There are many different types of beans and legumes, and they all vary nutritionally.
In this article, we examine the most common varieties of legumes and their nutritional values.
For each legume variety, you can see its basic nutritional profile.
Additionally, the three vitamins or minerals that they contain in the most significant amount are listed.

Final Thoughts
This guide covered a broad range of the different available varieties of beans and legumes.
While these foods often have similar nutrient profiles, soybeans and lupin beans tend to offer the most protein (and least carbohydrate).
In contrast, the most significant legume sources of fiber are adzuki beans, kidney beans, and navy beans.
All of these options offer their own unique nutritional profile, and they can all play a part in a nutritious diet.
