Cholinesterase inhibitory activity, antioxidative potential and microbial stability of innovative liver pâté fortified with rosemary extract (Rosmarinus officinalis)

Background: Rosemary (Rosmarinus officinalis) contains active substances that have desirable properties for industrial and herbal medicine applications, e.g., essential oils (1.5­2.5%), tannins, flavonoids, triterpenes, saponins, resins, phytosterols, rosmarinic acid and many others. The aim of this study was to determine the influence of rosemary extract and 20% rapeseed oil substitution for animal fat on storage changes and inhibition of cholinesterases in liver pâté. Results: Preliminary research showed that rosemary extract exhibited antioxidative activity in the system of accelerated Rancimat and Oxidograph tests. Then, rosemary extract was used as an ingredient in liver pâté. During the experiment, meat samples were refrigerated and tested on days 1, 5, 8, 12 and 15 after production. The study proved that the substitution of 20% of animal fat with rapeseed oil decreased the content of saturated acids and increased the content of monoenic fatty acids by approximately 5% and polyene fatty acids by 40%. Conclusions: In addition to antioxidative activity, the rosemary extract affected the health-promoting value of the samples, which inhibited cholinesterase activity during the entire storage period. The extract inhibited AChE more than BChE.

Characterization of the Physicochemical Properties of Different Biodiesel Samples

ABSTRACT For combustion engines to perform well, it is necessary that the fuel used be of high quality. Fuel quality can be analyzed through different physicochemical properties. This study presents comparisons between the values presented in literature, legislation and those obtained through experimental tests of different biodiesel samples. Biodiesel is a promising alternative of renewable energy obtained from raw material. The properties observed in this study are: Viscosity, density, cloud point, pour point and calorific value. The data explored by this work aims to bring solidification to the methodologies and equipment necessary for a better characterization of biodiesel.

Beef tallow and emulsifier in growing-finishing pig diets

ABSTRACT Two trials were aimed to evaluate beef tallow in diets with and without emulsifier on performance of pigs at growing-finishing phases. In the first trial, 15 barrows (22.03±0.62 kg) were distributed among three treatments: reference diet; test diet 1 (5% beef tallow) and test diet 2 (10% beef tallow). Beef tallow presented average value of 7130.97 kcal ME/kg. For the performance trail, 30 barrows (24.85±1.18 kg) were distributed among five treatments: T1 - diet with soybean oil and 3230 kcal ME /kg; T2 - diet with beef tallow and 3230 kcal ME/kg; T3 - diet with beef tallow and 3080 kcal ME/kg; T4 - diet with beef tallow, 3080 kcal/kg and 0.1% emulsifier; T5 - diet with beef tallow, 2930 kcal ME/kg and 0.1% emulsifier. Feed conversion was worse in animals fed diet with 3080 kcal ME/kg containing beef tallow and with 2930 kcal ME/kg with beef tallow and emulsifier. For economic availability, animals fed diet with beef tallow and 3230 kcal ME/kg and those fed diet with 3080 kcal ME/kg containing beef tallow and emulsifier, did not differ from animals fed diet with soybean oil, which enables the reduction up to 150 kcal ME/kg be compensated by emulsifier addition.

A Comparative Study of Eating Habits and Food Intake in Women with Gestational Diabetes according to Early Postpartum Glucose Tolerance Status

BACKGROUND: Women with gestational diabetes mellitus (GDM) are at high risk for type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD); continuous life-style intervention, especially diet, is central to managing T2DM and CVD. However, little is known about the dietary patterns of women with GDM after delivery. The goal of this study was to compare the eating habits and food intakes of women diagnosed with GDM during the early postpartum period. METHODS: We performed a 75 g oral glucose tolerance test (OGTT) in 184 women with GDM between 6 and 12 weeks after delivery. Based on the results of the OGTT, the subjects were divided into three groups according to the American Diabetes Association criteria; normal glucose tolerance (NGT) (n=100), pre-diabetes (n=73), and diabetes mellitus (DM) (n=11). Eating habits and usual food intake after delivery were investigated using a questionnaire, based on 24 hour-recall, which was administered by a trained dietitian. The daily intake data were analyzed using CAN Pro 3.0. Blood tests were performed pre- and post-delivery. RESULTS: Eating habits were not significantly different among the three groups. However, animal fat consumption was significantly different among the three groups. The intake ratio of fat calories to total calories was also significantly higher in the pre-diabetes and DM groups. CONCLUSION: Although diet in the period 6 to 12 weeks postpartum did not influence glucose level, it may be important to educate women with GDM about the risks of excessive animal fat intake during pregnancy and the postpartum period in order to prevent later onset of T2DM.

