This study aims to comparatively analyze the protein content of three widely consumed plant-based foods—African breadfruit (Treculia africana), brown beans (Phaseolus vulgaris), and soybeans (Glycine max). While all three are significant sources of dietary protein, their exact protein contents and nutritional profiles remain subjects of debate, particularly concerning breadfruit, which has been inconsistently categorized as either protein-rich or carbohydrate-dominant. The objective of this research was to determine and compare the protein content of these foods using standard laboratory methods. By providing a quantitative analysis, this study seeks to clarify existing ambiguities regarding the nutritional value of African breadfruit, a commonly consumed but under-explored tropical fruit. Protein contents were determined through Kjeldahl nitrogen analysis, and results were analyzed and compared across the three foods. The findings reveal significant differences in protein concentration, with soybeans demonstrating the highest protein content, followed by brown beans, and African breadfruit. This research is particularly relevant to diabetic patients, vegetarians, dietitians, and the general public seeking affordable and nutritious alternatives to animal-based protein. The study contributes to the growing body of knowledge on plant-based nutrition and offers insights into the potential dietary benefits of these food sources, emphasizing the importance of accurate nutritional labeling in food security and public health.
