Now, to be clear, I'm not saying that people should use food to medicate their depression. Many people do that reflexively however, they reach for carbohydrate rich foods to blunt their cortisol, because that's indeed what it does. It blunts cortisol when you ingest high carbohydrate foods, in particular starchy foods, and it does increase serotonin, in particular, if those foods rather are rich in the amino acid tryptophan.
