Low-protein diets extend lifespan in animals: What it means for human aging research

Pure flour-power. Hearty enough to carry you through lunch.
Summary
The article explores the counterintuitive scientific finding that low-protein diets (around 7% or less of calories from protein) extend lifespan in various animal models, from yeast to insects to rodents. While protein is essential for bodily repair and current US dietary guidelines have actually increased recommended protein intake to 1.2-1.6g per kg body weight, researchers are investigating whether protein restriction could similarly slow aging in humans. The piece examines the biological mechanisms behind this paradox and what it might mean for human longevity.
