If you put all the food on one single plate, rotate the plate often so the patient gets to see all the food on the plate. Try to serve five or six small meals during the day, instead of three large ones. Patients have short attention spans and cannot deal with long meals. Some patients have trouble swallowing thin liquids. You can use a thickening agent or use things like gelatins, puddings or ice cream.
Some patients lose the ability to taste.
Sensation becomes dulled. Try flavor enhancers on food. Chicken broth can marinate chicken to give it extra flavor. Add bacon or cheese flavors to soups and veggies. Some patients develop tastes for foods they once hated.
