Research: the love of coffee is caused by genes in the body.

Those who drink more coffee are more likely to have a gene that helps their livers break it down If you struggle to get through the day without a constant supply of coffee or tea, it may be down to more than just personal taste. Research shows some of us inherit genes which make us more reliant on caffeine. Those with the 'caffeine addict' genes need to drink more coffee or tea to get the same buzz.

Coffee has been integrated into our daily life to a certain extent as a "cultural symbol". Many white-collar workers who need to work hard have even reached the point that "you can't live without coffee." at least one cup of coffee a day has become a very important part of our lives. Some studies have analyzed that the love of coffee is not acquired. The love of coffee is "born" and is caused by the genes in the body. If you want to force yourself to "quit coffee" for a day, you can't just control your willpower, scientists say. Your "coffee gene" makes it impossible to erase coffee from your mind.

This could also help to explain why chocolate is more irresistible to some than others. The intriguing finding comes from a U.S. Study scrutinising the DNA and diets of 45000 people, one of the first to examine links between foods and genes. This flagged up two genes associated with the high intake of tea, coffee, chocolate and caffeinated soft drinks such as colas. One-CYP1A2-is key to the breakdown of caffeine in the liver. The other, called AHR, regulates the first.

Experts apply the "chocolate gene" to explain the "coffee gene". They analyze that people can't resist the magic of coffee as much as they can't resist the magic of chocolate. This interesting US study confirmed the relationship between human DNA and food for the first time, and experts gradually established the relationship between "food" and "gene" by investigating more than 40, 000 volunteers. In the study, in addition to the genetic effects of coffee, there were also drinks such as tea, chocolate and Coca-Cola. Experts have found that the metabolic activation of CYP1A2 in the human body is an important reason why people are unable to extricate themselves from coffee.

Researcher Neil Caporaso said: 'It's been known for decades that this CYP1A2 gene is what metabolized caffeine. 'But using new technology, what we showed for the first time is that it appears responsible for the inherited differences in how people drink coffee. 'The point is that the way we drink caffeine is not just random-it's related to the genetic hand of cards you were dealt. 'If you break it down more quickly, you require more caffeine to achieve the same "buzz" or to avoid withdrawal after stopping all caffeine.'

Researcher Neil Caporaso said: "people who carry the CYP1A2 gene are more likely to become addicted to coffee. We found for the first time through new technology that our addiction to coffee is based on genes in the body. " (compiled by Wei Fangyuan)
