中文摘要 | 本研究主要目的為比較年輕素食者及非素食者蛋白質、維生素B6及其他營養素的攝取量;及探討各項維生素B6生化指標與蛋白質及飲食纖維攝取量的相關性。37位年輕素食者(男性8位;女性29位)及32位非素食者(男性10位;女性22位) 參與本研究,平均年齡為28.9 ±5.5及22.9 ±1.6歲。素食者包括全素者3位、奶素18位、奶蛋素16位,平均吃素年限為5.6年。結果顯示,素食組與非素食組的蛋白質、維生素B6、及維生素B6對蛋白質的比率的平均攝取量並無顯著差異;但素食者與非素食者的維生素B6平均攝取量(素食組:0.94 ±0.45 mg/d;非素食組:1.05 ±0.45 mg/d)顯著低於台灣新版的膳食營養素參考攝取量。素食者血漿磷酸比哆醛濃度(58.5 ±30.9 vs. 85.9 ±35.2 nmol/L;p < 0.001)及尿液比哆排出量(3.09 ±5.37 vs. 3.54 ±2.39 μmol/d;p < 0.05)顯著低於非素食者。不管是素食組,非素食組,或兩組合併(pooled group,n=69) 後的血漿PLP濃度、尿液4-PA排出量皆與總蛋白、動物蛋白、植物蛋白及膳食纖維攝取量無顯著相關性(p > 0.05)。若蛋白質及飲食纖維攝取量並不是太高的情況下,蛋白質攝取量、不同蛋白質來源、及飲食纖維對於維生素B6營養狀況應無顯著影響。 |
英文摘要 | The purpose of this study was to assess the vitamin B6 status of vegetarians and nonvegetarians, and to examine the effects of nutrient factors (protein and fiber) on various indices of vitamin B6 status. Thirty-seven vegetarians (28.9±5.5 y) and 32 nonvegetarians (22.9±1.6y) participated in the study. The vegetarian group included 3 vegans, 18 lacto-vegetarians, and 16 lacto-ovo-vegetarians. These subjects had been following this diet practice for mean of 5.6 years. There was no significant difference in total protein and vitamin B6 intake or the ratio of vitamin B6 to protein (mg/g) between vegetarian and nonvegetarians subjects. The mean total vitamin B6 intake (vegetarians: 0.94±0.45 mg/d; nonvegetarians: 1.05±0.45 mg/d) was lower than that of the new version of the Taiwan Dietary Reference intakes. The vegetarian group showed significantly lower mean plasma pyridoxal 5'-phosphate (PLP) (58.5±30.9 VS. 85.9 ±35.2 nmol/L; p < 0.001) and urinary 4-pyridoxic acid (4-PA) levels (3.09±5.37 vs. 3.54±2.39 μmol/d; p < 0.05) than did the nonvegetarian group. Dietary protein, vitamin B6, or fiber intake was not related to any vitamin B6 status parameters in any individual or pooled groups. Our vegetarians consumed amounts of protein and fiber that were not very high; therefore, protein intake, the source of dietary protein (plant vs. animal), and dietary fiber had no effects on vitamin B6 status parameters. |
