Through the study of food policy, it suggested that the level of food security is also related to food waste as well as nutrition and diet. Less food waste is likely to increase food security and food security will ensure the dietary requirement for people from all-ages. Therefore, it is essential to increase consumers’ awareness in reducing food waste to support food waste as well as managing their diet according to the Eatwell Guide. Furthermore, in the hospitality industry, the sector must reduce the level of food waste which will not only support the food security rate in the UK but also improve their financial performance. Nevertheless, by providing a nutritious diet for employees, the hospitality industry is contributing to raising awareness in nutrition and diet issues. Even though there are policies to support each area, the contribution from the hospitality and food service sector is essential.
