Eat fruit daily: Fruit offers a great source of antioxidants, which may help prevent cancer, cardiovascular disease, Alzheimer's disease and macular degeneration. The berry family — blueberries, blackberries, raspberries, strawberries and cranberries — are good sources of antioxidants. So are cherries, oranges, and prunes.
Make high-fiber foods a staple: Whole grains, beans, fruits and vegetables are good sources, as is cereal with psyllium, which may help reduce low-density lipoprotein (LDL), also known as "bad'' cholesterol.
Take a brisk walk: Brisk walking improves cardiovascular and bone health. Try to walk at least 30 minutes a day at a moderately intense level.
Make stretching and strength building a habit: Regular stretching and strengthening can enhance mobility and help prevent falls.
Pursue yoga and tai chi: These gentle mind-body practices combine five important types of exercise — aerobic, strength training, core stability, flexibility and balance. Research suggests they help reduce blood pressure, reduce stress and improve mood and sleep.
Be optimistic: Research indicates that positive thinkers are more likely to feel better and live longer.
Develop an attitude of gratitude: Be thankful for every experience — good and bad — and recognize each is an opportunity to learn and grow.
Try volunteering: Research shows meaningful volunteer activities promote emotional and mental well-being.
Enjoy a pet: A small but growing body of research suggests pet ownership benefits health in several ways. One study found that among those who had a heart attack, dog owners were significantly more likely to be alive a year later than were those without a dog. Dog owners benefit from regularly walking Fido, too. They are less likely to be obese than non-dog owners.
Improve relationships: Take conscious steps to forgive those closest to you — and yourself. Forgiveness is associated with improved mood and lower stress.
