Fiber is an essential part of a healthy diet, offering a range of health benefits. Despite this, most people do not eat enough fiber. The average American adult consumes 10-15 grams of fiber per day, while the recommended daily amount is 25-30 grams. Fiber can be found in foods such as fruits, vegetables, legumes, whole grains, nuts, and seeds. It can help with weight control, prevent constipation, and lower blood sugar. In addition, a high-fiber diet can reduce the risk of heart disease, cancer, stroke, and type 2 diabetes. To increase fiber intake, one can start their day with a bowl of high-fiber cereal, add more vegetables, legumes, and fruits to their meals, and choose whole grain bread and brown rice over refined options.

What You'll Learn
Recommended daily fibre intake
The recommended daily fibre intake varies depending on age and gender. The USDA recommends a daily fibre intake of 25 grams for women and 38 grams for men under the age of 50. For those over 50, the recommended intake is 21 grams for women and 30 grams for men. However, these values may differ in other parts of the world. In general, adults are advised to consume 25 to 30 grams of fibre per day, with about a quarter of this, i.e., 6 to 8 grams, coming from soluble fibre.
The American Heart Association Eating Plan also suggests a daily fibre intake of 25 to 30 grams, which should ideally come from food sources rather than supplements. This is supported by studies showing that those who consume higher amounts of fibre from vegetables, fruits, and whole grains have a decreased risk of dying from heart disease, stroke, type 2 diabetes, and colon cancer.
To increase your fibre intake, you can incorporate various strategies into your diet. Start your day with a bowl of high-fibre cereal, add vegetables, dried beans, and peas to your soups, and include nuts, seeds, and fruits with your yogurt. Make vegetarian dishes like chilli loaded with beans and vegetables. Enhance your salads with berries, nuts, and seeds. Snack on vegetables like cauliflower, broccoli, carrots, or green beans with healthy dips like hummus. Opt for more whole, natural foods and fewer processed foods.
It is also important to note that while increasing your fibre intake, you should do so gradually to allow your gastrointestinal tract to adjust. Additionally, it is generally better to obtain fibre from whole foods rather than supplements, as whole foods provide different types of fibre, vitamins, minerals, and other beneficial nutrients.

Health benefits of fibre
Fibre is a material from plant cells that cannot be broken down by enzymes in the human digestive tract. There are two main types of fibre: water-soluble and water-insoluble. Each has different properties and characteristics.
Water-soluble fibres absorb water during digestion, increasing stool bulk and possibly lowering blood cholesterol levels. Soluble fibre can be found in fruits (apples, oranges, grapefruit), vegetables, legumes (dry beans, lentils, peas), barley, oats and
Water-insoluble fibres remain unchanged during digestion. They promote the normal movement of intestinal contents. Insoluble fibre can be found in fruits with edible peel or seeds, vegetables, whole grain products (whole-wheat bread, pasta, crackers), bulgur wheat, stone-ground cornmeal, cereals, bran, rolled oats, buckwheat and brown rice.
The recommended daily fibre intake for adults up to 50 years old is 25 grams for women and 38 grams for men. Women and men over 50 should aim for 21 and 30 grams, respectively. However, the average fibre intake among adults in the United States is only about 10 to 15 grams per day.
A diet rich in fibre has numerous health benefits, including:
- Improved digestion and reduced risk of constipation
- Lower cholesterol levels, reducing the risk of heart disease and atherosclerosis
- Regulated blood sugar levels, reducing spikes after high-carb meals
- Weight control by helping you feel full for longer, reducing overeating tendencies
- Reduced risk of chronic diseases, including type 2 diabetes, colon cancer, and stroke

