Increased circulating levels of branched-chain amino acids (BCAAs) and imidazole propionate, linked to gut microbiota function, are associated with insulin resistance and higher risk of type 2 diabetes.

High levels of certain metabolites like BCAAs and imidazole propionate in your blood are linked to insulin resistance. These are partly produced by your gut bacteria, suggesting that a balanced diet supporting a healthy microbiome is important for metabolic health.

GoodSupportsHIGH confidence
Increased levels of circulating BCAAs have been described in insulin-resistant individuals and linked to a higher risk of type 2 diabetes (19). Furthermore, increased plasma levels of imidazole propionate, a bacterial product of histidine metabolism, have been reported in individuals with insulin resistance and type 2 diabetes (48).
