Poor nutrition is harmful to one's health as it can lead to overweight and obesity and a number of chronic diseases. Understanding consumer perceptions toward diet and nutrition is critical to advancing nutrition-related population health interventions to address such issues. The purpose of this paper was to examine Canadians' perceived health and diet status, compared to their actual health status, and general concern about their own diet and beliefs about health. Also analyzed were some of the perceived barriers to eating "healthy" foods, with a focus on the availability of "healthy" processed foods.
Two surveys were administered online to a group of Canadian panelists from all ten provinces during May 2010 to January 2011. Thirty thousand were invited; 6,665 completed the baseline survey and 5,494 completed the second survey. Panelists were selected to be nationally representative of the Canadian adult population by age, sex, province and education level, according to 2006 census data.
Approximately one third of Canadians perceived their health or diet to be very good while very few Canadians perceived their health or diet to be very poor. While the majority of Canadians believed food and nutrition to be very important for improving one's health, fewer Canadians were concerned about their own diets. The majority of Canadians reported difficulty finding "healthy" processed foods (low in salt and sugar and with sufficient vitamins and minerals). Many also reported difficulty finding healthy foods that are affordable.
Although consumers believe that nutrition is one of the most important factors for maintaining health, there are still a number of attitudinal and perceived environmental barriers to healthy eating.
营养不良对健康有害,因为它会导致超重、肥胖以及多种慢性疾病。了解消费者对饮食和营养的看法对于推进与营养相关的人群健康干预措施以解决此类问题至关重要。本文旨在研究加拿大人对自身健康和饮食状况的认知与其实际健康状况的对比,以及他们对自身饮食的总体关注和对健康的信念。还分析了一些被认为是食用“健康”食品的障碍,重点关注“健康”加工食品的可获得性。
在2010年5月至2011年1月期间,对来自加拿大所有十个省份的一组受访者进行了两次在线调查。共邀请了3万人;6665人完成了基线调查,5494人完成了第二次调查。根据2006年的人口普查数据,受访者在年龄、性别、省份和教育水平方面被选为具有全国代表性的加拿大成年人群体。
约三分之一的加拿大人认为自己的健康或饮食状况非常好,而极少加拿大人认为自己的健康或饮食状况非常差。虽然大多数加拿大人认为食物和营养对改善健康非常重要,但关注自身饮食的加拿大人较少。大多数加拿大人表示难以找到“健康”加工食品(低盐、低糖且富含足够的维生素和矿物质)。许多人还表示难以找到价格实惠的健康食品。
尽管消费者认为营养是维持健康的最重要因素之一,但健康饮食仍存在一些态度和认知方面的环境障碍。
