From a dietary standpoint --- I would opt for balanced meals of the following:
very lean protein + low glycemic index carb that is also packing a low glycemic load + omega-3 fish oil (preferably carlsons brand).
That way insulin is never harshly pulsed due to glycemic load (amount of grams per meal) + it wont fall to rapid from the GI being low (fiber content).
Omega-3 has been shown is several studies to be anti-catabolic.
For supplementation -
I would use a phospholipid complex -- phosephatidyl serine, phosphatidyl choline, phosphatidyl ethanolamine, and phosphatidyl inositol found in EndoAMP Max.
Even something with a 7,8 benzoflavone ingredient to increase mild sedation like effects which displays anxiolytic effects.

These are good points, but this stuff won't do much for someone with a real chemical imbalance in brain chemistry who has anxiety or stress.
