Protein head-to-heads · July 2026
Cottage cheese (lowfat) vs Split peas (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.
Split peas (cooked) is 1.3x cheaper per gram of protein ($0.022/g vs $0.027/g), while Cottage cheese (lowfat) is the leaner choice at 13.1 g protein per 100 kcal against 7.2 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 |
|---|---|---|---|---|---|

| Split peas (cooked) | $0.022 | $0.65 | 361 g | 419 kcal | 7.2 g |
Full macros, per serving
| Food (per serving) | Price | kcal | Protein | Carbs | Fat |

A week of protein from each
Hitting a common 100 g/day protein target from split peas (cooked) alone costs $15.18 a week; from cottage cheese (lowfat) alone, $19.09. That is a gap of $3.91 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
Split peas (cooked) costs $0.022 per gram of protein against $0.027, so it saves $3.91 a week at a 100 g/day target. Cottage cheese (lowfat) answers a different question: 13.1 g of protein per 100 kcal against 7.2 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 361 g of split peas (cooked), against 273 g for cottage cheese (lowfat). That is a real constraint, not a footnote: a price per gram only counts if the serving is one a person will finish. Treat split peas (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 split peas (cooked) brings 419 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.
