Primary Outcome Measures:
  • mortality or using dialysis [ Time Frame: 4-years ]

Enrollment: 41
Study Start Date: April 2001
Study Completion Date: September 2005
Arms Assigned Interventions
Experimental: 1 Dietary Supplement: Soy protein
35 % of protein from soy protein for 4-years

Detailed Description:

Background: Several short-term trials on the effect of soy consumption on cardiovascular risks are available, but little evidence exists regarding the impact of long-term soy protein consumption among type 2 diabetic patients with nephropathy.

Objectives: To determine the effects of long-term soy consumption on cardiovascular risks, C-reactive protein and kidney-function indices among type 2 diabetic patients with nephropathy.

Design: This longitudinal randomized clinical trial was conducted among 41 type 2 diabetic patients with nephropathy (18 men and 23 women). Twenty patients in soy protein group consumed a diet containing 0.8 g protein/kg body weight (35% animal proteins, 35% textured soy protein, and 30% vegetable proteins) and 21 patients in control group consumed a similar diet containing 70% animal proteins and 30% vegetable proteins for 4-years.
