Wife soon may need mainly soft foods - mashed potatoes, soups, etc. Can you suggest other foods?

She will be happiest if you can take the foods you would normally enjoy and modify them. Obviously carrot sticks and steaks are no longer possible, but a grated carrot slaw or a tender meatloaf are still a possibility. If you want to go completely soft diet there are still countless options... quiche and custards, stews and soups, any well cooked vegetable, soft sandwiches like tuna, egg or chicken salad, pasta casseroles, almost any slow cooker recipes, hummus and refried beans... Then there are endless dessert possibilities, fruit crisps and puddings, cakes, my grandmother used to enjoy cookies dunked in her tea... I hope this gives you some ideas!

I have been blending my husbands food for about 1 year now.
I make a lot of soup, stew, as well as many other things that can be processed.
Much easier on him and I have to worry less about pocketing.
At the beginning I diced many things salads and most meals were chopped like you would chop for a toddler. But now it is all pureed.
I am thickening liquids as well so almost anything that has a soft pudding like texture is how the meals are served. Although he will completely enjoy a piece of cake. Soft enough for him so that even if it does not get chewed completely it will go down.
Get one of the little "bullet" type blenders and start by roughly chopping anything that you are having then progress to a full puree when needed.
My husband has also lost teeth and is not compliant last dental visit and the only thing that could be done now is to pull the teeth and I do not want to put him through that ordeal particularly with anesthesia and it's side effects on people with dementia.

A food mill that cranks food through small holes would be a help. I have used one for apple sauce made with unpeeled apples. I've seen small ones advertised for processing baby food. Another possibility along the same lines is a Champion macerator. I was once served frozen bananas processed in one with cinnamon. It was delicious and much like ice cream.

Just another thought - one of the reasons it's important to involve a speech therapist and determine the level of swallowing difficulty is the close distinction between some types of acceptable foods. E.g., and unfortunately, the healthier unbleached flour breads with various seeds, and those lucious thick artisan breads with varied toppings, can be harder to eat than the bland white bread which is thinner and (in my opinion) less healthy and tasty.

Good luck on your quest to adapt to this new phase of aging.

A food processor can be helpful. If your local stores don't sell them, you can get an inexpensive one on Amazon. I like to put lettuce in mine. The processor chops/grinds the lettuce into very fine pieces, almost a mush. Then I top it with my favorite dressing, which happens to be tahini (sesame butter).

How about a juicer for being able to eat raw veggies to deliver the enzymes he can't get. Just do some reading first on limiting carrots, beets, and juicing too many fruits. But a small apple juiced with kale, or cabbage, or greens is tasty and also helps keep ya regular. I got a juicer from Amazon for about $50 and it works great. It's a Hamilton Beach. You can also find juicing combinations for all kinds of illnesses too so you can use food as medicine or food as pleasure too.

The first thing that came to mind is spaghetti sauce with garden veggies. Oatmeal, cream of rice/wheat, cold cereal soaked with milk, in addition to the ideas suggested by others all give options for something solid & soft.

Thanks for more ideas, everyone!

Jimmy, is your wife still at home? Do you have any home care prescribed by one of her physicians? If so, ask for speech therapist to examine her swallowing functions and determine if there's any aspiration.

It would be helpful to make this distinction, as opposed to difficulty swallowing because of the lost teeth. And given that Alzheimer's is involved, from what I've read there eventually can be swallowing dysfunction to the point of aspiration.

I think your first step is to get an evaluation to determine what level of dysphagia she has. There are different levels, with guidelines on food that's acceptable and that which is not.

I recently posted a similar question; the responses were suggestive, helpful and excellent. You might want to look at the posts of those who responded:

https://www.agingcare.com/questions/Does-anyone-have-experience-with-sourcing-food-for-a-mechanical-soft-diet-I-need-some-help-urgently-203290.htm

Don't be thrown off by the question of a supplier; there are still issues discussed by those who posted which address home food preparation as well.

FYI, with the help of a very competent and dedicated speech therapist, she provided clarification that there was no aspiration, a critical factor for anyone with swallowing difficulties. The issue now is focused more on what's chewable and what's not easily chewable.

My husband who had difficulties to eat and swallow, was prescribed high protein sip feed with fibre -Apricot-Peach, Chocolate, etc...- ("Fresubin").
Which he found very nice and helped him.

I have received a lot of helpful answers.

I thank you all.
I pray for all caregivers watching over our spouses.
