The Percentage of Calories From Protein in Plant Foods

QUESTION: “I see many graphics and lists on the internet such as this one here, that list the amount of protein in plants and some of them seem really high. Are they accurate?

I have seen the same lists and some of the numbers are accurate and some aren’t. To clarify the issues, I created the following charts, which are based on the latest values from USDA Standard Reference Release 26, which is the most up-to-date values. I have listed the specific NDB# I used for the calculation as different forms (raw, cooked, frozen) of the food and different varieties (russet, yukon gold, red, white) will come up with slightly different numbers. In addition, check out my articles on protein below.
