Food should not be a source of stress, rather one of your stress-reducing tools. A healthy and balanced diet will do your body good on the stress scale, but according to this article in MedBroadcast, there are some specific things you should look at adding to your diet that can help ease tension, such as healthy fats.
If you trim the fat during lean times, you leave yourself vulnerable and ill-equipped to handle stress. Healthy fats help support your body with a steadier attitude toward stress; monounsaturated fats, found in peanuts, are healthy fats that can help. Try introducing peanuts into breakfast with recipes such as this Double Peanut Granola, or these Fruit and Oatmeal Breakfast Bars and start the day on the right foot.
