A diet high in carbohydrate was shown to reduce cortisol and negative mood after stress [63], and carbohydrate loading was shown to increase performance and inhibit the typical cortisol increase in response to prolonged exercise [64].
“Eating foods such as processed meats, high sugar foods, caffeine and alcohol, which provide little nutritional value, have been associated with more psychiatric symptoms and can increase cortisol levels—our primary hormone responsible for stress,” she said.

If you skip a meal your body sees this as a small emergency. As a result your cortisol levels will rise. When cortisol levels are elevated it causes fat to be deposited deep in the abdomen. This visceral fat in turn will produce more cortisol so that losing it becomes quite challenging.
For humans, cortisol begins to increase immediately after fasting commenced (Fig. 1C) [78]. Five-day fasting increases cortisol levels and shifts the peak from the morning to the afternoon [79]. Other fasting experiments for 2.5 to 6 days dramatically elevates plasma cortisol levels [80–82].
Not only can bananas provide a great source of energy, but research showsTrusted Source they can also reduce inflammation and oxidative stress levels that are associated with increased cortisol.

As the body's primary stress hormone, cortisol surges when we perceive danger, and causes all the symptoms we associate with “fight or flight”—increased blood pressure and heart rate, muscle tension, and the digestive system slamming to a halt, resulting in nausea, vomiting, and diarrhea.
