Core Viewpoint - The article emphasizes the potential health benefits of mango consumption, particularly its role in improving insulin sensitivity and metabolic health in overweight or obese individuals with chronic low-grade inflammation [3][10]. Summary by Sections Blood Sugar Regulation - Blood sugar is a crucial health indicator, with normal fasting levels between 3.9-6.1 mmol/L and postprandial levels not exceeding 7.8 mmol/L. Dietary choices significantly impact blood sugar control, where a balanced diet stabilizes blood sugar, while poor eating habits can lead to spikes [3]. Mango's Nutritional Benefits - Mango is highlighted for its high dietary fiber content and various vitamins and minerals. Previous studies have shown that moderate mango intake may positively affect blood sugar regulation and inflammation [3][10]. Clinical Study Overview - A recent randomized, placebo-controlled trial involved 48 participants with specific metabolic characteristics, including a BMI of ≥25 kg/m² and fasting blood glucose levels between 100-126 mg/dL. Participants were divided into two groups: one consuming fresh mango (approximately 230 grams daily) and the other receiving a mango-flavored placebo drink [6][7]. Study Findings - After four weeks, the study assessed blood sugar control using the oral glucose tolerance test (OGTT) and measured various metabolic parameters. Results indicated that regular mango consumption significantly improved insulin sensitivity, evidenced by decreased fasting insulin levels and improved HOMA-IR index [7][9]. Inflammation Markers - No significant statistical differences were found in inflammation markers between the mango and control groups, suggesting that mango's effect on insulin sensitivity may not directly involve inflammation pathways. The study primarily focused on IL-6, TNF-α, and hs-CRP, leaving out other relevant inflammatory markers [8]. Nrf-2 Gene Expression - An interesting finding was the approximately twofold increase in Nrf-2 gene expression in the mango group, although not statistically significant. Nrf-2 is crucial for activating antioxidant genes, which may enhance cellular antioxidant defenses and alleviate oxidative stress, potentially explaining the improvement in insulin sensitivity [9][10]. Conclusion and Future Research - The study concludes that mango, rich in active polyphenols and antioxidants, may serve as a dietary intervention for improving insulin resistance. Further research is recommended to explore the mechanisms and broader health benefits of mango consumption [10][11].

Core Viewpoint - The article emphasizes the potential of strawberries as a dietary intervention for managing prediabetes and improving metabolic health, supported by clinical research findings that demonstrate significant benefits in blood sugar control and cardiovascular health indicators [4][11][17]. Group 1: Clinical Research Findings - A recent clinical study published in *The Journal of Nutrition* indicates that consuming 2.5 servings of strawberries daily for 12 weeks significantly improves blood glucose metabolism and various cardiovascular metabolic indicators in adults with prediabetes [4][11]. - The study involved a randomized controlled trial design, confirming a causal relationship between strawberry intake and metabolic improvements, rather than mere correlation [4][9]. - Key metabolic improvements observed include an average reduction of 8.9 mg/dl in fasting blood glucose, a 0.2% decrease in glycated hemoglobin, and a 6.9 μIU/ml reduction in serum insulin levels [11]. Group 2: Mechanisms of Action - Strawberries contain various bioactive compounds, such as anthocyanins and ellagic acid, which may enhance insulin sensitivity and reduce chronic inflammation, critical factors in the development of type 2 diabetes [4][13]. - The health benefits of strawberries are attributed to their high polyphenol content, which exhibits antioxidant properties, reduces oxidative stress, and modulates inflammatory pathways [14][15]. - Strawberries also improve lipid metabolism by downregulating key enzymes involved in fat synthesis, leading to favorable changes in cholesterol levels [15]. Group 3: Practical Implications - From a public health perspective, strawberries could provide a palatable and sustainable dietary option for high-risk populations to prevent diabetes [5][17]. - Recommendations suggest a daily intake of approximately 250-300 grams of fresh strawberries for individuals with prediabetes, emphasizing the importance of incorporating them into a balanced diet [16]. - The article highlights the need for further research with larger sample sizes and longer observation periods to establish optimal intake levels and long-term effects of strawberries on metabolic health [5][16].
