She's catching onto my tricks. She won't drink any of the flavored beverages like she used to. She'll usually drink the nutritional drinks (Ensure, Boost), but not always. I don't know if there should be a daily limit on how many of those she should drink. Other beverages that she would probably drink are full of sugar or acid (like soda) and I'm not sure she should have those. I don't want to make milkshakes because she seems to have issues with too much dairy. Oddly, the one time I gave her a diet cola, she complained it was "too burny" even though I watered it down just like they do at her favorite fast food place. Popsicles are out this time of year as she says it's too cold for those.
I could probably fatten her up a bit if I just fed her pure junk food (chips, chocolate, candy, cookies, etc.), but that's just asking for all sorts of other problems like constipation. The meals I cook are low-fat and healthy because I need to eat that way. I'm not sure what to give her that isn't full of sodium or sugar. Mac & cheese? She has trouble with pizza and Hot Pockets. Sometimes she eats more than I do and I'm the one that gains the weight. Ugh!
Instead of the crappy little cookies they offer for a snack, I purchase Atkins cookies & cream bars and chocolate & coconut bars. She loves them and they’ve got protein and fiber. She also likes the Belvitas chocolate filled biscuit cookies (also healthy) and has them with a cup of tea as a snack. So they may be ideas to help you get some extra good calories into her. I wouldn’t rely too much on processed foods due to the bad ingredients. They don’t serve many processed foods at the NH, more balanced meals, protein, veggie, starch, fruit, dessert etc.
When mom ended up in rehab after a fall, I talked about my concerns with their dietitian and the speech therapist. The therapist sat with her at meals for several days and discovered that eating and drinking was more of a texture issue than a flavor issue with my mom. It also seems that "sweet" is the particular taste bud she favored. Mom transitioned about a month ago to long term care there, and she actually eats and drinks a wide variety now and her nutritional status is much improved. They serve her a small 3 oz. nutritional shake-type drink as soon as she sits down at the table before breakfast and lunch, and a high protein dessert (Magic Cup) after lunch and dinner, along with a completely pureed diet. She also gets a small glass of water and a small glass of a diluted cranberry juice at every meal. She drinks and eats it all. The variety and a regular schedule for meals seems to have helped her quite a bit. Also I asked the aides and med tech when they come to her room to please pour her a glass of water. I keep a pitcher (with a water filter) in her room on her little fridge.
Maybe your mom's physician could recommend a dietitian consult?
Homemade soups can also add fluids. I have a basic low salt potato soup that is good plain or can be dressed up with some cheese and broccoli. Vegetable beef is a favorite with my mother and adds lots of fiber and veggies to the diet. Chicken noodle is an old stand by. Although we occasionally eat some canned soups (like tomato) most have too much salt to indulge very often.
