If acai has the protein profile of an egg, why does the label state 0 grams of protein?

Protein quality is usually ranked by comparing it to the amino acid profile of an egg, which is regarded as ideal. Protein is found in animal and plant sources. Animal proteins such as meat, milk, and cheese are more similar to an egg’s protein profile and are ranked higher in quality than protein from plant sources. This ranking is based upon the profile of the essential amino acids it possesses.

The açai berry is unique because it contains all the essential amino acids. Therefore, the protein found in açai is considered a high-quality protein, even though it is from a plant.

Protein quality, however, does not directly refer to the amount of protein. While açai is a complete protein—meaning it has all essential amino acids—the actual amount of protein per serving is less than one gram per ounce; therefore, it states “0 grams” of protein on the product’s nutritional facts panel. Four ounces of MonaVie juice, however, provide 1 gram of protein.
