Research from America’s Brigham Young University tracked data from nearly 20,000 employees and found that a poor diet can have a big impact on ‘presenteeism’ – where workers are present, but not completely productive at work – as well as absenteeism.
The employees with an unhealthy diet were 66% more likely to report having a loss in productivity as opposed to healthy eaters.
The employees who ate five or more servings of fruit and vegetables at least four times a week were 20% more likely to be productive during their working day.
In contrast, those who rarely ate fruits, vegetables and low-fat foods at work were 93% more likely to report a loss in productivity.
Meanwhile, absenteeism was 27% lower in staff who ate a healthy diet and also regularly exercised.
