Protein head-to-heads · July 2026
Wheat flour (all-purpose) vs Quinoa (cooked): which protein is cheaper?
USDA macros joined to current US grocery prices, reduced to the two numbers that decide it: dollars per gram of protein, and protein per calorie.
Wheat flour (all-purpose) is 5.9x cheaper per gram of protein ($0.012/g vs $0.068/g), while Quinoa (cooked) is the leaner choice at 3.7 g protein per 100 kcal against 2.8 g. Budget favours one, a calorie cap favours the other.
| Food | $/g protein | 30 g protein costs | You need | kcal that come with it | Protein/100 kcal |
|---|---|---|---|---|---|
| Wheat flour (all-purpose) | $0.012 | $0.35 | 291 g | 1060 kcal | 2.8 g |
| Quinoa (cooked) | $0.068 | $2.05 | 682 g | 818 kcal | 3.7 g |
Full macros, per serving
| Food (per serving) | Price | kcal | Protein | Carbs | Fat |
|---|---|---|---|---|---|
| Wheat flour (all-purpose) (100 g) | $0.12 | 364 | 10.3 g | 76.3 g | 1 g |
| 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 wheat flour (all-purpose) alone costs $8.16 a week; from quinoa (cooked) alone, $47.73. That is a gap of $39.57 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.
Budget says one, calories say the other
Wheat flour (all-purpose) costs $0.012 per gram of protein against $0.068, so it saves $39.57 a week at a 100 g/day target. Quinoa (cooked) answers a different question: 3.7 g of protein per 100 kcal against 2.8 g, which is what matters once calories, not dollars, are the thing you run out of first.
The amount you actually have to eat
Thirty grams of protein means 682 g of quinoa (cooked), against 291 g for wheat flour (all-purpose). 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 wheat flour (all-purpose) brings 1060 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.
The gap here is 5.9x, which is unusual
Most matchups in this dataset land inside 2x. Quinoa (cooked) costing 5.9x what wheat flour (all-purpose) does for the same gram of protein means you are buying something other than protein: processing, shelf stability, convenience or flavour. Worth paying for sometimes, but name it, because at a 100 g/day target that gap is $39.57 a week and $2057.74 a year.
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 $0.35 for wheat flour (all-purpose). 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.
