A recent study published in Nutrients suggests that regular mango consumption may improve inflammation, insulin sensitivity, and glucose control in overweight individuals. The study found that participants who consumed mangoes twice daily for four weeks showed lower fasting insulin levels and improved insulin sensitivity compared to those who consumed a control product.

Dietary approaches to manage inflammation Chronic low-grade inflammation is associated with an greater risk of developing metabolic syndrome and type 2 diabetes mellitus due to associated blood glucose dysregulation, thereby increasing the risk of cardiovascular disease, cognitive impairment, and other complications. Obesity, which affects 12.5% of the global population, is characterized by low levels of inflammation. About 6% of obese individuals are also diagnosed with T2DM, with 9% considered pre-diabetic due to the presence of abnormally high blood glucose levels. Obese individuals who lose 5-10% of their body weight can experience significant improvements in their metabolic status and inflammation. Likewise, the incorporation of anti-inflammatory food products can also help manage metabolic disease. Mangoes contain abundant fiber, micronutrients, and bioactive compounds. Regular mango consumption is associated with lower body weight, body mass index values, and waist circumference measurements, as well as better diet quality and glucose tolerance. To date, few studies have examined how mango consumption contributes to blood glucose regulation. About the study The current study determined the effect of regular mango intake on chronic low-grade inflammation and insulin sensitivity in obese or overweight people. To this end, 48 obese or overweight people with a mean age of 37.6 years were enrolled in a randomized controlled trial. Related StoriesAll study participants completed a two-hour oral glucose tolerance test at baseline. Thereafter, study participants were randomized to consume one cup of either mango or a control product in their diet twice daily for four weeks. OGTT was repeated at the end of the intervention period. Mango intake and inflammation Regular mango consumption did not significantly affect any inflammation marker including interleukin -6, tumor necrosis factor α , or C-reactive protein . Body weight increased in the control group after the intervention but not individuals who consumed mangos. Mango intake and blood glucose The average fasting glucose levels did not significantly change with mango intake. Fasting insulin levels were lower after four weeks in those who consumed mangos as compared to controls beginning from week one and persisting after the end of the intervention. Mango consumption and insulin Insulin levels were lower four weeks after beginning the intervention in the mango-consuming group as compared to controls and their baseline levels. No change in insulin levels was observed in the control group. The Homeostasis Model Assessment of Insulin Resistance measures insulin response in the liver, which produces glucose in the fasting state. The disposition index , which assesses pancreatic beta cell function, was also measured to determine the extent to which mango consumption affected glucose levels. Both HOMA-IR and DI scores significantly and consistently improved in the mango intake group. At the end of four weeks, HOMA-IR and DI scores were 2.3 and 2.8 in the mango group, respectively, whereas control scores were 4.7 and 5.4, respectively. Systemic insulin resistance was reduced after mango intake; however, the difference between the groups was not significant. Gene expression unchanged Despite a two-fold increase in the expression of the nuclear factor erythroid 2-related factor 2 gene, which controls antioxidant activity, this effect was not statistically significant. The relative expression of Toll-like receptor 2 and TLR4, both of which are involved in cellular responses to different pathogens, did not significantly change following mango consumption. Conclusions The study findings suggest that regular mango consumption improves glucose regulation by increasing insulin sensitivity at the hepatic and pancreatic levels, thus reducing the amount of insulin required to maintain normal glucose levels. The improved glycemic control may be due to more effective endogenous antioxidant activity, which is related to higher insulin sensitivity. The improved glycemic control in mango consumers supports previously reported findings. Moreover, the lack of significance in several parameters could be due to the relatively short study duration. The data support consuming mango fruit as part of a dietary pattern to address insulin resistance and warrant further research to understand the mechanisms underpinning the actions of mango intake.”

Plant-Based Milk Linked to Higher Depression Risk, Dairy Consumption May ProtectA new study suggests that individuals who consume plant-based milk alternatives like soy or oat milk may have a higher risk of depression. Conversely, those who drink semi-skimmed dairy milk appear to have a lower risk of both anxiety and depression. Researchers analyzed data from over 350,000 participants in the UK Biobank over a decade, taking into account factors like age, physical health, and income. The study suggests a potential link between dairy-based milk's calcium content and serotonin production, which plays a role in mood regulation.
