Whether it’s a last-minute meal or a dip that makes veggies that much more appealing to eat, peanut butter is a lifesaver–and now there’s yet another reason to praise its gooey goodness.
Peanut butter can detect early-stage Alzheimer’s disease, according to a new study from the University of Florida.
All it takes is a tablespoon of peanut butter (creamy or chunky) and a ruler, says researcher Jennifer Stamps. Sniffing the nut butter will clue doctors into your brain’s wellbeing.
In early-stage Alzheimer’s the olfactory sense declines, affecting the ability to smell. Stamps found that she could detect this decline by testing people’s ability to sniff out peanut butter.
In the study, participants closed their eyes and blocked one nostril at a time. People who experienced a dramatic difference in smell between the left and right nostrils were those doctors determined to be in an early stage of the disease.
“At the moment, we can use this test to confirm diagnosis,” says Stamps. “But we plan to study patients with mild cognitive impairment to see if this test might be used to predict which patients are going to get Alzheimer’s disease.
Since many tests for detection are expensive, the practicality of the peanut butter test (as silly as it sounds) is actually ground-breaking research in dementia and Alzheimer’s Disease.
