We should eat right at every stage of life, but this is especially true for older adults. Most don’t get all the nutrients they need, which can lead to malnutrition. They could be depressed, have difficulty chewing or take medicines that suppress appetite. Not eating well can lead to digestive and heart problems, muscle weakness, a weakened immune system and a greater chance of infections. If you think a loved one may be malnourished, observe his or her eating habits and look for outward signs of malnutrition (easy bruising, poor wound healing, dental problems, weight loss). Or ask your loved one’s doctor to test his or her protein levels, which can help spot malnutrition.
