Sucrose is a natural sweetener most often called table sugar. There are three main sources of sucrose in the diet:

  • Table sugar added to foods when cooking or baking.

  • Sucrose (table sugar) added to processed foods (hot dogs, sweetened fruit juices, fruit drinks, sodas, canned fruits, ketchup, spaghetti sauces, etc.).

  • Sucrose that occurs naturally in foods (maple syrup, molasses, fruits and vegetables).

Sucrose is broken down in the body by an enzyme named sucrase. Sucrase breaks down sucrose into two simple sugars: glucose and fructose. When a person has low levels or lacks the sucrase enzyme, too much sucrose can build up in the gut. This can cause bloating, gas, abdominal pain, cramping, and diarrhea.

Reactions to sucrose vary. Some people can handle more sucrose in the diet than others. Most people have problems with large amounts of sucrose or a diet high in sugar.

To decrease symptoms, you will need to read food labels. Check labels for sugars, syrup and other foods that have sucrose.

Avoid foods that list sugars as one of the first four ingredients. If you are not sure about the product, contact the company. Most products list a phone number on the label that you can call if you have questions.

You will not need any other nutritional supplements when you follow a low sucrose diet. You will get the nutrients you need by eating a well-balanced diet.

Talk with your doctor or pharmacist about whether your medicines contain sucrose. Many lozenges, cough and vitamin syrups contain sucrose. You may need some medicines to be made for you without sucrose. Allow extra time for this custom order.

Some people will find relief of symptoms quickly while others need more time. You can slowly add foods back into your diet once your symptoms improve. Bring only one new food back into your diet at a time. Wait 2-3 days in between. If you remain symptom-free, add more new foods. If symptoms restart, restrict diet to where you are symptom-free. This will help you determine the amount of sucrose and sucrose containing foods that your body can handle.
