Fatty foods can hinder your mental alertness, says study

Scientists have shown that consuming fatty foods can affect alertness and result in fatigue, says a study. Results show that higher fat consumption is associated with increased objective daytime sleepiness, while higher carbohydrate intake is associated with increased alertness. There is no relationship between protein consumption and sleepiness or alertness. These findings are independent of the subjects’ gender, age, and body mass index as well as the total amount of sleep they are getting and their total caloric intake, reports Science Daily. ‘Increased fat consumption has an acute adverse effect on alertness of otherwise healthy, non-obese adults,’ said principal investigator Alexandros Vgontzas, professor of psychiatry at the Penn State College of Medicine in Hershey, US. ‘Excessive daytime sleepiness and fatigue are on the rise,’ said Vgontzas, adding that ‘this might impact on an individual’s ability to function and also public safety.’
