Regardless of its source, your body has a very specific physical reaction to stress. Called the "fight or flight response," it is triggered by signals sent from the brain that lead to a surge of stress hormones. These hormones in turn trigger physiological changes, including increased heart rate, rapid breathing, muscular tension, elevated blood sugar levels, and a state of hyper-alertness. That's fine if the situation warrants it, but most of our stress is provoked by events that are not in the least life-threatening.
Diet
To keep your emotions on an even keel, eat foods that provide a sustained release of energy, such as vegetables, fruits, and grains. Lean protein from fish, skinless poultry, nonfat yogurt, and beans and legumes will provide the stamina you need to function at your best. Avoid dietary disasters that have virtually no nutritional value — fatty animal products, refined carbohydrates, hydrogenated fats, and processed oils.

Exercise
If the health benefits of exercise could be put in a pill, you would have perhaps the most powerful anti-aging medicine available. Regular physical activity supports virtually every system in your body, from your bones and muscles to your heart and cardiovascular system. Exercise improves immune function, aids digestion and elimination, increases endurance and energy, and enhances mood.

Nutrients
I consider a comprehensive, high-potency multivitamin and mineral formula to be the single most important step you can take to improve your health. I also recommend DHEA and green tea to help with stress.
