Protein intake plays a crucial role in the formation and maintenance of tissues in the body through several key processes:
1. Amino Acids Supply
Building Blocks: Proteins are composed of amino acids, which are the fundamental building blocks required for tissue growth, repair, and maintenance. When you consume dietary protein, it is broken down into amino acids during digestion.
2. Protein Synthesis
Tissue Formation: The amino acids absorbed from dietary protein are used in protein synthesis, where cells assemble these amino acids into specific proteins needed by the body. These proteins are essential for forming various tissues, including muscle, skin, hair, and organs.
Enzyme Function: Many enzymes, which are proteins themselves, are involved in metabolic processes that facilitate tissue repair and growth.
3. Repair and Maintenance
Tissue Repair: Proteins are vital for repairing damaged tissues. For instance, after an injury or exercise, the body requires proteins to rebuild muscle fibers and heal wounds.
Collagen Production: Collagen is a structural protein that helps maintain the integrity of connective tissues such as skin, ligaments, and tendons.
4. Growth and Development
Cell Growth: Proteins are essential for cell division and growth, particularly important during developmental stages such as childhood, adolescence, and pregnancy.
Hormones and Growth Factors: Many hormones and growth factors, which regulate tissue growth and development, are proteins or peptides (short chains of amino acids).
5. Immune Function
Antibodies: Proteins are crucial for the immune system. Antibodies, which help fight infections, are proteins produced by the immune cells.
6. Transport and Storage
Hemoglobin and Myoglobin: These are proteins that transport oxygen in the blood and muscles, respectively, ensuring that tissues receive the oxygen they need for metabolism and energy production.
7. Structural Proteins
Keratin: Found in hair, nails, and skin, keratin is a tough, fibrous protein that provides strength and protection.
Actin and Myosin: These proteins are involved in muscle contraction and movement, crucial for muscle tissue function.
Summary
Protein intake is fundamental for tissue formation because it provides the necessary amino acids for building, repairing, and maintaining various tissues in the body. Through processes like protein synthesis, repair mechanisms, and the production of structural and functional proteins, dietary proteins ensure the body can grow, heal, and function optimally.
The recommended daily protein intake varies based on several factors, including age, sex, weight, activity level, and health status. Here are general guidelines for protein intake for different groups:
General Recommendations
1. Average Adult:
• Recommended Dietary Allowance (RDA): 0.8 grams of protein per kilogram of body weight per day.
• Example: A person weighing 70 kg (154 lbs) would need about 56 grams of protein per day.
2. Infants and Children:
• Infants (0-6 months): 1.52 grams per kilogram of body weight per day.
• Infants (7-12 months): 1.2 grams per kilogram of body weight per day.
• Children (1-3 years): 1.05 grams per kilogram of body weight per day.
• Children (4-8 years): 0.95 grams per kilogram of body weight per day.
• Children (9-13 years): 0.95 grams per kilogram of body weight per day.
3. Adolescents:
• Boys (14-18 years): 0.85 grams per kilogram of body weight per day.
• Girls (14-18 years): 0.85 grams per kilogram of body weight per day.
4. Adults:
• Men: 0.8 grams per kilogram of body weight per day.
• Women: 0.8 grams per kilogram of body weight per day.
5. Older Adults (65 years and older):
• Recommendations suggest that older adults may benefit from higher protein intake, around 1.0-1.2 grams per kilogram of body weight per day, to help maintain muscle mass and function.
Special Considerations
1. Athletes:
• Endurance Athletes: 1.2-1.4 grams per kilogram of body weight per day.
• Strength/Power Athletes: 1.6-2.0 grams per kilogram of body weight per day.
2. Pregnant and Lactating Women:
• Pregnancy: Additional 25 grams per day above the RDA for non-pregnant women (about 1.1 grams per kilogram of body weight).
• Lactation: Additional 25 grams per day above the RDA for non-lactating women.
3. Patients with Specific Medical Conditions:
• Kidney Disease: Protein intake may need to be limited based on the stage of kidney disease and doctor’s recommendations.
• Liver Disease: Protein needs may vary; consult with a healthcare provider.
• Malnutrition or Severe Illness: Increased protein intake may be necessary, sometimes up to 1.5-2.0 grams per kilogram of body weight per day.
4. Weight Loss and Muscle Gain:
• Individuals aiming to lose weight or gain muscle may benefit from higher protein intakes, often around 1.2-2 grams per kilogram of body weight per day. - Zábava

Hi doctor, kindly mention which whey protein is good in the market ??
Hi Dr. Jacob,
Your channel is very informative. I recently got interested in fitness and started swimming. I have a question. When I go swimming, my legs and arms get tired, and I experience pain. The next day, I do not have the energy to perform well. This situation is demotivating me, and it takes at least two weeks for me to get back to somewhat normal. I think this is a common question from newcomers. How can I overcome this? Could you please guide me on this?
Acquiring more knowledge from you dr and dr pal .health is wwealth worth more than diamond

On behalf of everyone, I request you to recommend the best whey powder for the general public. We are confusing to select whey products.
Nowadays, all the influencers share their products. As a medical expert, you can suggest us ...
Hi doctor what about Herbalife protein
It's fake protein powder
For senior citizens(above 65 years), the recommended protein intake is 1 gm per kg of body weight or 0.1 gm per kg of body weight?
1 gm per kg to 1.4 if veg
@@DrSanthoshJacob15:45 u mentioned for older people it is 0.1 to 0.2 g recommended which is bit confusing. Please clarify.
Hi doctor, also please talk about consuming more than adequate protein. I know the excess aminoacids will convert into carbohydrates and eventually into fat. But does that contribute to any other diseases other than resulting in diseases results in excess glucose in blood?
Ok
Same question me too dr. Normal person neraya protin edutha enna agum nu next plant and meat protin eposide la sollunga.
My wife asked the same question if it will be excreted via kidneys as I guess we cannot store protein as such. Questions about protein.
1. Can we measure the amount of protein or amino acids in our blood.
Explain more on the interpretation of BUN, total protein, Serum Albumin, Amino acids analysis etc. How to co-relate these values to our protein intake or synthesis.
2. I have heard herbivores like goat synthesis protein via the gut microbiome. Can vegetarians also produce protein in the same process? I understand ruminant digestive system is different. Still how much can the colon contribute to it and can we have similar biome suppliment.
3. How long does essential amino acids obtained through the diet stay in the blood stream? 4-6 hours? So how much is the per meal protein requirement. It will be .26g * body weight per mean if it's thrice.
4. Talk more about the biological value of vegetarian foods like Milk(91) and nv like chicken (79) and PDCAAS.

👍👍👍👍
For older adults you have recommended 0.2 gms per kg body weight. I think it must be 1.2 gms per kg. please correct it.
Sir... kindly clear the doubt if we take dry fruits smoothie in empty stomach in morning will it reduce the weight
Drg fruits are a great source of fats. Instead of dry fruits focus on increasing fibre rich foods.
