Title: Impact of branched-chain amino acid (bcaa) intake on type 2 diabetes mellitus


Elevated circulating levels of branched-chain amino acids (BCAA) have been described as a strong predictor of type 2 diabetes mellitus (DM2) because of their involvement in insulin resistance (IR). The main objective is to evaluate whether a diet rich in these amino acids poses a risk for the development of DM2. This literature review was based on scientific articles selected from different databases, including PubMed. A total of 23 articles were studied in depth. A higher intake of BCAA has shown a positive association in the development of DM2, mainly if it comes from foods of animal origin. Likewise, its selective restriction produces a certain improvement in the pathophysiology of DM2 without compromising the intake of other essential nutrients. On the other hand, BCAA supplementation protocols have not been observed to have negative repercussions on health.  BCAA intake does seem to be associated with an increased risk of DM2; however, this association cannot be studied in isolation, but should be considered part of a complex interaction of dietary components, in which the nutritional quality of the food plays an important role.
