For example, in a study of 239 people with advanced CKD, it was shown that vegetarian diets with very low protein contents (dietary protein intake of 0.3 g/kg/day) supplemented with keto analogues provided satisfactory nutritional status (i.e., BMI and serum albumin levels remained stable over a mean duration of 29.6 months) [70]. This evidence concerns the gene ALB and chronic kidney disease.
