Are there any healthy foods that seniors can eat without cooking?

I’m not sure what you mean by cooking. If you are talking about not preparing anything and order, there are tons of high-quality restaurants dear seniors can go to. But if you mean not heating anything, I recommend raw veganism. All you need to do is just mix some ingredients. The leading food would be salad, of course, and nuts, seeds, and fruits in between. It’s a super healthy diet, and there’s no need to cook. Also, vegan restaurants can provide nutritious food.
