Overview

Quinoa is a pseudocereal that has been consumed for thousands of years and is increasingly recognised as a highly nutritious, plant-based food. Unlike most grains, quinoa is a complete protein, containing all nine essential amino acids.

It has been studied for its role in supporting metabolic health, cardiovascular function, and glycaemic control. Its combination of protein, fibre, and micronutrients makes it a valuable component of a balanced, longevity-focused diet.

Nutrient Profile

Quinoa is rich in:

- Complete protein (all essential amino acids) - Fibre — supporting gut health and glycaemic control - Magnesium — supporting metabolic and cardiovascular health - Iron — supporting oxygen transport and energy levels - Folate — important for cell function and DNA synthesis - Polyphenols — contributing to antioxidant activity

This combination makes quinoa both nutritionally dense and metabolically supportive.

Why We Include It

Quinoa is included for its role in supporting metabolic health, protein intake, and sustained energy.

Its combination of protein and fibre helps regulate blood glucose levels, making it beneficial for metabolic health. As a complete plant protein, it also supports muscle maintenance and overall nutritional balance.

Quinoa also contributes to dietary iron intake, which is particularly relevant for women, alongside providing magnesium and other key micronutrients.
