For a number of years, prioritizing protein at breakfast has been an overarching goal – perhaps at the expense of dietary fibre.
Don’t get me wrong – including this vital macronutrient in the morning meal has muscle health and blood sugar benefits, among others.
However, most Canadians consume only about half of their daily recommended fibre intake. And breakfast is an easy meal to start bridging that gap.

Doing so has big payoffs. Adding fibre can lead to improved digestion, steadier energy and better metabolic health.
Here are five evidence-based health advantages of eating more fibre at breakfast, how much to aim for, plus tasty ways to add it to your meal.
A small morning habit with important benefits
Including fibre at breakfast, especially soluble viscous (sticky) fibre found in oats, barley, psyllium, chickpeas, lentils, sweet potatoes, apples, avocados, berries, citrus fruit and chia seeds can help improve satiety and appetite control.
That’s because viscous fibre absorbs water and swells in the stomach, activating stretch receptors that send satiety signals to the brain.
Viscous fibre also slows the rate at which food empties from the stomach into the small intestine. As a result, you stay feeling full longer, helping to quell mid-morning hunger and cravings.
In addition, studies suggest that regularly eating a fibre-rich breakfast can improve insulin sensitivity and blood sugar control, especially in people with insulin resistance, prediabetes and Type 2 diabetes.

The delayed movement of food into the intestine slows glucose absorption into the bloodstream, leading to smaller post-breakfast glucose and insulin spikes.
Soluble viscous fibre can also help lower LDL (bad) cholesterol.
These sticky fibres bind to cholesterol-rich bile acids in the gut, causing them to be excreted. The liver is then forced to pull LDL cholesterol out of the bloodstream to make more bile acids, compounds needed for fat digestion.
Regular breakfast fibre consumption also promotes gut health. It can improve regularity and reduce constipation. It also benefits the gut microbiome.
Prebiotic fibres, found in foods such as whole rye bread, barley, black beans, oats, apples, pears, berries and asparagus, feed beneficial gut bacteria in the large intestine.
In the process, short-chain fatty acids are produced, metabolites that fuel colon cells, reduce inflammation, improve glucose metabolism and increase satiety hormones.
There’s more. Research has consistently shown that fibre at breakfast is a driver of an overall healthier diet and the consumption of nutrient-rich foods across the day.
How much fibre?
The Canadian and U.S. Dietary Reference Intakes (DRIs) for fibre, set in 2005 and based largely on evidence to reduce the risk of coronary heart disease, advise adults ages 19 to 50 to consume 25 g (women) and 38 g (men) each day. Daily fibre recommendations for older women and men are 21 g and 30 g, respectively.
Since 2005, however, strong evidence has accumulated showing greater health benefits from higher fibre intakes, including a lower risk of cardiovascular disease, Type 2 diabetes, colorectal cancer and premature death.
Current data support a daily fibre intake of 30 g to 40 g to reduce chronic disease and early mortality risk.

The Joint U.S.-Canada Dietary Reference Intakes Working Group is actively reviewing and updating the DRIs for energy and macronutrients, including fibre. This review began in 2021 and will occur over several years.
In the meantime, the World Health Organization released updated guidelines for carbohydrates in 2023, recommending that adults consume a minimum of 25 g of fibre each day.
Fibre-packed breakfast ideas
To put a decent dent in your daily fibre target, aim to get at least 10 grams at breakfast. Pair fibre-rich foods with a source of protein to enhance satiety and blood sugar benefits. Here are five suggestions.
Start your day with one cup of oatmeal or overnight oats. Mix in one cup of diced pear and two tablespoons of chopped walnuts; top with a dollop of yogurt and sprinkle of cinnamon (total fibre: 10 g).
Make an omelette or breakfast scramble (with eggs or firm tofu) with one half-cup of black beans, one quarter-cup of chopped bell pepper and a few handfuls of baby spinach. Serve with a sliced orange (total fibre: 12 g).
Try a yogurt parfait layered with one quarter-cup of 100-per-cent bran cereal, one tablespoon of chia seeds and one cup of raspberries or blackberries (total fibre: 19 g).
Enjoy avocado toast made with a slice of 100-per-cent whole grain bread, one quarter-cup of mashed avocado, one quarter-cup of pinto beans, one quarter-cup of pico de gallo and one teaspoon of chia seeds; add a squeeze of lime juice (total fibre: 14 g). For extra protein, add a poached or fried egg.
Make a breakfast green smoothie with milk (your choice), two cups of baby spinach, half-cup each of frozen pineapple and mango chunks, one quarter-cup of dry rolled oats and a tablespoon of chia seeds (total fibre: 11 g).
Don’t stop at breakfast. Think about ways to include fibre at every meal (and snacks) to achieve an optimal daily intake.
