Dietary advice that promotes optimal nutrition presupposes adequate land for growing food, environmental quality conducive to food production, stable government, a strong economy, and community food security (or a reliable transportation system). Without these conditions, recommendations for optimal nutrition become moot. Our profession will be strengthened as we develop a broad knowledge of our entire food system.
促进最佳营养的饮食建议预先假定有足够的土地用于种植粮食、有利于粮食生产的环境质量、稳定的政府、强大的经济以及社区粮食安全（或可靠的运输系统）。没有这些条件，关于最佳营养的建议就变得毫无意义。随着我们对整个粮食系统有更广泛的了解，我们的专业将得到加强。
