The low-mold diet

Getting mold out of your home is only half the battle — mold and mycotoxins can wreak havoc from inside your body too. The low-mold diet works to starve mold and fungus internally while restoring the nutrients mold depletes. Here’s what to avoid, what’s safe, and what actively helps you heal.

Key takeaways
The low-mold diet stops mold and fungus growing inside the body and restores nutrients depleted by mold exposure.
Four food groups to avoid: sugar, grains, packaged & processed foods, and mold- & yeast-containing foods.
Plenty is still on the table — clean proteins, low-carb vegetables, nuts and seeds, and healthy fats.
Because mold inflames the brain, prioritize neuroprotective foods: salmon, egg yolks, cruciferous veg, and blueberries.

While mold itself is not a new problem, the dangers of it are unfolding in more recent years. It is becoming apparent that many symptoms have mold as an underlying cause, especially in those who have a genetic predisposition (those with the HLA-DR gene) to mold illness. Mycotoxins, very simply explained, are poisons from mold, and they have been found to contribute to serious problems, including immune deficiency and sometimes the onset of cancer.1 At our office, we offer a blood test which can confirm mold toxicity.

Why follow a low-mold diet?

There are several components involved in tackling the problem of mold, and all of them need to be addressed. While getting rid of mold in your home or workspace may seem obvious, it is important to remember that mold and mycotoxins can wreak havoc from inside your body as well as outside. Therefore, one necessary element for healing is to follow a low-mold diet. While we know that exposure to mold can cause nutrient deficiencies,2 we also believe in the power of nutrient-dense food to heal. The low-mold diet works to stop mold and fungus from growing inside your body and works to restore nutritional deficiencies caused by mold exposure.

Boycotting mold: what to avoid

There are four major groups of foods to avoid on the low-mold diet:

1. Sugar & sugar-containing foods
Sugar is the perfect food for candida, a yeast that can grow in our gut microbiome. Mold loves a fungal, yeast environment, so sugar provides an environment where mold can thrive.3 If your good gut bacteria have already been damaged by mold exposure, sugar lets candida grow very fast, allowing rapid mold growth as well. Avoid all sugar, including natural sugars (honey, molasses) and high-fructose fruits such as grapes, bananas, and pineapple. Dried fruit should also be avoided.
2. Grains
Grains are a major source of mold-contaminated foods. Research has shown they contain the mycotoxins aflatoxin B1, ochratoxin A, fumonisin B1, deoxynivalenol, and zearalenone.4 Climate change is also likely increasing the mycotoxins present in grains like corn and gluten.5,6 Additionally, gluten is an inflammatory food that can exacerbate an already inflamed body from mold exposure.
3. Packaged & processed foods
Canned, bottled, boxed, and otherwise processed foods often contain sugar and additives that fuel mold growth. Absolutely avoid breakfast cereals, ready-made meals, canned soups, ready-made sauces, soft drinks, and fruit juices.
4. Mold- & yeast-containing foods
Mold is a type of fungus, and all fungi should be avoided — including mushrooms, truffles, and yeast. Cheese is prime real estate for mold; avoid cheeses and sour-milk products like sour cream, and especially cheeses with mold in or on them (brie, camembert, blue cheese, limburger). Many nuts are contaminated with mold (peanuts, cashews) from the warm, humid silos they’re stored in. Also avoid processed and smoked meats, white distilled vinegar and products containing it (apple cider vinegar is fine), alcoholic drinks, and any fermented foods.

Aged cheeses, cured meats, dried fruit, nuts, and wine are common high-mold and high-histamine foods — often the first to reduce on a low-mold plan.

What is safe?

Don’t despair — you can still enjoy many foods that will satisfy. Here’s the split between foods to enjoy in moderation and foods to enjoy freely.

Enjoy in moderation
High-starch vegetables (potatoes, sweet potatoes, squashes)
Legumes (lentils, peas)
Gluten-free grains if tolerated (brown rice, quinoa, buckwheat)
Low-sugar fruits (berries, apples, lemons, limes, peaches, pears)
Enjoy freely
Pasture-raised poultry & eggs; grass-fed beef, lamb, venison (not grain-fed)
Wild-caught fish
Low-carb vegetables (cabbage, broccoli, arugula, asparagus, garlic, cucumbers, peppers)
Organic nuts & seeds (almonds, chia, flax, pecans, pumpkin, sunflower, sesame)
Healthy fats (ghee, coconut oil, coconut milk, extra-virgin olive oil, avocado)

If you’ve gone grain-free for a period, you may want to try a gluten-free grain like brown rice, quinoa, or buckwheat and see how you tolerate it — moderation is key, and if you don’t tolerate them well, avoid them. And remember to “eat the rainbow”: include lots of colorful vegetables to give your body the variety of vitamins and minerals it needs for both healing and function.

To satisfy your thirst, choose filtered water, mineral water, fresh vegetable juice, or non-fruity herbal teas. And while coffee is often contaminated with mold, there are brands that are mycotoxin/mold free — our office provides Purity and Bulletproof coffee for purchase.

Neuroprotective foods

Given the damage mold can do in regard to brain inflammation, it’s important to incorporate foods that serve a neuroprotective function:

  • Wild-caught salmon — contains DHA, an omega-3 essential fatty acid for brain health.
  • Egg yolks (if tolerated) — contain choline, which the body uses to produce acetylcholine, a neurotransmitter necessary for optimal brain and nervous system function.7
  • Cruciferous vegetables — cauliflower, broccoli, kale, and cabbage contain sulforaphane, shown to protect the brain against neurodegenerative diseases.8
  • Polyphenol-rich foods — low-sugar blueberries are powerhouses for brain health, working to protect the brain against damage by neurotoxins such as mycotoxins.9
A note on healing time
The time it takes to heal from mold illness depends on how long you’ve been exposed, what type of mold you’ve been exposed to, and how sensitive you are. You most likely didn’t get sick overnight — all healing takes time. The low-mold diet is one necessary piece alongside removing the source and addressing what mold has done inside the body.

Common questions

What is the low-mold diet?
The low-mold diet is a nutritional approach to mold illness recovery. It works to stop mold and fungus from growing inside your body and to restore nutritional deficiencies caused by mold exposure. It removes foods that feed or contain mold and mycotoxins while emphasizing nutrient-dense whole foods.
What foods should you avoid on a low-mold diet?
There are four major groups to avoid: sugar and sugar-containing foods (including natural sugars and high-fructose fruits); grains (a major source of mold-contaminated foods); packaged and processed foods; and mold- and yeast-containing foods such as mushrooms, cheeses, peanuts and cashews, processed and smoked meats, alcohol, and fermented foods.
What can you eat on a low-mold diet?
Enjoy freely: pasture-raised poultry and eggs, grass-fed meats, wild-caught fish, low-carbohydrate vegetables, many organic nuts and seeds, and healthy fats. In moderation: high-starch vegetables, legumes, some gluten-free grains, and low-sugar fruits like berries, apples, lemons, and pears.
Which foods are neuroprotective during mold recovery?
Because mold can cause brain inflammation, include foods that serve a neuroprotective function: wild-caught salmon (DHA), egg yolks if tolerated (choline), cruciferous vegetables like cauliflower, broccoli, kale, and cabbage (sulforaphane), and polyphenol-rich foods such as low-sugar blueberries.
