背景资料：膳食维生素和矿物质是代谢酶正常运作、调节基因转录和为身体防御氧化应激提供动力的必需化合物。本研究的目的是调查微量营养素消费分别按年龄和性别，主要膳食来源，并根据意大利（Livelli di Assunzione di Riferimento di Nutrienti（LARN））和欧洲（欧洲食品安全局（EFSA））机构的建议要求的个人的百分比。研究方法：数据来自地中海健康饮食、老龄化和生活方式（MEAL）研究，其中包括在意大利南部卡塔尼亚市随机收集的1838名个体样本。使用经验证的食物频率问卷收集饮食信息。结果如下：维生素A、维生素C和维生素B组（维生素B9除外）的摄入量与其他报告一致，根据指南是足够的，而符合维生素D、维生素E和维生素B9指南的个体百分比分别约为3%、10%和40%。在矿物质中，铁、镁和硒的摄入量对大多数样本来说是足够的，而符合钙、钠和钾摄入量建议的个体比例分别约为20%、8%和35%。结论：很大一部分人口将受益于提高对微量营养素缺乏或过度消费可能影响其健康的认识的运动。
Background: Dietary vitamins and minerals are essential compounds for the proper functioning of metabolic enzymes, regulation of gene transcription, and powering the body's defense against oxidative stress. The aim of the present study was to investigate micronutrient consumption separately by age and sex, major dietary sources, and percentage of individuals meeting the recommended requirements according to Italian (Livelli di Assunzione di Riferimento di Nutrienti (LARN)) and European (European Food Safety Agency (EFSA)) agencies. Methods: Data were obtained from the Mediterranean Healthy Eating, Ageing, and Lifestyle (MEAL) study, which included a sample of 1838 individuals randomly collected in the city of Catania, southern Italy. A validated food frequency questionnaire was used to collect information on diet. Results: Intake of vitamin A, vitamin C, and vitamin B group (except vitamin B9) was in line with other reports and was adequate according to the guidelines, while the percentage of individuals meeting the guidelines for vitamin D, vitamin E, and vitamin B9 was about 3%, 10%, and 40%, respectively. Among minerals, intake of iron, magnesium, and selenium was adequate for most of the sample, while the percentage of individuals meeting the recommendations for calcium, sodium, and potassium intake was about 20%, 8%, and 35%, respectively. Conclusions: An important percentage of the population would benefit from campaigns raising awareness of micronutrient deficiency or excessive consumption potentially affecting their health.
