  • Vitamin E has been a generic term for all tocopherol and tocotrienol derivatives. The most active form of vitamin E isoforms in vivo is regarded to be $\alpha$-tocopherol which is the only form defined as vitamin E in the US Food and Nutrition Board, causing controversy over setting dietary reference intake (DRI) of vitamin E. However, most of the countries other than the US maintain the original concept that all isoforms are accepted as vitamin E but with different biopotency. The roles of the isoforms of vitamin E other than $\alpha$-tocopherol have received continuous attention. Among them those of $\gamma$-tocopherol and $\alpha$-tocotrienol have been most studied in comparison with $\alpha$-tocopherol, since $\gamma$-tocopherol comprises major form of vitamin E in many plant seeds and those of the both vitamin E have been implicated in unique physiological functions. This review summarizes findings that have led a better understanding of vitamin E absorption, transport, tissue storage and various functions common and specific to vitamin E isoforms focusing $\alpha$- and $\gamma$-tocopherol as well as tocotrienols. It is expected to help redefining vitamin E and setting its DRI for Koreans.

  • Objectives: Recommended Menu (RM) prepared according to the Target Pattern expected to meet the dietary reference intake (DRI) of nutrients. Nutritional adequacy of RM in 'DRI for Koreans 2015' were analyzed to verify whether such expectation was fulfilled. Methods: Dishes in RM are categorized by 5 food groups, and number and types of dishes for main meal and between-meals were analyzed. The energy and 12 nutrients (protein, dietary fiber, Ca, P, Fe, Na, K, vitamin A, thiamin, riboflavin, niacin and vitamin C) contents in 10 RMs were calculated using the food composition table (CD) in 'DRI for Koreans'. Energy, energy contribution ratio, and nutrient contents in 10 RMs for 18 age groups were evaluated based on the 'DRI for Koreans 2015'. Results: Number of dishes per meal were 4.83, and representative table setting consisted of cooked rice + soup (or stew) +3 side dishes. Energy contents of RM were 75~109% of estimated energy requirement (EER). None of the RM met the DRI of all 12 nutrients examined. Calcium was the most insufficient nutrient. Only 1-2 years' RM met the DRI, all the other RMs did not meet the calcium DRI. Dietary fiber and potassium contents were also insufficient in most RM. In adult male's RM, only 1 nutrient, i.e. calcium did not meet the DRI, but in female adult's RM, 5~6 nutrients did not meet the DRI. Energy contribution ratio of carbohydrate, protein, and fat in RM were 59.0~70.4%, 15.7~17.5%, 12.1~23.5%, respectively. And 4 RMs out of 10 exceeded the upper limit of acceptable macro-nutrient distribution range (AMDR) of carbohydrate and 3 RMs out of 10 RM were below the lower limit of fat AMDR. Contribution ratio of nutrients were ${\geq}40%$ by food groups were as follows: grain group in energy and carbohydrate; meat fish egg legume group in fat, protein, and niacin; vegetables group in dietary fiber, vitamin A, and vitamin C; milk dairy products group in calcium. Conclusions: RM prepared according to the Target Pattern did not meet nutritional adequacy as expected. Especially calcium, potassium, and dietary fiber contents are needed to be increased in many RMs. Further, energy content in RM needs to be adjusted for fat sugar food group assigned in Target Pattern and condiment.

  • Nutritional status and dietary intake play a significant role in the prognosis of breast cancer and may modify the progression of disease. The aim of this study was to determine the influence of nutritional status on the quality of life of Iranian breast cancer survivors. Cross-sectional data were collected for 100 Iranian breast cancer survivors, aged 32 to 61 years, attending the oncology outpatient clinic at Golestan Hospital, Ahvaz, Iran. Nutritional status of subjects was assessed by anthropometric measurements, Patient-Generated Subjective Global Assessment (PG-SGA) and three non-consecutive 24-hour diet recalls. The European Organization of Research and Treatment of Cancer Quality of Life form (EORTC QLQ-C30) was used to assess quality of life. Ninety-four percent of the survivors were well-nourished, 6% were moderately malnourished or suspected of being malnourished while none were severely malnourished. Prevalence of overweight and obesity was 86%. Overall, participants had an inadequate intake of vitamin D, E, iron and magnesium according to dietary reference intake (DRI) recommendations. Survivors with better nutritional status had better functioning scales and experienced fewer clinical symptoms. It appears important to provide educational and nutritional screening programs to improve cancer survivor quality of life.

  • 본 연구는 알코올중독자의 영양지식과 식습관 및 영양섭취상태의 특성을 알아보고, 영양교육이 이들 특성에 미치는 효과를 알아보고자 수행되었다. 알코올중독으로 병원에 입원한 37명 환자를 연구대상자로 하였으며, 이들의 영양지식과 식습관은 설문지를 이용하여 조사하였고, 영양교육은 80분짜리 5차시 분량의 프로그램을 제작해 실시하였다. 본 연구대상자는 40대 중반의 남성이었으며, 정상 체위를 지녔고, 병원에 입원하기 전 음주 빈도가 높고, 음주량이 많으며, 소주를 선호하는 음주습관을 지니고 있었다. 이들은 저 학력, 중 하류층 직업, 독거 비율이 높은 가족형태 등 사회경제적 수준이 열악한 편이었고, 자신의 건상상태에 대한 인식은 낮은 경향이었으며, 간 질환을 비롯한 질병 보유율이 높아, 삶의 질이 취약한 편이었다. 영양교육 실시 전 이들의 영양지식은 1점 만점에 0.52점으로 비교적 낮은 수준이었고, 식습관은 3점 만점에 1.70점으로 바람직하지 않은 경향이었다. 영양섭취상태도 에너지와 식이섬유를 비롯해 본 연구에서 조사한 8종의 비타민 중에 비타민 C, 티아민, 리보플라빈 및 엽산이 영양섭취기준을 충족하지 못했고, 6종의 무기질 중에서는 칼슘과 칼륨은 영양섭취기준에 미치지 못한 반면에 나트륨 섭취는 과다한 문제점을 보였다. 그러나 영양교육을 받은 후 본 연구대상자의 영양지식이 0.81점으로 유의하게 향상되었고, 식습관은 2.13점으로 유의성 있게 개선되었으며, 영양섭취상태도 다음과 같이 유의적으로 향상되었다. 즉 에너지, 탄수화물, 식이섬유, 비타민 E를 제외한 비타민 A, 비타민 C, 비타민 $B_6$, 티아민, 리보플라빈, 엽산 및 니아신, 칼슘, 인, 칼륨, 철분, 아연 모두 섭취가 증가했다. 반면에 나트륨 섭취는 감소했으나 여전히 목표섭취량의 256%에 달하였지만, 감소했으며, 이러한 결과 Na/K 섭취 비율이 저하되었다. 이와 같은 본 연구결과는, 비록 연구대상자가 광주광역시에 소재한 G병원에 입원 중인 소수의 성인남자 환자였다는 제한점은 있으나, 알코올중독 입원환자의 경우 영양지식 정도가 낮고, 식습관이 좋지 않으며, 영양섭취상태가 불량한 편이지만 이들에게 비교적 단기간의 영양교육을 실시함으로써 이러한 문제점들을 긍정적으로 변화시킬 수 있다는 점을 확인해 주었다. 그러므로 알코올중독전문병원 등 알코올중독자의 재활을 돕는 현장에서 영양교육의 필요성을 인식하고 영양교육을 적극 실시하여야 할 것으로 사료된다.
