It is fascinating how food can contribute to disease but also how food can heal. How the body responds to food is why I, On Ki ? Kim? Chan, MS, RDN, became a Registered Dietitian Nutritionist. It was after having kids with behaviour and digestive issues that I became passionate about functional nutrition and getting to the root cause(s), not only managing symptoms. Because of my kids and overcoming my health issues with digestion, I do what I do today-help others with digestion and gut health (i.e., SIBO, gas/bloating/constipation/diarrhea, acid reflux, IBS, Crohn’s, ulcerative colitis, dysbiosis, intestinal permeability or ? leaky gut?), women’s health and hormone issues (PCOS, perimenopause/menopause), chronic diseases (hypertension, high cholesterol, high triglycerides, high LDL, fatty liver, metabolic disease, type 2 diabetes, pre-diabetes), weight issues, heart health, autoimmune disease, prevention of disease, cancer (current or prevention), and longevity. My interest is in digestion/gut health, metabolic health, hormones, and liver health, as I think this is foundational to overall health. I use a food-first, science-based approach. I like to ensure that everyone has a good foundation and then see what else can be done to optimize health. I am a female Asian with a strong Chinese family background who grew up in a diverse culture in Hawaii in a low-income neighbourhood am culturally and socioeconomically sensitive. I feel everyone deserves nutritional care at any age. My education includes a Bachelor of Science degree in Nutritional Science from Pepperdine University and a Master of Science degree in Human Nutrition from the University of New Haven. My past experiences include outpatient clinics:
1) women, infants, and children clinics in a community health setting;
2) maternal, adolescent, and children’s care in an HIV/AIDS/immunology clinic;
3) private pay settings; and 4)
a longevity clinic.
