Odds & Ends from the Journals
- Katherine
Tallmadge, author of Diet Simple suggests that eating
a big breakfast is the best way to get multiple servings of grains,
fibers and vegetables. A big breakfast also tends to make you
less hungry during the day and less likely to make a beeline
for a Value Meal at lunchtime.

a Registered Dietitian with whom you can network or consult? Check out
the American Dietetic Association’s web site, where you can locate
an RD near you. Visit: www.eatright.org
- The Journal
of Sexual Medicine finds that belonging to a warm and fuzzy
support group wards off depression for women, but not for men. This
may be an important consideration when designing group or individualized
raining programs for your female clients: for a buddy group to
improve morale, motivation and adherence.
- The Journal
of the National Cancer Institute has identified 17 new cancer-causing
agents, to join the list of “old faithfuls” like asbestos,
cigarettes, radon gas and excess alcohol. Some of the new cancer-causing
agents include chemicals found in mothballs, toilet cleaners,
ink and paint as well as the viruses that cause Hepatitis B
& C. Chemicals found in cooked meat and eggs were also implicated.
- The Journal
of the American Geriatric Society reports that elderly people
whose spouse is their prime caregiver have the highest risk
of abusive treatment.
- The New
England Journal of Medicine reports that any sudden emotional
shock can trigger a release of stress hormones up to 30 times
higher than normal levels, and two to three times greater than
the levels seen during a heart attack. This sudden shock can result
in serious an long term health problems; researchers are calling this
“broken-heart syndrome.”
- As reported by Columbia University’s www.goaskalice.com male clients who train for endurance have lower levels of serum testosterone than their counterparts who engage in weight lifting. Researchers speculate that the higher testosterone levels are in response to muscular overload.
Disordered Eating
Affects Bone Density Analysis
Few studies have looked at the entire “female athlete triad” of disordered eating, menstrual irregularity, and bone mineral density in its entirety. This study correlates each component to the others both individually and as part of a complex interrelationship.
Ninety-one competitive long-distance college and post-collegiate female runners (ages 18-25) were questioned on menstrual irregularity, diet, and eating behaviors (the Eating Disorder Inventory (EDI). They were also evaluated based on Body Mass Index (BMI) and bone mineral density (BMD). The relationships between amenorrhea, training, diet, and physical characteristics were analyzed.
As expected, women with elevated EDI scores ate fewer calories, especially fat calories, than the low scorers. They were more likely to have amenorrhea, had a greater “drive for thinness” and tended to run more miles per week than those with lower EDI scores. Surprisingly, those with higher EDI scores were slightly fatter and weighed MORE than the low scorers did. Interestingly, despite expectations of a greater BMD due to a heavier weight, the elevated EDI scorers had significantly lower BMD than the normal scorers.
The conclusions? Disordered eating is correlated with menstrual irregularities; there is a relationship between menstrual irregularities and BMD regardless of actual body weight or body composition. Finally, disordered eating is associated with low BMD. A final note: the women in this study were not necessarily lean women; they averaged 22-25% fat. This may make identification of those with the triad more difficult.
