“…The amount of phosphorus contained in food vs. phosphorus absorbed by the body is not always consistent. Given that phosphorus in plant-based foods is often in the form of phytate (which humans have limited ability to digest, given the absence of the phytase enzyme), phosphorus found in plant-based foods usually has lower absorbability and/or bioavailability (20 to 40% bioavailability) compared with animal foods, which often have phosphorus in the form of caseins (40 to 60% bioavailability), and processed foods, in which phosphorus is usually present as food additives (~100% bioavailability) [ 45 , 46 ]. Indeed, both animal and human studies show reduced phosphorus loads when consuming plant-based vs. animal-based diets, despite both diets having the same amounts of phosphorus.…”

There is rising interest globally with respect to the health implications of vegetarian or plant-based diets. A growing body of evidence has demonstrated that higher consumption of plant-based foods and the nutrients found in vegetarian and plant-based diets are associated with numerous health benefits, including improved blood pressure, glycemic control, lipid levels, body mass index, and acid–base parameters. Furthermore, there has been increasing recognition that vegetarian and plant-based diets may have potential salutary benefits in preventing the development and progression of chronic kidney disease (CKD). While increasing evidence shows that vegetarian and plant-based diets have nephroprotective effects, there remains some degree of uncertainty about their nutritional adequacy and safety in CKD (with respect to protein-energy wasting, hyperkalemia, etc.). In this review, we focus on the potential roles of and existing data on the efficacy/effectiveness and safety of various vegetarian and plant-based diets in CKD, as well as their practical application in CKD management.

“…However, exact determination in each food is difficult. Narasaki et al have proposed a novel index reflecting the phosphorus bioavailability: the phosphatemic index (3). It is based on the postprandial increase in serum phosphorus after ingestion of various foods, like the glycemic index.…”

“…It is based on the postprandial increase in serum phosphorus after ingestion of various foods, like the glycemic index. The phosphatemic index can more accurately evaluate the effect of food phosphorus on serum phosphorus levels than the phosphorus/protein ratio or plant food/animal food ratio, and is applicable to evaluation of the dietary phosphorus load and food choices to prevent hyperphosphatemia or an excessive phosphorus load in CKD patients (3).…”

We have adopted the following four topics: 1) dietary phosphorus management in chronic kidney disease (CKD) patients, 2) inadequate nutrient intakes in Filipino schoolchildren and adolescents, 3) clinical and societal implications of vitamin insufficiency, and 4) zinc transporters. Vitamins and minerals play essential roles in health promotion in clinical and societal perspectives with marked advances in understanding the mechanism underlying such effects.

“…Plant-based phosphate occurs in the form of phytates and has lower bioavailability because of a lack of the degrading enzyme phytase in humans [14]. Narasaki Y et al, 2020 [15], reported that low phosphatic index foods (plant-based food) led to decreased PTH, and increased 1,25(OH)2D levels, compared with high phosphatic index foods (animal-based food) with equivalent amounts of phosphate in healthy adults [15]. In addition, additives in processed foods are another source of inorganic phosphate with around 90% bioavailability.…”

Objectives: To assess the dietary phosphate intake of hemodialysis patients with hyperphosphatemia and the effects of a dietetic intervention focused on limiting dietary phosphate load. Design: Cross-sectional dietary phosphate intake assessment and prospective intervention study. Setting: Hospital hemodialysis units of AL-Khor hospital – Hamad Medical Corporation, Qatar. Subjects: sixteen stable adult hemodialysis patients, who had phosphorus serum levels ≥1.6 mmol/L. Intervention: Analysis of dietary composition and of the effects of individual dietetic counseling to reduce phosphorus intake while preserving the same or improving protein intake. Main outcome measures: Differences in nutrient intake between pre and post-dietary intervention among hyperphosphatemia patients, and changes in phosphorus–protein ratio, and serum phosphate, after the dietetic intervention. Results: Significant differences in nutrient intake including energy, protein, and phosphorus were detected after the intervention. After dietetic intervention in the hyperphosphatemia patients, a decrease in the dietary phosphate–protein ratio (28.9 -13.4 mg/g, P <0.05) also occurred. Serum phosphate showed a trend of a significant decrease after the dietary intervention (2.2mmol/L-1.68mmol/L), P < 0.05). Conclusion: Individual intensive nutritional education and counseling may be useful in reducing phosphate load and improving serum phosphorus with a positive effect on nutrient intake. A phosphate-controlled diet has a role in an integrated therapeutic approach to hyperphosphatemia and positive calcium-phosphorus balance in hemodialysis patients.
