“…Serum Zn concentrations and Zn/Cu significantly increased in the individuals with consumption of alcohol beverage (P<0.05) presenting the highest level in individuals with drinking more than 5 days/week, but still no significant differences were found in serum Zn concentrations and Zn/Cu. And serum Zn/Cu was increased with frequency of drinking, which was in agreement with that of moderate ethanol consumption which raised serum Zn concentrations [28]. Some authors [29,30] demonstrated that physical exercise produced redistribution and changes of trace elements such as Cu in human blood and tissue.…”

“…18 [27] and lower concentration of serum Cu in smokers with no significant difference [17] were reported. And Frimpong and Louis-Charles [28] pointed out that moderate ethanol consumption raised serum Cu concentrations but had no effect on Cu dietary intakes. Serum Zn concentrations and Zn/Cu significantly increased in the individuals with consumption of alcohol beverage (P<0.05) presenting the highest level in individuals with drinking more than 5 days/week, but still no significant differences were found in serum Zn concentrations and Zn/Cu.…”

Sera of 890 healthy Jinan residents were chosen randomly, and the concentrations of serum Zn and Cu were detected by atomic absorption spectrometry. The mean serum Zn and Cu concentrations and Zn/Cu were 1.32 +/- 0.49 mg/l, 0.99 +/- 0.26 mg/l, and 1.41 +/- 0.56, respectively. Significantly higher levels of serum Zn and Zn/Cu but lower serum Cu were found in the men. Descending tendency of serum Zn and Zn/Cu was observed with social-economic status and age but not significant. Alcohol consumption produced higher level of serum Zn and Zn/Cu but lower Cu concentration. Smoking caused significant lower level in serum Cu concentration but no significance in serum Zn and Zn/Cu. Serum Zn and Zn/Cu were normal only when hours of sleep a night were kept within 7-9 h. Higher level of serum Zn and Cu concentrations and Zn/Cu were observed in individuals with regular physical exercise, but still no significant difference existed. No clear relationship between educational levels with serum Zn and Cu concentrations and Zn/Cu was observed.

“…Differences were however not significant. It is possible that moderate ethanol consumption which raises serum Cu concentrations but not dietary intake [47] could be responsible for this, as urban dwellers are more likely to consume more alcohol than rural dwellers, because of the socioeconomic differences. Furthermore, urban dwellers are more active than rural dwellers, and some authors have demonstrated that physical exercise produces redistribution and changes of trace elements such as Cu in human blood and tissue [48,49].…”

Deficiencies in Cu, Se, and Zn impair one or more biochemical functions, and excess are associated with toxicity. Baseline studies on the Ghanaian population are scanty. The study was undertaken to determine whether significant rural/urban differences in the serum levels of Cu, Se, and Zn did exist. Forty males/60 females from rural and 50 males/50 females from urban Ghanaian communities were sampled. Serum Cu, Se, and Zn were determined using flame atomic absorption spectrometry. Cu level for rural and urban subjects was 997 +/- 333 and 979 +/- 290 microg/L, respectively (p = 0.68). However, Cu levels were significantly higher in the rural females (1,063 +/- 367 microg/L) than the rural males (898 +/- 249 microg/L; p = 0.0085). Se levels for rural/urban subjects were 97 +/- 36 and 87 +/- 31 microg/L, respectively (p = 0.03). Zn levels in the rural/urban subjects were 312 +/- 218 and 150 +/- 102 microg/L, respectively (p = 0.002). Additionally, Zn was significantly higher in rural females (428 +/- 204 microg/L) than the urban females (166 +/- 103 microg/L; p = 0.0002). Finally, Zn was significantly higher in rural females (428 +/- 204 microg/L) than males (172 +/- 116 microg/L; p = 0.0028). In conclusion, Cu, Se, and Zn were higher in the rural group compared to the urban group, and the generally low Zn levels were confirmed in another cohort follow-up study.

“…57 In these studies two-thirds of subjects had low zinc intakes but previous studies have shown that, in controlled drinking studies, moderate intakes of ethanol, (40 g/day) does not influence nutritional status of this micro-nutrient and indeed plasma levels actually rise without changing urinary concentrations. 58…”

Nutritional intake of hazardous drinkers and dependent alcoholics in the UK

2003

There are no recent assessments of nutritional intake in alcohol misusers in the United Kingdom. The purpose of this study was to measure nutritional intake in alcoholics attending an Alcohol Misuse outpatient clinic in an inner city general hospital in the United Kingdom and relating this to various measures of alcohol dependence. All patients (n = 30; 27 male, 3 female) consumed at least 100 g ethanol per day (mean 162 g/day) for at least 5 years and completed questionnaires on socio-demographics, alcohol dependency and psychosocial problems and had assays of biochemical and haematological indices. The data were analysed first with respect to the entire patient population and then according to the degree of alcohol dependency (mild, moderate or severe). The results showed that with respect to the entire patient group, one-third were below normal body weights, but one-quarter was overweight. The total energy intake (kJ/day) including alcohol was apparently adequate with respect to recommended levels in most patients. On average, approx. 60% of energy intake came from alcohol. The whole patient population had a low intake of one or more macro- and micro-nutrient compared to the dietary reference requirements. All patients had intakes of vitamin E and folate below UK recommended standards, while 85 - 95% of patients had low intakes of selenium and Vitamin D. Between 50 and 85% of all patents had intakes below UK recommended standards in calcium and zinc and Vitamins A, B(1), B(2), B(6) and C. There were significant correlations between calorie intake (when alcohol was excluded) and vitamins B(1), B(2), B(6) and C, and Ca, Mg, Fe and Zn intake. There were no correlations between alcohol intake with any of the nutritional and anthropometric variables or between the three subgroups with respect to daily energy, micro- and macro-nutrient intakes. In conclusion, malnutrition was common in this patient group: all subjects had intakes below UK recommended standards in one or more micro- or macro-nutrient. However, there was no difference in the degree of malnutrition between the harmful drinkers (mild dependency) and heavily dependent subgroups.
