概括
在饮食中发现的植物化合物黄素-3-ols的摄入量较高,与代谢综合征 (MetS) 患者的死亡风险较低有关. 这表明这些化合物对该人口的死亡率有保护作用.
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:
- 代谢综合征 (MetS) 是一个重要的全球健康问题,与增加的死亡率有关.
- 植物性多,特别是flavan-3-ols,具有抗氧化和抗炎性质,可能有利于患有MetS的人.
- 弗拉万-3-消费对MetS人口死亡风险的潜在影响需要进行调查.
研究的目的:
- 调查饮食中的flavan-3-ol摄入量与成年代谢综合征患者全因死亡风险之间的关联.
- 为了检查特定的flavan-3-ol单体与死亡率之间的关系.
- 探索潜在的非线性关联,并在子组中进行修改.
主要方法:
- 分析了2007-2018年国家健康和营养检查调查 (NHANES) 的数据.
- 使用美国农业部数据库量化flavan-3-ol和单体摄入量.
- 考克斯回归,卡普兰-梅尔曲线和限制立方线的应用,以评估死亡率关联.
主要成果:
- 较高的flavan-3-ols摄入量与33%较低的全因死亡风险有关,在最高的三位数与最低的三位数相比 (HR=0.67).
- 特定的单体,如表甲基,显示死亡风险比率降低.
- 没有观察到flavan-3-ol摄入量与心血管死亡率之间有显著的关联,也没有检测到非线性关系或显著的相互作用效应.
结论:
- 在被诊断患有代谢综合征的个体中,饮食中的flavan-3-ol消费与全因死亡风险相反相关.
- 弗拉万-3-ols可能在缓解MetS患者死亡风险方面发挥作用,尽管需要进一步的研究来确认心血管特异性影响.

Cancer Prevention
6.0K
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.

Cholesterol: Significance and Regulation
458
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
