The global spread of diet-related noncommunicable diseases represents a threat to public health and national economies alike. The elimination of poverty and the eradication of hunger, two key United Nations Sustainable Development Goals, cannot be accomplished without a well-nourished labor force. Easy access to low-cost diets that are energy dense but nutrient poor has resulted in hidden hunger, in which micronutrient deficiencies coexist with obesity or overweight. Workplace interventions in low- and middle-income countries have addressed nutrient adequacy and micronutrient deficiencies, often using fortified foods. Workplace interventions in high-income countries have largely focused on weight loss, smoking cessation, stress reduction, and physical activity. Even though improvement of productivity may have been the ultimate goal, relatively few interventions in high-income countries have explored the likely impact of improved dietary nutrient density on workplace performance. Given that optimal nutrition benefits both physical and mental health, interventions to improve diet quality ought to have a measurable impact on the productivity of the labor force. The present review examines the evidence linking workplace dietary interventions with workplace productivity measures.
