No, it's not a weird form of PMS, it's psycho-neuro-endo-immunology, and everybody is talking about it. It's the branch of science that examines the impact of psychological factors on the nervous, hormonal and immune systems -- in other words, how stress affects our minds and bodies. Stress, of course, is fashionable right now, and the latest PNEI findings maintain that diet can play a significant part in improving your emotional and physical wellbeing.
If you think about it, we all "self-medicate" during stressful times -- upping caffeine intake to keep wired, stuffing in the sugar for comfort or quaffing wine to calm down. Eating lentils will not solve financial worries, stop the baby crying or repair a broken relationship, but making careful food choices in moments of strength can help your body through times of strife.
