New theory on how insulin resistance, metabolic disease begin

Does eating too much sugar cause type 2 diabetes? The answer may not be simple, but a study adds to growing research linking excessive sugar consumption — specifically the sugar fructose — to a rise in metabolic disease worldwide. The study, conducted in mice and corroborated in human liver samples, unveils a metabolic process that could upend previous ideas about how the body becomes resistant to insulin and eventually develops diabetes.
