Love of coffee is explained by genetics

Some people need three cups of strong coffee to wake up, others need a rather weak latte. A new study has found that this reaction to caffeine is due to genetic variations.

A new study has identified six new genetic variations that are directly related to coffee consumption. There are now eight of them – the first two were opened in 2011.

Researchers at Harvard University say the human response to coffee is genetic. This explains why some coffee energizes the whole day, while others have no beneficial effect. Ultimately, it all comes down to caffeine.

Scientists studied 2.5 million genetic variations of more than 120,000 people of different sexes who regularly consumed coffee. Comparing genetic data, they identified genes associated with coffee drinking habits. Some gene variants are involved in the metabolism of caffeine, others are responsible for the pleasure of its use. Therefore, people with different genetics need to drink different amounts of coffee to achieve the same effect.

This is another example of how our genetics affect our addictions.

The findings could help doctors and nutritionists approach determining a safe dose of coffee more individually. As with smoking and alcohol consumption, this will significantly reduce health risks.

The study was published in the journal Molecular Psychiatry.
