Diet has a measurable and proven impact on health and longevity


Americans live with an anxiety disorder, making it the most common psychiatric disorder


increase in risk of developing an anxiety disorder for those who eat a Western diet full of processed foods


reduced risk of developing Alzheimer's for those with a higher Mediterranean diet score


of people treated for anxiety with medication or psychotherapy still experience symptoms

Two founders on a mission to redefine what it means to eat well.

Chaya originated from Katia's own journey during COVID. With her anxiety worsening, she was trying everything from speaking with an anxiety coach to downloading all the different meditation apps, mindfulness apps, fitness apps… the list goes on! She grew frustrated by the disjointed and impersonal wellness ecosystem and wanted a solution that provided a more holistic approach to her health.


Fast forward a few months to when Katia and Christina met in business school. Christina identified with many of the issues present in Katia's own journey, and together they set out to solve this broken narrative surrounding wellness.


It was through their nutrition course that they then uncovered the science behind food as medicine and nutritional psychology. They realized that nutrition is the core foundation needed to achieve all other aspects of wellbeing. Without a solid nutrition baseline, mood and mental health take a serious hit... not to mention the predisposition to disease it exposes us to. 


Katia & Christina were shocked by how most consumer offerings focused solely on weight loss and fad diets, but not on eating to be well. What's more, the information was inaccessible to the general public - you have to invest in prohibitively expensive classes or private sessions to get personalized and credible information on nutrition. Now, these two kickass founders are on a mission to make this crucial information accessible to everyone through Chaya's offerings.
