OUR STORY

Sucrose Intolerance Awareness Week - 4 Myths Busted

To celebrate Sucrose Intolerance Awareness Week, here are four health myths about the disease, debunked. Flip the card to reveal the truth!

Myth

It’s easy to diagnose sucrose intolerance.

Truth

Sucrose intolerance is tricky to diagnose. Many of the symptoms - like bloating, gas, stomach pain after eating, diarrhea, and constipation - are also present in other conditions like irritable bowel syndrome.

Myth

You can see how much sucrose is in foods by reading the nutrition facts chart.

Truth

The nutrition facts chart shows the exact amount of sugar in grams. That ``sugar`` can include sucrose, lactose (milk sugar), fructose (fruit sugar), glucose, maltose (a simple sugar broken down from starch), and galactose (a simple sugar broken down from lactose). You can only tell what kind of sugar is in a food by reading the ingredient list.

Myth

You'll just grow out of it.

Truth

Sucrose intolerance is caused by a genetic mutation present from birth. Babies with the disease may not show symptoms until they start consuming formula or solid foods. Symptoms may become less severe in adults, but it's not possible to just grow out of the disease.

Myth

The low-FODMAP diet can reduce symptoms of sucrose intolerance.

Truth

The low-FODMAP diet was developed for people with irritable bowel syndrome. It is not recommended for people with sucrose intolerance because it's not a low-sucrose diet. People with sucrose intolerance who follow a low-FODMAP diet may still experience uncomfortable symptoms.

#SucroseIntoleranceAwareness

Celebrate National Sucrose Intolerance Week the first week of April to raise awareness about the unmet needs of people living with the condition.

People who have sucrose intolerance suffer from abdominal pain, gas, bloating, and diarrhea because they lack sufficient digestive enzymes to properly digest sucrose (table sugar) and starch found in many foods.
