They collaborated with fellow researchers from Vanderbilt University and the University of Wisconsin at Madison, along with colleagues from research institutions across the globe.
This is the flagship study of the Y1000+ Project, a massive inter-institutional yeast genome sequencing and phenotyping endeavor that LaBella joined as a postdoctoral researcher at Vanderbilt University.
"Yeasts are single-celled fungi that play critical roles in our everyday lives. They make bread and beer, are used in the production of medicine, can cause infection, and as close relatives to animals have helped us learn about how cancer works," said LaBella. "We wanted to know how these small fungi have evolved to have such an incredible range of functions and features. With the characterization of over one thousand yeasts, we found that yeasts do not fit the adage 'jack of all trades, master of none.'"
This study contributes to basic understanding of how the microbes change over time while generating more than 900 new genome sequences for yeasts -- many of which could be leveraged in biofungal fields such as agricultural pest control, drug development and biofuels production.
LaBella and her co-authors -- through an artificial intelligence-assisted, machine-learning analysis of the Y1000+ Project's dataset comprising 1,154 strains of the ancient, single-cell yeast Saccaromycotina -- attempted to answer an important question. That is: Why do some yeasts eat (or metabolize) only a few types of carbon for energy while others can eat more than a dozen?
The total number of carbon sources used by a yeast for energy is known in ecological terms as its carbon niche-breadth. Humans also vary in their carbon niche breadth -- for example, some people can metabolize lactose while others cannot.
Evolutionary biology research has supported two key overarching paradigms about niche breadth, the phenomenon explaining why some yeast organisms ("specialists") evolve to be able to metabolize only a small number of carbon forms as fuel while others ("generalists") evolve to be able to consume and grow on a broad variety of carbon forms. One of these paradigms illustrates that being a generalist comes with certain trade-offs compared to being a specialist. Notably, in the latter case, the ability to process a wide range of carbon forms comes at the expense of the yeast's capacity to process and grow on each carbon form efficiently. The second is that these yeast specialists and generalists evolve to fit either profile due to the combined effects of different intrinsic traits of their respective genomes and different extrinsic influences based on the varying environments in which yeast organisms exist.
LaBella and her colleagues found ample evidence supporting the idea that there are identifiable, intrinsic genetic differences in yeast specialists versus generalists, specifically that generalists tend to have a larger total number of genes than specialists. For example, they found that generalists are more likely to be able to synthesize carnitine, a molecule that is involved in energy production and often sold as an exercise supplement.
But unexpectedly, their research found very limited evidence for the anticipated evolutionary trade-off of a yeast's ability to process many forms of carbon coming at the expense of its ability to do so efficiently and grow accordingly, and vice versa.
"We saw that the yeasts that could grow on lots of carbon substrates are actually very good growers," said LaBella. "That was a very surprising finding to us."
While the findings of this specific experiment and the innovative machine-learning mechanisms used in its analysis could have major implications for bioinformatics, ecology, metabolics and evolutionary biology, the publishing of this study means that the Y1000+ Project's massive compendium of yeast data is now available for scholars worldwide to use as a starting point to amplify their own yeast research.
"This dataset will be a huge resource going forward," said LaBella.
