Eating your feelings? Sleep on Stress

Researchers from Michigan State University evaluated work related stress and unhealthy food choices.  
"A good night's sleep can serve as a protecting factor between job stress and unhealthy eating in the evening, indicates a new study co-authored by a Michigan State University scholar.
The study, published online in the Journal of Applied Psychology, is one of the first to investigate how psychological experiences at work shape eating behaviors.  
'We found that employees who have a stressful workday tend to bring their negative feelings from the workplace to the dinner table, as manifested in eating more than usual and opting for more junk food instead of healthy food,' said Chu-Hsiang Chang, MSU associate professor of psychology and study co-author."

Exercise and Healthy Habits

In a recent article from The Wall Street Journal  researchers from George Mason University in Virginia looked at interactions between physical activity and socialization in college students.  

The WSJ reports:

"On a given day, students who exercised also tended to participate in more social and achievement activities than on days when they didn’t exercise, the study found, and they engaged in activities that tended to matter to them more.
In addition, exercise on one day predicted positive social activity on the next day, but not achievement activity.
The researchers also found that positive social and achievement activities on one day didn’t predict exercise on the next day.
The results support an approach to treating depression called behavioral activation."

High Fat Diets and Colorectal Cancer

In a recent study featured in Science Daily, "poor diet is associated with 80% of colorectal cancer cases, but the exact pathways by which diet leads to cancer are not known."

Research from the Cleveland Clinic have identified a specific molecular pathway that links high-fat diets and tumor growth in the colon.  

"In the July 6 issue of Stem Cell Reports, the team showed in pre-clinical models that cancer stem cell growth in the colon was enhanced by a high-fat, Western diet. Cancer stem cells are a subset of resilient, aggressive malignant cells that are believed to be partially responsible for spread and recurrence of cancer.
Furthermore, when the researchers blocked the JAK2-STAT3 cellular signaling pathway, a widely studied pathway known to promote tumor growth, the spike in cancer stem cell growth caused by the high-fat diet declined.
This study provides more insight into how the JAK2-STAT3 pathway is linked to diet-related cancer. Pinpointing the exact mechanism can help researchers develop therapeutics to counteract the negative effects of a Western diet on colorectal cancer" (Science Daily).

Nutrition News Bytes from Around the Web

Research Links for the week:

  • Rethinking nutrition labeling: Food is not just the sum of its nutrients.  Summary:  The nutritional value of a food should be evaluated on the basis of the foodstuff as a whole, and not as an effect of the individual nutrients. This is the conclusion of an international expert panel of epidemiologists, physicians, food and nutrition scientists. Their conclusion reshapes our understanding of the importance of nutrients and their interaction.

  • Vitamin D supplements could improve fertility. Summary: There is new data on the link between vitamin D and male fertility. The new results add to our understanding of the effects of low vitamin D levels on testosterone levels and whether vitamin D supplementation could help improve fertility in both sexes.

  • Fitness trackers accurately measure heart rate but not calories burned, study finds.  Summary:  An evaluation of seven devices in a diverse group of 60 volunteers showed that six of the devices measured heart rate with an error rate of less than 5 percent. The team evaluated the Apple Watch, Basis Peak, Fitbit Surge, Microsoft Band, Mio Alpha 2, PulseOn and the Samsung Gear S2. Some devices were more accurate than others, and factors such as skin color and body mass index affected the measurements.
