Barley Compounds May Help Weight Management Goals

Posted May 04 2013 10:08pm

Previously, animal models suggest that gut microbial metabolism may affect host metabolism, including appetite regulating hormones.   Elin V Johansson, from Lund University (Sweden), and colleagues evaluated the potential effects of a whole grain barley kernel product, rich in intrinsic indigestible carbohydrates (dietary fiber and resistant starch), on markers of metabolism and appetite regulation in healthy men and women. The team enrolled 19 young adults, each of whom was randomly assigned to consume late evening meals with additional boiled barley kernels, or white wheat bread.  Blood samples were collected during the following breakfast and lunch times.  The barley kernels associated with an increase in glucagon-like-peptide-1 (GLP-1), a satiety hormone, as compared to white bread. Further, the group consuming the barley kernels experienced a decrease in free fatty acid levels and reduced inflammatory markers.  The team also observed a significant reduction in energy intake during lunch the next day among the barley consumers, as compared to the white bread group.   The study authors conclude that: “The results indicate that the [barley kernel]  evening meal, facilitate glucose regulation, increase the release of GLP-1, reduce subsequent energy intake while at the same time decreasing hunger over 2 subsequent meals, and fasting ;free fatty acids] the subsequent morning, possibly mediated through gut microbial fermentation of the indigestible carbohydrates.”

Tip #156 - Social Ties May Slow Memory Decline
Staying connected with family and friends can beneficially impact memory as we age. Harvard School of Public Health (Massachusetts, USA) researchers studied 16,638 men and women, ages 50 and over, to assess the impact of social integration on changes in memory during a six-year period. The team found that the study participants with high social integration at the start of the study encountered slower rates of memory decline over time, as compared to the less socially integrated subjects. Memory among the least socially integrated declined at twice the rate as that of the most socially integrated.

Among men, social activity in midlife may slash the risk of dementia. Researchers from Johns Hopkins Bloomberg School of Public Health (Maryland, USA) studied 147 male twin pairs for 28 years. Among the twins, those who participated in social activities at home, visited with family and friends, and engaged in club activities and hobbies were less apt to develop dementia.

Be sure to stay in-touch with loved ones on a regular basis. Your network of family and friends not only provides moral support and encouragement, it might also help delay a declining memory.
