There was a time when carrying lunch from home was simply part of working life.
A container filled with ugali and vegetables, rice and beans, chapati, stew or leftovers from the previous evening was an ordinary sight in African workplaces.
Today, the office lunch looks different.
Food delivery platforms, shopping-centre restaurants, fast-food outlets and roadside eateries have transformed how urban workers eat during the day.
For many professionals, lunch is no longer something packed at home. It is something ordered between meetings.
The change reflects more than convenience. It mirrors the transformation of African cities, where working hours are longer, commuting takes more time and households have less time to prepare meals.
But convenience can come with a nutritional price.
WHO says rapid urbanisation and changing lifestyles have contributed to dietary shifts, including greater consumption of highly processed foods high in unhealthy fats, salt and free sugars.
Kenya is experiencing the consequences of this transition alongside persistent food insecurity. Recent UN data showed that adult obesity in the country more than doubled between 2012 and 2024, while undernutrition remains a major concern.
That makes the humble lunchbox more relevant than it may appear.
A home-packed meal does not have to be elaborate. Leftover vegetables, beans, a modest portion of starch and a source of protein can form a practical meal.
The challenge is creating workplaces and cities where healthier choices are also convenient and affordable.
This is increasingly becoming a public health question.
As September provides an opportunity to reflect on prevention, perhaps the workplace lunch deserves a second look.
Not because every meal must be perfect, but because what happens repeatedly — five days a week, month after month — eventually becomes part of our health.
