Deanna Minich, PhD

I am a nutrition scientist, functional medicine expert, educator, and thought leader with more than 25 years of experience bridging science, clinical practice, and lifestyle medicine. I serve as Chief Science Officer at Symphony Natural Health, where I guide scientific strategy and innovation in women’s health and healthy aging.

My work is rooted in an integrative Food & Spirit philosophy and my pioneering approach to color-coded nutrition, known as the Rainbow Diet. This framework connects the phytonutrients in foods with whole-person health across physical, emotional, and energetic dimensions. My areas of focus include hormone health, perimenopause and menopause, mitochondrial function, circadian biology, detoxification, and personalized lifestyle medicine.

A central part of my work explores the intersection of biology, light, energy, and consciousness. Through my Science & Spirituality Talks YouTube channel and educational programs, I examine how emerging research in areas such as circadian rhythms, bioenergetics, and mind-body science connects with timeless principles of awareness, meaning, and human potential.

I am the author of several books, including The Rainbow Diet and Whole Detox, and I teach healthcare professionals and the public around the world. My passion is translating emerging research into practical, sustainable strategies that support metabolic, brain, and endocrine health across the lifespan.

Through my writing, speaking, and teaching, I help people understand that health is not just about nutrients or lab values. It is about living in alignment with the rhythms of nature, the biology of the body, and the deeper connections between food, light, energy, lifestyle, and purpose.
