Americans' notoriously unhealthy diets are seeing a few improvements, according to analysis in the Journal of the American Medical Association. Compared with a decade ago, consumption of fruits and vegetables, processed meat, saturated fat and sodium has not changed much. But Americans are eating more whole grains, nuts, seeds, fish and shellfish and drinking fewer sugary beverages. While 46% of adults still have poor diets, this is down from 56%.

Alas, the gains have not stretched equally across demographics. Diet quality for many minorities and people with lower incomes has not improved; in some cases it has worsened.
