What we eat has a big impact on our performance at work – from mental clarity, to energy, stamina and productivity, food governs how well our bodies and brains function. Food makes our mood. Yet food at work is too often seen as a financial afterthought by employers and is a missed opportunity to increase productivity and morale. Staff restaurants typically offer unhealthy selections while vending machines are stocked with sugary and fatty snacks. Employers’ workplace programmes focus on wellness – getting people fitter – and how healthy employers take less time off work. But ensuring your employees are eating the right foods is about increasing presenteeism — employees being fully engaged, energised and mentally focused on the task in hand.
