"You Have 5 Years Left." She Proved Them Wrong - Twice! with Leslie Kenny

from BETTER! Building bodies women can trust with Dr. Stephanie Estima · host Dr. Stephanie Estima, Leslie Kenny

Leslie Kenny was told in her 30s that she had five years to live. Diagnosed simultaneously with lupus, rheumatoid arthritis, and Hashimoto’s thyroiditis — and told to give up her dream of having children — she did what true Betties do: she refused the prognosis, threw everything she had at it, and got to work. Now 60 years old, Leslie reports a biological age of 21. She is autoimmune disease-free. And she naturally conceived a child at 43. Her recovery journey led her to collaborate with University of Oxford scientists and to discover spermidine — a naturally occurring, food-derived longevity compound that was hiding in plain sight. It’s been in our food for millennia, it’s in breast milk, and it’s in every plant on earth. And it addresses 9 of the 12 hallmarks of ageing identified by science as the root causes of why we get older.

What if signs of aging—grey hair, brittle nails, and skin changes—are actually cellular signals we can address? Leslie Kenny went from an autoimmune diagnosis in her 30s and a five-year prognosis to being 60, autoimmune-disease-free, and giving birth at 43. Her search led her to Oxford scientists and spermidine, a food-derived longevity compound that activates autophagy and targets nine of the twelve hallmarks of aging.
