Abstract
Fruits are a cornerstone of human nutrition, providing essential nutrients and bioactive compounds that play a critical role in preventing malnutrition, metabolic disorders, and chronic diseases. This paper examines the systemic impact of dietary fruit intake on human health, focusing on their molecular mechanisms, physiological benefits, and epidemiological evidence. The results of this study indicate that fruits rich in flavonoids (e.g., berries, citrus) and carotenoids (e.g., mangoes, pineapples) neutralize oxidative stress by scavenging ROS and suppressing inflammation via NF-κB/NLRP3 pathways. Dietary fibers from fruits, such as pectin, remodel gut microbiota, enhancing short-chain fatty acid production (e.g., butyrate) and improving metabolic health. Epidemiological studies demonstrate that daily consumption of 200g of fruit reduces cardiovascular disease risk by 12% and type 2 diabetes risk by 7%, with berries showing the strongest protective effects. Additionally, short-term interventions (3–7 days) with specific fruits, like papaya and kiwifruit, rapidly improve digestive and immune functions. These findings underscore the importance of diversified fruit intake tailored to individual health needs, offering actionable strategies for chronic disease prevention and promoting overall well-being.
