What you need to know about fibre

Updated: Nov 25, 2022

Read here to learn what fibre is, why it's important, and how to get more in through diet.

Key Messages

  1. Most Canadians don't meet half their daily fibre requirements.

  2. There are two types of fibre - soluble and insoluble.

  3. Increase your daily fibre to improve digestion, keep you regular, manage weight, lower cholesterol, and reduce risk of chronic disease.

  4. Add fibre to your diet by increasing daily vegetables and fruit, whole grains, legumes, nuts and seeds.

Fibre is found in so many foods, but most Canadians do not get enough from diet.

With busy lifestyles and convenience culture, people are leaning more and more towards packaged and processed foods, fast food, restaurant food delivery, etc.

The fact that about half of Canadians do not meet their daily fibre requirements goes hand in hand with the fact that most Canadians do not get the recommended daily amount of vegetables and fruit.

But fibre is pretty ubiquitous, being found in many healthy convenience foods (Ex. trail mix, vegetables and fruits).

There are numerous ways to boost your fibre through diet, without having to make a lifestyle or dietary overhaul.

So let's talk about what fibre is, why it's important, and how to increase fibre in your diet.

Why is fibre important?

You have probably at least heard that fibre is important for health. Well, it is!

Fibre has a ton of benefits, including:

  • Keeping you regular

  • Improving digestion

  • Lowering your cholesterol

  • Controlling blood sugar

  • Controlling body weight

  • Lowering risk of heart disease

  • Lowering risk of some cancers such as colon cancer

What is dietary fibre

Dietary fibre is non-digestible carbohydrate found in plant foods like vegetables, fruit, legumes, whole grain cereals, nuts, and seeds.

It can be grouped in two main types – Insoluble and soluble fibre, each having separate and complementary health benefits. So it's good to get both.

Soluble fibre helps control blood sugars and lowers cholesterol. It is found is some fruits and vegetables, and grains like oats and chia seeds (it’s why your chia puddings and overnight oats absorb all the water!). It is also found in legumes like beans and lentils.

Insoluble fibre helps keep you regular. It is found in vegetables and fruit, whole grains, and wheat bran.

Is all fibre created equal?

No, but all the many wonderful fibre types have both unique, and complementary effects on health.

Like I mentioned above, you have two main groups of fibre – Insoluble and soluble. And each group many different fibre types within each group, with many different positive effects. For example beta-glucan is one type of soluble fibre found in oats that has been shown to lower cholesterol and improve heart health.

Should you take fibre supplements?

Fibre supplements often contain only one or two types of fibre - So you may be missing out on the many benefits of all the different fibres found in different foods.

Whole foods on the other hand, contain a variety of different fibres!

If you are unable to get fibre from diet, supplements can help. Supplements typically use inexpensive forms of fibre, sell them at a high price, and use fibre in their product health or nutrient claim. Unfortunately sometimes these claims can be misleading in the context of the person and their entire diet and lifestyle.

The best option is a varied diet of whole grains, vegetables, fruits, legumes, nuts and seeds.

Save your money on pricey supplements and instead buy more vegetables, fruits, legumes, nuts, seeds, and whole grains!

Supplements can help you meet daily goals - But the best option is a varied diet of whole grains, vegetables, fruits, legumes, nuts and seeds.

Use these foods to increase your fibre!!

By adding the following foods to your diet:

  • Vegetables

  • Fruit

  • Whole Grains

  • Legumes (Ex. Beans, peas, and lentils)

  • Nuts and seeds

By following one or more of these practical strategies:

  • Eat a balanced and varied diet of whole foods, and include other healthy lifestyle options like exercise and sleep.

  • Eat more vegetables (and fruit) as snacks.

  • Choose whole grain products over simple carbs.

  • Include high fibre foods in your baking, such as bananas or applesauce instead of sugar, or adding in oats, flaxseed, bran flakes, and other whole grains. Banana bread and chocolate zucchini bread are great options!

  • Choose some meals to be vegetarian, with a focus on vegetables and/or legumes.

  • Compare nutrition labels, choose the one with more fibre per serving.

  • Remember to aim for 25 to 38 grams of fibre per day (depending on age/gender).

  • Make sure that when increasing fibre in your diet, you drink more water (at least 2-3 litres per day). – This will help prevent constipation.

  • Consider dietary supplementation if the above are not possible.
