Beef: a force of nature that offers 35 g protein/100g serving.1
Beef is a food that contains “mostly protein.” The protein in beef and other meats is what we call ‘complete’, meaning it contains all the essential amino acids that humans need for health. Plant-based proteins, on the other hand, do not, and only contain “some protein.”2 This makes meat more “efficient” at delivering the protein your body requires. Additionally, research shows that protein can help keep you feeling full longer.
Digestibility (bioavailability) is generally better in animal-based proteins compared to plant-based proteins. Animal-based proteins from foods such as meat, milk and eggs, generally have high digestibility; more than 95%.
Meanwhile, protein digestibility of protein foods such as whole grains, legumes, or pulses tends to be lower, around 80 to 90%. Some plant-based proteins have lower digestibility, in the range of 50 to 80% due to plant cell walls and anti-nutritional factors.
