RESEARCH PROJECTs Effect of hypoenergetic high protein diet in contrast to hypoenergetic high carbohydrate diet on weight loss, metabolic rate and hyperinsulinemia in obese, normal and hyperinsulinemic male subjects. OBJECTIVE: To test the hypothesis that hyper and normoinsulinemic obese subjects would respond differently with respect to weight loss and certain metabolic parameters to changes in composition of hypoenergetic diets.
RESULTS: On the HP diet, weight loss was significantly
higher in the HI as compared to the NI group. The HC diets resulted in a
considerable reduction in REE in both HI and NI groups. Fasting insulin
levels decreased in both HI and NI subjects. However, the insulin levels
normalized to below 25 mU/ml with HP diet. CONCLUSION: Hyperinsulinemic obese subjects, in contrast to normoinsulinemic obese subjects, achieve better weight reduction, similarly less decline in energy expenditure, and normalization of insulin levels on high protein hypoenergetic diet. Hwalla, N. Supported by URB (1999-2000) Completed or in progress at AUB Prevalence and selected determinants of iron deficiency
anemia in pregnant women in Lebanon This study investigated the prevalence and determinants of
iron deficiency anemia in Lebanese pregnant women with different
socioeconomic statuses. A sample of 306 pregnant women was selected from
Beirut and Tripoli, attending either Out Patient Departments (OPD) or private
clinics. Results showed that an average of 18.60f Lebanese pregnant
women had deficient hemoglobin levels. The percentage of hemoglobin
deficiency in Lebanese pregnant women increased with gestation age. Iron
stores, as measured by serum ferritin, were deficient in 39.50f pregnant
women. Iron deficiency anemia, as measured by plasma transferin receptor
(P-TfR), was in approximately 41.10f pregnant women. Dietary intake
data showed that serum ferritin deficient pregnant women with plasma
transferin receptor (P-TfR)>8.5 mg/l had lowest animal protein and heme
iron intake. Diet seems to be an important factor contributing to the deficiency prevalence. Hwalla, N. Supported by LNCSR (1999-2000) Completed or in progress at AUB Assessment of malnutrition in older adults from
different socioeconomic backgrounds in Lebanon The study assessed the nutritional status of elderly Lebanese and investigated the possible factors that could be contributing to their ill health. A random sample of 200 elderly subjects, from different socioeconomic backgrounds, living in institutions and at home, was selected. Anthropometric, biochemical and dietary results demonstrated a higher degree of undernutrition and anemia in the elderly living in institutions as compared to those living at home. With the exception of calcium that was adequate for the elderly living in institutions, inadequate intakes of energy, zinc, iodine, magnesium, alpha-tocopherol and vitamins A, D, B6 were noted in both groups and were more pronounced in the elderly living in institutions. In conclusion, nutrition education addressed to the elderly is encouraged, in order to provide appropriate information useful in daily food selection. Moreover, institutions should not only provide the adequate food but also ascertain that the food is being consumed by the elderly persons. Hwalla, N., and A. Sibai. Supported by LNCSR (2000-2001) Completed or in progress at AUB Effect of hypoenergetic high protein diet in contrast
to hypoenergetic high carbohydrate diet on weight loss, metabolic rate and
hyperinsulinemia in obese normal and hyperinsulinemic female subjects This study attempts to test the hypothesis that hyperinsulinemic obese female subjects are a sub-group of the obese female population which is sensitive to diet composition in weight-reducing regimens.
Results will determine whether hyperinsulinemic normoglycemic obese females differ from normoinsulinemic normoglycemic ones in their response to variations in diet composition as far as weight reduction, blood parameters, and composition of weight loss are concerned. Hwalla, N., and N. Torbay. Supported by URB (2000-2001) Completed or in progress at AUB Microbiological quality of some traditional Lebanese
fast foods Because of the present lifestyle in Lebanon, a major part
of the population is eating a variety of fast foods on a daily basis. Recent
studies on the safety of these foods are lacking. Lack of sanitation and
proper cooking of these foods present a public health hazard associated with
their consumption. Determination of shelf-life of labneh (concentrated yogurt) Concentrated yogurt, labneh, produced by straining yogurt in a cloth bag and with a nozzle separator, was stored at 5C, 15C and 25C and monitored for changes in selected microbiological, physico-chemical and sensory parameters. Total plate count, psychrotrophic count, phsycrotrophic yeasts, yeasts and molds, lactic acid bacteria and coliforms were enumerated, and physico-chemical tests, including pH, titratable acidity and syneresis were carried out along with sensory testing of the stored products. Flavor difference, surface smoothness, yeasts and molds count and phsycrotrophic yeasts count were the most correlated quality indices, according to Spearman's rank test. Failure times as determined by specific cut-off points for flavor, surface smoothness, yeasts and molds count and psychrotrophic yeasts count, were fitted to Weibull's distribution to determine the time at which the product is expected to fail at different probability levels. At 95 onfidence level, the nominal shelf-life of nozzle-type labneh, at 5C, ranged between 18.5-19 days, at 15C, between 8-9 days and at 25C, between 63.9-73.2 hours. The nominal shelf-life of cloth-bag labneh ranged between 8.5-10.5 days, 4.7-5.8 days and 54.8-65.3 hours at 5C, 15C and 25C, respectively.
