About
I'm a 54-year-old mom from the Midwest. I'm not a doctor. I don't have a medical degree. What I have is a stubborn streak and an internet connection — and after a blood sugar scare a few years ago, I started doing what I do best: digging in.
At 52, my doctor told me my fasting blood sugar was in the pre-diabetic range. I'd been eating what I thought was healthy — whole grains, lean protein, the usual advice. My numbers didn't care.
So I started reading. Not the front-page health articles that tell you to "eat less and move more." I went deeper — PubMed studies, clinical trials, research journals. I wanted to understand why my body was doing what it was doing.
What I found surprised me. Some of it even frustrated me, because it wasn't complicated — it just wasn't being talked about in plain language. The research was there, but it was buried behind paywalls and medical jargon.
This site is where I share what I've found. Every article cites its sources. Every claim links back to published research. I try to explain things the way I wish someone had explained them to me — clearly, honestly, and without trying to sell you on a miracle cure.
This is an independent research site. I read studies, summarize findings, and connect dots between different areas of health — particularly blood sugar, metabolism, nerve health, and aging. I focus on the topics that matter to people like me: women (and men) over 40 who want real information, not marketing hype.
When I find a product or supplement that has research behind it, I'll tell you about it. Some of those are affiliate links, which means I earn a small commission if you decide to purchase. That's how I keep this site running. But I'll never recommend something just because it pays well — my credibility is worth more than a commission check.
Every article on this site follows a simple set of rules:
I cite my sources. If I reference a study, I link to it or identify it clearly so you can look it up yourself. I distinguish between established science and emerging research. If something is promising but not conclusive, I say so. I never claim to have medical expertise I don't have. I'm a researcher and a reader — not a physician, nutritionist, or dietitian.
I update articles when new research comes out. Health science evolves, and what we knew five years ago may not be the full picture today.
