Egg whites (liquid) vs Quinoa (cooked): which protein is cheaper?

Egg whites (liquid) is 1.5x cheaper per gram of protein ($0.046/g vs $0.068/g), while it also carries more protein per calorie (21.0 g vs 3.7 g per 100 kcal), so it wins on both axes.

Food (per serving)	Price	kcal	Protein	Carbs	Fat

Quinoa (cooked) (100 g)	$0.30	120	4.4 g	21.3 g	1.9 g

A week of protein from each

Hitting a common 100 g/day protein target from egg whites (liquid) alone costs $32.11 a week; from quinoa (cooked) alone, $47.73. That is a gap of $15.62 every week for the same protein. In practice you mix sources: the planner computes the cheapest mix for your exact target and calorie cap, live from the same dataset.

This one is not a trade-off

Egg whites (liquid) is both the cheaper protein ($0.046/g against $0.068/g) and the leaner one (21.0 g protein per 100 kcal against 3.7 g). Most matchups force you to pick a side. This one does not, so quinoa (cooked) has to win on taste, prep time or what else it brings to the meal, because it is not winning on the numbers.

The amount you actually have to eat

Thirty grams of protein means 682 g of quinoa (cooked), against 275 g for egg whites (liquid). That is a real constraint, not a footnote: a price per gram only counts if the serving is one a person will finish. Treat quinoa (cooked) as the base of a meal that other protein is added to, not as the protein itself.

What the calories cost you

Getting 30 g of protein from quinoa (cooked) brings 818 kcal with it. On a 2,000 kcal day, three servings would be most of your budget before anything else goes on the plate. That is fine when you are eating at maintenance or building, and it is the reason this food falls apart on a cut no matter how good the price per gram looks.

One of these is a convenience purchase

Quinoa (cooked) ranks #24 of 25 on cost per gram of protein, near the bottom. It is not a bad food, it is an expensive way to buy protein: $2.05 per 30 g against $1.38 for egg whites (liquid). If it is in your basket for the protein, swap it. If it is there because it travels well or you enjoy it, that is a different and perfectly good reason.
