A new large cohort study suggests that protein might be healthier than some other nutrients and that plant protein is especially beneficial for lifelong health [1]. How much and from what source? The ideal amount of dietary protein has always been a subject of significant scientific debate. Some scientists claim that the recommended protein intake...

A new study reports a massive 33% increase in median lifespan in male genetically heterogeneous mice following prolonged isoleucine restriction [1]. Not all calories are created equal Caloric restriction is the most powerful life-extending intervention in rodents and primates [2], but the needed magnitude (about 30% fewer calories) is virtually impossible to maintain in humans...

In a new study published in Science, taurine supplementation led to a significant lifespan extension in mice and health benefits in non-human primates [1]. What is taurine? Taurine is an amino acid, but it does not participate in protein building. Instead, it has various other functions, such as helping create bile salts, which is important...

Scientists have found that the tumor microenvironment in lung adenocarcinoma favors methionine-producing bacteria, which, in turn, help the cancer survive nutrient scarcity [1]. Micro-friends or micro-foes? Our bodies host a mind-bending number of microorganisms, but most effects of this cohabitation are not well understood. Scientists have unearthed links between oral and gut microbiota and aging...

In a new study published in Nature Communications, researchers have designed guidelines for dietary amino acid consumption for optimal health [1]. Protein matters Diet is an important component of a healthy lifestyle and is believed to play a major role in health status and longevity. It is also one of the most discussed topics among...

Changing a single amino acid in a single protein boosts the fidelity of protein synthesis, and that is enough to increase lifespan in a variety of organisms, according to new research [1]. Proofreading proteins The loss of proteostasis is one of the hallmarks of aging. However, much of the research on the topic has focused...
