Five sources of dietary fibre
Hemodialysis, a process to filter wastes and water from the blood of kidney disease patients, can eliminate only 30 per cent of indoxyl sulfate and p-cresyl sulfate, protein-bound uremic toxins produced by intestinal bacteria, according to experts. Therefore, they said there’s a need for additional strategies to reduce uremic toxins, noted Dr Xiao-Hua Wang, PhD, of The First Affiliated Hospital of Soochow University in Suzhou, China, and colleagues. In a study published in the Journal of Renal Nutrition, the research team has suggested that dietary fibre supplements may help reduce uremic toxins in patients with chronic kidney disease (CKD). The study involving 292 CKD patients found that those supplemented with dietary fibre had their serum levels of indoxyl sulfate, p-cresyl sulfate, blood urea nitrogen, and uric acid significantly reduced on dialysis compared with placebo or another control. Dietary fibre supplementation also led to a significant serum creatinine reduction in patients without diabetes compared with controls. Individuals with diabetes may have greater creatinine production as they consume more protein, the researchers noted. However, they found no significant differences between fibre supplement dosage or intervention time. Health experts also recommend every individual to consume about 14 grams of fibre for every 1,000 calories you consume daily. This means women should be having about 25 grams of fibre per day, while men should target about 38 grams. Below are five sources of dietary fibre, but consult your doctor before adding them to your diet.
