Consumer demand for plant-based foods is increasing though the reasons may vary. Plant foods are sole sources of dietary fiber, vitamin C, and flavonoids and good sources of vitamin B1, folic acid, potassium, and magnesium. They are low in saturated fat, and do not contain cholesterol and vitamin B12. Plant foods are associated with better body weight and healthy blood lipid profile. This cross-sectional study used nationally representative National Health and Nutrition Examination Survey 2013-2016 data and compared nutrient and food pattern food group intakes of adults eating a vegetarian-style diet with adults eating a nonvegetarian diet. Adults 20+ years ( = 10,064) were grouped using the Dietary Guidelines for Americans 2015-2020 definition of vegetarian-style diet, which is modelled as lacto-ovo-vegetarian diet. Trained dietary interviewers collected self-reported dietary intake data using a 24-h recall and an automated multi-pass method. Means were compared using linear contrasts ( < 0.01). On average, the vegetarians ate an estimated 419 fewer kilocalories, 7 g less saturated fat, and 1274 mg less sodium. The vegetarian-style diet was higher in micronutrient density, except for vitamin B12 and zinc. The vegetarians ate more whole grains, legumes, nuts, and soy products. Fruit, vegetables, and dairy intakes were similar for both groups. A vegetarian-style diet may be advocated to control energy, saturated fat, and sodium intakes.
消费者对植物性食品的需求正在增加,尽管原因可能各不相同。植物性食品是膳食纤维、维生素 C 和类黄酮的唯一来源,也是维生素 B1、叶酸、钾和镁的良好来源。它们的饱和脂肪含量低,不含胆固醇和维生素 B12。植物性食品与更好的体重和健康的血脂谱有关。本横断面研究使用具有全国代表性的 2013-2016 年全国健康和营养调查数据,比较了食用素食和非素食的成年人的营养素和食物模式食物组的摄入量。20 岁及以上的成年人(n=10064)根据美国 2015-2020 年饮食指南中素食的定义进行分组,该定义模拟为乳蛋素食。经过培训的饮食调查员使用 24 小时回忆和自动多遍法收集自我报告的饮食摄入数据。使用线性对比(<0.01)比较平均值。平均而言,素食者摄入的热量估计减少了 419 千卡,饱和脂肪减少了 7 克,钠减少了 1274 毫克。素食模式的饮食中微量营养素密度更高,除了维生素 B12 和锌。素食者摄入更多的全谷物、豆类、坚果和豆制品。两组的水果、蔬菜和奶制品摄入量相似。提倡素食模式的饮食可能有助于控制能量、饱和脂肪和钠的摄入量。
