The process of changing food habits is more complex than would appear to most nutritionists; it involves much more than the collection of information. Change must be studied from a multidisciplinary, chiefly a sociologic, point of view, since the food habits of families within a community are formed in a matrix of human relationships. Three major variables are presented and discussed: (a)differentiation, the capacity to process information; (b)accessibility, the measured distance between a family and an information source; and (c)solidarity, the ability of a family group to react cohesively to proposed change. To effect change in his dietary habits, an individual needs his family's cooperation. The nutritionist will do well to rely on the findings of social scientists if proposed changes in family food habits are to be implemented.
改变饮食习惯的过程比大多数营养学家所认为的更为复杂；它所涉及的远不止信息的收集。必须从多学科的角度，主要是社会学的角度来研究改变，因为社区内家庭的饮食习惯是在人际关系的矩阵中形成的。文中提出并讨论了三个主要变量：（a）分化，即处理信息的能力；（b）可及性，即一个家庭与信息源之间的测量距离；（c）团结，即一个家庭群体对提议的改变做出凝聚性反应的能力。要改变个人的饮食习惯，他需要家人的配合。如果要实施家庭饮食习惯的提议改变，营养学家最好依靠社会科学家的研究结果。
