INTRODUCTION: The B group vitamins (pyridoxine, riboflavin, cyanocobalamin, folic acid, etc.) are closely related as components of coenzymes involved in energy production processes to perform basic metabolic reactions to the body such as the Krebs cycle The pentose-P cycle, etc ... Vitamin B1 is sometimes dismissed from the list of substances evaluated in a given population, to discard the possible deficiency or alteration in the status of the vitamin. The recommended intake of vitamin B1 in the adult population is 1.1 - 1.2 mg / day1. Severe thiamin deficiency is associated with neurological and cardiac problems while a marginal deficit symptoms and signs common to other diseases that could mask functional. Previous studies show deficiencies of thiamine in about 8% of the population still being studied2. OBJECTIVE: This study assesses the nutritional status of thiamine in a healthy adult population and establishes possible relationships between intake and biochemical parameters, and a deficient status of vitamin B1. METHODS: The study was conducted in a group of people aged between 21 and 59 years, 56 men and 61 women (n = 117). Inclusion criteria were based on the acceptance of subjects to participate in the study and that these subjects did not display any pathology that could affect their nutritional status. Vitamin B1 has been established by coenzyme stimulation technique of the vitamin-dependent enzymes in erythrocyte3. A mild response to stimulation coenzyme indicates the existence of a high enzyme saturaci6n the coenzyme. To determine the intake of vitamin B1 was applied food frequency questionnaire, and through software Nutriber (Mataix, and Garcia Diz, 2006)2, we obtained the% of RDA. It was accepted by the Ethics Committee and informed consent CONCLUSION: Thiamine deficiency is more common than expected in the population, due to unbalanced eating habits and inadequate, being associated with deficiency of other vitamins (B complex). It is therefore advisable to control the status of vitamins B due to alterations in cell functions that occur and the serious consequences which may result.
