In a new study, the amino acid arginine shows promise in animal models of amyloid aggregation due to its ability to promote protein folding. The researchers suggest that it could be useful for early prevention and treatment of Alzheimer's [1]. Hold it and fold it Amino acids, the building blocks of proteins, can be potent...

A recent study investigated the impact of two amino acids, phenylalanine and tyrosine, on lifespan using UK Biobank data. The researchers reported an association between tyrosine and shorter lifespan, with sex-specific differences. The results for phenylalanine were more inconsistent [1]. One by one Model animal research has shown that protein restriction can extend lifespan. However,...

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...
