Fungus-Link-Vol1Gut health has been all the rage for years, and subsequently there is a lot of advice about how to support your gut. This is both a good and a bad thing; certainly, good gut health is essential to protecting overall health. This if fundamental to The Kaufmann Diet––if there are harmful yeast and fungi thriving in the gut, it can be really hard to improve your overall health. 

The downside of all the gut health advice is that many practitioners miss the fungal link to gut problems, which is likely far more widespread than many imagine. This is due to a diet high in sugar and refined carbs, frequent antibiotic usage, and other factors common in western lifestyle. 

The worst foods for gut health are those that can disrupt the balance of your gut microbiome, cause inflammation, and contribute to digestive problems. Frequently, you are going to hear to avoid these types of foods:

Processed Foods: Highly processed foods often contain additives, preservatives, and artificial ingredients that can negatively affect the gut. They are also typically low in fiber and high in unhealthy fats and sugars.

Artificial Sweeteners: Some artificial sweeteners, like aspartame, sucralose, and saccharin, can negatively impact the gut microbiome and lead to metabolic disturbances.

Trans Fats: Trans fats, often found in fried and processed foods, can promote inflammation and harm gut health.

Alcohol: Excessive alcohol consumption can harm the gut lining, disrupt the balance of gut bacteria, and lead to inflammation.

Artificial Additives: Some food additives, such as emulsifiers and artificial colors, may negatively affect the gut microbiome and contribute to inflammation.

This is all good advice, and things you would be avoiding anyway on The Kaufmann Diet. What many people miss is that there are other foods that might be damaging your gut, due to contamination with mold, yeast, fungi, or the poisons they leave behind, called mycotoxins. Foods high in sugar also feed yeasts in the gut, exacerbating the problem.

Getting started with the Kaufmann Diet


Some other foods you should avoid if you want to promote your gut health include:


Corn is universally contaminated with low levels of mycotoxins. Any corn derivatives are at risk too, including corn syrup, corn starch, etc. 


Wheat is commonly contained with mycotoxins. Wheat, especially in the form of refined flour, is also high in simple carbohydrates, which can contribute to yeast problems. 

High Sugar Foods

Of course, this includes sweets, candy, sugar itself, etc., but it can also mean foods high in simple carbohydrates (i.e., pasta, bread), but even high sugar fruits like bananas and melons can be problematic for people with gut yeast problems. 


Peanuts are commonly contained with mycotoxins; this includes peanut butter. 

Anything Containing Yeast or Fungi

Think, breads, moldy cheese, alcohol, or any of the other foods made using yeast or fungal products. These should certainly be avoided on an anti-fungal program.
