富硒农产品研究开发助力我国营养型农业发展

营养是保证健康的基础。2016年全球疾病负担研究结果显示,饮食因素导致的疾病负担占到15.9%,已成为影响人群健康的重要危险因素。近年来,我国居民营养健康状况明显改善,但仍面临营养不足与过剩并存、营养相关疾病多发等问题,营养与健康已经成为我国食品消费的主流需求。农业生产的根本目标是为了满足居民食物消费需求。作为食品消费最大的供给侧,我国农业现阶段的主要矛盾已经由总量不足转变为结构性矛盾,农业生产如何满足人民对优质食物消费需求的美好向往、适应营养健康需求,已成为推动农业供给侧结构性改革,实现农业现代化发展的首要问题。因此,推动营养型优质农产品生产,是实现农业供给侧改革、满足食品营养健康消费需求的重要途径。硒是机体抗氧化的重要成分,最新营养与健康状况监测显示我国居民硒实际摄入量低于推荐量,研发富硒农产品是满足我国居民食品消费营养健康需求的重要举措。本文结合前期研究基础,从我国居民硒营养基本情况、硒的剂量生物学效应关系两方面介绍了我国富硒农产品开发的依据;并针对我国居民硒摄入量普遍不足现状,概述了我国富硒农产品研发基本情况,最后对我国富硒农业发展提出了相关建议,助力我国营养型农业发展。富硒农产品作为我国营养健康食品发展的重要组成部分,其科学消费观的培养、全产业链的形成、质量监管及标准的制定,对于推动我国营养型农业发展,实现现代农业与食品产业升级,满足人民群众对营养健康的需求、对美好生活的向往具有重要意义。

Promoting the Development of Nutritionally-Guided Agriculture in Research and Development of Selenium-Enriched Agri-Products in China

Nutrition is the guarantee of health. The global burden of disease study in 2016 showed that the disease burden caused by dietary factors accounted for 15.9%, which has become an important risk factor affecting the health of people. In recent years, the nutritional and health status of Chinese residents has been improved significantly, but still faces the coexistence of malnutrition and supernutrition, and the frequent occurrence of nutrition-related diseases. Nutrition and health have become the mainstream demands of food consumption in China. The basic goal of agricultural production is to meet the needs of residents' food consumption. As the biggest supply side of food consumption, the main contradiction in China's agriculture at the present stage has changed from numeric to structural. How to satisfy the people's desire for high-quality food and meet the needs of nutrition and health has become the first issue for agriculture structural reform and modernization. Therefore, promoting the production of nutritious and high-quality agricultural products is an important way to realize the reform of agriculture supply side and to meet the needs of healthy food consumption. Selenium, a key antioxidant component of organisms, its intake is insufficient in Chinese people according to the latest National Nutrition and Health Monitoring Program. Thus, the development of selenium-enriched agricultural products is important for health. In this article, we reviewed the basic information of selenium nutrition concerning the Chinese population, the dose-dependent function of selenium, and the development of selenium-enriched agricultural foods, and also provided some suggestions for selenium-enriched industry development, which might promote the development of nutritionally-guided agriculture. As one of the most important components of nutritional and healthy food development, the application of scientific concepts of consumption, the building of whole-chain production, monitoring and product standard establishment for selenium-enriched agricultural foods are critical for nutritionally-guided agriculture, which will meet the public demand for nutrition and health and also lead to a better life.
