In my last post, I caught you up to speed on the concept of epigenetics and why the food you eat gives you the keys to editing those undesirable genes. So you’re probably wondering what to do with this information, and how to practically leverage this good news? Or maybe you skipped the back story and just want me to tell you what to eat, and that’s fair too. Here’s a list of key foods that will help you take control of your health:
Ligands are molecules that binds specifically to a receptor site of another molecule, and in the case of DNA, can alter gene expression of pro-inflammatory genes and pro-inflammatory transcription factors. This means they can act to block the genes that may otherwise promote inflammation in the body, one of the major underlying factors of disease. They include the following bioactive food compounds:
Compounds in food rich in antioxidants and found to protect against disease – best way to get a variety is to eat colorfully!
*there’s still a lot of controversy around soy, but for now, I prefer to sources that are fermented (such as miso), organic, and unprocessed (like edamame)
The second part is a methyl-rich diet, which means getting enough of the micronutrients folate, vitamin B12 & other B Vitamins, specifically 2, 3 and 6, choline, and betaine. The addition of methyl groups to DNA bases have been found to contribute to long-term gene expression, as much as 2 generations. The way you eat today may literally affect your grandchildren!
So as you can see, there’s no “magic formula” to epigenetics- I could have just said “eat more fruits, vegetables, seeds and fish” and left it at that, which you probably already knew (and sounds a lot like the Mediterranean diet, eh? More to come on that). But sometimes you need to know the why behind health advice before you’re convinced to start making changes. So next time you’re planning your meals for the week, think like an artist. More color and variety= healthy gene expression! Check out a few of my favorite ways to incorporate these ingredients:
