Environmentally sustainable diets are increasingly aspired to in food-based dietary guidelines across the world. However, little is known about consumer attitudes toward these diets when making food decisions. This study aimed to identify the demographic characteristics of Australian adults based on the level of attention they paid to the healthfulness of their diet, their consideration of the level of food processing, and their concern about household food waste and sustainable packaging disposal. Adults aged from 18 to over 75 years (n = 540) were surveyed online. Thirty-seven percent were concerned about sustainable food waste, 28% considered the level of food processing when making food decisions, and 23% paid attention to the healthfulness of the food they ate. Adults who had higher educational attainment (above Year 12) were twice as likely to be concerned about food waste and sustainable packaging disposal (odds ratio (OR) = 2.10, 95% confidence interval (CI) 1.29-3.4), and processing levels (OR = 2.04, 95% CI 1.23-3.42) (controlling for age and gender). Those earning an income over AUD$100,000 were twice as likely to pay attention to the healthfulness of their food choices than those earning less than AUD$50,000 (OR = 2.19, 95% CI 1.28-3.74). Only 9% percent were concerned about or paid attention to all three of the components of healthy sustainable diets investigated, and 45% paid no attention and were not concerned about all three components. These findings suggest there is a need to educate the public to raise awareness of and concern for healthy, minimally processed, and sustainable food choices.
在全球范围内，基于食物的膳食指南越来越倾向于环境可持续的饮食。然而，在做出食物决策时，消费者对这些饮食的态度知之甚少。本研究旨在根据澳大利亚成年人关注饮食健康程度、考虑食物加工水平以及关注家庭食物浪费和可持续包装处理的程度，确定他们的人口统计学特征。年龄在 18 岁以上 75 岁以下的成年人（n = 540）在线接受调查。37%的人关注可持续的食物浪费，28%的人在做出食物决策时考虑食物加工水平，23%的人关注所吃食物的健康程度。受教育程度较高（高于 12 年级）的成年人更关注食物浪费和可持续包装处理（优势比（OR）= 2.10，95%置信区间（CI）1.29-3.4）和加工水平（OR = 2.04，95% CI 1.23-3.42）（控制年龄和性别）。收入超过 100,000 澳元的成年人比收入低于 50,000 澳元的成年人更关注食物选择的健康程度（OR = 2.19，95% CI 1.28-3.74）。只有 9%的人关注或关注所调查的健康可持续饮食的所有三个组成部分，而 45%的人不关注也不关注所有三个组成部分。这些发现表明，需要对公众进行教育，以提高对健康、低加工和可持续食物选择的认识和关注。
