Overcoming Taste and Appetite Changes after Traumatic Brain Injury

by Alexa Marks, RD

A traumatic brain injury not only affects various facets of life, including memory, cognition, and speech, but can also profoundly alter how we experience taste and appetite. For many individuals, this shift in sensory perception can render familiar foods unappealing, flavorless, or even rancid-tasting, presenting a significant hurdle to obtaining the nutrients and calories necessary for optimal recovery.

In this article, I'll explore practical strategies to help navigate these changes to support your traumatic brain injury recovery.

Toss the salt, squeeze the lemons.
Though it’s tempting to use salt to boost the flavor of foods that seem “flat” or to choose salt-laden prepared options, consider other ways to kick-start flavor.

A sprinkle of lemon juice is a great way to enhance bland-tasting foods and can even increase the absorption of essential minerals. Grated cheeses, like parmesan, are another favorite. Experiment with fresh or dried herbs, salt-free seasonings like Mrs. Dash, and salt substitutes. A drizzle of maple syrup is a healthy way to add sweetness naturally.

Dealing with metallic taste post-TBI.
Sometimes, people who have experienced a TBI report a metallic taste in their mouth. The cause of this side effect can be due to the injury or even medications. Eating with plastic utensils instead of metal ones can be helpful.

Stimulate your other senses.
Smell and taste aren’t the only senses that stimulate our appetite. Touch and sight very much impact how we enjoy food as well.

Sautéing vegetables in extra virgin olive oil is a great way to add an enjoyable crunch to meals. Experiment with grated veggies and fruits, and try beans, nuts, and cereals to add texture. For those experiencing nausea, cold foods may be more palatable than warm or hot foods.

A plate of colorful, healthy is pleasing to the eye and is a good way of making sure you get a range of vitamins and nutrients. I tell my patients to “eat the rainbow” with an array of fresh fruits and veggies (or frozen!) when they can.

Be aware (and beware) of expiration dates.
If you or a loved one with a TBI have a challenging sense of smell and taste, paying attention to the use-by and best-by dates is crucial as it may not be easy to detect if something is spoiled!

Set goals – and an alarm.
If taste changes or lack of appetite makes you disinterested in food, eating can seem like a chore you’d rather avoid. As I mentioned in part I of this series, setting an alarm can be a great way to stay consistent with meals and snacks throughout the day.
