Genetic Factors Influence Coffee Consumption, Study Finds

A recent study published in the American Journal of Clinical Nutrition reveals that genetic factors significantly influence coffee consumption habits. Conducted by a team of Australian scientists, the study examined nearly 400,000 individuals aged between 39 and 73. The researchers concluded that people instinctively regulate their coffee intake, independently of medical guidelines about its potential harms.

The study suggests that human genes actively help in understanding the required amount of coffee, thereby protecting against excessive consumption. Additionally, multiple studies have shown that caffeine improves mental performance, alertness, general motor skills, learning, and memory. Previous research also indicated that coffee consumption could induce genetic changes within DNA, potentially passing these changes to future generations.

This groundbreaking research highlights how genetics can influence habitual behaviors, providing a deeper understanding of individual differences in coffee consumption.
