The Importance of Methylation in Aging

Methylation plays a crucial role in controlling gene expression and aging. Our genetic material is static, but the wrapping and unwrapping of DNA around histones (proteins) determine which genes are expressed. Methylation, the addition of a methyl group to DNA, acts as punctuation, instructing genes to turn on or off. As we age, methylation patterns change, leading to a breakdown in gene regulation and an increased risk of chronic diseases. Lifestyle factors such as diet and stress can influence methylation, highlighting the importance of maintaining a healthy methylation cycle through nutrient-rich foods like leafy greens, mushrooms, liver, eggs, and fatty fish. Additionally, polyphenols found in colorful fruits and vegetables, such as blueberries and turmeric, may contribute to optimal gene expression through their ability to direct DNA methylation.
