Especially As We Age

1 Aerobic Exercise Boosts Brain Function

Aerobic exercise boosts brain function as we age, finds a study that showed that fitter older individuals scored better on mental tests than older individuals who are unfit. Researchers found that study participants who were assigned to an aerobics program had improved cognitive function compared to those assigned to stretch and tone classes. Furthermore, while the results were not replicated in young adults and children to the same degree, researchers found that involvement in aerobics activity boosted memory and the volume of information stored in the brain across all age groups prompting them to conclude that engaging in a program of regular exercise is a simple way to boost brain function. The review is published online in Psychonomic Bulletin and Review.

Got Milk?

2 Two Cups of Milk Per Day Optimal for Kids

Many parents ask their child’s doctor how much milk they should be giving to their kids. Answers were vague; recommendations were unclear. Now, new research sheds light on this age-old question and finds that two cups of cow’s milk per day maintains adequate levels of vitamin D and iron for most children. Researchers from St. Michael’s Hospital used questionnaires and blood tests to learn how cow’s milk affected those two nutrients in more than 1,300 children, ages 2 to 5. They found that more than two cups of milk per day reduced iron stores and offered no additional vitamin D benefits. They also suggest wintertime vitamin D supplementation vs consuming more milk to increase levels. The Canadian Pediatric Society does not recommend cow’s milk for children less than one year of age.

Speed Bump Positive Is Negative

3 Pain over Speed Bumps Clue to Appendicitis

Patients who experience pain when traveling over speed bumps on their way to the hospital for abdominal pain are more likely to have acute appendicitis, say researchers. Published in the BMJ Christmas issue, the new study found an increased likelihood of a patient suffering from appendicitis if they were "speed bump positive." Patients who are classified as "speed bump positive" had worsening pain while traveling over speed bumps, and patients whose pain stayed the same were classed as "speed bump negative." While being "speed bump positive" doesn't guarantee a diagnosis of appendicitis, researchers believe that doctors should routinely ask about pain associated with speed bumps.

Hair Before Health

4 Hair Makes Black Women Avoid Exercise

Results of a new study suggest that some Black women avoid exercise because they want to mess up their hair. One hundred and three Black women who came to the Wake Forest University dermatology clinic took a survey about exercise. Over 50 percent exercised less than 75 minutes a week, less than the recommended 150 minutes by the U.S. Department of Health and Human Services. About 33 percent of the women surveyed said their hair was a reason they did not exercise and half thought about changing it so they could. An itchy scalp and dandruff were also factors. Hair care for Black women is laborious and costly, and many avoid sweating so they only have to wash their hair weekly to keep their style.
