Which fruits are included on The Kaufmann Diet? Find out which are the healthiest fruits that you should be enjoying on a regular basis and which ones you should avoid or eat sparingly.

We are generally recommended to include more fruits in our diet; fruits are high in a wide array of phytonutrients, including vitamins, minerals, and antioxidants––many of which you can’t find in other places in the concentrations found in fruits. Fruits are also high in fiber, a nutrient that is often deficient in the diets of many Americans. 

Fruits are included in The Kaufmann Diet, but with some caveat. Of course, on their own, fruits are healthy because they are so nutrient dense. Many varieties of fruits, however, are rich in fructose––a type of sugar. For those combatting a potential pathogenic fungal infection, this is not ideal. Despite the fact that many types of fruits, such as bananas, oranges, and melons, contain a wide array of nutrients, the inherent sugar might make starving yeasts and fungi in the body more difficult. 

Getting started with the Kaufmann Diet

So, particularly on Kaufmann One, the more restrictive version on the the diet, fruit options are slightly limited. They are not, however, eliminated; some fruits which are lower in sugar are encouraged. Some of the healthiest varieties are elaborated upon below. 


Berries include blueberries, blackberries, raspberries, cranberries and strawberries. These fruits are powerhouses of nutrition and very high in antioxidants while remaining low in sugar. These are great fruits to include frequently in The Kaufmann Diet. 

Green Apples

Green apples contain less sugar than their red counterparts; they are high in fiber and make a great, portable snack on The Kaufmann Diet. 


Grapefruits are very low in sugar but high in nutrition; one medium sized grapefruit contains more than the RDA amount of vitamin C. Grapefruit seeds contain powerful anti-fungal nutrients. Grapefruits are a great option for breakfast. 

Lemons & Limes

Lemons and limes, like grapefruit, are high in vitamin C. These fruits are very low in calories, but high on flavor; lemon and lime juice bring lots of bright flavors and can be squeezed over everything from salads, to chicken, to fish, added to soups, salsas or other sauces. 


Tomatoes are rich in a wide variety of nutrition, including the anti-fungal nutrient lycopene. Tomatoes are great to enjoy raw, but cooking tomatoes actually enhances the nutrition therein; making homemade salsa or tomato sauces is a great way to include this delicious and nutritions food into your regimen. 


Avocados are a nutritional powerhouse; packed with health mono-unsaturated fats, potassium and fiber, avocados are a nutrient-dense, delicious powerhouse to include in your diet regularly. 

After a period of time on The Kaufmann Diet, you are encouraged to include more fruit in your diet, albeit in moderation. The taste test is the best metric for which fruits should be included in the most moderate amounts; fruits like bananas and oranges contain quite a bit of sugar, and should be enjoyed sparingly. If you start to notice symptoms start creeping in, revert to the more restrictive version of The Kaufmann Diet which includes less fruit.
