Leonurus japonicus H. is a biennial wild plant that grows naturally in Asian countries such as Korea, China and Japan and belongs to Labiatae and has been used in lowering blood pressure, promoting urination, as a pain-killer, sedation and in promoting menstruation. In this study, Leonuri herba’s antioxidant function, improvement were investigated. L. japonicus H. extract was fractioned into Hexane, Ethyl Acetate, Water, H2O, 30% EtOH, 60% EtOH and 100% EtOH. The investigator carried out an experiment of confirming the capability of superoxide erasure by using the DPPH technique of antioxidant experiment and Xanthine oxidase hypoxanthine and measured the activation of antioxidant with ABTS technique. This Study showed that the 30% EtOH fraction was highest in antioxidant effect. Collagense synthesis was significantly increased in the experiment of anti-wrinkle effcet. All the L. japonicus H. extracts inhibited the generation of H2O2 in a dose dependent manner. Based on the above study findings, the anti-aging effect of 30% EtOH fraction of L. japonicus H. was most excellent. In conclusion, the rutin and adenosine of L. japonicus H. extract had a strong antioxidant function. If it is used in cosmetics, a variety of natural functional cosmetics, such as excellent natural moisturizers, antioxidant agents and anti-aging agent, can be developed.

In this study the influence of Elaeagnus angustifolia flour including all parts of the fruit (pulp, skin and core) added at different levels 2.5, 5, 7.5 and 10% on organoleptic and physicochemical characteristics of functional bread (LAVASH) were investigated. The moisture and protein content of treated bread decreased while ash, acidity, glucose, fructose, total sugar, fat content and water activity had been increased compared to control. This flour increased the sweetness of treated samples. Due to technological problems addition of E. angustifolia flour up to 7.5% was more acceptable. Organoleptic properties of treated types were approved by the evaluators.

The plants of Pinus genus have been traditionally used in treatment of several diseases and recent studies revealed new pharmacological and biological activities of the genus. Pinus eldarica (Pinaceae) is commonly known as Tehran pine and planted in many parts of Iran, Afghanistan, and Pakistan. Aromatic water of P. eldarica needle have been used in arthritis rheumatoid complains in Iranian folk medicine. However, there is no study regarding the composition and safety of the aromatic water administration in human, therefore in the present study components of the aromatic water were identified using gas chromatography-mass spectrometry (GC-MS) method followed by evaluation of its probable acute and sub-chronic toxicity in Wistar male rats. The aromatic water was administered with dose of 10-22.5 mL/kg in acute and with dose of 10 mL/kg in sub-chronic toxicity assay for a period of 45 days. Thymol (78.8%) and carvacrol (6.2%) were characterized as the main part of the aromatic water constituents. The results indicated no sign of toxicity and lethality after single and repetitive doses of the aromatic water of the plant with the median lethal dose (LD50) higher than 22.5 mL/kg body weight for male rats. All the hematological and biochemical parameters with histological examination of liver, spleen, kidney, and lung were normal compare to normal saline. There was only significant increase in triglyceride level in the period of 23 days. Therefore, oral administration of the aromatic water of P. eldarica may considered as non-toxic at doses of 10-22.5 mL/kg. Thymol and carvacrol could possibly contribute to the beneficial effect of aromatic water of the plant in arthritis rheumatoid complains.

The prevalence of impaired fasting glucose (IFG) in the general population presents a significant clinical challenge given the high rate of progression to full-blown diabetes and the associated increase in cardiovascular risk and other complications, and justifies the need for early corrective intervention based on lifestyle changes supported by supplements to modulate postprandial glycemic peaks. This open-label study, based on a cross-over model, was conducted on a sample of 25 overweight patients with IFG taking part in a standardized lifestyle intervention program in order to analyze its effectiveness in modulating postprandial glycemic peaks as well as the gastrointestinal tolerability of a specific, standardized polyphenolic supplement (extracted from Ascophyllum nodosum and Fucus vesiculosus). The trend in capillary blood glucose values measured in patients enrolled in the study confirms the ability of the product used to modulate glycemic fluctuations both after ordinary meals consumed in real-life conditions and after a standard meal with controlled intake of carbohydrates, compared to observed values after consuming the same meals without supplements. The homogeneity of the glycemic values observed three hours after the standard meal, both with and without supplementation, also confirms the absence of late hypoglycemic effects.

