The role of metabolomics in the field of nutrition is continuing to grow and it has the potential to assist in the understanding of metabolic regulation and explain how minor perturbations can have a multitude of biochemical endpoints. It is this development, which creates the potential to provide the knowledge necessary to facilitate a more targeted approach to nutrition. In recent years, there has been interest in applying metabolomics to examine alterations in the metabolic profile according to weight gain/obesity. Emerging from these studies is the strong evidence that alterations in the amino acid (AA) profiles are associated with obesity. Several other studies have also shown a relationship between branched-chain amino acids (BCAA), obesity and insulin resistance. The present review focuses on the proposed link between AA and in particular BCAA, obesity and insulin resistance. In conclusion, a wealth of information is accumulating to support the role of AA, and in particular of the BCAA, in obesity.

Circulating levels of branched chain amino acids (BCAAs) correlate strongly with type 2 diabetes (T2D). The correlation may be associated with insulin-resistance factors independent of glycemic markers currently used in the diagnosis and monitoring of diabetes. This can revolutionize the thought process and methodology not only in diabetes treatment, but also in its advance screening and prevention with BCAAs used as biomarkers and targets for treatment. Whether insulin resistance is the cause or result of BCAAs imbalances requires further investigation. Although the overall diet is important, the role of specific diets targeting the gut microbiome composition and hormone secretion affecting BCAA absorption and metabolism will be explored. Generic diet modifications apparently induce only negligible changes in the intrinsic genetic make-up of the gut and BCAA levels but influence specific modulation of the gut microbiome. This genetic make-up is indeed similar among T2D patients independent of numerous variables including obesity. Short-chain fatty acids (SCFAs), the primary end-products of non-digestible carbohydrates (NDC) fermentation, mediate metabolic imbalances through gut microbiota and gut hormone secretion. This review focuses on extensive evidence gathered using diverse methodologies on the strong parallel correlation between BCAA levels and insulin resistance. Furthermore, the role of specific diets particularly SCFAs as mediators of the stubbornly fixed intrinsic genetic make-up of gut microbiota will be scrutinized to delineate BCAA levels and insulin resistance in T2D.

Abstract BACKGROUND The role of branched-chain amino acids (BCAAs) in cardiovascular disease (CVD) remains poorly understood. We hypothesized that baseline BCAA concentrations predict future risk of CVD and that a Mediterranean diet (MedDiet) intervention may counteract this effect. METHODS We developed a case-cohort study within the Prevención con Dieta Mediterránea (PREDIMED), with 226 incident CVD cases and 744 noncases. We used LC-MS/MS to measure plasma BCAAs (leucine, isoleucine, and valine), both at baseline and after 1 year of follow-up. The primary outcome was a composite of incident stroke, myocardial infarction, or cardiovascular death. RESULTS After adjustment for potential confounders, baseline leucine and isoleucine concentrations were associated with higher CVD risk: the hazard ratios (HRs) for the highest vs lowest quartile were 1.70 (95% CI, 1.05–2.76) and 2.09 (1.27–3.44), respectively. Stronger associations were found for stroke. For both CVD and stroke, we found higher HRs across successive quartiles of BCAAs in the control group than in the MedDiet groups. With stroke as the outcome, a significant interaction (P = 0.009) between baseline BCAA score and intervention with MedDiet was observed. No significant effect of the intervention on 1-year changes in BCAAs or any association between 1-year changes in BCAAs and CVD were observed. CONCLUSIONS Higher concentrations of baseline BCAAs were associated with increased risk of CVD, especially stroke, in a high cardiovascular risk population. A Mediterranean-style diet had a negligible effect on 1-year changes in BCAAs, but it may counteract the harmful effects of BCAAs on stroke.

AbstractThe mammary gland, a unique exocrine organ, is responsible for milk synthesis in mammals. Neonatal growth and health are predominantly determined by quality and quantity of milk production. Amino acids are crucial maternal nutrients that are the building blocks for milk protein and are potential energy sources for neonates. Recent advances made regarding the mammary gland further demonstrate that some functional amino acids also regulate milk protein and fat synthesis through distinct intracellular and extracellular pathways. In the present study, we discuss recent advances in the role of amino acids (especially branched-chain amino acids, methionine, arginine and lysine) in the regulation of milk synthesis. The present review also addresses the crucial questions of how amino acids are transported, sensed and transduced in the mammary gland.
