Why do some people hate the taste of beer? Genetics determine the taste of beer.

"The bitter taste of beer triggers one of our evolutionary switches, which exists to keep us away from potentially toxic foods and water sources, and the trigger is stronger among some people.
"If the idea of a beer makes you feel sick, you may not be alone."
But even with so many people, we have an unavoidable question: Why do some people hate the taste of beer? The problem boils down to genetic factors, and genetic information can affect how your brain handles bitter tastes and iced drinks.
is that the bitter taste of beer actually triggers one of our evolutionary switches, which exists to keep us away from potentially toxic foods and water sources, and the trigger is even stronger among some.
but first, let's get to know the bitter taste of beer.
you may remember what you learned in science classes, and there are five different taste cells in our taste buds that help us perceive salty, sweet, sour, spicy and bitter taste.
once the taste buds recognize a particular taste, the taste receptor transmits this information to the brain stem through nerves. "If you think of a taste receptor as a lock, you can open it with only one special key," said Dr. Virginia Utermohlen Lovelace, an emeritus retired associate professor in the Department of Nutritional Sciences at Cornell University in New York,
.
detects the bitter taste, the cells connected to the receptor send a message to the brain, which is bitter.
" there are as many as 25 different taste receptors in the body to identify bitter tastes.
, by contrast, there are only two receptors in the human body that identify salty tastes.
beer is mostly bitter from hops, which contain alpha and beta acid and low levels of alcohol.
So when you taste a small mouthful of beer, three of the 25 receptors that recognize bitter taste recognize these flavors and send a strong bitter message to the brain.
but what makes this bitter taste difficult to swallow? If the next time your friends are happy to introduce you to a new beer, you can tell them that their quirky tastes are at odds with evolutionary instincts.
humans have evolved bitter taste receptors for their own safety, in order to help humans identify toxic foods. "The bitter taste receptor is seen as an early warning system for toxic substances,"
researchers said in a 2009 study.
many toxic compounds may taste bitter, but toxicity does not seem directly to the degree of bitterness of the compound.
", "In other words, when a food or drink tastes bitter and makes it difficult for you to swallow, it doesn't mean they're going to poison you."
this will also lead us to the field of genetic diversity, which we often say is genetic variation.
although the human body has so many taste receptors used to detect bitter taste, it is certain lying that this is a genetic excess phenomenon.
TAS2R16, one of 25 bitter taste receptors, has 17 genetic polymorphisms, including a variant associated with alcohol dependence, according to a 2017 study published in the journal Scientific Reports.
Lovelace explains that one of the easiest ways to identify bitter taste sensitivity is to see the number of taste buds in your mouth.
the more taste buds you have, the more likely you are to hate beer brewed by hops.
however, bitter taste receptors are not the only variants that work.
the carbonation in beer opens up our "cold" receptors (the same temperature receptors that can feel the cool taste of mint).
) Lovelace says there are genetic variations in cold receptors, so even if you may not be sensitive to the bitter taste of beer, the cold signals from cold receptors may make beer less popular. "If you're sensitive to the bitter taste of beer or other drinks, there are ways to help you suppress the sensitivity of bitter taste receptors, " says lovelace,
.
sweet and savoury foods can help us turn off the function of bitter taste receptors, which is why humans invented beer nuts and why tequila is salted.
You're more likely to taste the unique taste when you get rid of the bitter taste of beer.
