The present study aimed to evaluate copper (Cu) and zinc (Zn) status in Saudi population. A total of one hundred subjects (50 males and 50 females) of healthy adults Saudi volunteers of 20 years or more were selected. The serum copper and zinc concentrations (μg dL-1) were determined by using flame atomic absorption spectrometry. Food processor plus computer program software were used to analyze the food intakes and to calculate the mean daily intakes of copper and zinc (mg day-1). The effect of sex, age, education, occupation socioeconomic status were also evaluated. The mean dietary intakes and serum levels of copper in women were significantly (p<0.05) higher than that found in men. Whereas, the mean dietary intakes and serum levels of zinc in men were significantly (p<0.05) higher than that found in women. Also, there were positive and statistically significant correlations between these trace elements and their serum levels (r = 0.31, 0.28 for copper and r = 0.29, 0.27 for zinc in men and in women respectively, p<0.05). There were no significant variations in dietary intakes or serum concentrations of copper and zinc due to differences in age, education, occupation and socioeconomic status. |

Body weight, total daily energy intake as well as biochemical parameters of serum glucose, total cholesterol, high and low density lipoprotein cholesterol, total protein and uric acid were measured in a group of 45 volunteers of Saudi Arabian healthy Muslim men at pre and at end of Ramadan, the Muslim month of fasting. Body weight, total daily energy intake and the qualitative compounds of nutrients were significantly decreased (p<0.05) at the end of Ramadan. There was a significant decrease (p<0.05) in the levels of serum glucose, serum total protein and serum triglyceride. In contrast, there was a significant increase (p<0.05) serum in uric acid. There were no significant changes in the levels of serum total cholesterol and high and low density of lipoprotein cholesterol. It was concluded that Ramadan fasting could induce weight loss through restriction diet and energy intake with consequent little changes in biochemical parameters. These changes were within normal reference range of pre Ramadan values and appear to be reversible. |

Research suggests that omega-3
fatty acids (n-3 FAs) play an important role in reducing the risk of
heart diseases. The objectives of the current study were to investigate
the consumption and the food sources of n-3 FAs in two samples of elderly
men living in different geographic locations (coastal and internal regions)
of Saudi Arabia. Sixty men from each of the coastal and the internal
regions provided a 24-hour recall and 2-day food record and a food frequency
questionnaire. Food Processor Plus computer program software (ESHA Version
0.7; Salem, Oregon, 2002) was used to analyze the dietary intake. The
intake of total n-3 FAs, alpha-lenolenic acid (ALA), eicosapentaenoic
acid (EPA) and docosahexaenoic acid (DHA) were higher among the coastal
region residents than among the internal residents (P < 0.05). English
walnuts, salmon, canola oil, malabar cavalla and king mackerel were
the top five foods contributing to the n-3 FA intakes in the coastal
region. The top five foods contributing to the n-3 FA intakes in the
internal region were English walnuts, lamb, whole milk, baked beans
and chicken. The food contributing the most to the intake of n-3 FAs
in both regions were English walnuts. In conclusion, the food consumption
pattern for food providing n-3 FAs differs by location and coastal residents
consume more than twice as much n-3 FAs as internal residents. Nutrition
education intervention among internal residents is needed for increasing
the consumption of n-3 FAs. |
