Folate is a water-soluble vitamin B group that is found in common foods such as green and yellow vegetables, fruits, and beans. Folic acid deficiency in pregnant women increases the risk of developing neural tube defects in the fetus. The purpose of this study is to investigate the relationship between serum folate concentration, nutrient intake, and intake of foods rich in folate (asparagus, sunny lettuce) in female university students. The female students’ daily folate intake of 380 ± 46 μg was higher than the 226 ± 129 μg intake of women aged 20-29 in the 2019 National Health and Nutrition Survey. Serum folate concentrations before and after asparagus intake were significantly increased before and after 3 weeks of intake (p < 0.01) and after 1 week and 3 weeks of intake (p < 0.05). There was no difference in serum folate concentrations before and after intake of sunny lettuce. To effectively increase serum folate concentrations, continued intake of folate-rich foods with reduced cooking losses are recommended and nutritional education.
