This issue is especially relevant to seniors because difficulty cooking can cause a senior to adopt a diet where the main staple is a pre-packaged meal or an unhealthy indulgence of a particular food group. Even seniors who are attempting to gain weight should eat a balanced diet rather than fill themselves with foods that are high in fat, salt, and sugar or low in nutrients.

Older individuals may be at risk for low B12 due to less intake of foods containing this vitamin and decreased stomach acid secretion, which can inhibit conversion of B12 into a usable form. Vitamin B12 is found naturally only in animal source foods, such as meat, eggs, fish, and dairy products. It also can be added to fortified foods such as breakfast cereals in a crystalline form, which is better absorbed by those in the older population. This crystalline form is not dependent on stomach acid for absorption, making it more bioavailable.
The USDA recommends adults at any age should get at least 250 minutes of exercise each week. This can include gentle activities, such as yoga, walking, or swimming, which are also beneficial because they minimize the impact to your joints. Some types of weight-bearing activity—like weight lifting, dancing, step aerobics, or basketball—may also help preserve lean muscle mass.
If you don’t think you or your loved one is getting adequate minerals and nutrients from the food you eat, see a registered dietitian, nurse practitioner or doctor to get a prescription for a multivitamin. Our bodies need adequate vitamin D to absorb calcium. Food is the best way to obtain nutrition, but it can be difficult to achieve adequate intake through food alone. If symptoms of weakening bones or osteoporosis are already present, then a multivitamin with vitamin D added is the more suitable choice.
While one highly publicized study suggested that those who are moderately overweight have slightly longer lifespans, other studies, such as this one at Oxford University, associated being moderately overweight with a decreased lifespan. The overweight, or obese, are said to experience lifespans 10 years less than average according to the Oxford study.
