Publisher: 2015Dissertation note: Food are not only used to satisfy hunger or provide nutritional support but also used to prevent diseases that are based on nutrition and thus improve the health of consumers (Menrad, 2003).A food that is same in appearance and consumption to conventional food but has physiological benefits and prevents diseases is known as functional food (Sangwan et al. 2011). Functional foods are used to provide benefit to intestinal microflora. The most important functional food are prebiotic and probiotic. The combination of prebiotic and probiotic are known as synbiotics. The symbiotic is effective as that of prebiotic and probiotic. The probiotic is used to reduce the impurities from prebiotic mixture. This is very important to know the functional property of functional food (Sangwan et al. 2014) that is galactooligosaccharides (GOS) in present research.
GOS are most effective prebiotic which are beneficial to intestinal microbiota. Other health effects are stool improvement, mineral absorption, weight management and also improve the growth of Bifidobacterium and Lactobacillus (Macfarlane et al. 2008). The Saccharomyces boulardii is a non-pathogenic yeast and used as probiotic. It is thermo tolerant yeast and optimally grows at body temperature i.e; 37ºC. Due to this property S. boulardii can be used for the treatment of gastrointestinal diseases. Another function of this yeast is the reduction of monosaccharides from prebiotic mixture.
The purposes of present research work are to reduce the monosaccharides form mixture of GOS and the production of synbiotic product containing GOS and S. boulardii. For this GOS
were produced through transgalactosylation procedure using lactose as substrate. S. boulardii was grown separately and incubated with the mixture of GOS. After that symbiotic product was formed and lyophilized it. The total count of yeast was determined in lyophilized mixture. The in vitro bifidogenic effect of GOS and lyophilized product was also checked.

Publisher: 2015Dissertation note: Anemia is defined as, low concentration of hemoglobin. IDA is the most prevalent form of anemia especially in developing countries. It becomes more threatening in pregnancy. It is greatly linked with dietary habits choices. It can be substantially improved with proper dietary choices which can be improved by nutrition education. Low dietary intake of iron in pregnancy may be improved by nutritional education. Gravidas females will be divided into two groups; Group A (Controlled group) and Group B (experimental group). Group B will be guided by nutritional education about the IDA, but Group A will not be guided. Clinical tests of patients will be performed three times, with an interval of one month. CBC and serum iron level test will be conducted. The data will be analyzed by t-test using SPSS version 20.0. P values ≤ 0.05 will be considered significant.
This study will help to assess the relationship of Iron deficiency anemia with pregnancy in relation to dietary intake.

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.

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.

Publisher: 2015Dissertation note: Food safety is a scientific discipline describing handling, preparation, and storage of food in ways that prevent food borne illness. This includes a number of routines that should be followed to avoid potentially severe health hazards. The tracks within this line of thought are safety between industry and the market and then between the market and the consumer. In considering industry to market practices, food safety considerations include the origins of food including the practices relating to food labeling, food hygiene, food additives and guidelines for the certification systems for foods. In considering market to consumer practices, the usual thought is that food ought to be safe in the market and the concern is safe delivery and preparation of the food for the consumer.
Heavy metals are presentin sweets like candies, chocolates and gums, which are favorite food for children and pregnant women. Lead, Nickel and Chromium are major toxic heavy metals. Main source of lead exposure in children are food, air, water and soil.Accumulation of Lead in different parts of the body has adverse effects and causes many diseases.When chromium is ingested in excess amounts, it induces many toxicity symptoms in human body. At higher levels, nickel accumulates in the lungs and may cause bronchial haemorrhage. Other symptoms include nausea, weakness, dizziness, etc.
In Pakistan food safety is on the verge chaos specially there is no sufficient data available on heavy metals in confectionary products. Therefore present study was designed to aware the consumer specially children about hazards of heavy metal in candies and chocolates.
Both Local and imported Candies and Chocolates samples (n=120) were collected from local shops anddepartmental stores of Lahore. Samples were analyzed by Atomic absorption spectrometer for heavy metals examination in Environmental Science DepartmentLaboratory of University of Veterinary and Animal Sciences.
Concentration of lead in imported candies (n=30) and local chocolates (n=30) found within acceptable value 0.5 mg/kg of Punjab Food Rules 2011(PFR) while imported chocolates (n=30) and local candies (n=30) were not found within acceptable value 0.5 mg/kg of PFR 2011. The variation of nickel was not found within permissible value 0.025 mg/kg of PFA in all (n=120) imported chocolates, local chocolates, imported candies and local candies. Concentration of chromium in all types of samples (n=120) was high as compared to limit value 0.02 mg/kg of PFR 2011.

Publisher: 2015Dissertation note: Metabolic syndrome can be defined as disorder of energy utilization and storage, its diagnosis can be done if three out of five medical conditions occurs at the same time that are abdominal obesity, increased blood sugar level, elevated blood pressure, high serum triglyceride and low HDL levels in serum Previous studies have shown that there is strong association between skipping breakfast and metabolic syndrome.
Skipping breakfast results in metabolic diseases like obesity, cardiovascular disease, high blood pressure, diabetes, increased lipid profile.
Two hundred students of university of veterinary and animal sciences and their acquaintances were selected with age ranging from 20-25 years. Fasting blood samples were collected from university students for biochemical analysis of lipid profile that included cholesterol, triglyceride, HDL and LDL and Glucose levels were determined using biochemical analyzer (Micro lab 300, Merk). Anthropometric measurements were done using their respective tools.
The distribution of subjects in breakfast consumption groups was evaluated using the χ2 test. The mean and standard differences deviation were calculated for each breakfast consumption group.
At the end it is concluded that skipping of breakfast might have hazardous effect on diet quality and metabolic disease risks. This can lead to development of potential hazardous risk factors like central abdominal obesity, elevated cholesterol, triglycerides and LDL levels and decreased HDL levels. These risk factors if uncontrolled can lead to disease like diabetes, hypertension and heart attack in old life. Availability: Items available for loan: UVAS Library [Call number: 2391-T] (1).
