Will going on a yeast free diet cure my fructose intolerance?

I am fructose intolerant which is when you can't absorb fructose a sugar found in fruit. I have yeast overgrowth in my intestines and just started the yeast free diet today. Do you think there is any hope that the yeast infection could be causing the fructose intolerance by messing with the intestines ability to properly make enzymes. I'm desperate to eat fructose again and am going out on a limb here. Do you think I have a prayer?

From the research I've done, fructose intolerance rings in at about 1% with yeast as the culprit. It is worth a shot to try, but this is a very strict diet. While it may not cure the fructose intolerance, it might help you in other aspects of your life, such as with mood swings, fatigue, etc.  (+ info)

Diagnosed with fructose intolerance. How accurate do you think these tests are?

Do you think the tests is accurate? Has anyone had the test and gotten better when eliminating fructose from your diet?

Hey I'm fructose intolerant. I eliminated fructose completely from my diet and my stomach got 10 times better really fast. Same with lactose. See i'm fructose and lactose intolerant and intolerant to all sugars that end in OL (like sorbitol) I also had a hydrogen breath test where they give me fructose and i have to blow air into a bag every 30 minutes for three hours. Which came back positive. All tests are really accurate and it isn't that bad being fructose intolerant.
Hope I helped (:  (+ info)

Does anyone have food suggestions for fructose intolerance?

I was recently diagnosed with fructose intolerance and I'm having a hard time finding stuff to eat. It is very hard because I have a big sweet tooth. Any suggestions would be great!

What is Hereditary Fructose Intolerance?

What is hereditary fructose intolerance? Is it rare? What foods do you have to avoid? How can you tell if you have it?

Hereditary fructose intolerance is a disorder of metabolism in which a person lacks the protein needed to break down fructose. Fructose is a fruit sugar that naturally occurs in the body. Man-made fructose is used as a sweetener in many foods, including baby food and drinks.

Fructose intolerance is an inherited disorder passed on to children through their parents' genes. Both the mother and father have the gene that causes the condition, but may not have symptoms of fructose intolerance themselves. (This is called an autosomal recessive pattern of inheritance.) The disorder will not be apparent until the infant is fed formula, juice, fruits, or baby foods that contain fructose. Initial symptoms include vomiting, dehydration, and unexplained fever. Other symptoms include extreme thirst and excessive urination and sweating. There will also be a loss of appetite and a failure to grow. Tremors and seizures caused by low blood sugar can occur. The liver becomes swollen and the patient becomes jaundiced with yellowing of the eyes and skin. Left untreated, this condition can lead to coma and death.

Fructose is a sugar found naturally in fruits, vegetables, honey, and table sugar. Fructose intolerance is a disorder caused by the body's inability to produce an enzyme called aldolase B (also called fructose 1-phosphate aldolase) that is necessary for absorption of fructose. The undigested fructose collects in the liver and kidneys, eventually causing liver and kidney failure. One person in about 20,000 is born with this disorder. It is reported more frequently in the United States and Northern European countries than in other parts of the world. It occurs with equal frequency in males and females.

Fructose is a sugar found in fruit. It's also a basic component in table sugar (sucrose). In addition, sorbitol — a sugar alcohol — is converted to fructose during normal digestion. So if you have fructose intolerance, you should avoid foods that contain fructose and sucrose as well as sorbitol. These include:

Fruit and fruit juices
Meat products cured in sugar or breaded
Sweetened milk or sweetened milk beverages
Maple syrup
Corn syrup
Table sugar (beet and cane)
Confectioner's sugar
Some vegetables as well as some bread and cereal products also may contain fructose.

Consult a registered dietitian for a complete list of foods you 0r your child should eat or avoid. The dietitian also can help create a healthy diet plan for you or your child to make sure that your diet contains the nutrients needed for a healthy diet.

It is important to note that "fructose intolerance" is a general term that describes two possible conditions:

Hereditary fructose intolerance, a rare genetic disorder. People with hereditary fructose intolerance lack an enzyme that breaks down fructose. This is a serious disorder that can lead to liver and kidney damage.

