background: the consumption of low quality foods is common in low socioeconomic areas; and according to epidemiological studies, the density of nutrients often proves the quality of diet. this study aimed to compare the density of macronutrients and micronutrients in various parts of tehran.   methods: this was a cross-sectional study performed from september to december 2007 in all the 22 dist...

gladiolus (gladiolus grandiflorus l.) is one of the most widely cultivated, economically important and common flowering plants worldwide including pakistan. however, its yield of flower is quite low when grown under agro-climatic conditions of multan. a field experiment was conducted at the experimental area, department of horticulture, bahauddin zakariya university, multan (pakistan), during 2...

pumpkin is one the most important cultivated medicinal plants. because of high quality oil it uses as edible and herbal medicine. to find out the effects of different rates of pelleted animal manure and urea levels and some micronutrients on morphophysiological characteristics and oil yield of medicinal pumpkin, a split plot experiment based on rcbd with three replicates was conducted at the re...

Soil macronutrients (P, K, Ca+2 and Mg+2) showed significant differences between the altitudes (P<0.05). Mean soil macronutrients; Mg, P K concentrations were significantly higher at altitude than those lower altitude, whereas mean concentration was altitude. micronutrients, Mn+2, Na, Zn+2, Cl_, Al_ Co also In conclusion, our results indicate that topographical factors, slope aspect in this pre...

The establishment of safe upper intake levels for micronutrients must consider the intake-response relations for both deficiency and toxicity. Limited data are available on the toxicities of most micronutrients, and few studies that meet the criteria considered essential for the risk assessment of other chemicals in food, such as pesticides and food additives, have been performed. In some cases...

beta-Carotene and Retinol Efficacy Trial is a nationwide chemoprevention trial that recruited 18,314 high-risk individuals to test the effect of supplemental beta-carotene and retinol on lung cancer incidence. In this report, we conducted a prospective nested case-control study of the association between serum carotenoids, retinoids, and tocopherols on both lung and prostate cancer incidence. P...

Nutritional deficits in humans and animals constitute a hidden epidemic many impoverished areas across the world. The staple foods of developing South Asian African nations, such as rice, wheat, maize, are poor micronutrients. In recent past, lack food diversification i.e., cereal-based crops low minerals, is another danger to nutritional quality security. Because inherently low-level accumulat...

The aim of the present investigation was to determine the allelopathic effect of aqueous extract from either fresh or oven dried leaves and root of unstressed or water stressed maize plants on soybean growth and its effects on rhizosphere soil treated with maize plant extract. The extracts were applied for 10h to soybean [Glycine max (L.) Merr.] as seed soaking treatment prior to sowing. The ap...

Osteoporosis and low bone mass are currently estimated to be a major public health threat. Adequate nutrition plays a major role in the prevention and treatment of osteoporosis; the micronutrients of greatest importance are calcium and vitamin D. Calcium has been shown to have beneficial effects on bone mass at all ages, although the results are not always consistent. Higher doses than the curr...
