Describe beliefs about what makes foods healthful among low-income African American women.
In one-on-one interviews, 28 low-income African American mothers viewed 30 pairs of familiar foods and explained which food in the pair was more healthful and why. Responses were grouped into codes describing concepts of food healthfulness.
Nutrient content, physical effects of food, and food categories were used to judge the healthfulness of foods. Fruits, vegetables, and dairy foods were considered the most healthful and starchy foods the least healthful because they were believed to cause weight gain. Beliefs about which foods contain which nutrients and which foods have particular physical effects varied widely across participants.
Participants demonstrated awareness of which foods are healthful but lacked understanding of why those foods are more healthful than others. Knowledge about the health effects of foods may be necessary to motivate individuals to choose healthful foods.
描述低收入非裔美国女性对哪些食物有益健康的看法。
在一对一的访谈中，28 位低收入非裔美国母亲观看了 30 对熟悉的食物，并解释了哪对食物中的食物更健康，以及为什么。将回答分成描述食物健康概念的代码。
营养成分、食物的物理作用和食物类别被用来判断食物的健康程度。水果、蔬菜和奶制品被认为是最健康的，而淀粉类食物是最不健康的，因为它们被认为会导致体重增加。参与者对哪些食物含有哪些营养成分以及哪些食物有特定的物理作用的看法差异很大。
参与者表现出对哪些食物有益健康的认识，但缺乏对为什么这些食物比其他食物更健康的理解。了解食物对健康的影响可能是激励个人选择健康食物的必要条件。
