First, learn about methylation & the nutrients involved in methylation here.
We are what we eat. Literally. What we eat can potentially “turn on” or inhibit the expression of certain genes. Think epigenetics —> organism changes caused by modification of gene expression rather than alteration of the genetic code itself. DNA methylation is an example of this (a biochemical process discussed in the previous post). Methylation is a major player in altering gene expression to cope with stressors from our environment, with the ability to “turn on” or “turn off” biological switches, impacting our body’s responses. As an example, decreasing the likelihood of, say, tumor growth or cancer by “turning off” a certain gene. It is pretty cool that we can potentially affect these processes in some manner, particularly via diet. DNA methylation is affected most by the following nutrients: • Methionine • Glycine • Betaine/Choline • Vitamin b12 • Folate b9 • B vitamins (1, 2, 3, 6) Increasing each of these nutrients in your diet can potentially assist DNA methylation (cool!!). On the flip side, being deficient can lead to depletion of other nutrients, toxic byproducts, & reduced longevity (not cool) by inhibiting the process of methylation from functioning properly. View the images below for rich sources of each nutrient. The amounts listed are based on consuming the minimum RDA per day (which should be taken with a grain of salt). There are several things that will impact your needs: health status, absorption capacity, genetics.
Without stressing about hitting these amounts perfectly, instead, aim to increase the amount of each nutrient to nurture methylation.
View here to learn about the methionine to glycine ratio, a ratio that’s particularly important to consider when aiming to nurture methylation.
