As a fundamental right, the right to adequate food en-titles everyone to live with dignity by having access to adequate food that is safe and nutritious. However, the current food system features unequal food production and distribution. To remedy this situation, certain concepts have been proposed to realize the right to adequate food, including food security, food safety, food sovereignty, food de-mocracy and food exception. This paper analyses these concepts from the perspective of the right to adequate food and how they can be in-corporated into legislation to help realize and protect this right.
