What is fibre?
Fibre, also called dietary fibre, is the part of plant foods that the body cannot digest. Fibre is found in vegetables and fruit, whole grain foods, nuts and seeds, and dried beans, peas and lentils. Fibre can be either insoluble or soluble. Most foods have a combination of both.
Canada’s food guide recommends eating whole grain foods like oats, quinoa and brown rice. Whole grains include all parts of the grain and have more fibre than refined grains. They also have more vitamins and minerals.
Why is fibre important?
Eating high-fibre foods can lower your risk of type 2 diabetes, heart disease, and colon cancer.
Insoluble fibre can help keep your gut healthy and prevent constipation.
Soluble fibre can help:
- Lower your blood cholesterol level
- Control your blood sugar levels
- Keep you feeling full longer
How much fibre do I need?
Depending on your age and sex, aim for the following amount of fibre each day:
|1 to 3||19 g||19 g|
|4 to 8||25 g||25 g|
|9 to 13||31 g||26 g|
|14 to18||38 g||26 g|
|19 to 50||38 g||25 g|
|51 to 70+||30 g||21 g|
|Pregnancy (any age)||/||28 g|
|Breast feeding (any age)||/||29 g|
g = gram
People with intestinal diseases may not be able to eat large amounts of fibre, or may need to limit certain food sources of fibre. Speak with your health care provider or registered dietitian to find out how much fibre is right for you.
How can I increase the amount of fibre I eat?
Add fibre to your diet slowly to limit gas, cramping and discomfort. As you increase the amount of fibre in your diet, drink more fluids such as water to help keep your bowel movements soft. Here are some tips to eat more high fibre foods every day:
- Include a vegetable or fruit at every meal and snack.
- Start the day with a whole grain breakfast cereal such as oatmeal or whole grain bread
- Add cooked brown or wild rice, quinoa, pot barley or bulgur to your soup, salad or stir fry
- Add cooked lentils or beans to your soup, casserole, pasta sauce or salad
- Add dried fruits, nuts or seeds to yogurt, muffins, or salads, or eat them on their own
If you find it hard to eat enough fibre from food, talk to your health care provider or registered dietitian about a fibre supplement.
Tips for Reading Food Labels
Check the nutrition facts table on packaged foods for the amount of fibre in a serving. Look for labels that say “high” or “very high” source of fibre, which means the food has at least 4 to 6 grams of fibre per serving.
To identify whole grain foods, check the ingredient list for the words “whole grain” followed by the name of the grain as one of the first ingredients. For example, look for a whole grain flour as a first ingredient in bread. Whole wheat foods, such as 100% whole wheat bread, may not be whole grain but they are still a good source of fibre.
