概括

坚持健康的植物性饮食 (hPDI) 显著降低死亡风险. 相反,不健康的植物性饮食 (uPDI) 会增加死亡率,这凸显了饮食质量对长寿的重要性.

科学领域:

营养科学营养科学
流行病学流行病学
公共卫生公共卫生

背景情况:

植物性饮食与长寿和减少与生活方式相关的疾病有关.
关于植物性饮食指数 (PDI,hPDI,UPDI) 和死亡风险的先前研究表明结果不一致.
需要进行元分析来巩固证据并探索剂量反应关系.

研究的目的:

总结植物性饮食模式 (PDI,hPDI,UPDI) 与死亡风险之间的关联.
量化这些饮食模式和死亡率之间的剂量反应关系.
提供关于植物性饮食和死亡率的当前证据的全面概述.

主要方法:

在2024年10月之前对队列研究进行系统审查和元分析.
在PubMed和Scopus进行文献搜索.
计算聚合风险估计 (RR) 和PDI,hPDI和UPDI的剂量反应分析.

主要成果:

包括11个队列研究 (13个数据集).
较高的PDI和hPDI遵守率与明显较低的全因死亡率相关 (HR=0.85和HR=0.86,分别).
对UPDI的更高遵守与所有原因死亡率显著增加有关 (HR=1.20).
在PDI/hPDI和死亡率之间观察到非线性关系,但不是PUDI.

结论:

更多地坚持PDI或hPDI与降低死亡风险有关.
不健康的植物性饮食模式 (uPDI) 与死亡风险有关.
促进健康的植物性饮食是公共卫生和降低死亡率的关键战略.

Cancer Prevention

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Overview of Metabolism

Overview of Metabolism

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...
