Summary: The vast majority of people with diabetes are patients with type 2 diabetes. Before this disease develops, there is a prediabetes condition that is potentially reversible. By changing behavioral habits and taking certain medications, it is possible to effectively prevent the development of type 2 diabetes. The role of zinc in metabolic processes is being analyzed in an increasing number of studies. Research shows that zinc can be a valuable adjunct to type 2 diabetes therapy and support patients with prediabetes status in the fight against insulin resistance.