High-fibre foods
Fibre is a nutrient that is a type of carbohydrate that comes from plants. It is essential for digestion and overall health, and it can be found in many high-fibre foods.
The recommended daily amount of fibre for adults up to 50 years old is 25 grams for women and 38 grams for men. Women and men over 50 should aim for 21 and 30 grams, respectively. Most adults, however, consume about 10 to 15 grams of fibre per day, which is less than half of the recommended amount.
- Fruits: pears, strawberries, apples, avocados, oranges, grapefruit, and berries.
- Vegetables: broccoli, carrots, beets, artichokes, and cruciferous vegetables.
- Legumes: lentils, chickpeas, peas, and beans (kidney, dried, and black beans).
- Whole grains: whole-wheat bread, pasta, crackers, brown rice, bulgur wheat, cornmeal, and bran.
- Nuts and seeds: almonds, pistachios, hazelnuts, chia seeds, and flax seeds.
Incorporating these high-fibre foods into your diet can be easy. For example, you can start your day with a bowl of oatmeal topped with berries and nuts or add lentils, chickpeas, or beans to your soups and salads. Using whole-wheat flour in your cooking and baking, choosing whole grain bread, and snacking on raw vegetables with hummus or salsa are also simple ways to increase your fibre intake.

How to increase fibre intake
Fibre is an essential part of a healthy diet, offering benefits such as weight control and reduced risk of heart disease, stroke, type 2 diabetes, and certain cancers. The recommended daily fibre intake for adults is 25 to 30 grams, but most people consume less than half of that.
Incorporate High-Fibre Foods at Every Meal
Including a high-fibre food at every meal is a simple way to increase your fibre intake. Start your day with a bowl of high-fibre cereal or oatmeal topped with berries and seeds. For lunch, opt for a salad or a sandwich on 100% whole grain bread. At dinner, add beans and vegetables to your dishes and experiment with different types of whole grains.
Snack Smart
Choose snacks that are high in fibre, such as raw vegetables with bean dip, fruit with nut butter, dried fruit, nuts, whole grain crackers, or popcorn. These options will help you increase your fibre intake while also providing essential nutrients.
Focus on Whole Grains
Prioritize whole grains over refined grains. When purchasing bread, look for "whole" as the first ingredient on the label and choose options with the highest fibre content per slice. Include at least one serving of whole grains in every meal. Try brown rice, whole wheat pasta, bulgur wheat, or whole grain crackers.
Add Extras
Boost the fibre content of your meals by adding extras like beans, lentils, or vegetables. Toss some berries, nuts, or seeds into your salad. Sprinkle oat bran or wheat germ on your cereal, soup, or yogurt. Use whole wheat flour in your cooking and baking whenever possible.
Eat More Whole Foods
Instead of relying on supplements, focus on getting fibre from whole foods. Whole foods provide different types of fibre, vitamins, minerals, and beneficial nutrients that work together to support your health.
Remember to increase your fibre intake gradually to give your body time to adjust and always ensure you are staying hydrated.

Fibre and weight control
Fibre is often overlooked as a nutrient, but it can be key to achieving good weight-loss results. Fibre is a carbohydrate that the gut cannot digest. It is classified as either soluble or insoluble, depending on whether it dissolves in water or not. Soluble fibres increase stool bulk and may decrease blood cholesterol levels, while insoluble fibres promote the normal movement of intestinal contents.
There is evidence that a high-fibre diet can help with weight control. Fibre can suppress your appetite, making you feel full for longer after a meal or snack. The more viscous the fibre, the better it is at reducing appetite. Viscous soluble fibres such as pectins, beta-glucans, psyllium, glucomannan, and guar gum thicken in water, forming a gel-like substance in your gut. This slows the emptying of your stomach, increasing digestion and absorption times, and ultimately reducing your appetite.
A study published in the Annals of Internal Medicine found that eating 30 grams of fibre each day helped participants lose weight, lower their blood pressure, and improve their body's response to insulin. Another study found that adults who ate several servings of whole grains per day were less likely to have gained weight than those who rarely ate whole grains.
To increase your fibre intake, you can start your day with a bowl of high-fibre cereal or oatmeal with berries, add vegetables, dried beans, and peas to soups, and sprinkle nuts, seeds, and fruit over yoghurt. Whole foods are a better source of fibre than supplements, as they provide different types of fibre, vitamins, and minerals.
