ABSTRACT

The effect of instantcoffee (nescafe) intake on plasma total creatine kinase (CK) and weight were examined on 30 apparently healthy persons within Port Harcourt metropolis. A total of 60 blood samples were collected (30 samples before coffee intake and 30 after coffee intake). Instant coffee (black) was consumed for 14days with a dosage of one teaspoonful of coffee with 70millilitres of hot water twice daily (morning and evening). Results obtained indicated significantly higher values of 142.9±34.06 in total CK levelafter coffee consumption compared with 133.1±27.33 before coffee consumption when the overall subjects (male and female combined) were analyzed at p<0.01. Similarly, when female subjects were considered, results obtained also indicated significantly higher values of 164.3±35.16 in total CK after coffee consumption compared with 144.6±32.60 before coffee consumption at p<0.01. Additionally, the comparison of male subjects showed no significant differences in CK levels and weight before and after coffee consumption. Furthermore, the analysis of data obtained indicated significant increase in the weight of female subjects with value of 65.8±5.69 compared to male subjects with 61.14±3.26 before coffee consumption. However, no significant difference was observed in CK level. Finally, significant increase in the CK of female subject with value of 164.3±35.16 compared to male subjects with 132.1±28.68 after coffee consumption was also observed. Also, significantly higher value of 65.21±5.62 was observed in the female subjects compared with 60.87±3.24 in the male subjects when weight was considered. The study indicates that consumption of caffeinated coffee of 2 cups daily for a period of 14 days (short-term) by non-habitual subjects induced increased CK level. However, no significant differences were seen in the weights of these subjects.
