Abstract

Intake of gamma-aminobutyric acid (GABA) from nutritionally controlled hospital diet was analyzed and compared with those estimated by calculation. Thirty meals provided at a hospital in Okinawa were sampled. GABA content per meal were measured by HPLC and calculated from GABA content data in foods as much as available. As a result, out of a total of 30 meals, only 49.3% of the weight of food that appeared in the meals could be calculated. The analyzed and calculated median daily GABA intake was 67.3 mg and 30.0 mg. Overall, the calculated values were lower than the analytical values, but there was a significant positive correlation (rs=0.618, p<0.001). The more complete the database on GABA content, the more accurate the GABA intake could be estimated by calculation.
