BACKGROUND/OBJECTIVES: Vitamin E is a fat-soluble vitamin and functions primarily as a lipid antioxidant. Inadequate vitamin E status may increase risk of several chronic diseases. Thus, the objectives of this study were to estimate intake and plasma concentration of each tocopherol and to evaluate vitamin E status of Korean adults.
SUBJECTS/METHODS: Three consecutive 24-h food recalls and fasting blood samples were collected from healthy 20- to 59-y-old adults (33 males and 73 females) living in the Seoul metropolitan area, South Korea. α-, β-, δ-, and γ-tocopherol intakes and plasma concentrations of tocopherols (α-, δ-, and γ- tocopherol) were analyzed by gender.
RESULTS: Dietary vitamin E and total vitamin E intake (dietary plus supplemental vitamin E) was 17.68 ± 14.34 and 19.55 ± 15.78 mg α-tocopherol equivalents, respectively. The mean daily α-tocopherol, and γ-tocopherol intakes were 3.07 ± 2.27 mg and 5.98 ± 3.74 mg, respectively. Intakes of total vitamin E and each tocopherol of males were significantly higher than those of females (P < 0.05). Plasma α-tocopherol concentration was 15.45 ± 10.16 of males and 15.00 ± 4.54 μmol/L of females, respectively. There were no significant differences in plasma tocopherol concentrations by gender (P ≥ 0.05). Plasma α-tocopherol was negatively correlated with γ-tocopherol intake (P < 0.05). Twenty-three percent of the subjects had plasma α-tocopherol concentrations < 12 μmol/L indicating a biochemical deficiency of vitamin E. Approximately 8% and 9% of these participants had plasma α-tocopherol:total lipid ratio less than 1.59 μmol/mmol and plasma α-tocopherol:total cholesterol ratio less than 2.22 μmol/mmol, respectively, which are also indicative of vitamin E deficiency.
CONCLUSIONS: Vitamin E intakes of Korean adults were generally adequate with the Korean Dietary Reference Intakes for vitamin E. However, α-tocopherol intake was lower than that reported in other countries, and 23% of the subjects in the current study were vitamin E deficient based on plasma α-tocopherol concentrations.
