Could You Be Struggling with Fructose Malabsorption?
Not sure? Take a look at the symptoms below:
- Nausea
- Bloating
- Excess gas
- Abdominal pain
- Diarrhea
- Vomiting
- Chronic fatigue
- Iron deficiency
- Brain fog
- Depression
- Mood swings

If you answered yes to several of these, you may be dealing with fructose malabsorption—a common but often overlooked digestive issue.
What is Fructose Malabsorption?
Fructose is a simple sugar (monosaccharide) found naturally in many fruits and vegetables, as well as in honey, agave, and a wide range of processed foods containing added sugars. Since the 1970s, fructose consumption has skyrocketed—by more than 1000% between 1970 and 1990 alone. As our intake has increased, so too has the prevalence of fructose malabsorption and intolerance.
When your body struggles to properly absorb fructose in the small intestine, it ferments in the colon instead—causing uncomfortable and sometimes debilitating symptoms.
What About Hereditary Fructose Intolerance (HFI)?
HFI is a separate, more serious genetic disorder in which the body lacks the enzyme needed to break down fructose. It’s typically diagnosed in infancy, especially when babies begin eating formula or solid foods. HFI can cause severe complications such as liver damage and must be medically managed.
What Causes Fructose Malabsorption?
Fructose malabsorption is surprisingly common—affecting roughly 1 in 3 people, with a higher incidence in those with blood type O or B. It occurs when the transporters (called GLUT-5) in the intestinal cells fail to effectively absorb fructose.
Common contributing factors include:
- Gut dysbiosis (an imbalance of good vs. bad gut bacteria)
- Candida overgrowth or frequent antibiotic use
- Diets high in refined or processed foods
- Chronic inflammation
- Pre-existing gut conditions such as IBS, Crohn’s disease, Colitis, or Celiac disease
- High levels of stress
- Being on a gluten-free diet but still experiencing symptoms
What Can You Do About It?
The first step is to reduce or eliminate high-fructose foods from your diet.
Foods to Avoid:
- Sodas and sugary drinks
- Breakfast cereals and cereal bars
- High-fructose fruits like:
- Apples
- Pears
- Watermelon
- Cherries
- Plums
- Peaches
- Prunes
- Fruit juices (especially apple and pear)
- Honey and agave
- Sugar snap peas
- Processed desserts (cookies, candies, ice cream)
Fructose on Labels: What to Watch For
Fructose hides behind many names in processed food labels. Be cautious of ingredients such as:
- High-fructose corn syrup (HFCS)
- Agave nectar
- Crystalline fructose
- Fructooligosaccharides (FOS)
- Sorbitol
- Sugar alcohols
- Honey
- Corn syrup solids
