Self-control comes in limited quantities, must be replenished

Self-control, whether used to pass up the office cookie plate or to struggle against temptations like alcohol and tobacco, operates like a renewable energy source rather than a learned skill or an analytical thought process, according to new research.
Individuals had less physical stamina and impulse control and increased difficulty with problem-solving activities after completing a variety of tasks that required some measure of self-control, according to Roy F. Baumeister, Ph.D., of Florida State University.

Health benefits of moderate drinking may not apply to African Americans

The widely reported health benefits of drinking a moderate amount of alcohol do not extend to African-Americans, according to a new study. These findings follow a widely reported Jan. 9 New England Journal of Medicine article saying that moderate daily or near-daily alcohol consumption could decrease a man’s risk of heart disease. The researchers in the new study, published in the January issue of the journal Alcoholism: Clinical and Experimental Research, suggest that the difference in protective benefits of alcohol for black men could also be a result of not how much people drink but how they do it.

Study: 15 percent of pregnant women drink alcohol

Despite widespread warnings about the potential risk of drinking alcohol during pregnancy, fifteen percent of pregnant women in a newly published study said they had drunk alcohol at least once during their pregnancies. And although most of those women reported on an anonymous survey that they’d had less than one drink a week, some acknowledged drinking more than that on a regular basis, or said they’d had at least one binge of five or more drinks at once.
