Fiber is a type of carbohydrate that your body cannot digest or absorb. It passes through your digestive system mostly intact, and has various benefits for your health and well-being. Fiber can help you lower your cholesterol, control your blood sugar, prevent constipation, lose weight, and reduce your risk of chronic diseases, such as diabetes, heart disease, and some cancers. However, most people do not get enough fiber in their diet.
The recommended daily intake of fiber is 25 grams for women and 38 grams for men, but the average American only consumes about 15 grams per day. How can you increase your fiber intake and enjoy its benefits? One way is to eat more foods that are rich in fiber, such as fruits, vegetables, grains, legumes, nuts, and seeds.
In this article, we will show you 30 foods that are high in fiber, and how to include them in your diet. We will also answer some common questions about fiber, and give you some tips and tricks to make your high fiber diet more enjoyable and effective. Let’s get started!

How to Include More Fiber in Your Diet
Now that you know some foods that are high in fiber, you may be wondering how to include them in your diet. Here are some tips and tricks to help you increase your fiber intake and enjoy its benefits:
- Start your day with a high-fiber breakfast, such as oatmeal, bran flakes, or whole-wheat toast, and add some fruits, nuts, or seeds for extra fiber and flavor.
- Snack on high-fiber foods, such as fruits, vegetables, nuts, seeds, or popcorn, and avoid low-fiber foods, such as chips, crackers, or candy.
- Choose whole grains over refined grains, such as brown rice, whole-wheat pasta, or quinoa, and avoid white rice, white bread, or white flour.
- Add legumes to your meals, such as beans, lentils, or chickpeas, and use them to replace or reduce your intake of animal products, such as meat, cheese, or eggs.
- Eat more salads, and add some high-fiber ingredients, such as leafy greens, carrots, broccoli, or sunflower seeds, and dress them with some olive oil, vinegar, or lemon juice.
- Drink plenty of water, and avoid drinks that may dehydrate you, such as alcohol, caffeine, or soda. Water can help you digest the fiber and prevent constipation, bloating, or gas.
- Increase your fiber intake gradually, and give your body time to adjust. If you eat too much fiber too fast, you may experience some side effects, such as diarrhea, cramps, or nausea. Start with small amounts of fiber, and increase them slowly, until you reach your daily goal.
Common Questions About Fiber
You may have some questions about fiber, and how it affects your health and well-being. Here are some common questions and answers about fiber, that may help you understand it better:
- How much fiber do I need per day? The recommended daily intake of fiber is 25 grams for women and 38 grams for men, but this may vary depending on your age, weight, activity level, and health condition. You can use a [fiber calculator] to estimate your personal fiber needs, or consult your doctor or dietitian for more guidance.
- What are the types of fiber, and what are their benefits? There are two types of fiber: soluble and insoluble. Soluble fiber dissolves in water and forms a gel-like substance in your intestines. It can help you lower your cholesterol, control your blood sugar, and feed your gut bacteria. Insoluble fiber does not dissolve in water and adds bulk to your stool. It can help you prevent constipation, hemorrhoids, and diverticulitis. Both types of fiber can help you feel full and satisfied, and reduce your calorie intake
- What are the sources of fiber, and how can I identify them? The main sources of fiber are plant-based foods, such as fruits, vegetables, grains, legumes, nuts, and seeds. You can identify them by reading the nutrition label of the food, and looking for the amount of fiber per serving. You can also use a [fiber database] to search for the fiber content of various foods, or use a [fiber tracker] to record and monitor your fiber intake.
- What are the benefits of fiber, and how does it work? The benefits of fiber are numerous, and they include:
- Lowering your cholesterol: Fiber can bind to cholesterol in your intestines, and prevent it from being absorbed into your bloodstream. This can help you lower your total and LDL (bad) cholesterol levels, and reduce your risk of heart disease and stroke.
- Controlling your blood sugar: Fiber can slow down the digestion and absorption of carbohydrates, and prevent spikes and drops in your blood sugar levels. This can help you manage your diabetes, or prevent it from developing.
- Preventing constipation: Fiber can add bulk and moisture to your stool, and make it easier to pass. This can help you prevent constipation, hemorrhoids, and diverticulitis, which are conditions that affect your colon and rectum.
- Losing weight: Fiber can make you feel full and satisfied, and reduce your appetite and calorie intake. This can help you lose weight, or maintain a healthy weight.
- Reducing your risk of chronic diseases: Fiber can modulate your immune system, and protect you from inflammation and oxidative stress, which are the root causes of many chronic diseases, such as diabetes, heart disease, and some cancers.
Fiber works by interacting with your digestive system, your blood, and your gut microbiome, which is the community of beneficial bacteria that live in your intestines. Fiber can:
- Stimulate your digestive muscles, and improve your bowel movements.
- Bind to substances, such as cholesterol, bile acids, toxins, and hormones, and eliminate them from your body.
- Ferment in your colon, and produce short-chain fatty acids, which are beneficial for your gut health, metabolism, and immunity.
- Feed your gut bacteria, and enhance their diversity and function.
- What are the side effects of fiber, and how can I avoid them? Fiber is generally safe and beneficial, but it may cause some side effects, especially if you eat too much of it, or if you are not used to it. Some of the side effects of fiber are:
- Gas, bloating, and cramps: Fiber can produce gas in your intestines, and cause discomfort and pain. This is more common with soluble fiber, and with foods that contain sugars, such as beans, fruits, and dairy products.
- Diarrhea: Fiber can speed up your intestinal transit, and cause loose and watery stools. This is more common with insoluble fiber, and with foods that contain sugar alcohols, such as sugar-free candies, gums, and chocolates.
- Nausea: Fiber can fill up your stomach, and cause nausea and vomiting. This is more common with high-fiber supplements, and with foods that are high in fat, such as nuts, seeds, and avocados.
- Nutrient malabsorption: Fiber can interfere with the absorption of some minerals, such as calcium, iron, zinc, and magnesium, and cause deficiencies. This is more common with phytates, which are compounds found in grains, legumes, nuts, and seeds.
You can avoid or minimize the side effects of fiber by following these tips:
- Increase your fiber intake gradually, and give your body time to adjust. Start with small amounts of fiber, and increase them slowly, until you reach your daily goal.
- Drink plenty of water, and avoid drinks that may dehydrate you, such as alcohol, caffeine, or soda. Water can help you digest the fiber and prevent constipation, bloating, or gas.
- Chew your food well, and eat slowly. This can help you break down the fiber and reduce the amount of air that you swallow, which can cause gas and bloating.
- Balance your fiber intake with other nutrients, and eat a varied and balanced diet. This can help you prevent nutrient malabsorption and deficiencies, and ensure that you get all the vitamins and minerals that you need.
