Recent findings indicated that rather than amount of energy consumption, type and compositional balance of energy‐deriving nutrients significantly contributes body fat accumulation and consequential diseases. This study was conducted to investigate the status of nutrition intake including fatty acids, lipids and lipid soluble nutrients between obese and lean college students and to analyze the relationship between intake of individual fatty acids from diet and body fat accumulation. Anthropometric assessment including BMI and body composition was performed and a 24hr dietary recall with questionnaires for dietary behaviors was collected for total of 114 Korean college students in Gyeongbuk area. As a result intake of total calorie and total lipids from daily diet were not significantly different between obese and lean subjects in both male and female students. However male obese subjects eat more plant lipids and palmitic acids (C16:0) from their diet (p<0.05) while female obese subjects consumed more linolenic acids (C18:3) compared to lean subjects (p<0.01). Correlation analysis revealed that the consumption of palmitoleic acid (C16:1) and lipid soluble Vitamin D were negatively (p<0.05) correlated with body fat accumulation in all subjects and these findings were supported by simple linear regression analyses for those variables. These results implicate that rather than only considering the amount of lipids, suggesting a proper type of lipids or lipid metabolites can be suggested in nutrition counseling or education. This study was financially supported by a 2013 start‐up grant for junior faculty from Daegu University.
