Does she like tuna? Salmon? Steamed or made into tuna fish salad for a sandwich, or salmon burgers? Shrimp? Whatever she will eat. Sometimes the problem is chewing, swallowing, or digesting. Ice cold supplements are stomach chilling and can be uncomfortable.. How about quiches- warm or cool? Omlets? You can get some baby foods mixed in, and minced veggies or meat. Rice, potatoes, breads, and pastas are filling but very little nutrition, so limit them. Is cheese an option? Grilled cheese sandwich? Watch for lactose intolerance- a simple treatment with lactaid or chewable generics. The taste varies on the chewable brands so try a few. I prefer the CVS. Soups can contain nutrition but use higher protein broths rather than water. Smaller more frequent meals are better. Creamed chicken? She may have many old home comfort food recipes she'd like to adapt.
