11 Jun 2019 --- Large numbers of adults and teenagers in the UK are falling short on the recommended number of hours of sleep for their age-group, despite emerging research linking poor sleep quality to less healthy food choices and increased risk of obesity. This is according to British Nutrition Foundation (BNF) research, which reveals that 43 percent of adults reported sleeping less than the recommended minimum of seven hours on the previous night, and that 32 percent of primary and 70 percent of secondary school children reported sleeping less than 9 hours on the previous night.