A Study on the Characteristics of Nutrient Intake in Metabolic Syndrome Subjects

This study was conducted to investigate the prevalence of metabolic syndrome (MS) and characteristics of nutrient intake in MS subjects by gender and age. The subjects were 957 (447 men and 510 women) who visited medical center for regular medical check-up. The diagnosis of MS subjects was adapted from NCEP-ATPIII with blood glucose, cholesterol, triglycerides, and blood pressure and Aisa-Pacific definition with waist-circumference. Anthropometric and biochemical measurements were practiced, then the nutrient intake analysis was assessed through the 24-hour recall method. The MS prevalence of all subjects was 10.3% in average -17% in men and 4.5% in women, respectively. The energy intake in MS group was 2047.1 kcal and 1699.5 kcal for normal group, showing significantly higher in MS compared to normal subjects. For intakes of animal fat, cholesterol, and sodium, MS group were significantly higher than normal group. In respect of gender, men subjects of MS group showed significantly higher nutrient intakes than normal group for energy, fat, and cholesterol. Women subjects of MS group showed higher intakes for energy, carbohydrate, and protein. For 30s, MS group showed higher intakes of energy, animal fat, and cholesterol than normal group. Fat and cholesterol for 40s and energy, carbohydrate, vegetable fat for 50s, MS group showed significantly higher intakes than normal group. In summary, MS group showed higher intakes of energy, animal fat, cholesterol, and sodium than normal group.

Diet and Lifestyle Risk Factors of Benign Prostatic Hyperplasia

Benign prostatic hyperplasia (BPH )is one the most common prostate diseases in middle aged and elderly men. This study was conducted to investigate diet and lifestyle risk factors for benign prostatic hyperplasia in a community-dwelling free-living population group. The dietary data were collected from the 601 male subjects aged 50 -79 years using the 24-hour recall method. The mean age of the BPH group (63.0 +/- 7.9 years )was significantly higher than that of the non-BPH (58.8 +/-7.4 years ). Among many nutrients, the amount of animal fat intake was increased while that of carbohydrate intake decreased in subjects with BPH compared to those with non-BPH. In BPH subjects, the proportion of energy from fat was also greater than in subjects with non-BPH. The logistic regression analysis on the food con-sumption data showed that the consumption of total animal food was increased while that of mushrooms was decreased in patients with BPH compared to the subjects with non-BPH. The age-adjusted odds ratios and 95% confidences limits for BPH incidence in subjects whose milk and milk products, beverages and alcoholic liquors intake was greater than the median were 1.796 (1.167 -2.782 )and 1.738 (1.129 -2.676 )respectively, compared to those in subjects whose intakes were below the median. These results may be applicable in the development of a nutrition intervention and education program toward a reduction in the risk for benign prostatic hyperplasia.

Asia Pacific menu patterns in relation to lipid abnormalities: An Indonesian perspective.

Countries in the Asia-Pacific region differ widely with respect to their nutritional intake and nutritional status. The highest daily energy and proportion of fat intakes of the population is shown by the New Zealanders (total energy 3475 Kcals; fat proportion 37.2% or 1293 Kcals), while the lowest is the Siamese (total energy 2288 Kcals; fat proportion 13.1% or 300 Kcals). The Indonesian on the other hand, is at the third from the bottom (total energy 2631 Kcals; proportion of fat is 14.5% or 381.9 Kcals). Animal fat contributes to 29.7% (1033 Kcals) of the total daily energy intake of the New Zealanders (total 3475 Kcals), and the mortality rate coronary heart disease (CHD) is also the highest (228 per 100,000 populations for men and 173 for women). In contrast, the proportion of animal fat in Indonesian menu is only 1.47% (38.7 Kcals) of the total daily energy intake, while the CHD mortality rate is still below 50 per 100,000 for both men and women. Compared to the same values fifteen years before, animal fat intake of the New Zealanders has a decrease of 90%, Australian 88%, Philippines 99%, however the Indonesian on the other hand, has an increase of 157%. In New Zealand and Australia, the proportion of mortality attributed to cardiovascular disease (CVD) for men accounts for over 40% of total mortality. Japan however, the proportion mortality rate for CVD is only less than 30% of total mortality. In this level, Japan places itself among less industrialized group such as Malaysia and the Philippines. In the case of cerebrovascular (stroke) mortality however, Japan belongs to the highest category group. It seems that apart of high fat intake, stress and possibly also other factors play a major role in the development of stroke. The mean Indonesian total energy intake is 2631 Kcals, consisting of 8.7% protein (228.9 Kcals, 52.2 g), 76.8% carbohydrate (2020 Kcals, 505 g), and 14.5% fat (381.9 Kcals, 42.4 g). Animal fat intake is only 4.3 g/day (38.7 Kcals) which is 1.47% of the total energy intake. Although appears to be low, but it has a 157% increase if compared to the same value fifteen years before. Indonesian CHD mortality rate is still relatively low (below 50 per 100,000), however it is only a matter of time that the this value will soon increase in line with the increase of fat (especially animal fat) and total energy intakes.

Association between Nutrient Intakes and Benign Prostate Hyperplasia

Benign prostatic hyperplasia (BPH) is the most common prostate disease in middle aged and elderly men. Therefore, identifying risk factors for BPH is crucial for understanding the etiology and for undertaking interventions or targeting strategies. The survey was carried out in two steps: first, pilot study was conducted prior to the main study in order to estimate baseline characteristics. Second, main study investigated prevalence and risk factors of BPH by clinical diagnostic tests and questionnaire. A total of 641 male aged 50-79 years participated in this community-based crosssectional study. Using 24 hour recall of food consumption, we found that animal fat intakes increased the risk of BPH with adjusted for age, chronic bronchitis, PSA level, drinking frequency, and excercise frequency (odds ratio 1.84, 95% confidence interval 1.10-3.06). Although BPH has been considered as unavoidable disease with advancing age, if these dietary risk factors are clearly identified, it can be prevented effectively by laying special emphasis on those at risk.
