Quinoa (cooked) vs Lentils (cooked)

The short answer

Both are plant staples people build a bowl around. Lentils are the protein and fibre heavyweight, with more iron, at fewer calories. Quinoa is lighter and complete in amino acids, cooking fluffy rather than soft. Lentils when you want the most protein and fibre per calorie, quinoa for a lighter grain-like base that still carries protein.

Common questions
Is Quinoa (cooked) or Lentils (cooked) better?

Neither is “better” on its own — it depends what you want from it. The table shows where each is higher; the short answer says when each one fits. Compare on the same basis (per 100 g) and pick for your dish and your goal.

How were these numbers worked out?

Straight from USDA FoodData Central for the generic form of each food, per 100 g. We show the portion view too, but portion sizes differ between foods, so per 100 g is the fair comparison.

Why does one column say “no data”?

Because USDA has no value for that nutrient in that food — so we leave it blank rather than print a 0 that would read as “none”. A real zero from USDA still shows as 0.
