High-fibre foods
Fibre is an essential part of a healthy diet, offering a range of health benefits, such as lowering blood sugar, managing constipation, and boosting heart health. High-fibre foods include fruits, vegetables, legumes, nuts, seeds, and whole grains.
Fruits that are rich in fibre include pears, strawberries, avocados, apples, raspberries, bananas, and dried fruits like dates, prunes, and raisins. Vegetables that are good sources of fibre include cruciferous vegetables like broccoli, as well as carrots, beets, and artichokes. Legumes, such as lentils, chickpeas, and kidney beans, are also excellent sources of fibre and provide plant-based protein and various minerals.
Whole grains, such as oats and quinoa, are high in fibre and other essential nutrients. Quinoa, in particular, is a good source of protein, magnesium, folate, vitamin B1, and phosphorus. Nuts and seeds, such as almonds, chia seeds, and flax seeds, are also good sources of fibre and healthy fats.
It is important to note that while increasing fibre intake can have health benefits, it should be done gradually to prevent gas and bloating. Additionally, it is crucial to maintain a balanced diet and consider the number of calories and other nutrients in addition to fibre content when making dietary choices.

Fibre and health
Fibre is important for our overall health, including heart and digestive health. It can help reduce the risk of developing various conditions, such as heart disease, diabetes, diverticular disease, constipation, and colon cancer. It is also important for lowering cholesterol.
There are two main types of fibre: water-soluble and water-insoluble. Soluble fibre absorbs water during digestion, increasing stool bulk and may help lower blood cholesterol levels. Good sources of soluble fibre include fruits such as apples, oranges, and grapefruit, as well as vegetables, legumes (like dry beans, lentils, and peas), barley, oats, and oat bran. Insoluble fibre remains unchanged during digestion and promotes the normal movement of intestinal contents. Whole grains, such as brown rice and whole-wheat flour, are good sources of insoluble fibre.
The recommended daily fibre intake is around 25 to 30 grams, with about one-fourth of that coming from soluble fibre (6 to 8 grams). However, the average adult in the United States consumes only about 15 grams of fibre per day, which is about half of the recommended amount. To increase fibre intake, it is suggested to include at least one serving of whole grain in every meal and choose high-fibre options like whole grain bread and cereals with at least 5 grams of fibre per serving. Additionally, eating more fruits, vegetables, legumes, nuts, and seeds can help meet fibre requirements.
It is important to introduce high-fibre foods gradually to prevent gas and bloating. High-fibre meals should be balanced with other nutrients and calories to ensure a well-rounded diet. A registered dietitian can provide guidance on creating a fibre-rich meal plan that meets individual calorie needs and health goals.

Fibre sources
Fibre is important for overall health, including heart and digestive health, and may reduce the risk of developing various conditions, including heart disease, diabetes, diverticular disease, constipation, and colon cancer. While there is no dietary reference intake for insoluble or soluble fibre, experts recommend a total dietary fibre intake of 25 to 30 grams per day, with about one-fourth (6 to 8 grams per day) coming from soluble fibre. The average American consumes only 15 grams of fibre per day, which is far below the recommended amount.
There are two types of fibre: water-soluble and water-insoluble. Soluble fibre absorbs water during digestion, increasing stool bulk and may decrease blood cholesterol levels. Good sources of soluble fibre include fruits such as apples, oranges, grapefruit, and raspberries, vegetables, legumes such as dry beans, lentils, and peas, barley, oats, and oat bran. Insoluble fibre, on the other hand, remains unchanged during digestion and promotes the normal movement of intestinal contents. Whole grains, such as whole-wheat flour, whole-grain bread, brown rice, and cereals, are good sources of insoluble fibre.
Some high-fibre foods include:
- Fruits: Strawberries, pears, apples, raspberries, bananas, avocado, and dried fruits like raisins.
- Vegetables: Brussels sprouts, potatoes with their skins on, and carrots.
- Legumes: Chickpeas, lentils, split peas, and black beans are excellent sources of fibre and plant-based protein.
- Whole grains: Oats, oatmeal, quinoa, and popcorn are good sources of fibre and can be easily incorporated into meals.
- Nuts and seeds: Almonds, chia seeds, and peanut butter are nutritious and high in fibre.
It is important to note that adding too much fibre too quickly can cause stomach cramping, gas, and bloating. It is recommended to introduce high-fibre foods gradually and increase water intake throughout the day. Additionally, it is crucial to balance the nutrients in your diet, considering not just fibre but also the number of calories and other nutrients per portion.
