07 Aug 2017 --- Older adults with poor appetites eat much less protein and dietary fiber than those with healthier appetites, according to a study published in the Journal of the American Geriatrics Society. Older people also eat fewer solid foods, protein-rich foods, whole grains, fruits and vegetables. The study is the latest to make clear the benefits of improving nutrition in older adults, as it also found that people with poor appetite did eat or drink more dairy foods, fats, oils, sweets and sodas compared to older adults who reported having very good appetites.
