年輕素食者與非素食者蛋白質攝取對維生素B6營養狀況的影響
The Effect of Animal and Plant Proteins on Vitamin B6 Status in Young Adult Vegetarians and Nonvegetarians
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.
