How Food Cravings Change with Dementia

Many people with dementia experience sudden changes in appetite preferences and an increase in unhealthy cravings. As the disease progresses, taste buds diminish, insulin in the brain can drop and some people experience intense cravings for high-calorie foods. How Food Cravings Change with Dementia

Appetite Changes As A Result of Dementia

As most caregivers know, many people who have dementia experience sudden changes in appetite which can lead to appetite loss, weight loss or increased cravings of sugary foods and weight gain. Often people with dementia don’t taste food and experience flavor like they once did, which can change appetite preferences. Because taste buds are diminished as people age, people with dementia opt for heavy foods or foods with a lot of flavor, like sugary sweets.

Some researchers also believe that there is a link between type 2 diabetes and Alzheimer’s, even going so far as to call Alzheimer’s a third type of diabetes. Researchers have found that the brain actually produces insulin, just like the pancreas. The amount of insulin produced in the brain drops as Alzheimer’s progresses, which leads to brain cell death, especially in the parts of the brain responsible for memory.

Further linking sugary cravings and dementia, recent studies have shown that when dementia attacks the dorsolateral prefrontal cortex, unhealthy cravings increase. That part of the brain is responsible for self-restraint in our diet. Thus, when a person has dementia and that particular cortex is hijacked, they often experience preferences for high calorie foods.

Managing and Addressing Cravings

Whether your loved one is craving sugar and experiencing weight gain or you are having trouble getting him or her to eat at all, there are few basic guidelines to ensure proper nutrition.

1. Eat in a quiet and calm room with limited distractions so that your loved one can focus on eating.
2. Eat meals together which can increase the likelihood that your loved one will eat the healthy meal provided.
3. Pack in protein. Even if your loved one cannot chew meat well, try eggs, milk-based pudding, or even protein powder.
4. Cut food into small pieces to make eating easier if your loved one can no longer use utensils.
5. Puree vegetables and add them to a shake if your loved one will not eat vegetables on their own.
6. Strengthen the prefrontal cortex responsible for dietary self-restraint by avoiding alcohol, getting adequate sleep, and exercising.
7. At the end of life, allow them to indulge. Registered Dietician, Jillian Ball of Ball & Associates Nutrition Counseling says:

“Food is one of the last things people can enjoy when they’re sick.”

She cautions that if they still have a long life ahead of them to watch their sugar intake and monitor blood sugar if they have diabetes.

    Food is indeed one of the best ways to open thoughts. I give my mom lots of outside experiences involving great food. It is impossible to measure the pleasure or good life of this, but it warms me when my mom says “this is really good”.

    Has anyone had the experience of having a dementia patient not know when they are full after eating dinner? My Mom keeps eating anything that is on the table despite having had a good portion for dinner.

      Hi Regan,

      Yes, I know exactly what you’re describing. My grandmother with dementia eats breakfast, lunch and dinner with snacks in between, but doesn’t recall eating all the time. She especially craves sugar and sweets and we’ve found that monitoring her eating and allowing her to enjoy puddings, like this blog article suggests, has been helpful to us.

  • Giving special attention to a person who has dementia is very important, knowing what kind of food to give them like sweets will help them eat their meal. I want to thank you for this post this helps a lot.

  • William Patterson

    My mom fights every night at dinner time. She is only 64. She has moderate frontotemperal dementia. She keeps gaining weight because we talk her into finishing her meals. They are not big meals, just enough to satisfy her. We are all skinny so I am not over feeding her just a fyi. She is only 130 lbs but carrying weight in her stomach. Any advise would be awesome.

    • Vanesa

      Hi Mr. Patterson,
      I first want to say I’m very sorry about your mother’s health condition. I’ve recently listened to health summits including dementia and Alzheimer’s. Please research the benefits of coconut oil and essential oils on these specific conditions. Drs. Normally say there’s nothing to do except put the patient on toxic drugs until. But please know, there is help. It’s possible that this condition can be reversed. Please research.
