Mom (87) is so weak she can hardly walk. She is very confused at times and she hardly eats anything. She said nothing tastes good. Advice?

Debi, have your Mom checked for an Urinary Tract Infection. Such an infection in an older person can cause an array of issues, and can even mimic dementia.

As for food, I agree with TNtechie's post regarding some reasons. Also, as we age we all will experience a lack of taste for food except for sugary items. I could tell from my parents [90+] grocery list, there were a lot of sweet products.

And lately I found out that that toothpaste can cause a lack of taste especially if the toothpaste has whiteners and mouth wash included. I tried an organic toothpaste just for the heck of it, and what a difference. Even my sig other, who was reluctant at first, noticed a difference.

Anyway, food for thought.

I would get her to the doctor. She could be dehydrated. Low potassium.

Dental health issues can change taste, some medications change taste and unfortunately sometimes dementia changes taste too. Sometimes depression and the effort needed to eat certain foods can be a problem too. Since most people seem to retain a preference for sweet foods, I would try offering smoothies, milkshakes, applesauce, watermelon, cantaloupe, puddings, meatloaf, soups, mashed or baked potatoes/sweet potatoes, etc. One relative who didn't care for ensure drinks liked them when blended with crushed ice and a little half and half or ice cream to thicken it. My mother eats more when the meal is served with her favorite drink - coffee or lemonade.
