One of the most important main environmental problems is soil erosion and its affects. Eutrophication, low oxygen levels and `high nutrient (nitrogen and phosphorus) concentrations in reservoirs, channel and other water courses, is a common water pollution feature. Phosphorus (P) is one of the major plant nutrients and also the major nutrients controlling eutrophication of surface water. The ai...

Background and purpose: The rate of carbohydrate absorption after a meal, as quantified by glycemic index, has an effect on postprandial hormonal and metabolic response. The aim of the present study is to determine the effects of low-glycemic index diet, versus low-fat diet on the body weight, BMI, WHR (waist/hip ratio) and plasma lipid profile of obese patients. Materials and methods: ...
