24 Oct 2014 --- A new study finds that most U.S. adults fail to meet recommended daily levels of 10 key nutrients, and those with disabilities have even worse nutrition than average. An estimated 10 to 25 percent of U.S. adults fit into one or more category of disability, from those who have difficulties with activities of daily living, such as dressing, bathing and eating, to those who cannot use their legs or struggle to accomplish routine tasks, such as money management or household chores.
