You might easily gain access to fresh fruit and vegetables，but this isn't the case in some parts of America．The U．S．has many areas that are considered as food deserts，which are defined as parts of the country short of fresh fruit，vegetables and other healthy food，usually found in poor areas．
   Food deserts are urban areas where the nearest grocery store is more than 1 mile away，and rural areas where the nearest grocery store is more than 10 miles away．According to the USDA，19 mil-lion Americans-or 6.2% of the population-live in places that can be considered as food deserts．
   The issue isn't necessarily about the difference in cost between healthy and unhealthy foods in these areas but it's about a lack of access to healthy choices at all．And，with the lack of healthy food choices，these areas typically have a large supply of unhealthy foods sold at fast-food companies and convenience stores．
   Eating unhealthy foods can lead to overweight，which puts people at risk for all kinds of major health issues，including high blood pressure，heart disease，and some cancers．
   But some people，especially those who cannot afford a car，are stuck with eating what's readily available．In the case of food deserts，it's usually the type of food that can lead to over- weight．Studies have shown that this is likely to be a problem in low-income areas．When money is not enough，people tend to buy foods that last longer and remove food waste，which is a waste of their limited income．
   Lack of access is only one part of the problem，however．A study published in 2018 found that food inequality wasn't removed．The bigger issue was likely the lack of education and nutritional knowledge in these communities，which prevents people with lower incomes from understanding the benefits of healthy eating．
   While overweight is a significant issue in these communities，the cost of unhealthy eating isn't just physical．A study found that 71 billion dollars in healthcare costs due to chronic diseases could be saved through healthier eating．
