Taste intensity to 6-n-propylthiouracil (PROP) has been demonstrated to affect food acceptance and food intake. Because most PROP status research has been performed among predominantly white subjects, research is needed to test the effects of PROP taste intensity on food acceptance and body weight among racial minorities. This study was conducted to examine racial differences in the effect of PROP taste intensity and food liking on body mass index between African Americans and Asian Americans. A cross-sectional design with a sample of 50 African Americans (25 women, 25 men) and 50 Asian Americans (23 women, 27 men) in the New York City area aged 18 to 55 years was used in this study.
