As the name implies, spermidine was first characterized in sperm, and while there is a high concentration present in semen (and it appears important for fertility), it’s everywhere- in all eukaryotic cells. In fact, wind the evolutionary clock back to…
In the pursuit of wellness and longevity, skin health often mirrors the body’s internal state, serving as a visible testament to our overall well-being. Yet, traditional approaches to skincare have predominantly focused on treating the surface, neglecting the deeper cellular…
This quick gluten-free, yeast-free bread recipe requires very little effort and is a pleasantly tasty surprise. Plus it’s main ingredient – sunflower seeds – are a Younger You longevity superfood. Seeds (and nuts) are powerhouses of DNA methylation (and therefore…

This blog was written by Romilly Hodges MS CNS CDN IFMCP Last month I was honored to be invited to speak at the American Nutrition Association annual summit on the topic Targeting Biological Age with Diet and Lifestyle. Not…
Only 5% men and 9% of women are getting the recommended daily amount of fiber in the United States.[1] That’s almost 90% of the population not consuming enough fiber! To put this into perspective, in 2017–18 most Americans averaged 8.1…
This is a great, family-friendly weeknight meal – the sauce melds with the cauliflower rice in a way that even picky eaters shouldn’t care that it’s not actual rice. Or, if you’re cooking for one, it’s tasty enough that you’ll…
I am particularly interested in nutrient responsive genes, especially for altering the risk for and course of conditions such as breast cancer. Nutrient responsive genes, as their name implies, are those whose expression responds to their environment – specifically the…
Over the last decade, there has been an explosion of research looking at bioenergetics (energy metabolism) and the role our energy generators – the mitochondria – play in human health and longevity. In functional medicine, we’ve long been aware of…
Acute illnesses like seasonal colds carry a heavy socioeconomic burden and impact livelihood in many ways, taking a great toll on society including children, families, and the medical community. This results in increased direct costs (e.g., clinic visits, drug consumption,…
Midlife is an extremely active time epigenetically. Pro-inflammatory genes tend to become hypomethylated and get ramped up, tumor-suppressor genes can become progressively more silenced, genes that code for antioxidant and detoxification enzymes such as glutathione transferase (which also happens to…
Weight gain is one of the most frequently seen complaints during perimenopause and menopause. In this blog we will explore why that is and how the female body changes during this magical and yet confusing life stage. Menopause and perimenopause…

In my first year of naturopathic medical school, stuck right in the middle of the standard basic science classes, was a class on hydrotherapy- evidence of how fundamental the use of hot and cold water as a healing modality was…
Last month, I was awarded the Rosalind Franklin Society Special Award in Science for my research on using a diet and lifestyle program to favorably change DNA methylation and reverse biological aging. I’m humbled and honored to receive this award,…
Mushrooms are a powerful, and often underutilized, tool for health and longevity. They provide important nutrients, including those used in methylation cycles- folate, choline, and zinc for example. Their bioactive compounds also act as DNA methylation adaptogens, with the ability…
Eggs are one of those controversial foods that we were warned against for almost half a century. However, recent years have seen both the American Heart Association and Dietary Guidelines for Americans reverse their restrictions on eggs and dietary cholesterol…
Dr. Fitzgerald is an internationally-recognized expert clinician, as well as nationally-bestselling author, who is actively engaged in clinical research on epigenetics and longevity using a diet and lifestyle intervention developed in her research and practice.
She has published two clinical studies on the potential bioage-reversing effects of an 8-week DNA methylation-supportive diet and lifestyle in middle-aged men and women in the journal Aging. She continues to lead the conversation around interventions for healthy aging and their extensive potential in improving individual and population level disease burdens, while also providing evidence-based and practical advice that cuts through the hype.
Dr. Fitzgerald is on faculty at the Institute for Functional Medicine (IFM), is an IFM Certified Practitioner, and lectures globally on functional medicine, longevity, and epigenetics to practitioners and consumers.
She maintains an award-nominated podcast series ranked in the top 1% of global podcasts by Listen Score, New Frontiers in Functional Medicine, and an active blog and Clinic Immersion webinar series through her website, www.drkarafitzgerald.com.
