在开发和测试旨在改善全球补充喂养的计划时，当地非强化食品解决方案是可预见未来的一项重要战略。这些解决办法对欠发达国家的农村穷人尤其重要。锌是值得注意的个别营养素已被指定为“问题”的营养素，这是很难从补充食品没有强化摄入。本文考虑了肉类+/-肝脏在解决这一明显问题方面的潜在作用。在最近科罗拉多的一项研究中，牛肉和谷物被确定为5-7个月之间作为第一和常规补充食物同样可以接受。平均摄入量和7个月的年龄从牛肉中吸收锌，加上适度的摄入量/吸收的锌从母乳中在这个年龄，足以满足平均饮食和生理锌的需求，分别。考虑到可负担得起的肉类的可接受性和可获得性的障碍，但这些障碍既不是普遍的，也不是所有人群都无法解决的。
In the development and testing of programs designed to improve complementary feeding globally, local nonfortified food-based solutions comprise an important strategy for the foreseeable future. These solutions are especially vital for the rural poor of less-developed countries. Zinc is notable among individual nutrients that have been designated as "problem" nutrients, adequate intake of which is difficult from complementary foods without fortification. This article considers the potential role of meat +/- liver in addressing this apparent problem. In a recent Colorado study, beef and cereal have been determined to be equally acceptable between age 5-7 mo as first and regular complementary foods. Average intake and absorption of Zn from beef by 7 mo of age, together with the modest intake/absorption of Zn from breast milk at that age, were adequate to meet average dietary and physiologic zinc requirements, respectively. Barriers to acceptability and availability of affordable meat are considered, but these are neither universal nor irresolvable in all populations.
