The subject of this article is the issue of short food supply chains. The research problem formulated in the paper aims to address whether short food supply chains ensure the sustainable development of rural areas and whether they are being displaced by longer chains for narrowly defined economic reasons. The research was conducted based on a critical analysis of literature on short food supply chains and statistical data. The findings of the research indicate that short food supply chains are a necessary condition for the sustainable development of rural areas. Unfortunately, there is a conflict between the pursuit of narrowly defined economic efficiency of farms and the preservation of the social potential of rural areas, which stems from the fact that the principle of price competition does not favor the development of local supply markets, especially when it comes to high-quality food.
