- Abstract
Tempeh is a traditional and nutritious food of Indonesia which contains vitamin B12 and vegetarians have higher risk of vitamin B12 deficiency. The objective was to investigate the effect of tempeh consumption on the level of serum vitamin B12 and homocysteine in vegetarian. Methods: Experimental study with randomized control and double blind. The total samples were 118 vegetarians from Pekanbaru in 2010 consisted of 42 vegetarians with vitamin B12 deficiency treated by vitamin B12 fortification. The 76 normal vegetarians aged above 17 years old were randomly assigned to consume 100g tempeh formula (5.9 µg vitamin B12) daily (n=38) or placebo (n=38). Vitamin B12 in tempeh formula and serum were analyzed by spectrophotometer before and after 3 months intervention, and after retention for 3 months without intervention. Results: Prevalence of vitamin B12 deficiency in lacto-ovo-vegetarian was 35.6%. Delta of serum vitamin B12 after retention for 3 months without intervention was +3.5 pmol/L in tempeh group (p = 0.804) and -19.2 pmol/L in placebo group (p = 0.038). There was a significant correlation between serum vitamin B12 and homocysteine. Conclusion: Tempeh could maintain normal level of serum vitamin B12 after retention for 3 months without intervention in vegetarian.
