Fat, protein, and carbs—the big three macronutrients have all had their turn being vilified throughout diet culture (from problematic phrases such as “all fats are unhealthy” and “watch your carbs” to misguided rhetoric about protein being the only way to build muscle). Yet this powerful triad of nutrients, in tandem with essential vitamins and minerals, is what our body relies on to thrive.
The ABCs of macros and micros
So, what exactly are these all-important nutrients?
Macros
In simple terms, macronutrients refer to the nutrients our body relies on for energy, which we require in large amounts (hence the term macro) to make up our total caloric intake. The big three macros: protein, carbohydrates, and fat.
Micros
On the other hand, micronutrients are the nutrients our body requires in trace amounts. These come in the form of vitamins and minerals. And while they don’t affect our diet from a caloric standpoint, they’re still essential for our health and well-being—from B-complex vitamins’ role in energy production and digestion to iron’s impact on cognitive function and immune support.
The big three players
While protein, carbohydrates, and fat are widely known nutrients, there’s plenty of mixed messaging around them, such as the “correct” daily protein requirement and the “healthiest” form of carbs. Here, we dig into the fundamentals of each and explain why it’s the balance of all three macros that deserves our true attention.
Protein
This powerhouse nutrient is something of a workhorse. Made up of amino acids (the “building blocks” of protein), it helps build and repair our muscles, bones, skin, and other tissues. It also plays a role in hormone and enzyme production.
Fat
Despite a once-shaky reputation, fat (especially the heart-healthy unsaturated variety) is integral to a healthy, balanced diet. One of its main superpowers: helping the body absorb fat-soluble vitamins A, D, E, and K. Fat also protects our organs, aids in cell growth, promotes better cognitive function, and provides us with sustained energy.
Carbohydrates
Carbs are broken down into simple sugars (called monosaccharides) that enter the bloodstream and are used by all cells in the body for energy. When we’re consuming carbs in their whole food form (think fruits, vegetables, whole grains, and legumes), they also provide us with fibre and prebiotics, which are necessary for efficient digestion.
A well-rounded diet
While no nutrient alone holds the key to overall well-being, the secret is to consume a balance of macros and micros in their minimally processed form.
Ultimately, our diets should be filled with foods that bring us joy—whether it’s a veggie-packed stir-fry or our favourite homemade dessert. That, as it turns out, is the closest thing to a winning recipe.
