If you have ever wondered whether food might be affecting your mood, anxiety, or energy, you are not alone. Many of the people I work with reach a point where stress feels heavier than it should, emotions feel harder to regulate, or their body just feels off. They start asking questions like, “Is this just in my head?” or “Could what I am eating actually matter?”

That curiosity often leads people to terms like nutritionist, dietitian, functional nutrition, or functional nutritional therapy. And honestly, it can get confusing fast. The words sound similar, but the approaches are not the same.
