Association of Sleep Deprivation, Gut Microbiota and Diet in Obesity
We have read the nice article News and Views by Ms. Renugasundari (IJCEP Vol 6, Issue (3), Jul-Sep, 2019 page 104) about sleep deprivation and obesity. Smith and colleagues have observed that there is an association between sleep and gut microbiome diversity. The microbiome composition observed by them shows that within phyla richness of Bacteroidetes and Firmicutes were positively correlated with sleep efficiency and abstract thinking. Several taxa (Lachnospiraceae, Corynebacterium & Blautia) were negatively correlated with sleep measures. Haro and colleagues suggested that gut microbiota may be different in men and women and that these differences may be influenced by the grade of obesity. Cao and colleagues have studied more than 62 thousand children aged 6 to 17 years in China and they observed that short sleep duration was associated with increased risks of more sugar beverage intake and less vegetable and fruit intake. Bhutani and colleagues have found that sleep deprived participants changed their food choices and they ate food with higher energy density (more calories per gram like doughnuts, chocolate chip cookies & potato chips).
