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.

The Duodenum is actually called "Zwölffingerdarm" in German, which directly translates to 12 finger intestine

[@frankmedrisch7451]

Plant proteins dont lack aminoacids, they are relatively low in certain aminoácids. The thing is, grains are low in one type and legumes are low in other, so eating a variety of plants during the day provides all the aminoácids you need. Most plant protein powders also are optimized for this, formulated as a mixture of different plant proteins for a complete aminoácid profile.

[@PSA78]

It might require a bit more as well, I believe they find it to be around 20-30%.

[@DeathGray331]

Bro the thing is you need more volume of plants to get to your protein requirements using plants(and thus money) than using whey protein(yes "good" plant based protein is more expensive) or eating meat, i mean dont get me wrong i use them for my cutting but you get the point, more money and volume need to be used, and not speaking about flavor.

[@nathanclaspell6003]

Why accept an inferior form of protein? Meat has always been a human staple for a reason, and that reason is that it's the best and most bioavailable form of nutrition for our species. It's a bonus that it tastes delicious.

[@dylanberg1188]

Plant protein powder sure, but plants have massive limiting factors when it comes to amino acid profile and availability. You would need to be very particular about your dietary mix and the amounts of individual foods to make are you’re getting even minimum amounts of the protein you really need. It’s infinitely more efficient and easier for the average person to just eat meat.

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.

[@PaulF-yr6dq]

True, but it's ok to eat carbs and fiber. Sure, you could live off just protein and fat but it's realistically much less convenient. Not to mention vegetables of course.

🙋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.
