I'm Scarleth Castro, Nutrition and Health Promotion Educator  & Owner of SYOA Nutrition Services & Educational Platform.

One of the biggest things in my life is education. I believe that power is knowledge. The more we know; the better we can live, the healthier we can live, and the longer we can live.

This is why through SYOA I have created my nutrition coaching and a platform centered around education, support and empowerment to help you make well informed, positive and important health decisions, create healthier habits and become a badass in the kitchen!

As a Nutritionist, Health Promotion & Nutrition Educator, I am very passionate about hormones in women and men's health, the connection it has via food and the behavioral change aspects in nutrition.

My mission is to connect education, improve health via food and   behavioral changes to help you build longevity.

In this space you will be able to enjoy science-based articles surrounding topics of nutrition and health (written for everyone to understand and removing the complexity of science lingo to make it easy to ingest).

Together with offering a mix of recipes, lifestyle management and personal development tools to help you create your journey to a sustainable life and build longevity.

I am currently completing a Master’s degree in Exercise Science, Fitness and Health Promotion with a minor in Nutrition at George Mason University and I am on the road to becoming a RDN in the state of Virginia.
