Eat A Helthy Diet For The Right Reasons: Rather than eating right for the promise of looking better in your jeans, you should make a commitment to eating foods that will boost your energy level and keep your system running smoothly. This is because what you eat can not only impact your short-term and long-term health, it can affect your stress levels. If you're hungry ur malnourished, you may be more emotionally reactive to stressors, or may not have the reserves to handle what comes up as efficiently as you would if you were operating on a full stomach of healthy food. Watching what you eat can be a stress management tool as well as a health preserver.
