Talk about grapevine expectations.
Dr. Jason Singh, a primary care physician based in Virginia, is sharing a sweet tip for managing stress eating. He recommends that frozen grapes melt in your mouth.
“Cold temperature activates TRPM8 receptors in the mouth, which then trigger the release of dopamine — and this is responsible for pleasure, similar to what we seek during stress,” Singh explained on TikTok on Tuesday.
Transient receptor potential melastatin subtype 8 (TRPM8) receptors are primarily activated by temperatures below your core body temperature, usually around 79 degrees Fahrenheit or 26 degrees Celsius.
They really kick in when temperatures reach 50 degrees Fahrenheit or 10 degrees Celsius, researchers have found.
Activated TRPM8 receptors can suppress the release of CGRP, a neuropeptide that depletes dopamine in the brain, and increase levels of interleukin-10, an anti-inflammatory protein in the body that responds to stressful situations.
Singh also reports that the cooling sensation from grapes stimulates the parasympathetic nervous system, slowing heart rate and breathing, lowering blood pressure and cortisol levels, and promoting digestion.
Levels of cortisol, the body’s main stress hormone, have been shown to decrease in cold situations, such as immersion in cold water.
And finally, Singh said chewing grapes stimulates the salivary glands to produce saliva, tricking your brain into thinking you’ve eaten something substantial and are full.
“So the next time you’re feeling stressed, reach for some frozen grapes,” Singh said.
Grapes are ripe for weight loss. They are relatively low in calories – one cup (about 92 grams) contains 62 calories.
There’s also plenty of water and fiber in grapes, and they’re a rich source of vitamins C and K and the heart-healthy antioxidant resveratrol.
