A low residue diet is often prescribed by doctors for a variety of gastrointestinal conditions, including inflammatory bowel disease flares or diverticulitis, and as part of preparation for medical procedures such as a colonoscopy. The goal is to give the digestive system a rest by minimizing the amount of undigested material that passes through the large intestine. Since many traditional biscuits contain whole grains, dried fruits, or nuts, which are high in fiber, selecting the right ones can be challenging. This article breaks down the best choices to help you enjoy a snack while adhering to your dietary plan.
Low Residue Biscuit Choices
The key to selecting the right biscuit is to focus on products made with refined white flour and without high-fiber additions. High-fiber ingredients to avoid include whole grains, dried fruits, seeds, and nuts. Instead, look for simple, plain biscuits with a smooth texture.
Some popular and suitable options often include:
- Rich Tea Biscuits: A classic choice, these are made with refined flour and have a simple, light texture.
- Custard Creams: The smooth filling and plain biscuit base make these a safe option, provided they don't contain any high-fiber additives.
- Shortbread: A simple, butter-based biscuit, shortbread typically has very low fiber content.
- Arrowroot Biscuits: These are often recommended on low-residue diets for their easy digestibility.
- Marie Biscuits: Similar to Rich Tea, these are simple and made from refined flour.
- Plain Crackers: Saltines or water biscuits that are white-flour based are also suitable alternatives to traditional biscuits.
- Ginger Nuts: Many plain ginger nut varieties are made with refined flour and are acceptable on this diet.
Why are these biscuits okay?
These biscuits are easy to digest because their ingredients have been processed to remove much of the fiber. The refining process for white flour strips away the bran and germ, leaving only the starchy endosperm, which is easily broken down by the digestive system. This results in less residue passing into the colon, which is the entire purpose of the diet.
Important Considerations and Exclusions
While many plain biscuits are acceptable, it's crucial to be vigilant and read labels carefully. Even some seemingly plain biscuits can contain hidden ingredients that are not suitable for a low residue diet. When in doubt, it is always best to check the fiber content on the nutrition label and ensure it is below 0.5-1 gram per serving.
Common Biscuits to Avoid
- Digestives: Often made with wholemeal flour, digestives are specifically designed to be high in fiber.
- Flapjacks: These are typically oat-based and often contain dried fruit, making them high in fiber.
- Biscuits with Dried Fruit: Fig rolls, garibaldi, or any biscuit containing dried fruits like raisins or currants should be avoided.
- Biscuits with Nuts or Seeds: Products with added nuts, seeds, or coconut are not suitable for a low residue diet.
- Wholemeal or Wholegrain Biscuits: Any biscuit marketed as wholemeal, wholegrain, or high-fiber is inappropriate for this diet.

Other Tips for Your Diet
Beyond just biscuits, remember that adhering to a low residue diet involves limiting many other foods as well. This often includes most raw fruits and vegetables, whole grains, nuts, and legumes. Staying hydrated is also very important, especially with clear fluids like water and non-pulpy fruit juices. Always consult with a healthcare provider or a registered dietitian before starting any new dietary plan, especially if it's for an extended period, as it may lack certain essential nutrients. A healthcare professional can ensure you're meeting your nutritional needs while managing your medical condition.
Conclusion
Navigating a low residue diet doesn't mean you have to give up all your favorite treats. By choosing simple, plain biscuits made with refined white flour, such as Rich Tea, Custard Creams, or Shortbread, you can still enjoy a snack while helping your digestive system rest. The key is to avoid high-fiber ingredients like whole grains, nuts, seeds, and dried fruits, and always double-check the food labels. Remember, this diet is typically a short-term solution, and a healthcare professional's guidance is vital for maintaining a balanced and healthy eating plan during this period.
