The watchword is balance:
- One cup of coffee in the morning is a pleasant push into alertness. Seven cups of coffee a day can make your hands shake.
- One alcohol drink is generally a safe way to relax. Three may be a disaster.
- A grilled chicken breast (white meat, no skin) for breakfast on a day when you have to be on your toes before lunch can help make you sharp as a tack.
- Got an important lunch meeting? Order starches without fats or oils: pasta with fresh tomatoes and basil, no oil, no cheese; rice with veggies; rice with fruit. Your aim is to get the calming carbs without the high-fat food that slows thinking and makes you feel sleepy.
