Ever wonder why some teens and adults can do everything ‘right’  – eat great, wash their faces, etc. –  and still have acne? While others can eat pizza three times a day, shower once a week — and end up with perfectly clear skin!…

Leveraging your gut microbiome to change your gene expression

I thought about titling this article ‘going to the dark side’ but decided that bathroom humor should be left behind…. (get it, behind :-)  Enough of the puns and onto the important science stuff that you can actually apply to your life today. There are…

How our genes shape our gut microbiome and our weight

Several studies have come out recently showing that those who are overweight have a different gut microbiome composition than those who are lean.  There have also been interesting mouse studies showing that transplanting feces from obese mice into lean mice causes the lean mice to…

Microbiome + genetics + emulsifiers = obesity

Recently, I listened to an interview (from 2015) of a scientist who did a study on emulsifiers and found that they can lead to low-grade inflammation in the gut, especially in mice with certain immune system genes knocked out. I find the interaction between our…

Genetics and Gum Disease

I read a study last week that piqued my interest in the interplay between genetics and gum disease.  Maybe there is a genetic reason for my tendency towards bleeding gums when the hygienist stabs her probe into them?  I was intrigued to look into…

Are you a non-secretor of your blood type?

FUT2 non-secretor 23andMe

Your genes control the species of bacteria that live in your gut microbiome. And your gut microbiome can help defend against — or make you vulnerable to — chronic diseases. A genetic variant in the FUT2 gene controls whether or not you secrete your…
