Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Oxidative stress caused by increased production of free radicals due to altered antioxidant enzyme defense, increased lipid peroxidation and reduced levels of essential fatty acids. It is possible that the oxidative injury can be prevented by dietary supplementation of omega 3 fatty acid and antioxidants. Omega-3 fortified eggs might be helpful in decreasing oxidative stress in healthy human subjects. Efficacy study of omega-3 fortified eggs was conducted against oxidative stress through biochemical analysis of biomarkers of oxidative stress e.g., catalase and superoxide dismutase.Eighteen volunteers were selected and divided in three groups (control, omega-3 supplements + vitamin E and omega-3 fortified eggs). At 0, 30th and 60th day, blood sample was collected and further examined. The data will be analyzed through Analysis of Variance with repeated measures (rANOVA) technique. The significance level will be defined as P ≤0.05 and means will be compared through Duncan’s Multiple Range test for significance difference. Omega-3 bio fortified eggs that would be useful for decreasing the oxidative stress in healthy human subjects.P value is less than 0.05 and results indicate that omega 3 fortified eggs may helpful in decreasing oxidative stress in humans. Also results showed that omega 3 fortified eggs are helpful in improving lipid profile by increasing HDL levels and decreasing LDL levels, decrease in triglyceride and cholesterol also a plus point of this product as it is economic, easy to access and nutritious.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Poor nutritional status during pregnancy is a contributory factor in maternal and infant morbidity and mortality. Widespread household food insecurity (58.1% households are food insecure) and poor knowledge about nutrient requirements in pregnant and lactating women are the major cause of nutritional deficiencies. This study is planned to assess nutrients’ intake among pregnant and lactating women and to compare with standard requirements. A cross sectional survey design was used to assess the nutrients’ intake of 110 pregnant and 110 lactating women from 6 Union Councils (two urban, two per-urban and two rural Union Councils) of Lahore and Rajanpur districts. Nutrients’ intake was assessed by using a pre-tested structured questionnaire to interview the pregnant and lactating women at one point in time. Weight, height and mid upper arm circumference was measured through anthropometric measures, 24 hour dietary recall, and food frequency was used to assess nutrients’ intake. The data was analyzed bychi-square and cross tabs using SPSS version 20.0 and was presented in percentage, frequencies and charts to assess the nutritional deficiencies.Significance level was defined as p≤ 0.05. The results shows that majority of the women were deficient in energy and nutrient's intake through daily diet. In both districts pregnant and lactating women were not consuming their required amount of various nutrient's according to their maternal status. Results show significant difference in Lahore and Rajanpur districts most of the nutrient's deficiency was present in Rajanpur as compare to Lahore. Severely low dietary intake of various nutrients was calculated and analyzed. According to the results dietary intake of various nutrients was severely low in selected women with following percentage protein was 39.1%, folate 40%, B12 20.5%, B6 74.5%, vitamin C 30.5%, vitamin A 14.1%, vitamin D 69.1%, calcium 26.8%, iron 96.8% and zinc 70.9%. These results shows very adverse situation of important nutrient's intake of pregnant and lactating women through diet.
