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.
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.

Anyway, food for thought.
