In this week’s Nutrition Diva podcast, I talked about the concept of protein density and why it really matters.
Plant-based sources of protein like legumes or nuts often contain a lot of additional calories in the form or carbohydrates and/or fats. It can be challenging to to increase your protein intake using plant-based sources without taking in more calories than you need. This is where the concept of protein density can help.
We can calculate the protein density of a food by dividing the protein by the calories and multiplying by 100. Foods with a higher protein density provide more protein per calorie. For example, black beans have a protein density score of 6.6, meaning that 100 calories worth of black beans contains 6.6 grams of protein. Edamame, on the other hand, has protein density of around 10. You get 50% more protein from the same number of calories. (Although the calories and protein will change with the serving size, the protein density will always remain the same.)
Here is a table of some common foods and their protein density. You can sort this list by any column by clicking on the column header.

Most diets pay way too much attention to what you eat and not enough to why and how you are eating it. You get detailed instructions about exactly what to eat and what not to eat. And if you follow the instructions, you will almost certainly lose weight.
