My mother, 82, lives with my husband and me. She has mild dementia. I make a balanced dinner for the three of us every night (protein, vegetables, potatoes or rice) and I make her lunch on most days. Each day or over night she regularly eats up to a 1/2 gallon of ice cream in one sitting or 12 or more cookies at a time. I have tried hiding treats from her (so there some left for us) or I go through periods where I stop bringing sweets in the house. When she can't find sweets she asks me nonstop to go to the store. She will then eat other things to excess--crackers, raisins, yogurt, whatever she can find. She doesn't remember overeating and isn't gaining weight. She also gets angry when I suggest she put the ice cream or whatever away and got very mad when I mentioned it to her doctor. Question: If she's generally healthy (her cholesterol and weight are within normal ranges) does it matter if she eats that much?
