NOVA is a food-classification system based on four levels of processing, from minimally processed to ultra-processed foods (UPFs). Whole-grain-containing commercial breads and ready-to-eat breakfast cereals are considered ultra-processed within NOVA, despite being considered core foods in the Australian Dietary Guidelines. These food categories contribute the greatest quantities of whole grain in the Australian diet, although consumption is less than half of the 48 g/day daily target intake. Dietitians are key to disseminating messages about nutrition and health; therefore, an accurate understanding of whole grains and the effects of processing is critical to avoid the unnecessary exclusion of nutritionally beneficial foods. The aim was to utilise an online structured questionnaire to investigate dietitians' attitudes to the promotion of grains and whole grains and understand their level of knowledge about and attitudes towards NOVA and the classification of specific whole-grain foods. Whole-grain foods were perceived positively and are regularly promoted in dietetic practice ( = 150). The dietitians tended not to consider whole-grain breads and ready-to-eat breakfast cereals as excessively processed, although most generally agreed with the classification system based on the extent of processing. If dietitians intend to incorporate NOVA and concepts of UPFs in their counselling advice, the anomalies regarding the categorisation of whole-grain choices and optimum intakes should be addressed.
NOVA 是一种基于四个加工层次的食品分类系统,从最低限度加工到超加工食品(UPF)。尽管全麦商业面包和即食早餐麦片被认为是澳大利亚饮食指南中的核心食品,但在 NOVA 中被归类为超加工食品。这些食品类别在澳大利亚饮食中提供了最大量的全麦,但摄入量不到每日目标摄入量 48 克的一半。营养师是传播营养和健康信息的关键;因此,准确了解全谷物和加工的影响对于避免不必要地排除有营养的食物至关重要。目的是利用在线结构化问卷调查营养师对谷物和全谷物推广的态度,了解他们对 NOVA 和特定全谷物食品分类的知识水平和态度。全谷物食品在饮食实践中得到了积极的认可和定期推广(=150)。营养师们倾向于不认为全麦面包和即食早餐麦片是过度加工的,尽管大多数人普遍同意基于加工程度的分类系统。如果营养师打算在他们的咨询建议中纳入 NOVA 和 UPF 的概念,那么应该解决全谷物选择和最佳摄入量分类方面的异常问题。
