Yup changing my diet has helped a lot. I'm not sure if it directly effects my mental state but maybe indirectly. Like my body is functioning better so my mental state feels improved. I'm not gluten free/dairy but very gluten/dairy limited. Cutting out pasta and bread for the most part. I only eat dairy occassonally when it is an ingrediant within something. But no milk, icecream etc. Cafeine elimination and preservative elimination has been the most helpful. also cutting down on added sugars.
It also helped to be paying attention to when, how much and how often I was eating. Keeping my metabolism from going up and dramatically during the day has worked wonders. So remember to eat a little and often.
