When they're eating less, and needing fewer calories, it can be challenging to get the right nutrition, especially when interest in nutrition and cooking is waning. Older bodies also have more trouble compensating for nutrient deficiencies, so it's easy to understand why older Americans are at a disproportionate risk for poor nutrition. Whether at age 65 or 85, many older people eventually face one or more problems that interfere with their ability to eat well. Depression also is a big factor, she said. And decreased sensitivity of taste and smell can cause decreased appetites.
Social isolation is a common obstacle to proper nutrition.
Older people who find themselves single after many years of living with another person may find it difficult to be alone, said Trish Vignati, a registered dietitian with the Southeast Dairy Association. They may lose interest in preparing or eating regular meals. Family members and friends can help by checking to ensure that the older person is eating adequately. They also can prepare foods for the older person and join him or her for meals. Look around the community for organizations such as church groups, hospitals and senior centers that offer opportunities for socializing and meals.
