    Many of the serious health concerns in modern America can be linked to poor diet．People who regularly consume foods high in salt, sugar, and fats not only increase their chances of being overweight, but also increase their risks of developing diseases. Although some people who regularly consume unhealthy foods do so knowingly, there are also some people that remains undereducated about proper nutrition( 营 养 ). What is more, people who live in food deserts—areas in low-income(低收入) neighborhoods that lack easy access(路径) to healthy, affordable food—may not even have the opportunity to get nutritious food.

Food deserts are located in low-income areas and most often develop when major supermarket chains either move out    of these areas or simply avoid building stores there in the first place. These supermarket chains tend to limit their store locations to richer urban or suburban neighborhoods．This means that those who live in low-income areas often live miles away from the fresh meats and dairy products available at supermarkets. People of these areas are thus forced to travel long distances to do their grocery shopping, or else they are limited to the food available at local convenience stores. These stores often only sell packaged, processed foods that offer little nutrition.

Furthermore, there are too many fast food restaurants in low-income areas; recent research suggests that those living in the poorest areas of a city experience 2.5 times more exposure to fast food restaurants than people in the richest areas of the city. Because people who live in  food deserts often get their meals from fast food restaurants or convenience stores, they suffer from a variety of health problems．Research has found that people who live in low-income neighborhoods are much more likely to develop healthy problems than those who live in richer neighborhoods.

Of course, it seems obvious that more supermarkets should be built in low-income neighborhoods. But in fact, it is difficult to attract supermarket chains into poor areas because poorer people have less money to spend on food. One way that the government can help to solve this problem is by offering tax breaks or other inspiring policies for supermarkets in low-income areas. In 2010, the Obama administration started the Healthy Food Financing program, which is designed to help bring grocery stores into food deserts.

While the government can improve low-income people’s access to healthy food to some extent, local actions often have a stronger and more immediate influence．Community gardens, independent food stores, and farmers’ markets are all examples of local actions that can take the place of the opening of a major chain supermarket. These efforts can be extremely beneficial, not only in providing people with access to healthier foods, but also in producing a sense of community in the neighborhoods.
