From a professional sceptic on a personal mission

I really don’t just swallow anything! As a documentary-maker and journalist who’s had the privilege of reporting for the BBC and National Geographic TV, I’m the unlikely founder of Karmacist. But I’ve always had a passion for wellness, scientific discovery and mental health—driven by my desire to take the edge off, and understand my own experiences of depression and anxiety.

Digging into this for my podcast All Hail Kale, I came across inspiring Ivy League scientists—and their amazing insights from merging botanics with a fascinating new field of science. Something I felt compelled to share.

Our pioneering professors

Dr Uma is a leading figure in nutritional psychiatry, which explores the impact of nutrition on our mental health. It’s the subject of her bestselling book The Food Mood Connection. She is the director of nutritional and lifestyle psychiatry at Massachusetts General Hospital and on the faculty at Harvard Medical School. Dr Uma has been asked by the American Psychiatric Association to author the first academic text on Nutritional Psychiatry.

She is also a trained professional chef and starts her day with a cup of turmeric-rich golden milk with fresh ginger. “It’s been a tradition I’ve shared with my grandmother since childhood.”

Dr Uma Naidoo, Harvard Medical School

Prof Vittorio runs an eleven-person research lab at the Stanford School of Medicine in California, where he is an Epigeneticist, Stem Cell Biologist and Reproductive Biology expert. He has made several seminal contributions in Regenerative Medicine and has recently discovered a breakthrough approach for the treatment of ageing. Dr Sebastiano has received a number of prestigious awards – and is currently writing a book on genomics and ageing.

“What we’ve just discovered – and is amazing to see – is how changing the expression of certain genes can ‘rejuvenate’ any cell type of the body. This is going to have enormous repercussions for human health.”
