Dementia doesn’t always start with memory loss. One of the earliest signs might appear on your plate. Experts warn that sudden changes in eating habits could signal a shift in brain function — often before other symptoms become visible. Here are 10 key food-related signs to watch for.
Favorite Foods Suddenly Rejected
A person may abruptly dislike meals they used to love, with no clear reason. This sudden aversion can be one of the first red flags.
Craving Foods They Once Avoided
Someone who previously avoided certain foods — like a lifelong vegetarian — may suddenly develop a strong desire to eat them.
A Growing Sweet Tooth
People with dementia, particularly frontotemporal types, often develop an intense craving for sugary foods and desserts.

Texture Sensitivities
Changes in how food feels — not just how it tastes — may emerge. Crunchy or soft foods might feel unpleasant or unfamiliar.
Eating at Odd Times
Someone may begin eating at inappropriate or unexpected times, such as late at night or during conversations, ignoring social norms.
Loss of Control Over Appetite
An uncontrollable urge to eat, even when not hungry, may become noticeable, especially in cases of behavioral-variant dementias.
