Food substitution with worker feeding programs: energy supplementation in guatemalan sugarcane workers.
An energy supplementation program provided free of charge a low energy (15 kcal) and a high energy (350 kcal) soft drink to two group of sugarcane workers in Guatemala. The high energy supplement supplied 550 kcal/day on a weekly basis. The workers tended to be moderately energy deficient before supplementation. Significant increases in total daily energy intake were obtained with the high energy supplement, but by less than the energy content of the supplement. Workers maintained energy balance with supplementation. The degree of substitution with energy supplementation was not related to the energy intake status of the workers' households. These households did generally not improve their energy intake status with worker supplementation.