Background and aim: This study aims to evaluate the association between neck circumference (NC) and several cardio-metabolic risk parameters, to compare it with some anthropometric variables. Methods: A total of 331 women, aged 20-49 years were recruited. Anthropometric measurements (body weight, height, waist and neck circumferences) and biochemical parameters [serum fasting blood glucose (FBG), fasting blood insulin (FBI), triglycerides, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), and fibrinogen] were collected. Homeostasis model assessment-estimated IR (HOMA-IR) was calculated. Results: According to World Health Organization criteria, percentages of women with normal weight, overweight, obese and morbidly obese were 14.2%, 31.7%, 44.7%, 7.9%, respectively. Seventy-one percent of women had NC less than 37 cm, while that of twenty-nine percent of the women had higher. NC was moderately correlated with BMI, WC, FBI, HOMA-IR, and fibrinogen. A positive weak correlation was found between NC and FBG (p=0.031), TG (p=0.000), and LDL cholesterol (p=0.016). Moreover, a negative weak correlation was found between NC and HDL cholesterol (p= 0.000). A positive relationship between plasma fibrinogen and body weight (r=0.222), BMI (r=0.242), WC (r=0.187), TG (r=0.124), and LDL cholesterol (r=0.118) were detected whereas a negative relationship were found between HDL cholesterol and plasma fibrinogen (r=- 0.119) levels. Conclusion: A significant relation is existent between neck circumference and cardio-metabolic risk factors. NC could be used, it is easy to implement, an effective anthropometric measurement to the prediction of cardio-metabolic risks. Its usage together with anthropometric measurements such as waist and hip circumferences, waist-hip ratio and BMI which are widely used to determine cardio-metabolic risks can provide clinical benefits.

Background. Inflammation is the common denominator of atherosclerosis, cardiovascular diseases, obesity, metabolic syndrome and type 2 diabetes. There are studies confirming the involvement of the immune system in acute myocardial infarction, metabolic syndrome, obesity and diabetes. However, data evaluating the relationship between markers of nutritional status and the concentration of immunoglobulins are insufficient. Aim. The aim of this study was to investigate the relationship between selected markers of nutritional status, age, inflammatory markers CRP and immunoglobulin G, A and M in adults. Material and Methods. The study included 114 people aged 45+. Nutritional status was assessed on the basis of anthropometric measurements, lipid profile indicators and fasting glucose. The concentration of the inflammatory marker CRP was determined by the high-sensitivity method and the concentration of immunoglobulin G, A, M by the immunoturbidimetric method. Assessment of the gender differences was based on one-way analysis of variance and analysis of the relationship between nutritional markers, CRP and immunoglobulin based on linear regression analysis. Results. A major problem in the study population was the occurrence of metabolic disorders in the form of excess body weight, lipid profile and carbohydrate metabolism disorders. It was shown that IgA levels correlated positively with waist circumference and WHR. No significant correlations were found between the remaining nutritional status markers assessed, C-reactive protein and IgA, IgG and IgM concentrations. Conclusions. The findings confirm the hypothesis that the immune system is involved in the pathogenesis of obesity, in particular the abdominal type. More research is needed to explore mechanisms which increase serum IgA among obese patients. However, one limitation of this study is the relatively small experimental group. It is necessary to conduct tests on a large population, which could confirm these dependencies.

Consumers are now generally aiming to live a longer life of better quality. For many, this means adopting an alternative lifestyle, consuming more “functional” foods to help deliver the desired quality and also to cope with their increasing health problems. In parallel with increasing health problems in Turkey and the rest of the world, the interest in functional products has increased, and therefore the market share of these products has also increased. This study aimed to determine the attitudes to purchasing these functional foods by interviewing a sample of 1182 consumers shopping at markets. Specifically, survey examined the attitudes of consumers to using 18 functional foods included in the markets in Turkey. A scale that includes 42 statements, developed by Urala and Lahteenmaki (2004), was used in the study. One of the main findings was that the interest in functional food was found to be high in females, university graduates and individuals aged between 18 and 25. Decision-making about purchasing functional food was found to differ by gender and educational level, and this difference was statistically significant. The factors found to have most influence on consumer decisions about purchasing functional foods were “functional foods are necessary” and “functional foods are a part of healthy diet”.

