Researchers at the University of Alabama at Birmingham found that restricting glucose — the most common dietary sugar — extended the lifespan of healthy human cells in the lab, while precancerous cells behaved differently. The finding ties everyday sugar intake to the machinery of cellular aging.
Why it matters: it’s early, lab-level evidence, but it lines up with the broader theme that chronic excess sugar stresses the body at a cellular level.
