Purpose: The purpose of this study was to determine trends in dietary vitamin E intakes and contributing food groups
among Korean adults.
Methods: This study included 66,695 subjects aged ≥ 19 years who completed a nutrition survey as
part of the Korea National Health and Nutrition Examination Survey (1998, 2001, 2005, 2007~2009, 2010~2012, 2013~2015).
We estimated individual daily intakes of α-, β-, γ-, δ-tocopherol, and total vitamin E by linking food consumption data with
a vitamin E database of commonly consumed foods.
Results: Daily vitamin E intake significantly increased from 6.4 mg α-
TE/d in 1998 to 7.7 mg α-TE/d in 2013~2015 (p for trend < 0.0001) among men as well as from 5.4 mg α-TE/d in 1998 to
6.5 mg α-TE/d in 2013~2015 among women (p for trend < 0.0001). However, the intake of vitamin E was lower than the
adequate intake (AI) of Dietary Reference Intakes for Koreans 2015 (2015 KDRI). In 2013~2015, men consumed 6.5 mg/d of
α-tocopherol, 0.5 mg/d of β-tocopherol, 6.0 mg/d of γ-tocopherol, and 3.9 mg/d of δ-tocopherol, whereas women
consumed 5.7 mg/d of α-tocopherol, 0.4 mg/d of β-tocopherol, 4.8 mg/d of γ-tocopherol, and 2.8 mg/d of δ-tocopherol.
The major food groups contributing to vitamin E intake were vegetables (men: 23.3%, women: 22.7%), grains (men: 14.5%,
women: 13.9%), and eggs (men: 13.0%, women: 12.5%).
Conclusion: This study provides scientific evidence for vitamin E
intake in Korean adults. Since the current intake of vitamin E was lower than the reference intakes set by 2015 KDRI, dietary
vitamin E intake should be monitored regularly among Korean adults.
