Which is more filling?

By our estimate, quinoa is more filling per calorie than couscous: 4 versus 3 out of 5.

  • Couscous: Calculation: 1 (base) + 1 (low energy density: 112 kcal/100 g) + 0 (protein: 3.4 g/100 kcal) + 0 (fiber: 1.3 g/100 kcal) + 1 (solid food with 72.6 g of water) = 3.
  • Quinoa: Low energy density; moderate fiber per calorie; high water content.

The 1 to 5 score is our own estimate: it starts at 1 point, adds points for low energy density, for protein and fiber per 100 kcal, and for the water in solid foods, and subtracts points for drinks with calories. It is useful for comparing foods with each other; it is not a measurement in people.

When to choose each one

Couscous

  • If you have nausea or fill up quickly: it carries our “Easy to digest” tag.
