We have conducted the study about the effects of normal diet and low-phosphorus diet on phosphorus homeostasis in healthy subjects, now this study is designed to explore further about the effect of high-phosphorus diet on phosphorus homeostasis.
Serum phosphate concentrations are not only associated with cardiovascular and all-cause mortality in chronic kidney disease (CKD) patients, but also associated with the mortality in community population. Thus, maintaining normal serum phosphate and reducing postprandial fluctuation of serum phosphate are essential for healthy people.
We have conducted a study about the effects of normal diet (phosphorus 1500mg) and low-phosphorus diet (phosphorus 500mg) on phosphorus homeostasis in healthy men. The results showed low-phosphorus diet could significantly reduce serum phosphorus and urine phosphorus level compared to normal diet. However, the levels of serum FGF23 and a-klotho were not different between these two groups.Thus, we want to further explore the effects of high-phosphorus diet (phosphorus 2300mg)on phosphorus homeostasis in healthy men.
Therefore, the investigators plan to conduct a crossover clinical study to evaluate the phosphorus homeostasis modulated by native normal diet, restricted phosphorus diet, high phosphorus diet and then to explore the underlying mechanisms.

This study evaluates the effect of phosphorus supplementation on the human metabolome. The investigators will do so by conducting a cross-over study in healthy adults consuming a study die...
This pilot study aims to develop a method for simultaneous whole-body calcium and phosphorus balance and full kinetic modeling of both ions in patients with chronic kidney disease.
The aim of the trial is to investigate the effect of ingestion of 75g of glucose (with or without phosphorus) on diet induced thermogenesis (using indirect calorimetry) and appetite (using...
The purpose of this study is to determine the effects of different amounts of phosphorus in the diet on hormones that control phosphorus and bone health both in men who are healthy and in ...
Phosphorus is a substance in the blood that comes from food and is normally cleared from the body by the kidneys. In patients with kidney disease, excess phosphorus may build up in the bod...
In humans, the effects of lysine-fortified wheat on growth measures was much lower than that of animal experimentations that used phosphorus-containing mineral mix. It is known that wheat contains a l...
Hyperkalemia and hyperphosphatemia are common metabolic disturbances in chronic kidney disease. Management may include instructions on a low-potassium or low-phosphorus diet, respectively. Low-phospho...
The New Nordic Diet is a food concept favouring organically produced food items, fruits, vegetables, whole grains and fish. We investigated the short-term effects of a modified phosphorus-reduced New ...
This study was conducted to determine the effects of residual superdoses of phytase on growth performance, tibia mineralization, and relative organ weight in ducks fed phosphorus-deficient diets. In E...
Continuous feeding of a combined high-fat and high-sucrose diet, rather than an individual high-fat or high-sucrose diet, rapidly enhances the glucagon-like peptide-1 secretory response to meal ingestion in diet-induced obese rats.
Glucagon-like peptide-1 (GLP-1) is secreted by enteroendocrine L-cells in response to nutrient ingestion. To date, GLP-1 secretion in diet-induced obesity is not well characterized. We aimed to examin...
A diet that contains limited amounts of CARBOHYDRATES. This is in distinction to a regular DIET.
Regular course of eating and drinking adopted by a person or animal. This does not include DIET THERAPY, a specific diet prescribed in the treatment of a disease.
Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.
A diet that contains limited amounts of fat with less than 30% of calories from all fats and less than 10% from saturated fat. Such a diet is used in control of HYPERLIPIDEMIAS. (From Bondy et al, Metabolic Control and Disease, 8th ed, pp468-70; Dorland, 27th ed)
A course of food intake that is high in FATS and low in CARBOHYDRATES. This diet provides sufficient PROTEINS for growth but insufficient amount of carbohydrates for the energy needs of the body. A ketogenic diet generates 80-90% of caloric requirements from fats and the remainder from proteins.
