In this one, the authors report the development and validation of the Essential Amino Acid-9 (EAA-9) score, an innovative, nutrient-based protein quality scoring framework, which allows for personalization of essential amino acid needs based on age or metabolic conditions. 
- Currently, recognition of essential amino acid requirements is embedded within a generalized measure of protein quality known as PDCAAS (Protein Digestibility-Corrected Amino Acid Score).
- Calculating PDCAAS includes the FAO/WHO/UNU amino acid score (AAS), which is based on the limiting amino acid in a food, that is, the single amino acid with the lowest concentration compared to the reference standard.
Here, one year of protein supplementation in comparison to an isocaloric-control supplement appeared to affect neither the muscle protein synthesis rate at basal or postprandial state nor the skeletal muscle metabolomein healthy older Danes.
- The skeletal muscle mass decreases with age and the responsiveness of aging muscles protein synthesis rate to protein intake seems to deteriorate.
- This study investigated the impact of 12 months of protein supplementation with or without physical exercise training on the basal and postprandial muscle protein synthesis and the skeletal muscle metabolome of healthy older Danes (> 65 years, 29 females/37 males).
This systematic review and meta-analysis of randomized controlled trials suggests that exercise combined with dietary advice is likely to be a more effective approach for old cancer survivors to improve physical functioning compared with exercise alone.
- This study aimed to evaluate the effect of exercise with or without dietary advice on muscle mass, muscle strength and physical functioning (including perceived physical functioning and physical performance) in old cancer survivors.
- Data from 21 trials were included in this study, including 16 exercise trials and 5 exercise + dietary advice studies.
In this one, after primary treatment for ovarian cancer, those who met or exceeded protein intake recommendations for cancer survivors in general (i.e., >1g/kg) had better progression-free survival than those with lower intake levels.
- This study aimed to investigate whether intake of protein and protein food sources following primary treatment for ovarian cancer is associated with recurrence and survival.
- Those who met or exceeded protein intake recommendations for cancer survivors in general (i.e., >1g/kg) were more likely to have better progression-free survival than those with lower intake levels.
This one found higher dietary intakes of total aromatic amino acids (tyrosine, phenylalanine, tryptophan) to be associated with a lower risk of cardiovascular disease and all-cause mortality in US adults.
- After multivariate adjustment, a higher dietary intake of aromatic amino acids (tyrosine, phenylalanine and tryptophan, or total intake) was associated with a decreased risk of cardiovascular disease mortality.
- When assessed as a continuous variable, each 1 SD increase in the dietary total aromatic amino acids, tyrosine, phenylalanine, or tryptophan intake was associated with a 15%, 15%, 16%, and 15% decrease, respectively, in the risk of cardiovascular disease mortality.
In this one, a greater whole-body protein net balance was observed when protein was evenly distributed between breakfast, lunch and dinner, compared with a skewed protein intake distribution in healthy older adults.
- A greater whole-body protein net balance was observed when protein was evenly distributed between breakfast, lunch and dinner (1/3 of the total daily intake at breakfast, lunch, and dinner)...
...compared with a skewed protein intake distribution (1/6 at breakfast and lunch, and 4/6 of the total daily protein intake at dinner).

This one found no differences in the postprandial rise in muscle protein synthesis rates following ingestion of 30g protein provided either as cheese or as milk protein at rest or during recovery from exercise in healthy, young males.
- The study compared the impact of ingesting 30g protein provided in the form of cheese or milk protein concentrate on postprandial muscle protein synthesis rates in vivo in 20 healthy, young males.
- An increase in circulating amino acid concentrations following the ingestion of 30g protein provided either as cheese or milk protein was observed.
This study sheds doubt on the impact of the food matrix on anabolism, as it found that eating salmon as a whole-food matrix is similarly anabolic compared to ingesting the same nutrients as an isolated mixture of crystalline amino acids and fish oil following resistance exercise.
- The study tried to assess the effects of eating salmon versus ingesting the same nutrients as an isolated mixture of crystalline amino acids and fish oil on the stimulation of post-exercise myofibrillar protein synthesis and whole-body leucine oxidation rates.
- Ten recreationally active adults performed an acute bout of resistance exercise followed by the ingestion of salmon or the isolated mixture in a crossover fashion.
How much #protein do you need?
#WHO says 10-15%, #USDA 10-35% (as most in US consume meat in every meal) and experts like Colin Campbell says 8-10% of your diet should be protein unless child, pregnant or athlete/ lifting weight. Your body is quite good is recycling protein (1/n)

Where to get these proteins from? 70-80% of your protein should be plant based. Plant proteins are packed with rich complex carbohydrates (incl. fibers), healthy fats and antioxidants essential for healthy life.
Below are some of the plant based foods to get your proteins from:

We have previously shown that pre-sleep protein ingestion improves overnight myofibrillar protein synthesis.
In addition, we have shown that long-term pre-sleep protein supplementation improves muscle mass and strength gains.

1. Protein Source.
Eggs are an excellent source of high-quality protein, which is essential for children's growth and development.
In Rwanda, where malnutrition remains a significant problem, eggs can provide children with the nutrients they need to thrive.

2. Nutrient-rich.
Eggs are also rich in essential nutrients such as vitamins A, D, and E, as well as calcium, iron, and zinc, which are vital for building strong bones, boosting the immune system, and supporting brain development.

Teil 10. Thema heute: Proteine. Über kaum ein Thema wird mit Veganern so häufig diskutiert wie über Proteine. "Wo bekommst du denn deine Proteine her?" "Der Mensch braucht tierisches Protein". Immer wieder werden wir mit solchen Aussagen konfrontiert. Doch stimmt das wirklich?
Zunächst zur Theorie: Proteine sind komplexe Moleküle und bestehen aus Aminosäuren. Es gibt 20 Aminosäuren. Ein Teil dieser AS ist essentiell und muss mit der Nahrung aufgenommen werden. Um die Qualität der Proteinversorgung zu beschreiben, benutzt man die biologische Wertigkeit.
Diese BW gibt an, wie gut ein Protein vom Körper verwertet und in körpereigenes Protein umgewandelt werden kann. Grundsätzlich gilt: Je mehr essentielle AS ein Protein enthält, desto höher ist die BW. Als Referenz der BW benutzt man das Hühnerei. Dieses hat eine BW von 100.
The findings of this one suggest that a high adherence to a diet that is rich in protein and unsaturated fatty acids may have beneficial long-term effects on liver fat and lipid metabolism in older subjects.
- An increased intake of protein, total fat, MUFA, PUFA and fiber as well as a decreased consumption of SFAs was achieved in the intervention group.
- Adjusted for baseline intrahepatic lipids, age, sex and BMI change, a reduction of intrahepatic lipids by 33.3% was seen in the intervention group, but the median reduction was not statistically significantly compared to the control group.

#1 - DEI gives way to DEI 2.0 which focuses on Diversity (of perspective), Equality (of opportunity), and Incentives (to do well).
#2 - As education and incomes rise, birth rates plunge. Demographers increasingly worry about an underpopulated planet instead of an overpopulated one.

This one suggests that intermittent fasting with higher-quality, nutrient-dense meals that are evenly spaced throughout the day and provide 20-40g of protein may be superior to a heart-healthy caloric restriction diet in terms of body composition outcomes.
- The IF approach used is a modified IF regimen, which allows consumption of 20% to 25% of energy needs on scheduled fasting days (36-60hrs/wk).
For the rest 5 or 6 days of the week, a meal plan with a macronutrient distribution targeting 35% protein, 35% carbohydrate, and 30% fat was delivered.
