From Mouth to Muscle: How Your Body Absorbs Protein

I'm glad you pointed out where the stomach is because when people hold on to their abdomen they don't know they have a gut issue, they keep blaming their stomach

00:00 Introduction to Protein Digestion and Absorption • Protein digestion and absorption in the gastrointestinal tract. • The importance of understanding the process to control protein intake. • Recommendations for timing and amount of protein intake. 00:49 Oral Digestion • Food is digested mechanically and chemically in the oral cavity. • Examples: chewing, salivation, sublingual medications. • Protein digestion in the oral cavity depends on the type of food. 02:03 Stomach Digestion • The stomach as a site of protein digestion. • Hydrochloric acid and pepsin for denaturation and breakdown of proteins. • Chyme and its role in digestion. 03:56 Pyloric Sphincter and Small Intestine • The pyloric sphincter regulates the entry of food into the small intestine. • The small intestine is divided into three segments: the duodenum, jejunum, and ileum. • The duodenum connects to the bile duct and pancreas. 06:37 The difference between proteins, peptides, and amino acids • The importance of understanding the differences between proteins, peptides, and amino acids. • Amino acids as building blocks of proteins. • Peptides and polypeptides as intermediates in protein digestion. 09:07 Absorption in the small intestine • The small intestine as the main site of absorption. • Length and surface area of ​​the small intestine. • Circular folds of the mucosa to increase the surface area for absorption. 10:10 Amino acid absorption • Microvilli in the intestinal folds increase the surface area for absorption. • The mesentery contains blood vessels that absorb nutrients, including amino acids. • Amino acids move from the intestinal lumen into the cells of the mucosa, where they are broken down into amino acids. 11:34 The Role of the Liver in Amino Acid Control • The liver plays a key role in controlling the intake of amino acids. • More than 50% of ingested amino acids are utilized by the liver, with the remainder released into the systemic circulation. • Amino acids are used to create plasma proteins and other important proteins, as well as for energy. 12:17 How Protein Type Affects the Body • The body has no control over where amino acids are sent. • The liver uses more than 50% of amino acids to create proteins and for energy. • It is important to consume enough protein to achieve nitrogen balance. 13:53 Nitrogen Balance • Nitrogen balance is the difference between nitrogen intake and nitrogen loss. • A positive nitrogen balance promotes muscle growth. • The type of protein is important, but maintaining a positive nitrogen balance is most important. 14:35 Complete vs. Incomplete Proteins • Animal proteins like whey and casein contain all the essential amino acids. • Plant proteins can be incomplete due to the lack of certain amino acids. • It is important to get all the essential amino acids from a variety of sources. 15:32 Protein Digestion Rate • Fast-digesting proteins like whey protein are important for post-workout recovery. • The optimal amount of protein depends on your goals and can range from 1.2 to 2 grams per kilogram of body weight. • It is important to maintain a positive nitrogen balance for 24 hours.

On protein requirements, I’d like to see a deep dive on the difference between the requirement for muscle maintenance versus during a period of active synthesis during a building phase. I rarely see this specific aspect focused on in the usual videos on protein intake.

So it would be more efficient to consume the amino-acids directly -- thus saving the body from breaking ingested protein down?

Amino acids are the very first thing I suggest to newbies when asked how I’ve been able to build muscle. That said it’s important to know that emerging science is suggesting that amino acids can also fuel the growth of cancer.

[@EmmaJohnson-dv9cx]

Great Video! Below are the Keypoints Suammrized using ChatWithPDF: 🧠 - The digestive system plays a crucial role in breaking down protein and absorbing it into the bloodstream for distribution to muscles. 🍽 - Different segments of the digestive tract are primarily responsible for either digestion or absorption of protein. 👅 - Digestion begins in the oral cavity through mechanical and chemical processes such as chewing and enzyme release. 🍗 - Protein-rich foods like chicken or steak undergo mechanical digestion in the mouth before moving to the stomach for further breakdown. 🧪 - The stomach plays a key role in digesting proteins through the action of hydrochloric acid and enzymes like pepsin. 🔁 - The pyloric sphincter regulates the movement of food from the stomach to the small intestine based on food type and amount. 🧬 - The small intestine is the main area for absorption of nutrients, including amino acids derived from digested proteins. 🩸 - Amino acids absorbed in the small intestine are transported to the liver for utilization in various bodily functions, including muscle growth. 💪 - The body dictates where ingested proteins are distributed, emphasizing the importance of consuming enough protein for muscle growth. 🥩 - Animal proteins like whey and casein are complete proteins, while plant proteins may lack certain essential amino acids. 🕰 - While timing of protein ingestion can be important for muscle recovery, overall protein intake throughout the day is more crucial for optimal muscle growth.

[@ArodWinterbornSteed]

By your logic digestion begins at the food preparation stage, and continues as you further break down the food with cutlery, all before you ingest it

[@davidmccrory5604]

You sir are an absolute rock God the way you communicate complex concepts in a easy to understand fun way has the education of body mechanics an absolute delight for me . Perhaps I'm being just a little over the top but thankyou for your contribution to society on the fascinating complex machine that we are . So much respect to you my friend 👍

[@garbodorski]

🙋I got a question! At 12:20 you mention how we can't decide where our amino acids get allocated, e.g. we can't guarantee amino acids from whey go mainly to our muscles and amino acids from collagen mainly go to our skin. Does this go against claims around taking collagen peptides having benefits for skin? Let's just say amino acids do benefit skin in some way: if the body treats amino acids indiscriminately regardless of protein source, then that would mean whey protein should improve our skin just like collagen peptides, right? And when we're talking about muscle building, provided that we are in a positive nitrogen balance, we could theoretically use collagen peptides instead of whey protein powder as a supplement for muscle building purposes as long as we make up for its incomplete amino acid profile with another source of protein that compensates for it, right? Someone correct me if I'm wrong here.
