Good information. Starchy foods at dinner, sweet treats after dinner was a bad habit for me. Anything white not good for you. White bread, noodles, rice, bread, potatoes etc they all turn to sugar and spike your insulin then your mood.

I find that the foods I crave and eat depend upon my mood / depression. This is usually my first indication that things are sliding. (more 'bad' foods in excess of what is my normal = depression). When I eat sugar or bread then I too get tired more, but I believe it is more of a metabolic process of the liver and digestion than other issues.

Yes what I eat affects my mood, no white sugar for me or corn syrup added to my food.
