Some reviews of various studies claim that this diet might boost diabetic nephropathy symptoms, which means diabetes-caused kidney destruction. However, the study did not reveal negative diet effects like worsening different diabetic symptoms.
By lowering protein consumption, individuals with kidney problems and not undergoing dialysis can lower kidney stress and inhibit the accumulation of urea in the blood vessels. The body makes urea during protein digestion. In healthy people, urea is eliminated via the urine without complications. Nonetheless, urea accrues in the blood when the kidney malfunctions and results in symptoms like fatigue, suppressed appetite, and nausea. Another study of 17 studies conducted in 2018 found that reduced protein consumption delays the advanced kidney failure progress. Medical doctors recommend that restricting protein intake elongates the period required for dialysis. In this regard, people already undergoing dialysis diagnosis should avoid following an extremely low-protein diet.
This disorder condition is rare and occurs when the body fails to synthesize enzymes required to break down phenylalanine amino acids. For an individual with PKU, consuming protein-rich diets might cause body accumulation of phenylalanine. In case PKU-infected people are not treated, the condition might cause intellectual disability and various neurologic symptoms like seizures, poor coordination, and hyperactivity. The major PKU diagnosis is an extremely low-protein diet. Folks with this condition should take a minimum quantity of phenylalanine essential for development and healthy growth.
