Brussels Sprouts Chips Recipe

If you’re a closet snacker like me, you’ll want to make these chips anytime you buy Brussels sprouts. Whenever I prepare my sprouts for roasting, I cut the stems off right at the base of the baby cabbages and pull off the outer leaves. Nowadays, instead of chucking the leaves into the trash, I toss…


Cinnamon and Nutmeg Spiced Squash Soup

Dr. Jill’s Top Ten Recommended Books for the New Year!

Dr. Jill’s Top Ten Recommended Books for the New Year! I just love new beginnings!  Two-thousand and sixteen was an exceptionally difficult year for me personally.   However, one thing I have learned is that I was born to overcome!  Many of you know I beat breast cancer in 2001 and Crohn’s disease one year later in 2002. (you…


Vegan Eggnog Smoothie

Vegan Eggnog Smoothie There’s something about those flavors of eggnog that are so delicious, but when eggs and dairy don’t work with your tummy anymore, eggnog is the first holiday favorite on the chopping block. It has to be… most recipes require multiple eggs and sometimes two different types of dairy products in order to…


Dr. Jill recently treated a family member for a chronic problem that other doctors were unable to uncover. Her persistence and integrative approach was finally what led to a diagnosis after months of no answers. What was even more amazing was Dr. Jill did this while she was 1000 miles away in a new practice! She was able to offer phone consultations and email communications were always returned quickly. She is top notch!

I wanted you to know that as an Integrative Functional Medicine doctor you are 10 out of 10. In fact I tell people that you are the only one in the USA that could effectively treat my condition, and I really believe that 🙂

I believe that people who go to functional medicine docs are typically desperate. We are the patients who are at the end of our proverbial rope, tired of taking drug after drug with no relief, and who traditional MDs don’t know what to do with. We just dream of a life without pain and to be able to function again. Thanks to Dr. Carnahan, I have no signs of the rheumatoid arthritis I was diagnosed with in 2012, and I’m regaining function that was stolen by the MS I was diagnosed with in 1991. I am recovering and regaining my life. Dr. Jill Carnahan is simply phenomenal.
