A successful colonoscopy depends heavily on a thoroughly cleansed colon, which allows the gastroenterologist a clear and unobstructed view of the bowel lining. The dietary restrictions leading up to the procedure, particularly the clear liquid diet the day before, can be challenging. Understanding which candies are permissible can make this process more manageable and psychologically comforting, providing a small reward during an otherwise difficult preparation period.
The Fundamental Rule: Clear Colors Only
During the clear liquid diet phase, typically the day before your colonoscopy, the primary rule is to consume only liquids or foods that are transparent or translucent. The same principle applies to candies. Any item that contains red, purple, orange, or dark blue food coloring is strictly prohibited. The dyes from these colors can leave residue in the colon that mimics the appearance of blood or inflammation, potentially leading to misinterpretations or the need for a repeat procedure. Light-colored candies, such as those that are clear, yellow, or green, are generally safe and will not interfere with the test.
Why are certain colors banned?
The reason for avoiding certain colors is based on the food dyes used. For example, red dye, often used in fruit-flavored candies and sports drinks, can linger in the digestive tract and be confused with blood during the examination. This can cause unnecessary concern or lead the physician to take unnecessary biopsies. Green and yellow dyes, however, do not cause the same visual interference and are therefore considered safe. Always read the label carefully to ensure no prohibited colors are listed in the ingredients, even if the final product appears light or clear.
Approved Candies for Your Prep Day
For many, the thought of giving up all solid food is daunting, but having a few permitted sweets on hand can provide a welcome distraction. The key is to stick to simple, clear options without any complex ingredients, fillings, or fibers.
- Clear Hard Candies: Plain, clear hard candies like lemon drops, butterscotch, or peppermint rounds are excellent choices. They dissolve completely and do not contain any problematic dyes. They can also help mask the taste of the bowel prep solution, a common complaint.
- Light-Colored Gummy Bears: Not all gummy bears are off-limits. Yellow or green gummy bears can be consumed, as they are clear and melt into a clear liquid. Be sure to inspect the package for any red, orange, or purple colors, and discard them if present.
- Popsicles and Italian Ices: These can provide a refreshing and hydrating treat. Choose lemon, lime, or other light-colored options, ensuring they contain no bits of fruit or seeds.
Comparison of Colonoscopy Prep Sweets
| Sweets | Allowed Color | Not Allowed Color | Additional Notes |
|---|---|---|---|
| Hard Candy | Clear, yellow, green | Red, purple, orange | Excellent for masking the taste of prep solution. |
| Gummy Bears | Clear (yellow, green) | Red, purple, orange | Ensure no opaque or dark-colored varieties are consumed. |
| Popsicles/Italian Ice | Lemon, lime, clear | Red, purple, orange, blue | Avoid those with fruit pulp, seeds, or chunky add-ins. |
| Jell-O/Gelatin | Lemon, lime, orange (light) | Red, purple, dark blue | Offers a sense of satiety during the clear liquid phase. |
| Sodas | Ginger ale, 7-Up, cola (dark) | Red-colored sodas, bright blue | Cola is acceptable because it is opaque but doesn't have staining dyes. |
The Timing of Candy Consumption
While certain candies are permitted during the clear liquid diet, there are often restrictions on when you can consume them. Most medical facilities will instruct you to stop all food and drink, including clear liquids and candy, a set number of hours before your procedure. This is typically between two and six hours, depending on the specifics of your anesthetic plan. Always adhere strictly to your doctor's instructions to ensure your stomach is completely empty on the day of the procedure. Some sources explicitly state no chewing gum, no candy, no mints in the hours leading up to the procedure.
Beyond Candy: A Holistic Approach
Remember that candy is just a small part of a larger dietary plan. It's important to consume a variety of clear liquids to stay hydrated and maintain energy levels. Along with approved candies, incorporate items like clear broths, apple juice, white grape juice, and tea or coffee (without milk or cream). A complete and successful prep is a collaborative effort between you and your healthcare team. If you have any doubts about a specific food or candy, it is always best to consult your doctor or gastroenterology office for clarification.

Conclusion
While a colonoscopy prep diet is restrictive, it doesn't have to be completely devoid of flavor. By choosing clear, light-colored candies and understanding the timing rules, you can make the process more bearable. The ultimate goal is a clear colon, which gives your doctor the best chance to accurately screen for and prevent serious conditions like colorectal cancer. Adhering to these simple guidelines for candy consumption ensures that you support, not sabotage, this vital health procedure.
