Summarize this article for a 10 year old
A food desert is an area that has limited access to food that is plentiful, affordable, or nutritious.[1][2][3] In contrast, an area with greater access to supermarkets and vegetable shops with fresh foods may be called a food oasis.[4] The designation considers the type and the quality of food available to the population, in addition to the accessibility of the food through the size and the proximity of the food stores.[5]

In 2017, the United States Department of Agriculture reported that 39.5 million people or 12.8% of the population were living in low-income and low-access areas.[6] Of this number, 19 million people live in "food deserts", low-income census tracts that are more than one mile from a supermarket in urban or suburban areas and more than 10 miles from a supermarket in rural areas.[6][7]
Food deserts tend to be inhabited by low-income residents with inadequate access to transportation, which makes them less attractive markets for large supermarket chains.[8][9] These areas lack suppliers of fresh foods, such as meats, fruits, and vegetables. Instead, available foods are likely to be processed and high in sugar and fats, which are known contributors to obesity in the United States.[10]
A related concept is the phenomenon of a food swamp, a recently coined term by researchers who defined it as a disproportionate number of fast food restaurants and advertising to a supermarket.[11] The single supermarket in a low-income area does not, according to researchers Rose and colleagues, necessitate availability nor does it decrease obesity rates and health risks.[11]
