Fructose is being studied as a signal, not just a calorie
Dr. Richard Johnson's team published research reframing fructose as a molecule that regulates metabolic health rather than simply supplying energy. Inside the cell, the enzyme fructokinase (KHK) converts fructose into fructose-1-phosphate, a reaction that consumes ATP and is associated with elevated uric acid. Research links that process to lower baseline cellular energy in tissues like the liver, kidneys, vascular system, and parts of the brain. It is a proposed mechanism, not a diagnosis, but it offers doctors and patients a shared variable behind conditions that usually get treated separately.
