Diet quality among US adults improved modestly between 1999 and 2020, researchers have found.

However, they also found that the number of Americans with poor diet quality remains stubbornly high. Most notably, disparities persist and, in some cases, are worsening.

Poor diet continues to take a toll on American adults. Its a major risk factor for obesity, type 2 diabetes, cardiovascular disease, and certain cancers, and more than one million Americans die every year from diet-related diseases, according to the Food and Drug Administration.

Poor diet and food insecurity is also costly, attributing to an estimated $1.1 trillion in health care expenditures and lost productivity. These burdens also contribute to major health disparities by income, education, zip code, race, and ethnicity.

While weve seen some modest improvement in American diets in the last two decades, those improvements are not reaching everyone, and many Americans are eating worse, says Dariush Mozaffarian, cardiologist and director of the Food is Medicine Institute at the Friedman School of Nutrition Science and Policy at Tufts University at Tufts University, and senior author of the study published in the Annals of Internal Medicine.

Our new research shows that the nation cant achieve nutritional and health equity until we address the barriers many Americans face when it comes to accessing and eating nourishing food.

The researchers investigated data from 10 cycles of the National Health and Nutrition Examination Survey between 1999 and 2020, a nationally representative survey that includes repeated 24-hour dietary recalls, where people report all foods and beverages consumed during the prior day. The study analyzed 51,703 adults who completed at least one valid 24-hour recall, with 72.6% having done two recalls.

They measured diet quality using the American Heart Association diet score, a validated measure of a healthy diet that includes components like fruits, vegetables, beans and nuts, whole grains, sugary beverages, and processed meat.

They found that the proportion of adults with poor dietary quality decreased from 48.8% to 36.7% over these two decades, while those with intermediate diet quality increased from 50.6% to 61.1%. They also found that the proportion of adults with an ideal diet improved but remained starkly low, from 0.66% to 1.58%.

Specific changes contributed to these trends, including higher intakes of nuts/seeds, whole grains, poultry, cheese, and eggs. Researchers also found lower consumption of refined grains, drinks with added sugar, fruit juice, and milk. Total intake of fruits and vegetables, fish/shellfish, processed meat, potassium, and sodium remained relatively stable.

When the analysis focused on key subgroups, the researchers found that these improvements were not universal. Gains in dietary quality were highest among younger adults, women, Hispanic adults, and people with higher levels of education, income, food security, and access to private health insurance.

They were lower among older adults, men, Black adults, and people with lower education, less income, food insecurity, or non-private health insurance. For example, the proportion of adults with poor diet quality decreased from 51.8% to 47.3% among individuals with lower income, decreased from 50.0% to 43.0% among individuals with middle income, and decreased from 45.7% to 29.9% among individuals with higher income.

While some improvement, especially lower consumption of added sugar and fruit drinks, is encouraging to see, we still have a long way to go, especially for people from marginalized communities and backgrounds, says first author Junxiu Liu, a postdoctoral scholar at the Friedman School at the time of the study, now assistant professor at the Icahn School of Medicine at Mount Sinai.

We face a national nutrition crisis, with continuing climbing rates of obesity and type 2 diabetes, Mozaffarian says. These diseases afflict all Americans, but especially those who are socioeconomically and geographically vulnerable. We must address nutrition security and other social determinants of health including housing, transportation, fair wages, and structural racism to address the human and economic costs of poor diets.
