Restaurant Calorie Counting

One of the requirements as listed by the Patient Protection and Affordable Care Act (2010) asks restaurant chains with 20 or more locations across the U.S. to list calorie information on menus. Major cities across the U.S. have already fulfilled these requirements since 2009. Interestingly, Reuters Health reported today about a cross-sectional analysis (Journal of Public Health) indicating that only 1 in 3 diners actually make use of this information. This study was conducted in just over 4000 adults in the U.S. who ate out at restaurants either multiple times a week or on a monthly basis. Among the diners, women were reported to have higher rates of reading calorie information but no significant changes have been reported in terms of consumers purchasing more lower-calorie options. Seeing as obesity is a large contributor to chronic diseases, controlling portion sizes especially when eating out is quite important. Do you think that calorie-counting makes a big difference in weight management? How you counsel your patients on healthy eating as well as watching their caloric intake?

Energy Drinks Do Alter Heart Function

A study looking at the effect on heart contractility from energy drink consumption was released today via the annual meeting of the Radiological Society of North America (RSNA). Teenagers and young adults have been warned about the risks of consuming drinks high in caffeine and taurine content related to the increased number of ER visits resulting from rapid rises in blood pressure, seizures and even death. Investigators from the University of Bonn, Germany have been studying the effect of the content of these drinks on 18 volunteers aged around 27 years. MRI reports done 1 hour post consumption of drinks high in caffeine and taurine content revealed significant strain on the heart’s ability to contract from the left ventricle.  It is well known that impairment of the heart’s ability to contract appropriately could lead to arrhythmias and even seizures. More studies are needed to determine the long-term impact that energy drinks have on the heart but these short-term findings are nothing short of concerning. Do you counsel your patients to watch their caffeine intake and to avoid unnecessary consumption of energy drinks? Do you think we need tighter regulations on energy drinks?

The poll, including responses from 2,000 teenagers between ages 12-18, observed some concerning breakfast habits. Teens would either skip breakfast or choose food items very high in fat, sugar, and caffeine– energy drinks being a popular choice. A frequently consumed “shot style” energy drink contains 175mg of caffeine! Not only does eating in this manner become hazardous to their health, it also negatively impacts their behavior and academic performance as well.

Soft drinks consumption is associated with behavior problems in 5-year-olds.

149275_of404-mSoft drink consumption has been in the news a number of times during this summer.  Here is another prospective birth cohort study that was recently published in the Journal of Pediatrics.  Researchers followed 3,000 5-year-old children and their mothers from 20 large U.S. cities. Every two months, each mother had to report their child’s soft drink consumption then complete a checklist to assess their child’s behavior. Scientists discovered that children who consumed soft drinks had increased aggression, attention problems and withdrawal behavior as opposed to those who did not. Furthermore, children who drank 4 or more soft drinks per day were more than twice as likely to destroy things belonging to others, get into fights, and physically attack people. Does your library of evidence related to soft drink consumption help you to persuade your patients and their parents to eliminate them from the diet? What practical tips do you offer in substituting soft drinks for something more healthful?