Fructose malabsorption, a digestive disorder. People with fructose malabsorption have difficulty digesting fructose. This is a less serious disorder because it doesn't result in liver or kidney damage. But it can cause abdominal pain, nausea, bloating and diarrhea.

Either condition should be confirmed by a doctor using reliable testing methods.


Commonly, diagnosis is confirmed by urine tests used to detect fructose sugar in the urine. Blood tests can also be used to detect hyperbilirubinemia and high levels of liver enzymes in the blood. A liver biopsy may be performed to test for levels of enzymes present and to evaluate the extent of damage to the liver. A fructose-loading test where a dose of fructose is given to the patient in a well-controlled hospital or clinical setting may also be used to confirm fructose intolerance. Both the biopsy and the loading test can be very risky, particularly in infants that are already sick.

Carriers of the gene for hereditary fructose intolerance can be identified through DNA analysis. Anyone who is known to carry the disease or who has the disease in his or her family can benefit from genetic counseling. Since this is a hereditary disorder, there is currently no known way to prevent it other than assisting at-risk individuals with family planning and reproductive decisions.

Can yeast overgrowth cause fructose intolerance?

I have fructose intolerance which is when you can't absorb fructose a type of sugar found in fruit and vegetables. I have intestinal yeast overgrowth and was wondering if it could be messing with my intestines ability to make the enzyme needed to digest fructose. Fructose is in almost everything and I'm desperate to be a normal person again. Do you think once I get rid of this infection that maybe I'll be able to eat fructose again? Do I have any hope???

Its largely genetic (which oddly as it sounds, is NOT to be confused with hereditary fructose intolerance - which is a liver problem, not an intestinal issue)...

I actually suspect that its the other way around, that the intestinal condition makes you predisposed to other opportunistic infections, yeast being one of them...  (+ info)

How many people die from "Hereditary Fructose Intolerance" each year?

It's for my project! THNXS!!


Absolute elimination of fructose and glucose produces good results in most children with fructose intolerance. A few children will go on to develop progressive liver disease. The prognosis depends on how soon the diagnosis is made and how soon fructose and sucrose can be eliminated from the baby's diet.

In infants, the disease is generally fatal before age 2. Patients with a later onset form of the disease have a milder course of the disease and live significantly longer.  (+ info)

How does fructose intolerance affect you?

what products containing sorbitol exacerbate the problem

Are you sure you aren't gluten intolerant? Or have Celiac Disease? Fructos is just sugar. Anything ending in "itol" is sugar. Many of them do cause diarehha, bloating and gas. In my opinion all fake sugars are bad for you. See the website www.sweetpoison.com for more info.
For more info on Celiac Disease see links below.  (+ info)

Is burping a symptom of Wheat/Lactose/Fructose Intolerance?

probably, because i have lactose intollerance, and it causes gas-which burping is a form of. also, keep a look out if it causes cold like symptoms- thats what it did to me. you could try not eating what you usually do with the dairy product or whatever, and see if that reduces the burping. hope im of any help  (+ info)

Does anyone have any main meal recipes for people with Fructose Intolerance/Malabsorption ?

I found, for sale, the world's first Frut/Mal cookbook at the following site, which hopefully is helpful :)


I also stumbled upon the following support group for people with Fructose Intolerance, and believe that this question could be answered on one of the topic boards, by others who live with this, and have real-life ideas.


Good Luck with everything.. and I hope this helps :)  (+ info)

I am fructose intolerance-- is sucrose ok?

I have recently found out that I am fructose intolerance. I have to eliminate all fructose in my diet in order for my chronic pain to leave. The dietician gave me a list of foods that I can and can't eat, and sucrose (table sugar) was allowed. However, I was looking on many medical websites, and they said that you should stay away from sucrose. Does anyone know if I can or can't eat it? Thanks!

nope...sucrose is the combination of fructose and glucose at a 1:1 ratio  (+ info)
