Americans get bombarded with promotions for unsubstantiated diet fads on the internet, are exposed to dubious weight-loss branded foods in grocery stores, and often struggle to eat nutritiously. The Dietary Guidelines for Americans recommend a balanced diet of two and a half cups of vegetables, two cups of fruit, six ounces of grains, three cups of dairy, five and a half ounces of protein, and 27 grams of oil every day. This diet is well-balanced, but it is neither practiced by, nor accessible to, all Americans (Figure 1).
Increasing numbers of Americans do not eat healthful diets. In 2018, the National Health and Nutrition Examination Survey found that one in three Americans eats fast food on any given day. Moreover, both rural and urban Americans report that lack of time and access to nutritious foods prevents them from cooking healthy meals. Indeed, a 2017 study indicated that the higher prices of healthy foods - nearly double those of unhealthy foods - can play a role in the U.S. population’s failure to achieve a nutritious diet. When healthy food cost even 14 percent higher than unhealthy food, there was a 24 percent decrease in consuming a high-quality diet. Unfortunately, an unhealthy diet can lead to a variety of health issues, such as obesity, type-2 diabetes, heart disease, and an increased risk of some cancers. To reverse poor health metrics such as the 42.4% of American adults over 20 years of age who suffered from obesity in 2018, policymakers and health experts alike hope to make healthy diets more accessible to all Americans.
