During the complementary feeding period, children require a nutrient-dense diet to meet their high nutritional requirements. International interest exists in the promotion of affordable, nutritionally adequate complementary feeding diets based on locally available foods. In this context, two questions are often asked: 1) is it possible to design a diet suitable for the complementary feeding period using locally available food? and 2) if this is possible, what is the lowest-cost, nutritionally adequate diet available? These questions are usually answered using a "trial and error" approach. However, a more efficient and rigorous technique, based on linear programming, is also available. It has become more readily accessible with the advent of powerful personal computers. The purpose of this review, therefore, is to inform pediatricians and public health professionals about this tool. In this review, the basic principles of linear programming are briefly examined and some practical applications for formulating sound food-based nutritional recommendations in different contexts are explained. This review should facilitate the adoption of this technique by international health professionals.
在辅食添加期，儿童需要营养丰富的饮食来满足其较高的营养需求。国际上关注推广基于当地可得食物的经济实惠且营养充足的辅食添加饮食。在此背景下，人们常问两个问题：1）是否有可能利用当地可得食物设计出适合辅食添加期的饮食？2）如果可行，成本最低且营养充足的饮食是什么？这些问题通常采用“反复试验”的方法来回答。然而，也有一种基于线性规划的更高效、更严谨的技术。随着功能强大的个人电脑的出现，它已变得更容易获取。因此，本综述的目的是向儿科医生和公共卫生专业人员介绍这一工具。在本综述中，简要探讨了线性规划的基本原理，并解释了在不同情况下制定合理的基于食物的营养建议的一些实际应用。本综述应有助于国际卫生专业人员采用这一技术。
