Table 2 Changes in plasma levels of homocysteine, cysteine, and cysteinylglycine from baseline to week 12 in overweight men who consumed a CRD.

From: Effects of a carbohydrate-restricted diet on emerging plasma markers for cardiovascular disease

Parameter Baseline Week 12 P Value (Time)
Homocysteine (μmol/L)    
Fiber 8.1 ± 1.2 8.6 ± 2.2 > 0.05
Placebo 8.1 ± 1.4 8.3 ± 1.5 > 0.05
Cysteine (μmol/L)    
Fiber 264.4 ± 34.1 258.9 ± 45.3 > 0.05
Placebo 269.0 ± 30.5 266.2 ± 40.7 > 0.05
Cysteinylglycine (μmol/L)    
Fiber 30.3 ± 5.1 29.9 ± 4.5 > 0.05
Placebo 30.9 ± 3.8 29.0 ± 5.5 > 0.05
  1. Data are presented as means ± SD for the fiber group (n = 14) and the placebo group (n = 14). P values refer to the difference between baseline and week 12. No significant time or treatment effects were observed in any measured plasma marker of homocysteine metabolism. Subjects supplemented the CRD by consuming a standard multivitamin every-other day.
