Tag: Richest protein source

With a protein content ranging from 55-70% of its dry weight, the microalga spirulina is widely considered the richest source of protein in the world. However, the concept of a "richest" source requires a closer look at factors like protein quality and density, as well as the distinction between plant-based and animal-based options.

According to the USDA, a 3-ounce serving of cooked, skinless chicken breast provides approximately 27 grams of high-quality protein, making it one of the most efficient options. But what meat is the richest in protein across all categories, including game and seafood? The answer reveals a surprisingly diverse range of nutrient-dense choices.

Soybeans can contain between 36 and 56% protein by dry weight, making them a formidable contender for the richest source of plant protein. While many plant foods offer a protein boost, identifying the single richest source requires a closer look at both concentration and nutritional quality.
