My husband has vascular dementia and alzheimers. He hasn't eaten meat for 40 years but always enjoyed different sorts of fish and liked Quorn/Linda McCartney type vegetarian meals. He has never liked much in the way of vegetables. Lately he us refusing to eat more than a few mouthfuls of the food I've regularly cooked, I've tried Wiltshire Farm foods, ready meals from M&S, etc but most is ending up in the bin. He cannot tell me what he would eat. He eats his lunchtime sandwich, cheese, salmon, cream cheese, paste, etc so I'm wondering if I should just give him a different sandwich at dinnertime. He would happily eat cake and biscuits at any time of day. I would be grateful for any advice.
