Since 1993, the preferred way of determining protein quality has been the protein digestibility-corrected amino acid score (PDCAAS). However, the two protein quality scoring systems that hold the most value today are PDCAAS and DIAAS. Some of these have included the biological value (BV) and nitrogen balance. There have been many different systems that try to ascertain the quality of protein over the years. It is important to be aware of how the protein bioavailability of foods may affect total protein intake.įor instance, choosing only low-quality protein sources could potentially result in a protein deficiency. Protein and Amino Acid Bioavailability From Animal and Plant Foods Among plant foods, soy-based foods are the most concentrated of these protein sources. Key Point: Fish and meat offer the highest amounts of protein overall. However, the total amount of protein and amino acids in food doesn’t tell the whole story.Īs previously mentioned, the bioavailability of these amino acids is crucial, and the amount we can digest differs depending on the food.

Fish, shellfish, and other types of seafood.Dairy foods such as cheese, milk, yogurt, and whey.Some of the most popular sources of animal protein include What Is Animal Protein?Īnimal protein refers to the dietary protein we can get from animal-based foods. This article takes a balanced look at what the data shows about the respective protein quality of animal and plant foods. However, how do they compare with traditional animal proteins? With the promotion of legumes such as lentils, beans, and the wide range of vegan “meat” products, there are many different plant proteins out there. In recent times, we can hear the words “plant protein” much easier than we could in the past. Facebook 2.3k Tweet Pin 50 Email 10 Print
