《2015-2020年膳食指南》支持地中海饮食，将其作为一种饮食模式的范例，在整个生命周期中促进身体健康、保持健康体重和预防疾病。地中海饮食模式以各种未经加工的植物性食物为基础，包括水果、蔬菜、全谷物、豆类、坚果和富含多酚的种子。大多数多酚到达结肠，细菌将其降解成更小的酚类物质，可通过门静脉转运到肝脏。在肝脏中，酚类物质在释放到血液循环和运输到特定组织之前经历额外的生物转化，在这些组织中，生物活性作用在尿液中去除之前发生。最近的流行病学研究使用改进的评估技术支持高与低饮食多酚摄入量可以降低神经退行性疾病、糖尿病、心血管疾病、高血压、肥胖和各种原因导致的早期死亡的风险。新兴科学表明，许多与健康相关的益处可以追溯到生物转化的肠道衍生酚类物质。总之，地中海沿岸国家的居民大量食用未经加工的植物性食品，这在很大程度上与多种健康和疾病预防益处有关，这在很大程度上是由于多酚的摄入量不同。
The Mediterranean diet is upheld in the 2015–2020 Dietary Guidelines as an example of an eating pattern that promotes good health, a healthy body weight, and disease prevention throughout the lifespan. The Mediterranean eating pattern is based on a variety of unprocessed plant foods including fruits, vegetables, whole grains, legumes, nuts, and seeds that are high in polyphenols. The majority of polyphenols arrive in the colon where bacteria degrade them into smaller phenolics that can be translocated via the portal vein to the liver. In the liver, the phenolics undergo additional biotransformation prior to release into the circulation and transport to specific tissues where bioactive effects take place before removal in the urine. Recent epidemiologic studies using improved assessment techniques support that high versus low dietary polyphenol intake predicts reduced risk for neurodegenerative diseases, diabetes, cardiovascular disease, hypertension, obesity, and early death from all causes. Emerging science reveals that many of these health-related benefits can be traced to the biotransformed, gut-derived phenolics. In conclusion, the high consumption of unprocessed plant foods by inhabitants of countries bordering the Mediterranean Sea has been linked to multiple health and disease prevention benefits that are in large part due to a varied intake of polyphenols.
