Foods Highest in Protein per 100g (USDA Database)

The Top 20: Protein per 100g

What the Rankings Actually Mean

A per-100g ranking is a useful starting point, but it can be misleading without context. Foods at the top of the list — vital wheat gluten, defatted peanut flour, soy flour — are concentrated or dried products. Their water content has been removed or their fat extracted, which compresses a large amount of protein into a small physical mass. That is great for protein density, but it does not reflect how these ingredients behave in a meal. Parmesan is a good illustration. At 41.6g of protein per 100g, it outranks chicken breast by a wide margin. But a typical serving of grated parmesan over pasta is closer to 10–15 grams, which delivers 4–6g of protein. A 150g chicken breast roasted for dinner provides roughly 46g. The per-100g number is real, but serving size context is what determines the actual contribution to your daily intake. Pork rinds tell a similar story. At 61.3g per 100g, they rank second overall. A standard 28g snack bag delivers about 17g of protein — reasonable, though the sodium content (typically 500–700mg per serving) is worth noting depending on your dietary goals. This is not a flaw in the ranking method; it is just the nature of the metric. Per-100g comparisons are most useful when you are evaluating foods you consume in roughly similar volumes — for example, choosing between chicken breast and turkey breast for a weekly meal plan.

Best Protein Sources by Practical Serving

Plant-Based Protein: Where Do They Rank?

Plant proteins occupy a wide range in the per-100g ranking, and the spread is larger than most people expect. At the top, dry roasted soybeans hit 43.3g per 100g — a figure that rivals many cuts of meat. Soy flour and defatted peanut flour both clear 50g, though they function as ingredients rather than standalone foods. Among foods you would eat without processing, dry roasted soybeans are genuinely competitive with animal sources. A 28g serving (roughly a small handful) provides about 12g of protein, which is comparable to two eggs. They are also shelf-stable and require no preparation, which makes them practical as a snack. Edamame — immature soybeans served in the pod — comes in at 11.9g per 100g cooked weight. That is lower than dry roasted because of the added moisture from cooking, but a 155g serving delivers around 18g of protein alongside a useful amount of fiber and folate. Lentils at 9g per 100g (cooked) and chickpeas at 8.9g look modest in a per-100g table. The relevant frame is the serving: a 200g portion of cooked lentils contributes 18g of protein alongside roughly 16g of dietary fiber, a combination that is difficult to match with animal sources at a similar calorie level. Tofu ranks lower than many people expect at 8.1g per 100g. The primary reason is water content — tofu is roughly 85% water by weight. Pressing tofu before cooking removes moisture and raises the effective protein concentration, which is why pressed and extra-firm varieties trend toward the higher end of published values.

How to Use This Data

• Compare foods in similar serving sizes, not just per-100g values — a half cup of cottage cheese and a large egg both contain roughly 6–7g of protein, which the ranked table alone does not make obvious.
• Use high-density specialty sources like soy flour and wheat gluten as ingredients in recipes (protein pancakes, seitan, protein bars) rather than evaluating them as standalone foods.
• When planning weekly meals, anchor your protein around the practical-serving table: canned tuna, cooked chicken breast, and cottage cheese consistently deliver 25–50g per meal-sized portion with minimal preparation.
• For plant-based diets, dry roasted soybeans and lentils are the most cost-effective sources by protein-per-dollar at typical US retail prices. Firm tofu is the most versatile across cooking methods.
• Cross-reference protein data with other nutrients that matter for your goals — sodium in jerky and pork rinds, saturated fat in hard cheeses, and fiber in legumes all affect whether a high-protein food is actually a good fit for a given meal.
