概括
富含多的饮食,包括绿茶和曼开,在临床试验中与缓慢的生物衰老有关. 这表明饮食中的多可能会影响表观遗传年龄和整体衰老过程.
科学领域:
- 表观遗传学和衰老研究.
- 营养科学和代谢
- 微生物群和健康问题
背景情况:
- 通过DNA甲基化进行表观遗传年龄估计,可以提供对生物衰老的见解.
- 以前的研究将多醇摄入量与改善的健康标志物联系起来.
- 富含多的饮食对生物衰老的影响仍未确定.
研究的目的:
- 调查富含多的饮食干预措施对表观遗传年龄的影响.
- 评估地中海饮食 (MED) 和绿色MED饮食后生物衰老标志物的变化.
- 探索饮食,尿液多和生物衰老之间的关联.
主要方法:
- 一个为期18个月的随机对照试验 (DIRECT PLUS) 涉及256名参与者.
- 计算多个表观遗传年龄钟 (例如,Horvath2013,Hannum2013,Li2018) 和DunedinPACE.
- 干预措施包括地中海饮食和富含多的绿色MED饮食,其中包括绿茶和曼开;通过问卷和尿液代谢学评估的坚持.
主要成果:
- 对绿色MED饮食的更强的坚持与Li和Hannum时钟中的降低甲基化年龄 (mAge) 加速相关.
- 更高的曼开和绿茶摄入量与更大的Li mAge衰减有关.
- 尿中多醇 (氧醇,醇,乌罗素C) 的增加与mAge的变化有关;MED式饮食显示Li mAge的8.9个月的差异.
结论:
- 富含多的MED和Green-MED饮食,如绿茶和Mankai,与生物衰老相反地相关.
- 这项研究提供了第一个临床试验证据,表明聚醇摄入量,尿液代谢产物和减少生物衰老之间的联系.
- 饮食干预可以潜在地调节表观遗传衰老过程.

Epigenetic Regulation
3.1K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Aging
72
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

The Effect of Aging on Tissues
2.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
