Gut Health 101 with Katie Kirklin

Alison welcomes Katie Kirklin, a registered nurse and certified functional nutrition counselor who is also training in nervous system regulation. The discussion focuses on digestive health and gut health, with an emphasis on both the science behind the topic and practical steps listeners can apply.Katie shares her personal health history and describes developing health problems in her teens and 20s, trying different diets and medications, and feeling that standard approaches did not address underlying causes.She then explains a major turning point in 2020 when an abnormal Pap smear and biopsy showed moderate cervical lesions. After choosing to make diet and lifestyle changes and working with a naturopath, she later received clear results, which led her to learn about functional nutrition and the idea of addressing root causes rather than isolated symptoms.The discussion moves to gut health and Katie explains that gut health affects nutrient absorption, the microbiome, and the gut lining. She describes leaky gut as increased permeability in the gut lining, which can allow proteins and pathogens into the bloodstream and contribute to inflammation.Katie identifies common inflammatory factors, including highly processed seed oils, ultra-processed foods, processed sugar, gluten for some people, and dairy for some people. She recommends reading ingredient lists rather than front labels and gradually increasing whole foods to crowd out processed foods.Alison and Katie also discuss the importance of individualized nutrition and reintroduction after elimination, since the gut microbiome benefits from diversity. Katie emphasizes that different people can respond differently to the same foods.They also cover the gut-brain connection. Katie describes the vagus nerve as a two-way communication pathway between the brain and gut and notes that most of the body’s serotonin is produced in the gut. She says these connections help explain why digestion, mood, sleep, and overall health are linked.In her client work, Katie starts with blood sugar balance, sleep, digestion, hydration, movement, and fiber intake. She recommends tracking food, symptoms, and bowel movements, and suggests beginning with a nourishing whole-food breakfast to support stable energy and better choices throughout the day.HIGHLIGHTS:4:03 Functional Nutrition Journey7:29 What Gut Health Means10:47 Gut Inflammation Triggers14:58 Understanding Leaky Gut18:59 Body Systems Connected27:43 Start With Breakfastconnect with Katiewebsite: https://www.katiekirklin.comSPONSOR:Cellev8Discount code: THEALISONK ALISON'S LINKS:Website | Facebook | Twitter | InstagramGET MY FREE 4 part Pop-up Podcast SeriesJOIN Borderless Hybrid Innovators FB GroupINNOVATION AVENUE: Fitness and Self-Care Revolution
