Human DNA has been the subject for research for as long as one can remember and will continue to be so for various different researches to be done on humans in the future. The reason being an obvious one, you can completely decode humans through their gene sample or DNA and can conduct experiments by comparing it to human behaviors.
As small as it may sound, the drinking habits of a person and their preferences can also be justified by their genes or at least researchers are trying to come on a point where they can be confident about this proposition as well. To be precise, let’s focus on two beverages in particular which you might be consuming as a result of how your genes respond to them; coffee and tea.
Both tea and coffee contain bitter taste and are caffeinated. It is this quality of these drinks that provides a comparison which makes them products that can be studied to observe human behavior. The gene that was used as a sample to carry on with this experiment was the taste gene. The results of the experiment might not be completely accurate or cannot be considered to be enough to actually draw a definite conclusion out of it but it surely helped the researcher in noticing patterns of coffee and tea drinkers and how it varies.
UK Biobank was used to conduct the research as it is the repository for genetic data for medical research. The research was conducted for more than 400,000 participants which is a huge number and required several years for the process to get accomplished, researchers from different states gathered to make this happen.
The results were not quite direct or gave a black and white picture but it surely indicated how the difference is based on the sensitivity and perception of the genes for caffeine or other bitter tastes. One of the reasons was the additional bitter element of quinine in coffee which is not present in tea and hence it depends on the extent to which your genes are sensitive to bitter tastes.
Overall, the research was able to set grounding for further experiments and it also proved to be useful in determining how this simple statement that bitter is always bad is no more than a generalization.
