Beef jerky vs Sardines (canned in oil): 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.

Sardines (canned in oil) is 3.0x cheaper per gram of protein ($0.055/g vs $0.166/g), while it also carries more protein per calorie (11.8 g vs 8.1 g per 100 kcal), so it wins on both axes.

A week of protein from each

Hitting a common 100 g/day protein target from sardines (canned in oil) alone costs $38.41 a week; from beef jerky alone, $115.96. That is a gap of $77.55 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

Sardines (canned in oil) is both the cheaper protein ($0.055/g against $0.166/g) and the leaner one (11.8 g protein per 100 kcal against 8.1 g). Most matchups force you to pick a side. This one does not, so beef jerky has to win on taste, prep time or what else it brings to the meal, because it is not winning on the numbers.

One of these is a convenience purchase

Beef jerky ranks #25 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: $4.97 per 30 g against $1.65 for sardines (canned in oil). 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.
