Protein-energy supplements to preserve nutritional status of sugar cane cutters

Sugar cane cutters in south-eastern Brazil are temporarily hired for the harvest period of 8 months. They often have minimal benefits and may not receive adequate nutrition.

To evaluate alterations in weight and body composition of sugar cane cutters during harvest with the use of protein-energy and electrolyte supplements.

Three products were used daily: a milk drink, a seasoned manioc meal mixture and an electrolyte replacement fluid, adding approximately 398 kcal and 28.5 g of protein/day.

There were small, but significant, reductions in body mass index and percentage body fat with maintenance of lean mass. There was a significant improvement in hydration status, serum albumin and cholesterol. There were no medical absences related to dehydration.

Even though alterations in body mass and biochemistry were small, the significance of the findings suggests these supplements may have a useful role to play in reducing lean mass losses and maintaining nutritional and hydration status of these workers.
