Are you an avocado-lover preparing for a colonoscopy? In this short read, we answer your question “Can I eat avocado before a colonoscopy?” and explain why.
When preparing for a colonoscopy, many people are looking for delicious foods they can consume, which is why people keep asking if they can eat avocado before a colonoscopy?
This is a crucial question because the preparation phase, comprises of two types of diet: the Low Fiber diet and the Clear Liquid Diet. Both diets aim to achieve the same goal (keeping the colon free of fecal matter for your colonoscopy) by employing dietary restrictions, but they are not the same.
The Low Fiber diet comes first. It involves the consumption of foods and drinks low in fiber. This means opting for processed foods rather than whole foods, avoiding fruits and vegetables rich in fiber, and opting for fruits that have been deseeded and skinned.

The Clear Liquid Diet has stricter rules. It involves consuming only foods with a liquid consistency and clear appearance. Needless to say, not many foods and drinks meet these requirements. The clear liquid diet is discussed more extensively in Before Colonoscopy: What Can I Eat on a Clear Liquid Diet?
The dietary restrictions of both diets make many people unsure whether they can eat certain things before a colonoscopy. A question that is commonly asked is: Can I eat Avocado before a colonoscopy?
Can I Eat Avocado Before A Colonoscopy on a Low Fiber Diet?
Unfortunately, the answer to this question is not clear. Colonoscopy preparation guidelines published by health professionals do not always agree on whether avocados are OK before a colonoscopy.
Essentially, the low fiber diet allows the consumption of solid foods that are low in fiber. According to the United States Department of Agriculture 100g of avocado contains 6.8g of fiber which is considered relatively high. However, avocados are also soft and easily digested compared to many other high-fiber foods. Hence, several healthcare providers permit avocados on a low fiber diet, while others recommend avoiding them altogether. Therefore, the answer as to whether you can eat avocados before colonoscopy comes down to your particular healthcare provider and what their guidelines state.
Can I Eat Avocado Before A Colonoscopy on a Clear Liquid Diet?
An avocado is an opaque solid. It is not a clear liquid; therefore, it is not permissible on a clear liquid diet. You may not be able to enjoy avocado on a clear liquid diet, but you can enjoy apple juice, strained lemon juice, or white grape juice.
Conclusion
While some healthcare providers may permit avocados on a low fiber diet, there are others that recommend against eating avocados at all. If you prefer to avoid avocado, some other fruits you can enjoy on a low fiber diet in moderation include bananas, melons, honeydew, and cantaloupe. However, if avocado is a central part of your diet, the best advice is to ask your physician if you are allowed to eat avocado before your colonoscopy.
