In a new study, a team led by Assistant Professor Yoshitaka Kondo investigated the amount of dietary protein needed to improve metabolic health in mice approaching old age.
The team recruited young (6 months old) and middle-aged (16 months old) male C57BL/6NCr mice who were fed isocaloric diets with varying protein content (5 to 45 %) for two months. After two months, the effect of varying protein diets was assessed based on measurements of skeletal muscle weight, liver and plasma lipid profiles, and self‑organizing map (SOM) cluster analysis of plasma amino acid profiles.
The team observed that the consumption of a low-protein diet led to the development of mild fatty liver, with increased levels of hepatic lipids in middle-aged mice as compared to young mice. In contrast, a moderate-protein diet led to reduced blood glucose concentrations and lipid levels in both liver and plasma. These findings indicate that a moderate-protein diet (25% and 35%) kept both young and middle-aged mice metabolically healthier.
On examining the effect of varying protein diets on plasma amino acid concentrations in mice of both age groups, the researchers observed that the plasma concentration of individual amino acids varied with age and varying dietary protein content. Furthermore, the plasma amino acid profiles revealed using SOM analysis showed the correlation between different protein intake and the varying amounts of hepatic triglycerides and cholesterol levels.
Kondo remarks, "Protein requirements change through the course of life, being higher in younger reproductive mice, reducing through middle age, and rising again in older mice as protein efficiency declines. The same pattern is likely to be observed in humans. Therefore, it could be assumed that increasing daily protein intake in meals could promote metabolic health of people. Moreover, ideal dietary macronutrient balance at each life stage could also extend health span."

Many critical processes depend on the amino acids that make up proteins.
They recruited the mice? How?
We need fiber and veges, but protein diets are life.
I laugh at the vegans who stuff themselves full of vegetables and carbs - like cows - then wonder why they’re slow and fat.
A person needs protein for brain development and thus critical thinking. Anyone who is recommending a low protein diet wants you compliant and easy to control.
“Protein is the second largest matter in the brain, second only to water, so it is important to nourish your brain with protein rich foods. Proteins help neurons within the brain communicate with each other through neurotransmitters that are made from amino acids.”
All you have to do is observe design of teeth in any mammals to know how they evolved. If large canines are present (tigers, leopards) then you are designed to eat more meat proteins. If canines are not prominent and have good sized molars humans), then you evolved eating a mixed diet.
Another good indication is length of small intestine. Carnivores have much shorter intestines than herbivores (deers, cows). Humans are again somewher in the middle between the two.
We do not need to fund studies examining mice to know whats best diet. Just observe your anatomy.
Elephants have larger brains than humans and they never eat meat protein.
They can digest cellulose, can you?
We evolved as omnivores: meat, eggs, fruits, veggies.
Grain is a relatively recent addition to our diets. It provides cheap calories but fewer essential nutrients.
I’m trying to keep my bread/pasta levels low.
Non sequitur response. We were debating need to eat animal protein for brain function. Elephants have good functioning brains without any animal protein.
Tell that to the WEF, and the United Nations 2030 Agenda crowd, and other organizations that want us to eat insects.
Protein is brain food and is necessary among humans for survival and brain enrichment.
We stop efficiently using and making proteins, as we age.
Many critical processes depend on the amino acids that make up proteins.

DHEA supplementation helps. As we age the adrenal glands reduce production of critical hormones which stimulate cellular processing of amino acids. DHEA is the body’s adrenal anabolic steroid which stimulates proper release and uptake of these hormones. DHEA production fades with age.
You are correct. Grains were produced by agriculture going back only 15,000 years. Humans and humanoids have been around much longer by orders of magnitude.

The superior intelligence of humans shows just how little good this aspect does for elephants. They can’t even pronounce or spell intelligence.

Humans are Humans because of our ability to eat grains.
Over 2.5 million years (25 ice ages) ago humans evolved from primates which randomly started releasing DPPIV into their intestines. The mutation allowed hominids to grow and eat grains in agricultural communities, just like today. I can tie the rapid evolution of hominids to the subsequent release of zonulin into the intestines as a “viral marketing” strategy to induce epidemics and accelerate the process of evolution.
Cool, grabbed a leg of lamb today.
Have archeologist found evidence of tranny cave women (men pretending their women) millions of years ago?

"Who knows? It might eventually cure the common cold, but lengthen lives? Poppycock! I can do more for you if you just eat right and exercise regularly."
You brought up animal protein, the article just references protein. There is plenty of protein in the grasses and leaves and bushes elephants eat. There is minimal protein in fruit but elephants eat that too.
Research has shown that all plants contain protein and at least 14% of the total calories of every plant are protein.
