According to Gabrielle Maston, Accredited Practising Dietitian and Spokesperson for the Dietitians Association of Australia, macronutrients are divided into three categories that you’re likely already familiar with – proteins, carbohydrates, and fats. Each of these categories provides the body with the energy it needs in order to keep functioning efficiently.
When it comes to how we consume macronutrients, the importance lies in the composition of your intake. For instance, Gabrielle recommends that 45–65 percent of our energy intake should come from wholefood and wholegrain carbs, while proteins and fats should account for 15–25 percent and 20–35 percent of your total, respectively.
These guidelines are based on the general Australian population, and your individual needs may vary. “If someone is young, male, and active they need more of things like carbohydrates and protein compared to an elderly person who’s a smaller female,” Gabrielle warns. Your needs can also change due to illness or pregnancy, or because of dietary restrictions due to allergy or personal choices. If you’re concerned about your dietary intake, Gabrielle advises that a blood test from a GP is the best course of action.
