Should the elderly follow a low-sodium (salt) diet if they have high blood pressure? Perhaps!  A low-sodium diet can help keep high blood pressure under control, and  in doing so, may prevent individuals from having a stroke or heart  attack. Studies have shown the benefits of therapy to reduce blood  pressure in older adults up to 80 years of age. After age 80, the data  are less clear as to possible benefit.
  Everyone  is different. If individuals are healthy and active, and are able to  stick to a low-sodium diet (sometimes called a low-salt diet), than by  all means they should do so. However, if they are in frail health and  have a poor appetite, restricting foods that are high in sodium  sometimes is not in their best interest.
   
  
Quality of life
  Is  it OK to allow the elderly who have high blood pressure to eat  high-sodium foods? It is hard to say “yes” or “no” without knowing more  about the person’s eating habits, medicines, and medical condition.  Every situation is different. However, it is important to consider  quality of life for older individuals. If bacon is something they really  want, perhaps you can compromise on how often and how much. Try buying  the lower-sodium variety of bacon, or, if they are truly insistent and  get pleasure from eating this food, perhaps you should give in and let  them enjoy bacon as part of an overall healthy diet. 
   
  
Low-fat diet for individual with weight loss
  Because  so many elderly people have medical problems and/or are taking many  medicines, it is hard to sort out if a low-sodium diet will lower blood  pressure. In many cases, a diet will not hurt and might help. However,  nutrition experts who work with the elderly agree that one way to  improve the intake of a poor eater is to “liberalize” the diet. This  means letting the elderly eat what they want and stopping any dietary  restrictions. This change often improves food intake, increases quality  of life, and results in better resistance to illnesses.
