There are various reasons to hamper our work in the office and a recent study has found that eating at the work desk, especially, smelly food is also a major reason.
Having lunch at the desk is now becoming common at work place and two out of five people were too busy to take a proper break for lunch.
In a survey of 1,000 office workers, two out of five said they were too busy to take a proper lunch break, while over half branded colleagues who eat strong-smelling food as 'anti-social'.
Pungent packed lunches include oily fish, cheese and egg sandwiches and these have an adverse effect on working conditions and office culture.
The worst smell was said to be mackerel or sardines, followed by cheese and eggs and the best smelling were buttered toast, fresh pastries and bacon sandwich.
But desktop dining may not only be bad workplace etiquette - it could also have a detrimental effect on waistlines.
Experts have warned that the growing culture of eating in the office could lead to weight gain, with health psychologists saying it distracts people into forgetting they have eaten.
Prof Ogden advised office workers to build a proper lunch break into their schedules and said, "Any form of distraction, including eating at our desks can lead to weight gain."
Eating at one's desk is also highly unhygienic - with computer keyboards and worktop surfaces being riddled with millions of bacteria. In 2014 Dr Lisa Ackerley, Professorial Fellow at the Royal Society of Public Health, warned that the average office worker comes into contact with 10 million bacteria a day.
"We know from studies 3,000 organisms per square inch can be found on a keyboard or over 1,600 a computer mouse", she said. Over the course of a day you might be picking up those bacteria and then if you suddenly decide to have lunch at your desk without washing your hands first, you're basically transferring those bacteria into your mouth.
