ABSTRACT
Hypertension is one of the major risk factor for cardiovascular morbidity and mortality. One of primary management of hypertension include dietary changes which could incorporate dietary supplementation ,also use of non pharmacological treatment options is high in patients with high blood pressure .Garlic has played an important dietary as well as medicinal role in human history and it has been on the top ten lists of herbal sales among people. For evaluating the effect of garlic on blood pressure ,we reviewed clinical trials published from 1982 until 2013 by searching in informative bank such as PubMed ¡Ovid ¡ Elsevier Science , Google Scholar with keywords garlic , blood pressure, hypertension and herbal supplement. The result of this review article showed that several clinical trials have suggested garlic lowers systolic and or diastolic blood pressure and has beneficial effect in controlling hypertension, but negative results also have been obtained in some of trials .Blood pressure reducing properties of garlic have been linked to its hydrogen sulphide production and allicin content , liberated from alliin and the enzyme alliinase. large scale trials are needed to investigate whether standardized garlic preparations could provide a safe alternative or complementary treatment option for hypertension in clinical practice
ABSTRACT
Comparing dietary pattern and related socio-economic factors among adolescent girls in the North and South of Tehran, the capital of Iran. This cross-sectional and analytical study 210 adolescent girls, aged 14-17 years, from high schools in the North district of Tehran [n=105; high socio-economic level] and the South district [n=105; low socio-economic level] were selected by the two-step, cluster random sampling method. Demographic data, including mothers´ and fathers´ educational levels and parents´ occupation were gathered, using a validated self-administered questionnaire. Three questionnaires of food frequency, one-day 24-hour food recall and one-day 24-hour food record were used for assessing dietary pattern. The results showed that the frequency consumption of certain fatty foods, including dairy products and meat group, and fats in district 1 are higher than in district 19 adolescent girls; based on many differences such as life style and food accessibility. This indicated that there is a significant difference in the quality pattern of fat intake between the two districts. It is suggested to design and implement nutritional intervention programs for adolescent girls, particularly in the low socio- economic districts
ABSTRACT
Flavonoids are wide range of phytochemical with various pharmacological effects including antioxidant, anti-inflammation, anti-platelet, anti-allergic, cytotoxicity, reduce risk for heart disease or cancer etc. These flavonoids inhibited various enzymes such as prostaglandin synthase, lypoxygenase, cyclooxygenase, and induced detoxifying enzyme systems such as glutathione S-transferase. Flavonoids have significant vitamin C sparing activity and powerful antioxidants than the traditional vitamins such as quercetin, myricetin, rutin and apigenin. In vegetables, quercetin glycosides predominate, but glycosides of kaempferol, luteolin, and apigenin are also present. Fruits exclusively contain quercetin glycosides, whereas kaempferol and myricetin glycosides are found only in trace quantities. In this article we mainly discussed on three major flavonols [kaempferol, quercetin, and myricetin] and two major flavones [luteolin and apigenin] of edible tropical plants
ABSTRACT
