Older Adults' Awareness and Knowledge of Beans in Relation to Their Nutrient Content and Role in Chronic Disease Risk

Abstract

Awareness and knowledge of nutrient-dense foods are important for older adults to help them make dietary choices that support a food-first approach to healthy aging. This is especially important since age is a major risk factor for chronic disease and the proportion of older adults in North America is increasing. Beans can contribute to a food-first approach to healthy aging as they are nutrient-dense and can reduce the risk of chronic diseases. However, studies exploring awareness and knowledge of beans in older adults are lacking. Therefore, the aim of this study was to explore older adults' awareness of beans in relation to their nutrient content and role in chronic disease risk. Community-dwelling older adults (≥65 years old) were recruited and completed a validated researcher-administered questionnaire (n = 250), which was followed by 10 focus groups (n = 49). Results showed that the majority of older adults considered beans as a healthy food and thought consuming them could improve their health (99.2% and 98.0%, respectively); however, only 51.2% were bean consumers. While the majority (83.6%) of older adults were aware that a serving of beans is high in dietary fibre, bean consumers were significantly more likely to think that consuming beans could improve health areas related to dietary fibre including body weight management and constipation. Furthermore, most (84.8%) older adults thought consuming beans could improve heart health; however, bean consumers were significantly more likely to be aware that one serving of beans is low in nutrients relevant to heart health including total fat, saturated and trans fat as well as cholesterol. This research can help to inform healthcare professionals and public health agencies to create specific dietary strategies focusing on increasing older adults' awareness and knowledge of beans in relation to their nutrient profile and role in promoting health.
