RESUMO
The investigators have analysed beverages sold locally. Group I, comprising of mineral water, contains no glucose, low osmolarlity, bicarbonate (11.5 + 3.3 mmol/L) and chloride (23+ 0.4 mmol/L). Group II, comprising of beverages for beverages for athletes, has osmolality rates of H2O (637+ 170 mosm/kg), sodium (11.8+ 13.6 mmol/L), potassium (3.4+ 2.4 mmol/L), bicarbonate (13.6+ 12.3 mmol/L) and chloride (36 + 10 mmol/L). Osmolality rates for Group III, comprising of fruit juices, are H2O (731 + 72 mosm/kg), potassium (11.5 + 6.9 mmol/L), bicarbonate (8.7 + 2.9 mmol/L, chloride (29 + 4.1 mmol/L), calcium (1.9 + 1.9 mg/dl), phosphate (4.8 + 3.0 mg/dl) and magnesium (3.4 + 2.6 mg/dl). In Group IV, comprising of beverages containing caffeine, osmolality rates are H2O (1,245 + 187 mosm/kg), sodium (13.6 + 4.7 mmol/L), bicarbonate (7.6 + 1.2 mmol/L) and chloride (22 mmol/L). All beverages except those under Group I contain glucose. The investigators hope this study will benefit consumers to choose the appropriate beverages for their specific needs.
