How can the foods I eat while pregnant affect my mood?

The foods you eat while you're pregnant can influence the delicate hormonal balance that controls your moods and emotions. So it's worth experimenting with different foods (peanut butter cups don't count) to see if small adjustments can help. Sometimes, though, those neurochemical imbalances make deep dips - and it's hard to recover from them. Plus, resist the temptation to treat your anxiety or depression with overeating (looking in the mirror afterward may only make you more depressed).

One tip: Nuts, fruits, and vegetables may help raise serotonin levels.
