It has been confirmed that people who consume an adequate amount of whole grains every day have a lower risk of developing heart disease. In addition, whole grains can help protect you from obesity and diabetes. Adequate hydration is essential to a healthy lifestyle. Staying hydrated is important since our bodies are comprised primarily of water. You daily water intake goal should be a minimum of eight glasses.

Help to treat seasonal affective disorder in the winter months. Many of us find ourselves feeling a little down during the cold, dark winter months, but eating certain foods can help to improve our mood. Eat at least four cups of fruits and vegetables per day, and concentrate on whole grains. This will help to raise serotonin levels. Omega-3 fatty acids, found in certain fish, olive oil and flaxseed, can help to enhance your mood. If possible avoid all forms of caffeine, as this decreases serotonin levels.
