Fruit and Sugar Combo Intolerance - Expert Advice
The Carroll Food Intolerance Test results prove I’m intolerant to the fruit and sugar combo. This means I cannot digest fruit and sugar eaten together within four hours. Allergy testing never revealed any food combinations as an issue, although I experienced on-going allergy reactions. Many are intolerant to the fruit and sugar combo.
Therefore, advice from Carroll Method naturopathic doctors (NDs) is to avoid the combination of fruit with reactive sugars. These foods may be eaten separately, but should always be kept at least four hours apart. No food should be eaten if it contains both of these. These NDs identify the foods and ingredients that include fruit and sugar. You may be surprised by several items on these lists.
List of Foods Containing Fruit
My Carroll Method ND’s specific instructions about fruit:
Fruit means all apples, pears, berries, lemon, oranges and other fruits, raw, cooked, or dried. Also, all products made from fruit, such as wine, wine vinegars, apple cider vinegar, fruit liquors, citric acid, acetic acid, cranberries, coconut, coconut sugar, avocado, dates, date sugar, cashews, allspice, cloves, balsamic vinegar, bergamot, cream of tartar, olives, papaya, palm, and all oils, barks, peels, etc. from these fruits. This includes any food cooked or flavored with fruit or fruit extracts. Italian wines are considered fruits. It is illegal in Italy to add sugar during the termination process.
Fruit does not include pineapple (cactus), melons (gourds), monk fruit, tomatoes, and rhubarb which are vegetables.
List of Foods Containing Reactive Sugars
My Carroll Method ND’s specific instructions about sugar. These are reactive sugars that cause intolerant reactions when mixed with fruit.
Reactive Sugar means white, brown, turbinado and raw sugar, molasses, sucrose, sucralose, sucanat, dried cane juice, evaporated cane juice, or any sugar cane (even organic), or sugar beet product. Do not use artificial sweeteners, such as saccharine or NutraSweet. Rum and most wines contain sugar.
List of Foods Containing Neutral Sugars
Neutral sugars can be combined with fruit and do not drive reactions for most.
Neutral sugar means agave, honey, maple sugar and syrup, date sugar, coconut sugar, and barely malt (not for the gluten intolerant).
If you have this combination intolerance, test yourself by eating fruit and neutral sugars on an empty stomach and monitor reactions. Do not bake with honey.
Fruit and Sugar Combo Intolerance - My Pro Tips
Finally, I am following my favorite experts advice and cutting all reactive sugars. The neutral sugars are even more enjoyable than reactive sugars. High glycemic foods cause digestion issues, inflame my body and itchy feet. A plus, neutral sugars have lower glycemic indexes.
I need four hours to completely digest fruit or sugar per the Carroll Method. Some may need more time, up to eight hours, between fruit and sugar for proper digestion.
The fruit and sugar combination intolerance is an area full of pitfalls. Not a lot of information is available. Of course, there would be no pitfalls if reactive sugars are eliminated sugar completely. Many experts recommend cutting sugar, especially for gut healing. Cutting all reactive sugar is great advice for everyone.

Some need four hours between fruit and sugar, some up to eight hours. Do a test, eat fruit combined with sugar on an empty stomach.
