Title : Impacts of foods rich in bioactive compounds on diabetic microvascular complications
Abstract:
Diabetes is a major community health issue in the world, with a prevalence of 537 million adults, and an estimated prevalence of 783 million cases by 2045. It is noteworthy that every 1 in 10 individuals suffers from diabetes. Diabetic microvascular complications, including retinopathy, nephropathy, and neuropathy, remain a significant global health issue, even with advanced medical treatments. Functional foods rich in bioactive compounds such as polyphenols, omega-3 fatty acids, and probiotics have emerged as key factors in reducing oxidative stress, inflammation, and endothelial dysfunction, which are the main drivers of microvascular damage. This study presents a systematic review of trials examining the impact of functional foods on the prevention or lessening the incidence of diabetic microvascular complications. The data was searched across Google Scholar and PubMed involving interventions, functional foods, or fortified foods. A pooled analysis showed a significant improvement, such as lower HbA1c levels, Better lipid profiles, and reduced oxidative stress markers. A clinical trial showed improvement among 150 individuals taking functional foods rich in bioactive substances such as omega-3 fatty acids, polyphenols, Probiotics, and fiber over 12 weeks, and it showed a significant result in fasting blood glucose from 168.4 ± 25.7 mg/dL to 144.2 ± 19.5 mg/dL (p < 0.001) and HbA1c (8.3 ± 0.6 to 7.4 ± 0.5, p < 0.001). Additionally, there were also noticeable improvements in lipid profile and inflammatory markers (p < 0.05). The ginger trial also showed significant improvement in 45 participants over 3 months, Serum glucose -19.41 ± 18.33 mg/dL vs. +1.63 ± 4.28 mg/dL (placebo) and HbA1c -0.77 ± 0.88 vs. +0.02 ± 0.16 (placebo). Whereas, the resveratrol trial among 57 individuals over 3 months shows significant results in fasting glucose -14.39 ± 5.05 mg/dL vs. + 13.07 ± 6.34 mg/dL in control and HbA1c -0.33 ± 0.04 vs. +0.17 ± 0.10 in control. The findings highlighted functional foods as an affordable and culturally relevant option to support adaptable strategies. Future Direction will explore more large-scale, longitudinal studies and subgroup clinical trials with specific foods comparison, like berries or green tea, which improve diabetic complications, and micro- or nanotechnology-based delivery systems to improve the bioavailability and personalized nutrition approaches for genetic and metabolic profiles. It is the need of time to incorporate this into policy guidelines, especially in resource-limited settings to get the full extend benefit of this readily available, GRAS status and economical option to mitigate the current challenge related to population health.
