Skeptical that sitting down to a green salad is an answer to calm unsettled nerves? Consider this – there is a correlation between healthy eating and stress management. We are better able to handle stress when we get a decent amount of sleep, eat a balanced diet, and when we participate in regular physical activity.
Elizabeth Anne Scott, a wellness coach, and author of 8 Keys to Stress Management, has some tips. Among them:
Carry a Snack – Having some protein-rich, healthful snacks in your car, office, or purse can help you avoid blood sugar level dips and accompanying mood swings and fatigue. 
Trail mix, granola bars, and certain energy bars all contain good nutrition. Along these lines, you should always have water handy, as it’s so vital to health and proper physical functioning.
Healthy Munches – If you find that you absently munch when you’re stressed, or have a pattern of snacking at certain times in the day or week, you can replace chips, cheese puffs and other less-healthy munchies with carrot sticks, edamame, celery sticks, sunflower seeds or other more healthy choices. (Even popcorn is a better choice if you leave off the butter and salt!)
No Caffeine After 2pm – Since caffeine has a half-life in your body of at least 6 hours, caffeine you ingest with dinner can interfere with your sleep at night.
