Here we report on a case series of six women who completed a methylation-supportive diet and lifestyle program designed to impact DNA methylation and measures of biological aging. The intervention consisted of an 8-week program that included diet, sleep, exercise and relaxation guidance, supplemental probiotics and phytonutrients and nutritional coaching. DNA methylation and biological age analysis (Horvath DNAmAge clock (2013), normalized using the SeSAMe pipeline [a]) was conducted on blood samples at baseline and at the end of the 8-week period. Five of the six participants exhibited a biological age reduction of between 1.22 and 11.01 years from their baseline biological age. There was a statistically significant (p=.039) difference in the participants' mean biological age before (55.83 years) and after (51.23 years) the 8-week diet and lifestyle intervention, with an average decrease of 4.60 years. The average chronological age at the start of the program was 57.9 years and all but one participant had a biological age younger than their chronological age at the start of the program, suggesting that biological age changes were unrelated to disease improvement and instead might be attributed to underlying aging mechanisms.
我们在此报告了一项关于六名女性的病例系列研究,她们完成了一项旨在影响 DNA 甲基化和生物老化测量的甲基化支持饮食和生活方式计划。该干预措施包括为期 8 周的计划,其中包括饮食、睡眠、运动和放松指导、补充益生菌和植物营养素以及营养咨询。在基线和 8 周后,对血液样本进行 DNA 甲基化和生物年龄分析(基于 Horvath DNAmAge 时钟(2013),使用 SeSAMe 管道 [a] 进行标准化)。六名参与者中有五名的生物年龄从基线生物年龄减少了 1.22 到 11.01 年。参与者的平均生物年龄在 8 周饮食和生活方式干预前后(分别为 55.83 岁和 51.23 岁)存在统计学差异(p=.039),平均下降了 4.60 岁。该计划开始时的平均年龄为 57.9 岁,除一名参与者外,所有参与者的生物年龄都比计划开始时的实际年龄年轻,这表明生物年龄的变化与疾病改善无关,而可能归因于潜在的衰老机制。
