High intake of sugar is linked to fatty liver in children as young as nine. Sugar is converted into fat in the liver, leading to non-alcoholic fatty liver disease (NAFLD) or metabolic dysfunction-associated steatotic liver disease (MASLD). The rise in obesity among children, lack of exercise, and easy access to junk food has contributed to the increased incidence of fatty liver. Long-term studies also suggest that poor nutrition during pregnancy can increase the risk of fatty liver in offspring.