Objective. The effect of calcium intervention equivalent to three cups of milk/ day from dairy foods and 800 mg supplemental calcium as tablets, compared to a control group on normal diets with one cup of milk/ day, was studied on food and nutrient intakes. Methods. A group of 122 healthy adult Jordanian females, age 20-45 years, were recruited in the study during a period of 12 weeks. Study sample was divided into: dairy calcium group, supplemental calcium group, and control group. Intakes of main food groups, energy, carbohydrates, protein, fat, cholesterol, dietary fiber, calcium and vitamin D were evaluated, and their intake adequacies were assessed using the dietary reference intakes (DRIs) and food exchange system at the end of the study. Results. highly significant differences (P 0.05) were obtained between the different treatment groups regarding their intakes of fruits and vegetables. As for energy intakes, the control group exhibited a significantly (p <0.05) higher contribution of energy intake compared to the other intervention supplemented groups. Conclusions. It can be concluded that the postulation that the favorable effects of dairy components on food intake, subjective satiety and intake regulatory mechanisms have been usually observed in short term experiments where the components were consumed in amounts that found in usual serving sizes of dairy products, and in the current study, the milk intake of the milk group seemed to affect satiety and eating pattern of diet and nutrient intakes by lowering food and energy intakes.

Aim: The aim of this study was to examine the effect of seasonal variations on the dietary habits, food consumption, anthropometric measurements, physical activity and some serum vitamin levels of adult females. Methods:The study was conducted during consecutive four seasons in October (autumn), January (winter), April (spring), and July (summer). After general information was obtained about the participants via questionnaire, their anthropometric measurements were taken, and individual records kept for 7-day individual food consumption and 3-day physical activity. Also, their body compositions (Body Stat 1500O) and resting metabolic rates (Ergospirometry-Cosmed K4b2) were measured. Participant serum samples were analyzed for levels of vitamins A, E, β-carotene and 25-OH Vitamin D3. Subjects: Thirty-five healthy, young adult females between the ages of 19 and 24 were invited into a prospective research study. Results: Spring was found to be the season with the highest intake of energy and nutrients compared with other seasons (p 0.05). A significant positive correlation was determined between the levels of serum β-carotene and dietary β-carotene intake in autumn (r = 0.37, p<0.05). Conclusion: It was concluded that seasonal variations have significant effect on the nutritional status, body weights and compositions, daily energy expenditures, and particular serum vitamin levels in individuals. This should be taken into consideration when developing individual nutrition plans and establishing nutrition policies in Turkey, where all four seasons are experienced conspicuously.

Rakıcıoğlu","doi":"10.23751/PN.V20I2.5399","DOIUrl":"https://doi.org/10.23751/PN.V20I2.5399","url":null,"abstract":"Aim: The aim of this study was to examine the effect of seasonal variations on the dietary habits, food consumption, anthropometric measurements, physical activity and some serum vitamin levels of adult females. Methods:The study was conducted during consecutive four seasons in October (autumn), January (winter), April (spring), and July (summer). After general information was obtained about the participants via questionnaire, their anthropometric measurements were taken, and individual records kept for 7-day individual food consumption and 3-day physical activity. Also, their body compositions (Body Stat 1500O) and resting metabolic rates (Ergospirometry-Cosmed K4b2) were measured. Participant serum samples were analyzed for levels of vitamins A, E, β-carotene and 25-OH Vitamin D3. Subjects: Thirty-five healthy, young adult females between the ages of 19 and 24 were invited into a prospective research study. Results: Spring was found to be the season with the highest intake of energy and nutrients compared with other seasons (p 0.05). A significant positive correlation was determined between the levels of serum β-carotene and dietary β-carotene intake in autumn (r = 0.37, p<0.05). Conclusion: It was concluded that seasonal variations have significant effect on the nutritional status, body weights and compositions, daily energy expenditures, and particular serum vitamin levels in individuals. This should be taken into consideration when developing individual nutrition plans and establishing nutrition policies in Turkey, where all four seasons are experienced conspicuously.","PeriodicalId":20600,"journal":{"name":"Progress in Nutrition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47394183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Objective: Vegetarian and vegan diets have gained popularity in Spain. There is no available information about specific food, supplementary intake and macro and micronutrient profile in Spanish ve-getarian population. This study aimed to determine and evaluate their dietary intake. Methods: One hundred two Spanish vegetarian and vegans completed a food frequency questionnaire from which their specific food consumption as well daily intake of macro and micronutrients was assessed and subsequently compared to Spanish Dietary Reference intakes. Results: In both groups the diet appeared well balanced with a healthy distribution of macronutrients and fatty acids and a high content of fiber. Vegan subjects showed higher intakes of vegetables, nuts and seeds as compared to vegetarians. At micronutrient level, almost all the vitamins and minerals intake covered Spanish Dietary Reference intakes. Intakes of vitamin B12 and D were below recommendations in both groups. In those micronutrients with a lower intake, higher proportions of vegetarians did meet recommendations as compared to vegans. Conclusions: Diet appeared well balanced regarding macronutrients and fiber. Almost all of the vitamins and mineral intake covered the Spanish DRIs, except B12 and D. Further studies with a large sample are needed to establish conclusions to the Spanish vegetarian population.
