Dogs in the Home Help Shape Children’s Immune Systems

Dogs not only serve as playful and loving family companions, but now research suggests they also help keep kids’ immune systems healthy.

A study found pregnant moms with a dog in the home had children with less immunoglobulin E (IgE) allergies. Adolescents who had prenatal exposure to dogs showed nearly a 30% decrease in IgE trajectory levels compared to adolescents whose mothers did not have a dog while pregnant (p=0.0005). Higher IgE levels are associated with conditions such as eczema and asthma.

The benefit to a child’s immune systems may in part be due to dogs bringing bacteria into the home, which likely impacts the gut microbiome. We always love learning about the various ways to influence gut health and the immune system. Dog adoptions have increased during the pandemic to help with social isolation and wellbeing – perhaps this research offers another reason to include a furry friend in your family!

The info you are putting out is awesome. You’re playing an enormous role in helping so many practitioners and people to better understand the immune system and all the wonderful bioactives and lifestyle modifications that can make a difference. Thanks for all the time, effort, and research that you put in on a daily basis to help others. You should certainly be proud of what you do.

Dr. Fitzgerald’s book is an extraordinary integration of a vast amount of diverse information that makes practical sense of the complex interplay between our genes, the folate/vitamin B12 cycle, homocysteine, and the clinical importance of methylation.

I was thrilled to see the principles of a methylation food plan. This helped to confirm my teaching principles.

The nutrition methylation webinar has fabulous information on methylation and specific nutrients that are required to support the process. I think I can speak for our team of dietitian nutritionists in saying that it is valuable to connect the science and biochemistry from Dr. Fitzgerald’s point of view with the nutrition and implementation from Romilly. They are a knowledgeable team! I love that this is a food-first approach with an emphasis on food and dietary intervention for sustainable long-term nutritional support. Food is not just medicine, it’s information for methylation and you can’t supplement your way out of a bad diet!

Brigid Titgemeier, MS, RDN, LDCleveland Clinic Center for Functional Medicine

I enjoyed the presentation and really appreciated the food first approach. There were many talking points to help solidify this concept with patients, particularly those that don’t “buy in” to the food first approach or simply want to take a supplement.

Dr. Kara Fitzgerald always produces clinically relevant and compelling cutting-edge content in her blogs, PodCasts and newsletters and I try to never miss one. Her dept of knowledge in the functional medicine paradigm and its relevance to modifying the course of the chronic disease epidemic is not only valuable, but inspiring. She is a respected colleague and I always appreciate the effort she puts into keeping up the important dialogue between integrative and functional medicine clinicians, as well as her clear desire to educate the health care consumer in the process.

I’ve had the opportunity to review Dr. Kara Fitzgerald’s blogs. She is a well-recognized leader of functional, integrative medicine. Her blogs effervesce with her enthusiasm for her subject matter and convey her genuine warmth and compassion for her patients. She writes in an engaging style while conveying significant and meaningful information about the varied topics she has covered. They are simply fun to read and easy to learn from her wealth of experience.

Dr. Kara’s blogs are current, scientifically sound, and relevant to clinical care. Her case studies and reviews are focused on how to improve clinical thinking and outcomes using a systems biology and functional medicine approach. They are one of my favorite learning tools and I look forward to her insights and interviews monthly!

Sarah Lobisco, NDND, IFM-CP

Dr. Fitzgerald is what you get when you merge a brilliant clinical brain with a powerful loving heart. Her ability to incorporate seemingly disparate details into a mosaic of meaning that can improve patient care is extraordinary. The opportunity to learn from her should never be missed without great reason.

David H. Haase, MDIFM-CP, FABFM, DABIHM, CNS, BCN

Kara and I have co-authored case studies for peer-reviewed articles and textbooks over the years. I love reading her blog, while evidenced-based and geared towards the professional, the casual style makes for fun reading!

Dr. Kara Fitzgerald’s writing style is clear, concise, well-translated from scientific gobbledygook to understandable every language. And most importantly, it’s accurate.

Of the myriad blogs I receive in my inbox, Kara’s is one that I actually read! It’s funny, clinically relevant and smart.

Sara Gottfried, MDNYT Best Selling Author, Clinician

I am a regular reader of Dr Fitzgerald’s blog/newsletter. I read it because it is useful. Dr. Fitzgerald, stimulated by a recent article, looks into the bulk of the literature and synthesizes the relevant takeaways. Dr Fitzgerald is brilliant and always delivers clinical pearls.

Tom Sult, MDIFM Faculty, Author, Clinician

Wading through emails is not an ideal part of my day. For this reason, I’m very particular about who’s information I want coming into my inbox. When I see an email come in from Dr Fitzgerald, I stop what I am doing and I read it fully right then so I don’t miss it. Her content is always interesting, clinically relevant, cutting edge and many times entertaining as well. I only wish one thing: that she’d write more!

Ben Lynch, NDExpert on MTHFR & Epigenetics

Dr. Fitzgerald has her finger on what’s happening in holistic and integrative health and medicine. I love reading her blog! It’s always right on the mark!

I love reading Dr Fitzgerald newsletter! It is both funny and relevant and offers great info for my patients and colleagues.

Dr. Kara Fitzgerald is a clear, brilliant, and insightful clinician. She always seems to unwrap the story of the patient so well, then identifies the pertinent imbalances and together with the patient initiates the therapeutic plan with successful treatment. She is rare in the education and clinical circles. I always learn from her blogs, conversations, case studies, and lectures. She is an outstanding educator and functional medicine physician.

P. Michael Stone, M.D., M.SCertified Functional Medicine Clinician

I am so happy to have found Dr. Fitzgerald, Romilly and Rhonda who all care about my well being. My life has changed for the better and I will continue whatever staff recommends so I can enjoy my family and feel great.
