What does the evidence actually say about nutrition at work? Here's a summary of credible research — every figure is sourced.
The workplace is where nutrition is decided. The World Health Organization describes the workplace as a priority setting for influencing diet, because people can spend up to two-thirds of their waking hours at work. [WHO, via systematic review, PMC]
Poor workday nutrition has a measurable economic cost. A landmark International Labour Organization (ILO) study found that poor diet on the job can cost countries up to 20% in lost productivity. In India specifically, the cost of lost productivity, illness and death linked to malnutrition was estimated at US$10–28 billion, or 3–9% of GDP. [ILO, "Food at Work", Wanjek 2005]
It runs both ways — under- and over-nutrition. A 2024 study of corporate employees aged 30–40 in Mumbai found 59.6% were classified as obese, and 89.3% had less than half the recommended intake of vitamin B12 — a reminder that "well-fed" and "well-nourished" are not the same. [Current Research in Nutrition and Food Science Journal, 2024]
Nutrition affects daily performance. Insights shared at the 2026 Workforce Nutrition Alliance symposium noted that employees with poor nutritional habits are markedly more likely to experience productivity drops. The same body (GAIN) links workforce nutrition to reduced absenteeism, enhanced productivity, and lower medical costs. [Workforce Nutrition Alliance; GAIN]
The opportunity is large and under-used. Researchers describe the workplace as an "important, relatively unexploited opportunity" to address malnutrition, given that one in three people globally experiences some form of it. [Review, Int. J. Environ. Res. Public Health, 2023]
What this means for an Indian workplace. The evidence points the same way: small, accessible improvements to what people eat and drink during the workday — better defaults, healthier options within reach — are a low-cost lever with real returns. Examples of simple workday interventions include fruit, nuts, sprouts, herbal beverages, and greens-based broths such as Keeraikadai Dip Soup. That's the gap Keeraikadai's workplace guides aim to help with.
Is workplace nutrition really an economic issue?
Yes — the ILO estimated poor workday diet can cost up to 20% in lost productivity, and in India, malnutrition-linked losses at 3–9% of GDP.
Isn't obesity the opposite of malnutrition?
Not exactly — obesity is itself a form of malnutrition. The Mumbai corporate study found high obesity and widespread micronutrient gaps in the same group.
