The popularity of plant-based and vegan diets has grown in recent years. While following a vegan diet has been associated with various health benefits, the intake of certain vitamins and minerals including vitamins B12 and D, calcium, and iron, are likely to be inadequate in an exclusively plant-based diet. Low nutrient intake over time can lead to nutritional deficiencies and potentially increased risk of adverse health outcomes. In this study, we analyzed a one-week meal plan comprised of vegan recipes from Forks Over Knives (FOK), an organization that promotes a low-fat, whole-food, vegan diet to prevent or reverse chronic disease. A detailed analysis of the meal plan found that it was deficient in several nutrients. It did not meet at least 90% of the daily value (DV) for the following: biotin (56% DV), calcium (58% DV), choline (30% DV), iodine (1% DV), niacin (75%), selenium (68%), vitamin B12 (82% DV), vitamin D (5% DV), vitamin E (7% DV), and zinc (64% DV). Based on evidence from this analysis, vegans and their healthcare providers should be aware of potential nutrient deficiencies and health consequences that may result from this type of diet.
近年来，以植物为基础的纯素饮食越来越受欢迎。虽然遵循纯素饮食与多种健康益处相关，但在纯素饮食中，某些维生素和矿物质的摄入量可能不足，包括维生素B12、维生素D、钙和铁。随着时间的推移，营养素摄入量低会导致营养缺乏，并可能增加不良健康后果的风险。在本研究中，我们分析了一份为期一周的饮食计划，该计划由“餐叉胜于手术刀”（FOK）组织提供的纯素食谱组成，该组织倡导低脂、全食物、纯素饮食以预防或逆转慢性病。对该饮食计划的详细分析发现，它缺乏几种营养素。以下营养素的摄入量未达到每日摄入量（DV）的至少90%：生物素（56%DV）、钙（58%DV）、胆碱（30%DV）、碘（1%DV）、烟酸（75%）、硒（68%）、维生素B12（82%DV）、维生素D（5%DV）、维生素E（7%DV）和锌（64%DV）。基于该分析的证据，纯素者及其医疗保健提供者应意识到这种饮食类型可能导致的潜在营养素缺乏和健康后果。
