What Food at a Barbeque Might Teach You about CSID

If you have Sucrose Intolerance caused by Congenital Sucrase-Isomaltase Deficiency (CSID), foods containing high levels of sucrose (table sugar) trigger unpleasant gastrointestinal (GI) symptoms. In addition to complicating your day-to-day eating habits, enjoying a seasonal barbeque is no picnic.

From corn on the cob, grilled onions, and juicy watermelon wedges to peak-season cantaloupe, old-fashioned bean salad, and gooey brownies, barbeque foods are a delicious way to enjoy and celebrate the season.

Unfortunately, with CSID, your body lacks the compound enzyme (a protein), sucrase-isomaltase, that is produced in the small intestine. This enzyme is needed to properly digest foods containing a natural or added sugar called sucrose. A common name for sucrose is table sugar, but it occurs in many foods. Consequently, indulging in seasonal summer favorites that contain sucrose can make you feel ill.

If you have CSID, you can experience symptoms such as gas and bloating, abdominal pain, or diarrhea after eating some of your favorite foods.

Without sucrase-isomaltase on board, your body can’t properly break down foods containing sucrose into glucose and fructose, which are forms of sugar your body can absorb and use for fuel.

Foods to Avoid at a Barbeque

Typical barbeque foods most people with CSID can’t tolerate include:

  • Savory salads containing beans or lentils
  • Grilled sweet potatoes
  • Green peas
  • Grilled or raw onions
  • Corn on the cob
  • Condiments like barbeque sauce
  • Fruit salads with apples, apricots, bananas, peaches, pineapple, tangelos, and tangerines
  • Cantaloupe
  • Desserts, such as brownies, cookies, and cakes
  • Sweetened sodas

Foods You Can Eat at a Barbeque

Although restricting your diet won’t fully relieve your CSID symptoms, it’s helpful to know which items people with CSID can generally tolerate well:

  • Plainly prepared grilled meats, without sweet sauces such as barbeque sauce
  • Fruit salads with blueberries, strawberries, cherries, figs, raspberries, kiwi, and blackberries
  • Vegetable salads with asparagus, broccoli, bok choy, brussels sprouts, cauliflower
  • Garden salads with lettuce, spinach, mung bean sprouts, cucumbers, mushrooms, radishes, tomatoes, and peppers
  • Grilled zucchini or summer squash
  • Guacamole
  • Water, including seltzer

Get Diagnosed While Still Enjoying the Season

If you notice symptoms, such as gas, bloating, diarrhea, or abdominal pain after consuming these typical summer barbeque foods, you may have CSID. Consulting with your physician, keeping a food diary, and taking this quiz will all be beneficial steps on your path to a diagnosis.
