This week, Wal-Mart announced the release of its home-grown, front-of-pack nutrition guidance system. Can we possibly be that gullible? If so, we probably all deserve to be eating whatever the big companies selling food tell us we should.

It's a dark day in the life of a healthy food maven when you can't meet a cruciferous vegetable request from a child or loved one.

Here we are at Day 10 of 29 days of American Heart Month blogs. I would be remiss in not reviewing what you want to know about your heart health numbers.

Have you noticed the number of companies that are no longer promising the best quality, experience or even the best price for a product or service as the reason to give them a try? Instead they appear to be offering something we used to think money couldn't buy -- happiness.

On this, the 12th annual National Black HIV/AIDS Awareness Day, I remember my sister-in-law's fight with the disease. It is in her memory, and the memory of all the friends and loved ones we have lost, that we vow to keep working toward the day when HIV/AIDS is history.

After sitting a few minutes in the waiting room I was asked to meet the doctor in his office. He stood up, smiled (oh God, why is he smiling?) and proceeded to close the door (oh God, why is he closing the door?").

The logical thing to do as part of our pain management transformation is to make weight management an inherent part of pain education, treatment and prevention.

With Valentine's Day fast approaching and our youngest daughter's first birthday coming even sooner, we're in the mood for sweet treats in Rome. But here's what we'd like to avoid: a giant family-wide sugar crash.

Learning is an ongoing process that doesn't end with old age. Learning anything requires discipline, practice, humility and hard work. It's intensely rewarding, and the process is invigorating.

The American Psychiatric Association plans to release the newest edition of America's psychiatric bible, the DSM, in 2013. The effort to determine what constitutes normal and abnormal behavior in America is apparently an ongoing process.

When it comes to expressing the truth in our heart, love cannot be commissioned. Love cannot be purchased. Love must have an open space, a safe place in which to land, tell its truth, and have room to breathe without demands or the need for defense.

What's actually going on in the mind of an alcoholic as he or she goes through the process of recovery? What are the cognitive mechanics underlying the initial, angry rebelliousness and, later, the genuine commitment to a sober life?

As a therapist specializing in eating issues, I'm all too aware of the pervasive cultural pressures to be perfectly thin. So when I heard Katharine McPhee would be stacked up on the little screen against America's biggest sex symbol, I couldn't help but wonder how she's handling those pressures.

Writer, The Happiness Project

As a result of my happiness project, I've become a sleep zealot. It's just so obvious to me -- from reading the research and from personal experience -- that getting enough sleep is a key to a happier life. I've noticed something, however: Most adults don't give themselves a bedtime.
