Fructose intolerance: symptoms, what to eat and which foods to avoid, diagnosis and who to contact in case of suspected intolerance.

L'fructose intolerance it is a condition of intolerance of our organism towards sugar which is mainly contained in fruit, and which can also be found in a long series of food products - foods and drinks - as a sweetener.

It follows that to be fructose intolerant it means having to contend with potential limitations of one's diet to a wide range of "menus". But what are the symptoms? How is fructose intolerance diagnosed? And how to behave in this case?

Symptoms of fructose intolerance

Regarding i symptoms of fructose intolerance, it is clear that these only occur when foods containing this sugar are introduced into one's diet.
Even then, however, it is difficult to try to generalize the signs of this condition of intolerance, given that each patient could react differently to this scenario. Some people may therefore experience vomiting and diarrhea, and long-term hypoglycemia, liver and kidney damage, and so on. Other people, on the other hand, experience these symptoms in a much milder way.

Fructose intolerance: analysis and diagnosis

There diagnosis of fructose intolerance it mainly occurs with a physical examination, from which it is possible to detect a possible enlargement of the liver and spleen. Even the skin, with its complexion, could provide a useful “spy” for your doctor: a shade characterized by a fair pallor could in fact identify the need to investigate one's condition through specific tests that can confirm or not the diagnosis.
As far as these analyzes are concerned, we mainly refer to blood clotting tests, enzyme studies, and again to genetic tests and those on kidney and liver function, together with blood sugar level tests and blood tests. uric acid and urine. Only in a few cases is a liver biopsy required.

Diet: what to eat in case of fructose intolerance?

But what can you eat with fructose intolerance? Evidently, theoretically, a person intolerant to fructose should avoid taking all those foods that contain it.

Which, in the end, means being able to eat meat, eggs and fish without problems (at least, limited to this condition of intolerance). On the other hand, some attention must be paid to milk and its derivatives, with the exclusion of sweetened powdered milk, dairy products and sugary yogurt from one's diet, to be replaced perhaps with fresh cheeses.

Another rather important limitation is that related to fruit, fresh and dried. On the other hand, a wide range of legumes and vegetables, such as beans, spinach, lentils, chickpeas or soy, can be introduced into one's diet without particular problems. Instead, avoid carrots, tomatoes, artichokes, asparagus and beets.

And the flour? Bread, pasta and pizza

As far as flour products are concerned, there are no particular preclusions, as long as all products based on sugary industrial flours are excluded. Better then to draw on products based only on natural flours, such as wheat and oats, barley and corn, rye and rice.

Compatibly with the above we have had the opportunity to summarize, we should finally pay great attention to condiments that are sweetened and to common sugar, such as sucrose. On the other hand, glucose and lactose are allowed, considering that the intolerance is to fructose, an element obviously different from the components just mentioned.

Suspected fructose intolerance?

As always, we have the opportunity to clarify, in case of suspected fructose intolerance, our suggestion can only be to invite you to speak specifically with your family doctor and, subsequently, with a dietician.

They will allow you not only to arrive at the certainty of a diagnosis (which can confirm suspicions of fructose intolerance or, conversely, exclude this cause from the list of determinants of your health states), but also - in the hypothesis of ascertained intolerance - the structuring of a new dietary path that will allow you to overcome any discomfort felt, obtaining all the nutrients you need but, on the other hand, without suffering the negative consequences deriving from the intake of some food that could trigger the symptoms of intolerance.
