The Fiber Champion: Artichoke Heart
When comparing fiber content cup-for-cup, the cooked artichoke heart consistently emerges as a top performer. A single cup of cooked artichoke delivers a robust 9.6 grams of fiber, providing a significant portion of the recommended daily intake for most adults. In addition to its high fiber count, artichokes offer a wealth of other health benefits. They are an excellent source of magnesium, a mineral vital for regulating blood pressure and supporting bone health. Artichokes also contain antioxidants like cynarin and silymarin, which may support liver health. While consuming the heart is most common, some of the fiber is also found in the meat at the base of the petals.
There are many delicious ways to incorporate artichokes into your diet. They can be steamed, boiled, or grilled and served with a simple vinaigrette. Artichoke hearts can also be used in creamy dips, added to salads, or served as a topping on pizzas. For convenience, frozen or canned artichoke hearts offer a ready-to-use option, making it simple to add this high-fiber vegetable to your meals throughout the week.
Top Fiber Contenders: Other Powerhouse Vegetables
While the artichoke may hold the top spot for fiber per cup, many other vegetables are packed with this essential nutrient. Incorporating a variety of these foods is the best strategy for a well-rounded diet and a healthy gut microbiome.
Cooked Green Peas
For an easy-to-use fiber boost, look no further than cooked green peas. A single cup of boiled green peas provides approximately 9 grams of fiber. They are also a good source of vitamins A, C, and K, as well as protein. Frozen peas are an incredibly convenient option, ready to be added to soups, stews, or side dishes in minutes.
Cooked Lima Beans
Often referred to as butter beans, lima beans are a dense source of fiber. A half-cup serving offers about 9.2 grams of fiber, making a full cup a serious fiber meal. These beans are also rich in protein and iron, making them an excellent choice for plant-based diets. Use them in soups, succotash, or as a hearty side dish.
Cooked Acorn Squash
For a naturally sweet and fibrous option, acorn squash is an excellent choice. One cup of cooked acorn squash contains around 9 grams of fiber. It's also high in vitamin C and B vitamins. Roasting acorn squash is a simple and delicious way to prepare it. Just cut it in half, scoop out the seeds, and bake with a little seasoning until tender.
Canned Pumpkin
Not just for holidays, canned pumpkin (not pumpkin pie filling) is a fiber-dense and nutrient-rich vegetable. A cup of canned pumpkin offers about 7.1 grams of fiber. It is also exceptionally high in vitamin A. Pumpkin puree can be added to smoothies, curries, or baked goods to add fiber and moisture.
Cooked Brussels Sprouts
These mini cabbages are a fantastic source of fiber, providing approximately 6.4 grams per cooked cup. Brussels sprouts are also rich in vitamin C and K. Roasting them with a little olive oil and seasoning brings out a delicious, nutty flavor that even skeptics will enjoy.

Why Fiber is Crucial for Your Health
Including high-fiber vegetables in your diet offers an array of proven health benefits that go far beyond basic digestion. Here are some of the key reasons to prioritize fiber-rich foods:
- Digestive Health: Fiber promotes regular bowel movements and prevents constipation by adding bulk to your stool. It acts like a broom, keeping your digestive system running smoothly.
- Heart Health: Soluble fiber, found in many vegetables, binds to cholesterol and helps remove it from the body. This can lower your LDL ('bad') cholesterol levels and reduce your risk of heart disease.
- Blood Sugar Control: Fiber, particularly soluble fiber, slows down sugar absorption, which helps to stabilize blood sugar levels. This is especially important for people with diabetes or those looking to prevent type 2 diabetes.
- Weight Management: Fiber-rich foods tend to be more filling and satisfying than low-fiber foods. This can help you feel full for longer, which may prevent overeating and aid in weight control.
- Gut Microbiome Health: Many types of fiber act as a prebiotic, serving as food for the beneficial bacteria in your gut. A diverse and healthy gut microbiome is linked to improved digestion, enhanced immune function, and better long-term health outcomes.
- Reduced Chronic Disease Risk: Research has shown that a high-fiber diet can lower the risk of developing certain chronic conditions, including heart disease, stroke, and some types of cancer, such as colorectal cancer.
How to Increase Your Fiber Intake with Vegetables
Boosting your daily fiber intake doesn't have to be complicated. Here are some simple strategies:
- Don't Discard the Skin: For vegetables like potatoes and sweet potatoes, the skin is packed with fiber. Always opt to eat them with the skin on whenever possible.
- Add it to Anything: Many high-fiber vegetables can be easily integrated into dishes you already make. Toss a handful of green peas into a pasta dish, add cooked artichoke hearts to a salad, or blend canned pumpkin into a smoothie.
- Cook for Density: For some vegetables like broccoli, the fiber content per cup is actually higher when cooked than when raw. This is because cooking reduces the volume, concentrating the fiber.
- Use Legumes: Many vegetables in the legume family, like lima beans, green peas, and edamame, are incredibly rich in fiber and versatile in cooking.
- Use Frozen and Canned Veggies: Don't hesitate to use frozen or canned vegetables for convenience. While processing can slightly alter fiber content, the nutritional benefits remain substantial, and they are always better than no vegetables.
For more detailed nutritional information on these and other vegetables, you can consult the official USDA FoodData Central database.
Conclusion
While a cooked artichoke heart is the winner in the contest for what vegetable has the most fiber per cup, the true key to a high-fiber diet lies in variety. Incorporating a range of fiber-rich vegetables like green peas, lima beans, and winter squash will ensure you receive a broad spectrum of nutrients and support a healthy gut microbiome. By intentionally adding these powerhouse foods to your meals, you can effortlessly meet your daily fiber goals and reap the numerous benefits for your digestive and overall health.
