Core Viewpoint - The promotion of whole grains is transitioning from advocacy to systematic implementation, with a focus on integrating whole grain foods into daily diets through institutional canteens, thereby enhancing public dietary structure and nutrition [1][3]. Group 1: Whole Grains Benefits - Whole grains are described as natural "nutrient packages" that retain essential components such as bran, germ, and endosperm, providing dietary fiber, micronutrients, and bioactive substances [1]. - Current consumption of whole grains in China is less than 1% of total grain consumption, indicating a significant gap in dietary structure [1]. Group 2: Challenges in Promotion - There are systemic mismatches between whole grain foods and mainstream dietary habits, including sensory experience, processing compatibility, and consumer inertia [2]. - Whole grains have a rougher texture and shorter shelf life due to their oil content, which contrasts with the long-established preference for refined grains [2]. - The lack of a mature supply chain and processing technology for whole grains leads to higher prices and limited consumer adoption [2]. Group 3: Strategic Implementation in Canteens - Utilizing canteens as a promotion platform can effectively address challenges by reaching a large audience and reducing costs through centralized purchasing and subsidies [3]. - Canteens can create a "default option" for whole grains, helping consumers gradually adapt to their taste and integrate them into their diets [3]. - The standardized processes in canteens allow for better adaptation of cooking techniques to improve the taste and nutritional quality of whole grain products [3]. Group 4: Long-term Dietary Change - The transition to whole grains requires a gradual approach, allowing consumers to adapt their taste preferences over time [4]. - Continuous innovation in cooking techniques and ingredient combinations is essential to enhance the flavor of whole grains [4]. - Educational initiatives in canteens can help consumers understand the nutritional benefits of whole grains, fostering a cultural shift towards healthier eating habits [4].
