Sweet Potatoes and The Kaufmann 2 Diet

Print Friendly, PDF & Email

Generally, on the show and on our blog, you will hear more about the Kaufmann 1 Diet than the Kaufmann 2 Diet, because the Kaufmann 1 Diet is the foundation of much of what we talk about when it comes to maintaining good health. The Kaufmann 1 Diet is meant to be more of a lifestyle than a short term diet. It is, however, fairly restrictive; the Kaufmann 1 Diet eliminates sugar, grains, corn, most starchy carbohydrates, the sweeter varieties of fruit, yeast and foods made with yeast, peanuts, pistachios, alcohol, legumes, most dairy and most processed food. These restrictions eliminate what many people’s daily diets consist of!

These restrictions are geared to address two primary issues, which are pathogenic fungal infections and the possible presence of mycotoxins in parts of our food supply. Fungal infections––which can cause a variety of human health problems, but are difficult and rarely diagnosed––thrive when the host’s diet is high in sugar and carbohydrates. Furthermore, many parts of our food supply are contaminated with fungal toxins, known as mycotoxins, which are among the most toxic, naturally occurring chemicals on planet earth.


The Kaufmann 1 Diet seeks to address the issues in the most efficient, dietary way possible. However, for those perhaps not experiencing any serious health issues, the transition to the more life-style friendly and less restrictive Kaufmann 2 Diet is a good option.

The Kaufmann 1 Diet is less restrictive: it allows for legumes (peanuts are still to be avoided), more fruit, and certain grain products, all in moderation. One other food allowed on The Kaufmann 2 Diet is the sweet potato.

Potatoes in general are disallowed on the Kaufmann 1 Diet, because of their carbohydrate/sugar content. The Kaufmann 2 Diet makes an exception for sweet potatoes because of their excellent nutritional content. Sweet potatoes are excellent sources of fiber, and phytonutrients, particularly vitamin A (Beta Carotene). Sweet potatoes are a great source of antioxidants and may have blood sugar regulating and anti-inflammatory properties. Many of the nutrients inherent in sweet potatoes exhibit anti-fungal properties, as well.

If at any point, you experience health problems or suspect you have a fungal infection, it may be beneficial to revert back to the more restrictive Kaufmann 1 Diet. While the sugar and carbohydrate content in sweet potatoes is high, feel free to enjoy in moderation when transitioning to the Kaufmann 2 Diet; these tubers are available year round at most grocery stores, and while they have the added benefit of being delicious, they contain even more benefits for your health. Add a small bit of fat or oil to your meal when you enjoy sweet potatoes to maximize their nutrient absorption.
