Plant-based protein sources are often less bioavailable and lower in essential amino acids like leucine and branched-chain amino acids compared to animal sources.

“now most people aren't thinking about how much Lucine is in a meal but we know that Lucine is important for certain aspects of muscle metabolism it's um present in certain proteins and not others you're going to find less of it in a vegetable typically than you would in a piece of chicken and and so on”

“And, in the majority of the literature, when you compare animal versus plant proteins head-to-head, you see greater muscle protein synthesis.”

“gram for gram, as a group, animal proteins are higher quality. They're more anabolic. They have a higher proportion of essential amino acids. They have a higher amount and proportion of the most anabolic-driving amino acids, the branched-chain amino acids, leucine specifically. And, in the majority of the literature, when you compare animal versus plant proteins head-to-head, you see greater muscle protein synthesis.”

“So gram for gram, as a group, animal proteins are higher quality. They're more anabolic. They have a higher proportion of essential amino acids. They have a higher amount and proportion of the most anabolic-driving amino acids, the branched-chain amino acids, leucine specifically.”

“so if we're talking about muscle growth muscle maintenance muscle repair stimulating muscle protein synthesis getting your protein from meat is far superior to plant Foods”

“however, it's probably going to require more planning on your port and just a little bit more attention to detail because uh because of the the factors of limiting amino acids low leucine content those sorts of things”

“the first is what is the digestibility of the protein so here we make a big contrast between plant protein and animal protein this is where animal protein has an enormous advantage over plant protein in that it is far more digestible”

“But we're beginning to see on, when we look at diets, the people who consume higher-quality proteins or sufficient lower quality proteins, which I'm sure we'll get to, it's really about the leucine that they consume, particularly for their muscle, that's important.”

“And I certainly don't think you need to take leucine as a supplement if you're taking in a high-quality protein source, you know, you're eating meat-based proteins. Which, by the way, aren't just meat, they're also milk and eggs, etc. So, proteins from, I should say, animal-based sources. You're going to be getting quality proteins that are rich in leucine.”

“animal proteins are generally Superior to plant proteins for maximizing muscle protein synthesis due to their higher protein density better digestability and complete essential amino acid profiles particularly their Lucine content”
