The Importance of Fibre in Starchy Foods
Starchy foods are often misunderstood, but they are a crucial part of a healthy diet, providing the body with its main source of energy. The key is choosing the right types. While refined starchy foods like white bread and pasta are stripped of their fibre during processing, their whole-grain counterparts and other natural sources retain this vital nutrient. Dietary fibre is a non-digestible carbohydrate found in plant-based foods that plays a critical role in digestive health, weight management, and maintaining stable blood sugar levels.
Fibre-Rich Whole Grains and Cereals
Whole grains are the cornerstone of a fibre-rich diet. Unlike refined grains, they contain the entire grain kernel—the bran, germ, and endosperm—all packed with fibre, vitamins, and minerals. Choosing whole-grain options is a straightforward way to increase your daily fibre intake. Oats, for example, are a powerful source of soluble fibre, which helps lower cholesterol and promotes good gut bacteria. Whole wheat bread, pasta, and cereals are also excellent choices, provided you opt for the whole-grain variety over refined versions. When shopping for breakfast cereals, look for options like plain shredded whole grain or bran flakes, which are high in fibre.
Legumes and Beans: Starchy Superfoods
Legumes and beans are a phenomenal, and often overlooked, source of starchy fibre. This category includes a wide variety of versatile foods that can be added to countless meals. Lentils are particularly high in fibre, as are black beans, kidney beans, and chickpeas. The fibre in legumes consists of both soluble and insoluble types, which provides a range of benefits from promoting regular bowel movements to slowing down digestion and increasing feelings of fullness. Adding pulses like lentils or chickpeas to soups, curries, and salads is an easy way to boost your fibre intake.
Starchy Vegetables That Pack a Punch
Not all vegetables are created equal in the starch and fibre department. Some starchy vegetables are particularly rich in fibre and should be a regular feature in your meals. Potatoes, especially when eaten with their skin on, are a great example. The skin contains a significant amount of fibre that is often discarded. Other high-fibre starchy vegetables include corn, peas, and parsnips. Sweet potatoes and butternut squash also contribute valuable fibre and nutrients to your diet. Cooking and then cooling certain starchy vegetables, like potatoes, can also create resistant starch, a type of fibre that feeds healthy gut bacteria.
The Role of Resistant Starch
Resistant starch (RS) is a type of starch that is not digested in the small intestine but instead ferments in the large intestine, behaving much like soluble fibre. This process provides nourishment for beneficial gut bacteria and can aid in blood sugar control and weight management. Foods like legumes, whole grains, and starchy vegetables (after cooking and cooling) are key sources of resistant starch. Examples include cooked and cooled rice or potatoes, lentils, and oats. Incorporating these items into meal preparation can provide an extra digestive boost.
Comparison of Common Starchy Foods
| Food Item | Fibre Content (High/Low) | Primary Fibre Type | Best Preparation Method for Fibre | Refined vs. Whole |
|---|---|---|---|---|
| Brown Rice | High | Insoluble | Boiled or steamed | Whole |
| White Rice | Low | N/A | Boiled or steamed | Refined |
| Whole Wheat Pasta | High | Insoluble & Soluble | Boiled (al dente) | Whole |
| Standard White Pasta | Low | N/A | Boiled | Refined |
| Baked Potato (with skin) | High | Soluble & Insoluble | Baked, boiled (with skin) | Whole |
| French Fries | Low | Insoluble (less) | Fried | Refined |
| Lentils | High | Soluble | Boiled, used in stews | Whole |
| White Bread | Low | N/A | Toasted or untoasted | Refined |
| Oats (Porridge) | High | Soluble | Cooked, overnight oats | Whole |
Practical Tips for Increasing Fibre Intake
Boosting your intake of high-fibre starchy foods doesn't have to be complicated. Start with small, manageable swaps. Trade your morning white toast for a slice of whole-grain or seeded bread. Instead of white rice with your dinner, use brown rice or bulgur wheat. For pasta dishes, simply switch to a whole-wheat variety. Leave the skin on your baked potatoes or make your own oven-baked potato wedges. For snacks, consider making homemade popcorn (a whole grain) or eating oatcakes with a healthy topping. When making soups, stews, or salads, add a handful of beans or lentils for extra fibre and bulk.
Potential Side Effects and How to Manage Them
When increasing your fibre intake, it's wise to do so gradually. A sudden, large increase can cause bloating, cramping, or gas. Give your digestive system time to adjust. It's also crucial to drink plenty of fluids, especially water, as fibre absorbs water and needs it to move through your system efficiently. A gradual approach combined with proper hydration will help you reap the benefits of a high-fibre diet without discomfort. For those with medical concerns, consulting with a healthcare professional or registered dietitian is always recommended before making significant dietary changes.
Conclusion
To answer the question, what starchy foods have fibre in them, the most straightforward answer is to look for whole-grain and minimally processed versions. From whole-wheat bread and pasta to brown rice, legumes, and potatoes eaten with their skins on, numerous starchy foods are excellent sources of dietary fibre. Incorporating these foods into your daily meals offers significant benefits for digestive health, satiety, and overall well-being. By making simple, conscious choices, you can easily increase your fibre consumption and enjoy the satisfying, health-boosting power of starchy foods.

Frequently Asked Questions
What are some of the highest-fiber starchy foods? Some of the highest-fiber starchy foods include lentils, black beans, whole grains like oats and brown rice, and potatoes with their skin on.
Is whole wheat pasta a good source of fibre? Yes, whole wheat pasta is a good source of dietary fibre, as it contains more fibre than its refined white flour counterpart.
Does all bread have fibre? No, not all bread has fibre. White bread is low in fibre, while wholegrain, wholemeal, and seeded breads are excellent sources.
Why should I eat potatoes with their skin on? Eating potatoes with their skin on dramatically increases the fibre content, as the skin contains a significant amount of the vegetable's fibre.
What is resistant starch and which foods contain it? Resistant starch is a type of starch that acts like fibre and is found in foods that have been cooked and then cooled, such as cooked rice, potatoes, and lentils.
Can high-fibre starchy foods help with weight loss? Yes, high-fibre starchy foods can aid in weight loss by helping you feel full for longer, which reduces overall calorie intake.
What is the difference between refined and whole-grain starchy foods? Refined starchy foods have been processed to remove the bran and germ, which also removes much of the fibre and nutrients. Whole-grain starchy foods retain the entire grain kernel, including the fibre-rich bran.
Is brown rice really better than white rice for fibre? Yes, brown rice contains more fibre than white rice because it retains the bran and germ layers, which are stripped away during the processing of white rice.
