Animal-based protein diets increase mortality rate

Not all proteins are equal when it comes to the health of dieters eating low-carbohydrate, high-protein diets.

Animal-based proteins and fats are associated with increased mortality rates, including increased cardiovascular mortality and increased cancer mortality, a new study published in the Annals of Internal Medicine concludes. But low-carbohydrate, high-protein diets composed mostly of plant-based proteins and fats were associated with lower mortality rates overall and lower cardiovascular mortality rates.

Study: Lack of sleep for babies and toddlers may increase obesity risk

Babies and children under the age of 5 getting less than 10 hours of sleep at night are more likely to be overweight or obese five years later, a new study suggests.

Researchers found that insufficient sleep at night may be a lasting risk factor for obesity later in life and that napping cannot replace the benefits of nighttime sleep," according to a study published Monday in the journal Archives of Pediatrics & Adolescent Medicine.

"This is something we may be able to change to address the growing obesity problem," said study author Dr. Janice Bell from the University of Washington.

Don't dismiss dads' depression, researchers urge

Bringing home baby can lead to depression in as many as one-fifth of fathers during the first year of the baby's life, according to a study published Monday in the Archives of Pediatric & Adolescent Medicine.

While the new study echoed the well-documented notion that mothers have a greater likelihood of developing postpartum depression than men due to hormonal changes during pregnancy, researchers warn against dismissing the risk for fathers.

More on money (not) buying happiness

You may have seen our coverage of a recent study showing that most people with a household income of $75,000 per year are happy, but that happiness doesn't appear to increase with incomes higher than that.

A newer study in Proceedings of the National Academy of Sciences backs that up when it comes to everyday happiness - but not when people were asked to think about their overall satisfaction with life.

Could 'runner's high' chemical help curb overeating?

As a primary care internist, my practice spans the common adult ailments—diabetes, hypertension, high cholesterol, coronary artery disease, arthritis. It is hard not to avoid the difficult truth that obesity, while perhaps not causing all of these illness, certainly exacerbates them greatly.

With my patients, I stay away from issues of blame—it’s a pointless endeavor and causes unwarranted guilt and shame—but obesity is a critical medical issue that cannot be ignored just because it is difficult to treat.

I've always been a bit leery of medications and surgery to “treat” obesity, partly because of their limited efficacy but also because rethinking the way we eat—in the long term—is a cornerstone of good health.

Nevertheless, despite my ongoing discussions about five servings of fruits and vegetables, avoiding soda and fast food, etc, I’ve come to accept that other “treatments” have a role in treatment for at least some patients.
