Protein head-to-heads · July 2026
Vital wheat gluten vs Whey protein (1 scoop): 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.
Vital wheat gluten is 2.4x cheaper per gram of protein ($0.013/g vs $0.031/g), while it also carries more protein per calorie (20.3 g vs 20.0 g per 100 kcal), so it wins on both axes.
| Food | $/g protein | 30 g protein costs | You need | kcal that come with it | Protein/100 kcal |
|---|---|---|---|---|---|
| Vital wheat gluten | $0.013 | $0.40 | 40 g | 148 kcal | 20.3 g |
| Whey protein (1 scoop) | $0.031 | $0.94 | 38 g | 150 kcal | 20.0 g |
Full macros, per serving
| Food (per serving) | Price | kcal | Protein | Carbs | Fat |
|---|---|---|---|---|---|
| Vital wheat gluten (100 g) | $1.00 | 370 | 75.2 g | 13.8 g | 1.9 g |
| Whey protein (1 scoop) (30 g) | $0.75 | 120 | 24 g | 3 g | 1.5 g |
A week of protein from each
Hitting a common 100 g/day protein target from vital wheat gluten alone costs $9.31 a week; from whey protein (1 scoop) alone, $21.88. That is a gap of $12.57 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.
This one is not a trade-off
Vital wheat gluten is both the cheaper protein ($0.013/g against $0.031/g) and the leaner one (20.3 g protein per 100 kcal against 20.0 g). Most matchups force you to pick a side. This one does not, so whey protein (1 scoop) has to win on taste, prep time or what else it brings to the meal, because it is not winning on the numbers.
