Daily Mango Can Improve Blood Glucose Indices, Body Composition in Individuals with Prediabetes

The daily consumption of mango for 24 weeks improved the glycemic control, insulin sensitivity, and body composition in adults with prediabetes, which supports the potential of mango as a practical dietary intervention for metabolic health. Image credit: Mohan Nannapaneni.

In a new study, published in the journal Foods, daily consumption of mango (Mangifera indica) for 24 weeks improved both short- and long-term blood glucose control, reduced insulin resistance, enhanced insulin sensitivity, and promoted favorable changes in body composition among individuals with prediabetes — a condition that, without timely management, can progress to type 2 diabetes, heart disease, and stroke. The findings suggest that incorporating...

Sleep is known to promote tissue growth and regulate metabolism, partly by enhancing growth hormone (GH) release, but the underlying circuit mechanism is unknown. Ding et al. demonstrate how GH release, which is enhanced during both rapid eye movement (REM) and non-REM (NREM) sleep, is regulated by sleep-wake-dependent activity of distinct hypothalamic neurons expressing GH-releasing hormone (GHRH) and somatostatin (SST). SST neurons in the arcuate nucleus suppress GH release by inhibiting nearby GHRH neurons that stimulate GH release, whereas periventricular SST neurons inhibit GH release by projecting to the median eminence. GH release is associated with strong surges of both GHRH and SST activity during REM sleep but moderately increased GHRH and decreased SST activity during NREM sleep. Furthermore, Ding et al. identified a negative feedback pathway in which GH enhances the excitability of locus coeruleus neurons and increases wakefulness.
