How it compares with similar foods
Protein per calorie is the measure that matters when the goal is to hit a protein target without overshooting total energy. By protein per 100 calories it ranks 99th out of 109 foods in this reference. Within other foods, the highest are:
| Food | Protein | Calories |
|---|---|---|
| Soy Sauce | 8.1 g | 53 kcal |
| Hummus | 7.8 g | 237 kcal |

How to use these numbers
Percentages of daily value are calculated from the FDA Daily Values used on US nutrition labels, which assume a 2,000 calorie diet; your own targets may be higher or lower. If you want the values for your own body weight and activity level rather than a reference diet, the protein and macro calculator turns a calorie and protein target into numbers you can use.
