Bay Area Functional and Integrative Health

About Joan Lu, PhD, RN, PHN, BC-FMP Joan Lu is a California Registered Nurse, Board-Certified Functional Medicine Practitioner, and Culinary Medicine Educator focused on healthy aging and whole-person care. Throughout her nursing career, she has focused on chronic disease management, helping patients navigate complex health conditions, polypharmacy, and challenges affecting their quality of life. Her passion for functional and culinary medicine is also personal. Like many women, Joan has experienced her own health challenges, including PCOS and endometriosis. These experiences inspired her to look beyond symptoms, look for the root causes and better understand the role of nutrition, lifestyle, and metabolic health. Today, she combines conventional, functional, integrative, and culinary medicine to empower individuals through education and informed health decisions. Her philosophy is simple: Healthy aging isn’t just about living longer, it’s about living better. At Bay Area Functional & Integrative Health, we support healthy aging through health education and personalized support to help you live a better quality of life, no matter your age.
